[006] In the vehicles described in Patent Documents 1 and 2, the loads that are supported by the right front wheel and the left front wheel are transferred to the linkage mechanism by means of the right damper or the left damper. Loads are transferred to the right side portion or the left side portion from the right damper or the left damper. Loads are transferred to the upper transverse portion and the lower transverse portion from the right side portion or left side portion. Loads are further transferred to the body, which is positioned on the periphery of the steering axle from the upper transverse portion and the lower transverse portion.
[007] The linkage mechanism includes bearings that are provided between the right side portion or the left side portion and the upper cross portion and the lower cross portion and bearings that are provided between the upper cross portion and the lower cross portion and the bodywork . These bearings function not only to allow the right side portion or the left side portion to rotate smoothly with respect to the upper cross portion and the lower cross portion, but also transfer the loads borne by the linkage mechanism to the bodywork.
[008] In addition, the right side portion, the left side portion, the upper cross portion and the lower cross portion are formed highly rigid to improve the function of smoothly turning and the function of transferring the loads. This fact increases the right lateral portion, the left lateral portion, the upper transverse portion and the inferior transverse portion in size. This results in the enhancement of the binding mechanism that is made up of those portions. In addition, the mobile range of the link mechanism is also further expanded.
[009] The vehicles described in Patent Documents 1 and 2 include the linkage mechanism which is provided on the periphery of the steering axle, and this linkage mechanism moves as the bodywork leans. Because of this, on the vehicle including the tiltable bodywork and the two front wheels, the plate components have to be provided so that the plate components do not interfere with the moving band of the link mechanism. In the vehicle which includes the tiltable bodywork and the two front wheels, this tends to increase the construction on the periphery of the steering axle.

[020] a handlebar that is provided at the upper end portion of the steering axle; and
[021] a slewing transfer mechanism that transfers one turn of the steering shaft that corresponds to a handlebar operation to the right damper and the left damper, where in the linkage mechanism,

[024] The right side portion, the left side portion, the upper transverse portion and the lower transverse portion that make up the linking mechanism are formed highly rigid to reinforce the function of smoothly turning and the function of transferring the loads. This fact increases the right lateral portion, the left lateral portion, the upper transverse portion and the inferior transverse portion in size. This results in the enhancement of the binding mechanism that is made up of those portions. In addition, the mobile range of the link mechanism is also further expanded. The vehicle which includes the tiltable bodywork and the two front wheels has on the periphery of the steering axle the large connecting mechanism which moves as the tilted bodywork.
[025] Because of this, on the vehicle including the tiltable bodywork and the two front wheels, the plate components have to be provided so that the plate components do not interfere with the moving band of the link mechanism. In the vehicle which includes the tiltable bodywork and the two front wheels, this tends to increase the construction on the periphery of the steering axle.
[026] Next, the inventor analyzed in detail the function of the binding mechanism. The linking mechanism has the function of allowing the right side portion or the left side portion to rotate smoothly in relation to the upper transverse portion and the lower transverse portion and the function of allowing the upper transverse portion and the lower transverse portion to rotate smoothly in relation to the bodywork. Furthermore, the linkage mechanism has the function of transferring the loads borne by the right side portion and the left side portion of the bodywork. This analysis found the fact that the load borne by the linkage mechanism includes loads in the direction of the rotation axes of the upper transverse portion, the lower transverse portion, the left lateral portion and the right lateral portion and loads in directions that extend in the direction up and down the body and which are vertical to the axes of rotation. Furthermore, the analysis found the fact that the good functioning of the linking mechanism is easy to be maintained by making the rigidity of the upper transverse portion which includes the piece of the part which is supported on the side portions in the right end portion and the portion. of left end and which is supported on the bodywork in the middle portion for loads in the direction of the rotation axes equal to the rigidity of the lower transverse portion which includes the piece of the part which is supported on the side portions in the right end portion and the portion left-hand end and which is supported on the bodywork in the middle portion for loads in the direction of the rotation axes.
[027] According to the vehicle of the invention, the mobile band of the connecting mechanism can be changed from a simple shape like a rectangular parallelepiped to an irregular shape, making the volume of the upper transverse portion that includes the piece of the part that is supported on the side portions at the right end portion and the left end portion thereof and which is supported on the bodywork at the middle portion thereof which differs from the volume of the lower transverse portion which includes the piece of the portion which is supported on the side portions of the right end portion and the left end portion thereof and which is supported on the bodywork in the middle portion thereof. This can increase the degree of freedom in the design of the steering axis periphery. As a result of this, although several components of the plate which differ in size and the linking mechanism are arranged on the periphery of the steering axle, it is possible to restrict the widening of the periphery of the same. In addition, the good functioning of the connecting mechanism is easy to be maintained, since the rigidity of the upper transverse portion which includes the part piece which is supported on the side portions of the right end portion and the left end portion and which is supported on the bodywork in the middle portion for loads in the direction of the rotation axes is made to equalize the rigidity of the lower transverse portion which includes the part piece which is supported on the side portions of the right end portion and end portion left which is supported on the bodywork in the middle portion for loads in the direction of the rotation axes.
[028] Therefore, in the vehicle that includes the tiltable bodywork and the two front wheels, it is possible to restrict the widening of the peripheral construction of the steering axle that is above the two front wheels, while the function of the mechanism connection is maintained.
[029] In the vehicle, according to the invention, the linkage mechanism may be such that the upper transverse portion that includes the piece of the part that is supported in the right end portion and the left end portion and that is supported in the portion. The middle portion differs in material from the lower transverse portion which includes the portion piece which is supported on the right end portion and the left end portion and which is supported on the middle portion.
[030] According to the vehicle of the invention which includes the tiltable bodywork and the two front wheels, in the case where the upper transverse portion is formed of a material that is more rigid than the material of which the transverse portion lower is formed, the volume of the upper transverse portion which includes the piece of the part which is supported on the side portions of the right end portion and the left end portion and which is supported on the bodywork in the middle portion can be made smaller than the volume of the lower transverse portion which includes the piece of the part which is supported on the side portions of the right end portion and the left end portion and which is supported on the bodywork in the middle portion, while the rigidity of the upper transverse portion for the loads in the direction of the axes of rotation are kept identical to that lower transverse portion. In the case where the lower transverse portion is formed of a material that is more rigid than the material from which the upper transverse portion is formed, the lower transverse portion may have a smaller shape than the upper transverse portion, while the rigidity of the portion upper transverse which includes the piece of the part which is supported on the side portions of the right end portion and the left end portion and which is supported on the bodywork in the middle portion for loads in the direction of the rotation axes is kept identical to that portion bottom transverse which includes the portion piece which is supported on the side portions of the right end portion and the left end portion and which is supported on the bodywork in the middle portion. This allows the mobile band of the linking mechanism to be changed from a simple shape like a rectangular parallelepiped to an irregular shape. This can increase the degree of freedom in the design of the steering axis periphery. As a result of this, although several components of the plate which differ in size and the linking mechanism are arranged on the periphery of the steering axle, it is possible to restrict the widening of the periphery of the same.
[031] In the vehicle according to the invention, the linking mechanism may be such that the upper transverse portion that includes the piece of the part that is supported in the right end portion and left end portion and that is supported in the middle portion is identical in material for the lower transverse portion which includes the portion piece which is supported on the right end portion and the left end portion and which is supported on the middle portion.

This can increase the degree of freedom in the design of the steering axis periphery. As a result of this, although several components of the plate which differ in size and the linking mechanism are arranged on the periphery of the steering axle, it is possible to restrict the widening of the periphery of the same.
[033] In the vehicle, according to the invention, the bodywork may include a connecting support portion that supports the upper transverse portion that includes the piece of the part that is supported in the right end portion and the left end portion and which is supported on the middle portion and the lower transverse portion which includes the piece of the portion which is supported on the right end portion and the left end portion and which is supported on the middle portion in a rotatable manner, and the connecting mechanism may be such that a volume of a front portion of the upper transverse portion which lies further forward than the connecting support portion in the direction of the upper right axis which differs from a volume of a rear portion of the upper transverse portion which is located further forward than the connecting support portion.

This can increase the degree of freedom in the design of the space on the periphery of the rear portion of the upper transverse portion. As a result of this, although several components of the plate which differ in size and the linking mechanism are arranged on the periphery of the steering axle, it is possible to restrict the widening of the periphery of the same.

This can increase the degree of freedom in the design of the space in the front portion of the vehicle, about the periphery of the upper transverse portion. As a result of this, although several components of the plate which differ in size and the linking mechanism are arranged on the periphery of the steering axle, it is possible to restrict the widening of the periphery of the same.

This can increase the degree of freedom in the design of the front peripheral space of the upper transverse portion. As a result of this, although several components of the plate which differ in size and the linking mechanism are arranged on the periphery of the steering axle, it is possible to restrict the widening of the periphery of the same.

[090] In this mode, the upper transverse portion 51 is made of a single plate-shaped piece that extends in the direction to the left and to the right, when viewed from the front of the vehicle. The upper cross portion 51 is provided further forward to the front of the vehicle than the main tube 211. The upper cross portion 51 includes an upper middle bearing 511 which is provided to a middle portion of the upper cross portion 51 with respect to the to the left and right of the body 21 and a pair of upper right bearing 512 and upper left bearing 512 which are provided in right and left portions of the upper cross portion 51 in the left and right direction of the Bodywork 21. An upper middle shaft M1 which constitutes a center of rotation of the upper middle bearing 511, an upper left shaft M2 which constitutes a center of rotation of the upper left bearing 512 and an upper right shaft M3 which constitutes a center of rotation of the bearing top right 512 so that the corresponding axes of rotation are parallel to each other.
[091] The upper cross portion 51 is mounted on the main tube 211 through the upper middle bearing 511. This allows the upper cross portion 51 to be supported on the main tube 211 so as to rotate around the upper middle axis M1 with respect to main tube 211.
[092] The upper cross portion 51 is connected to an upper portion of the left side portion 53 and an upper portion of the right side portion 54 through the upper left bearing 512 and the upper right bearing 512, respectively. This allows the upper transverse portion 51 to rotate about the upper left axis M2 and the upper right axis M3 with respect to the left side portion 53 and the right side portion 54, respectively.

Lower Transverse Portion
[094] The lower transverse portion 52 has a volume that differs from the upper transverse portion 51. The lower transverse portion 52 extends in the left and right direction of the body 21 when viewed from the front of the vehicle. A length of the left and right direction (length in the left and right direction) of the lower cross portion 52 is substantially equal to a length of the left and right direction of the upper cross portion 51. Lower cross portion 52 is provided below upper cross portion 51 with respect to the up and down direction of body 21. Lower cross portion 52 is adjusted to have a stiffness that is substantially equal to that of upper cross portion 51. stiffness of these transverse portions will be described in detail later.
[095] The lower transverse portion 52 includes a pair of the transverse lower front 52a1 and transverse lower rear 52a2 that hold the main tube 211 between them in the front and rear direction of the body 21 and a connecting portion 52b where the front. bottom transverse 52a1 and bottom transverse 52a2 are fastened together with screws. The connecting portion 52b is a portion that is formed integrally with the lower transverse front portion 52a1. The connecting portion 52b is provided in a position where the connecting portion 52b does not interfere with the main tube 211, the left side portion 53 and the right side portion 54, even when the connecting mechanism 5 is actuated to function as it will. described later. In this embodiment, the transverse lower front part 52a1 and the transverse lower rear part 52a2 are defined, so that a thickness in the front and rear direction of the bodywork 21 is thinner than a half of a thickness of the upper transverse portion 51 in the front direction. and rear of the bodywork 21. In addition, the upper transverse portion 51, the lower transverse front 52a1 and the lower transverse rear portion 52a2 are formed of the same material, e.g. steels having the same modulus of elasticity.
[096] In the pair of the lower transverse front 52a1 and the lower transverse rear 52a2 of the lower transverse portion 52, a lower middle bearing 521 which is provided in a middle portion in the left and right direction of the bodywork 21 and a pair lower left bearing 522 and lower right bearing 522 which are provided in left and right portions in the left and right direction of the bodywork 21. An M4 lower middle shaft which constitutes a center of rotation of the middle lower bearing 521 and a lower left shaft M5 and a lower right shaft M6 which constitute the centers of rotation of the lower left bearing 522 and the lower right bearing 522, respectively, are provided so that the corresponding axes of rotation are parallel to each other. In addition, the lower middle axle M4, the lower left axle M5 and the lower right axle M6 are also equipped so as to be parallel to the upper middle axle M1, the upper left axle M2 and the upper right axle M3. In addition, the positions of lower left bearing 522 and lower right bearing 522 in the left and right direction of bodywork 21 are set to be the same as the positions of upper left bearing 512 and upper right bearing 512 in the direction to to the left and to the right of the bodywork 21 with the vehicle 1 resting in the vertical state.
[097] The lower cross portion 52 is mounted to the main tube 211 through the lower middle bearings 521 in a position that lies below the upper cross portion 51 with respect to the up and down direction of the body 21. This allows the lower transverse portion 52 is supported on the main tube 211 so as to rotate about the lower mean axis M4 which constitutes the center of rotation of the lower middle bearing 521 with respect to the main tube 211.
[098] The lower transverse portion 52 is connected to a lower portion of the left side portion 53 and a lower portion of the right side portion 54 through the lower left bearing 522 and the lower right bearing 522, respectively. This allows the lower transverse portion 52 to rotate about the lower left axis M5 and the lower right axis M6 relative to the left side portion 53 and the right side portion 54, respectively.
[099] In this modality, the lower transverse portion 52 is constituted by a combination of two parts. Namely, the lower transverse portion 52 includes:
[0100] The part 52a2 that supports the lower portion of the right side portion 54 at the right end portion thereof, through the lower right bearing 522, so as to rotate around the lower light axis M6 which is parallel to the upper right axis M3 and supports the lower portion of the left side portion 53 at the left end portion thereof, through the lower left bearing 522, so as to rotate around the lower left shaft M5 which is parallel to the upper left shaft M2, which is supported on the bodywork 21, in the middle portion thereof, through the lower middle bearing 521, so as to rotate around the lower middle axle which is parallel to the upper middle axle and which is positioned further back than the main tube 211, and
[0101] The part (the part that consists of the constituent parts indicated by reference numeral 52a1 and reference numeral 52b) that is positioned in front of the part just described above, to be connected to the part, which supports the part the lower right side portion 54 at the right end portion thereof, through the lower right bearing 522, so as to rotate around the lower right axis M6 which is parallel to the upper right axis M3 and supports the lower portion of the left side portion 53 in the left end portion thereof, through the lower left bearing 522, so as to rotate around the left lateral axis M5 which is parallel to the upper left axis M2 and which is supported on the bodywork 21 in the middle portion thereof, through the lower middle bearing 521 so as to rotate around the lower middle shaft which is parallel to the upper middle shaft.
[0102] In this way, the upper transverse portion 51 is supported on the main tube 211 so as to rotate around the upper middle axis M1 which is positioned above the left front wheel 31 and the right front wheel 32 with respect to the upward direction and down the body 21. The lower transverse portion 52 is supported on the main tube 211 so as to rotate around the lower middle axis M4 which is positioned above the left front wheel 31 and the right front wheel 32 and which is positioned below the upper middle axis M1 with respect to the up and down direction of the body 21. The upper transverse portion 51 and the lower transverse portion 52 are both positioned above the left front wheel 31 and the right front wheel 32 with respect to the direction to up and down bodywork 21.
[0103] Thus, by being configured in the manner described above, the link mechanism 5 can operate within a plane containing the left side portion 53 and the right side portion 54. It should be noted that the link mechanism 5 is mounted on the main tube 211. Due to this, even though the steering axle 60 is connected in association with the steering of the handlebar 23, the connecting mechanism 5 has not turned with respect to the bodywork 21.
[0104] Fig. 4 is a drawing showing an upper portion of the link mechanism 5 as seen from a side of the vehicle with the vehicle at rest in the vertical state. As shown therein, in this embodiment, a lower surface C of the upper transverse portion 51 is situated between an upper surface A of a lower transverse front portion 52a1 constituting a front portion and an upper surface B of the lower transverse rear portion 52a2 constituting a portion. the rear of the lower transverse portion 52 relative to the front and rear direction of the bodywork 21.
[0105] Although the link mechanism 5 with the vehicle resting in the vertical state is shown in Fig. 4, the position relationship just described above will be maintained, even when the link mechanism 5 is actuated to function as the vehicle body leans, as will be described later. That is, even when the link mechanism 5 is actuated to function, the lower surface C of the upper cross portion 51 is situated between the upper surface A of the lower cross front portion 52a1 constituting the front portion of the lower cross portion 52 and the surface upper B of the lower rear transverse portion 52a2 which constitutes the rear portion of the lower transverse portion 52 with respect to the front and rear direction of bodywork 21.
[0106] In other words, the linking mechanism 5 is provided, so that a front end of the upper cross portion 51 and a front end of the lower cross portion 52 are situated at different positions in the direction of the upper right axis M3. Parentheses
[0107] As shown in Fig. 2, the first bracket 335 is provided to a lower portion of the left side portion 53. The first bracket 335 is connected to the left damper 33. The first bracket 335 is mounted so as to rotate with respect to the left side portion 53. The tie 6 is mounted on the first bracket 335 so as to pivot with respect thereto. An axis of rotation, in which the first support 335 and the left side portion 53 rotate in relation to each other, and an axis of rotation in which the first support 335 and the rod 6 rotate in relation to each other are parallel to a direction in which the left lateral portion 53 extends (a left direction axis N1).
[0108] The second support 336 is provided in a lower portion of the right side portion 54. The second support 336 is connected to the right damper 34. The second support 336 is mounted so as to rotate with respect to the right side portion 54. tie-rod 6 is mounted on the second bracket 336 so as to pivot relative thereto. An axis of rotation in which the second support 336 and the right side portion 54 rotate with respect to each other and an axis of rotation in which the second support 336 and the rod 6 rotate with respect to each other are parallel to one direction. wherein the right side portion 54 extends (a right steering axis N2). steering axis
[0109] Steering axle 60 is supported in bodywork 21 between left member 53 and right side portion 54 in the left and right direction of bodywork 21. An upper end portion of steering axle 60 is provided further up in the up-and-down direction of the bodywork 21 than the middle lower axle M4. Steering axle 60 can rotate around a medium steering axle Z which extends in the up and down direction of the body 21. The handlebar 23 is provided on the upper end portion of the steering axle 60. The tie rod 6 ( an example of a swivel transfer mechanism) transfers a swivel of the steering shaft 60 that corresponds to an operation of the handlebar 23 to the right damper 34 and the left damper 33.
[0110] When the steering axle 60 rotates as a result of the handlebar 23 being steered, the tie rod 6 moves in the left and right direction of the bodywork 21. The first bracket 335 then rotates around the axle of rotation connecting the first bracket 335 to the left side portion 53 as the tie rod 6 moves. This moves a link portion 52b, where the first bracket 335 connects to the left damper 33 in the left and right direction of the bodywork 21, and the left front wheel 31 rotates about a second axis of rotation 312.
[0111] In this way, the first bracket 335 transfers the steering from the handlebar 23 to the left front wheel 31. Likewise, the second bracket 336 transfers the steering from the handlebar 23 to the right front wheel 32. Vehicle Body Tilt
[0112] Fig. 5 is a full front view of vehicle 1 that tilts the vehicle body at an angle T in the left and right direction relative to a perpendicular direction from the state shown in Fig. 2. When vehicle 1 is caused to lean with respect to the perpendicular direction, linkage mechanism 5 is actuated to function.
[0113] When this occurs, the upper transverse portion 51 and the lower transverse portion 52 are converted horizontally in the left and right direction, while the directions in which they extend is kept parallel to the surface of road G. The upper transverse portion 51 and the lower transverse portion 52 rotate about the upper left axis M2 and the lower left axis M5, respectively, with respect to the left lateral portion 53. In addition, the upper transverse portion 51 and the lower transverse portion 52 rotate about the upper right axis M3 and the lower right axis M6, respectively, with respect to the right lateral portion 54.
[0114] In this way, when the vehicle is viewed from the front, with the vehicle at rest in the standing state, the upper transverse portion 51, the lower transverse portion 52, the left side portion 53 and the right side portion 54 they form a rectangle, and when the vehicle is forced to lean, the link mechanism 5 works, so that the rectangle changes to a parallelogram, as the vehicle is forced to lean even more.
[0115] In the following description, an area in which the upper transverse portion 51, the lower transverse portion 52, the left side portion 53 and the right side portion 54 move, may be referred to as a movable band of the link mechanism 5.
[0116] In this mode, the linking mechanism 5 operates so that a left end of the upper cross portion 51 moves more to the left horizontally than a left end of the lower cross portion 52. When the link mechanism 5 operates from this In this way, the left shock absorber 33 and the right shock absorber 34 tilt in relation to the vertical direction. When vehicle 1 tilts to the left with respect to the vertical direction, in the manner described above, the state of vehicle 1 changes from the state shown in Fig. 2 to the state shown in Fig. 5.
[0117] Vehicle 1 according to this mode can be turned on, causing the vehicle body to lean when vehicle 1 is running. In addition, the directions of the left front wheel 31 and right front wheel 32 can also be changed by operating the handlebar 23. Stiffness of Cross Portions and Method for Measuring Stiffness
[0118] Next, the stiffness of the upper transverse portion 51 and the lower transverse portion 52 will be described. In the following description, the stiffness of the upper cross-section 51 and the lower cross-section 52 (hereinafter, when both cross-sections do not have to be discriminated against each other, the upper cross-section 51 and the lower cross-section 52 are referred to simply as a transverse portion) means the difficulty that the transverse portion has in deflecting when a force acting in the front and rear direction of the vehicle body is exerted on the transverse portion. In the following description, the upper cross-section 51 and the lower cross-section 52 may be referred to as a full cross-section.
[0119] The left front wheel 31 and right front wheel 32 of vehicle 1 are each independently supported. Because of this, there are situations where different forces are exerted on the left front wheel 31 and the right front wheel 32 at different times. For example, when supports are applied or vehicle 1 passes over irregularities in the road surface, an external force is transferred to the link mechanism 5. While this occurs, there are situations where the force components in the front and rear direction are different in magnitude or direction are exerted to the left and to the right of the transverse portion or where a component of force in the front and rear direction is exerted to the left and to the right of the transverse portion at different periods. Even in such a case, the transverse portion is necessary to have a certain difficulty to deflect when a force in the front and rear direction is exerted on it, so as to maintain the smooth functioning of the link mechanism 5. To satisfy this requirement, the the right side portion 54, the left side portion 53, the upper cross-section 51 and the lower cross-section 52 of the vehicle 1 of this embodiment have high rigidities to maintain the smooth operation of the link mechanism 5.
[0120] The right side portion 54, the left side portion 53, the upper transverse portion 51 and the lower transverse portion 52, which form the link mechanism 5 are formed highly rigid to improve the smoothly rotating function and the function to transfer loads. This fact increases the external forms of the right side portion 54, the left side portion 53, the upper transverse portion 51 and the lower transverse portion 52. In addition, this also increases the external form of the connecting mechanism 5 which is constituted by those portions. . Furthermore, the mobile range of the connecting mechanism 5 is also further increased. The vehicle which includes the tiltable body 21 and the two front wheels 31, 32 includes on the periphery of the steering axle 60 the large link mechanism 5 which moves like the tiltable body 21. Because of this, on the vehicle, including the tiltable body 21 and the two front wheels 31, 32, the plate components need to be provided so that the plate components do not interfere with the moving range of the link mechanism 5. Because of this, on the vehicle including the tiltable body 21 and the two front wheels 31, 32, the construction on the periphery of the steering axle 60 tends to be increased in size.
[0121] Next, the inventor analyzed in detail the function of the linking mechanism 5. The linking mechanism 5 has the function of allowing the right side portion 54 or the left side portion 53 to rotate smoothly with respect to the upper transverse portion 51 and the lower transverse portion 52 and the function of allowing the upper transverse portion 51 and the lower transverse portion 52 to rotate relative to the body 21. In addition, the link mechanism 5 has the function of transferring the loads borne by the right side portion 54 or the left side portion 53 of the bodywork 21. This analysis found the fact that the load carried by the linkage mechanism 5 includes the loads in the direction of the axes of rotation (the upper middle axle M1, the upper left axle M2, the axles upper right axis M3, the lower middle axis M4, the lower left axis M5 and the lower right axis M6) of the upper transverse portion 51, the lower transverse portion 52, the left lateral portion 53 and the by right side tion 54 and loads in directions which extend in the up and down direction of the bodywork 21 and which are vertical to the axes of rotation. Furthermore, the analysis also found the fact that the good functioning of the linkage mechanism 5 is easy to be maintained by making the stiffness of the upper cross portion 51 of the load in the direction of the rotation axes equal to the stiffness of the lower cross portion 52.
[0122] The stiffness of the transverse portion of the connecting mechanism 5 includes a stiffness component that is assigned to the shape, thickness, volume and the like of the cross portion itself and a stiffness component that is assigned to the type, size, and the like, of the bearing upper middle 511 or the lower middle bearing 521. Then it is possible to know the stiffness of the cross section based on an offset of the cross portion that will be measured, as will be described below. It is shown that the smaller the displacement, the greater the rigidity.
[0123] Fig. 6 shows schematic drawings showing how to assess the stiffness of the upper transverse portion 51. Fig. 6 (a) is a perspective view of an upper portion of the connecting mechanism 5, and Fig. 6 ( b) is a plan view of the upper portion of the connecting mechanism 5. Fig. 7 shows schematic drawings showing how to assess the stiffness of the lower transverse portion 52. Fig. 7(a) is a perspective view of the upper portion of the connecting mechanism 5, and Fig. 7(b) is a plan view of the upper portion of connecting mechanism 5.
[0124] As shown in (a) in Fig. 6, the lower cross portion 52 is removed from the main tube 211. In this state, the upper middle bearing 511, the upper left bearing 512 and the upper right bearing 512 are held mounted on the upper cross portion 51. An offset X1 of the upper cross portion is measured when a rear test force F1 in the direction of the upper right shaft M3 is exerted on the upper right bearing 512 with the lower cross portion 52 removed.
[0125] Likewise, a displacement X2 of the upper transverse portion 51 is measured when a force that is the same in magnitude and direction (a rearward direction in the direction of the upper left axis M2) as the test force F1 is exerted on the left upper bearing 512 with lower cross portion 52 removed.
[0126] Then, as shown in Fig. 7, the upper cross portion 51 is removed from the main tube 211. In this state, the lower middle bearing 521, the lower left bearing 522 and the lower right bearing 522 are kept assembled in the lower cross portion 52. An offset X3 of the lower cross portion 52 is measured when a force that is the same in magnitude and direction (a rearward direction in the direction of the lower right axis M6) as the test force F1 is exerted on the bearing. lower right 522 with upper cross portion 51 removed.
[0127] Likewise, a displacement X4 of the lower transverse portion 52 is measured when a force F2 that is the same in magnitude and direction (a rearward direction in the direction of the lower left axis M5) as the test force F1 is exerted on the lower left bearing 522 with the upper cross portion 51 removed.
[0128] As in the upper left bearing 512 and the lower left bearing 522 or the upper right bearing 512 and the lower right bearing 522, the test force is exerted only on one of the left and right bearings of the upper cross portion 51 and the portion lower transverse 52. In so doing, a force which is exerted on the upper transverse portion 51 and the lower transverse portion 52 when supports are applied or passenger vehicles by irregularities in the road surface is ridiculed.
[0129] When offsets X1, X2, X3 and X4 are measured as described above, on vehicle 1 of this mode, offsets X1 to X4 are set to be equal to each other. Here, it is understood that displacements X1 to X4 are defined to be equal to each other, when the difference between a larger displacement and a smaller displacement in terms of absolute value is equal to or less than 20% of an average value of the offsets X1 to X4.
[0130] In vehicle 1 of this embodiment, the upper cross portion 51 does not have a member corresponding to the connecting portion 52b of the lower cross portion 52. That is, the upper cross portion 51 is provided further forward than the main tube 211, and no transverse portion 51 is yet provided rearward than the main tube 211. In contrast to this, the lower transverse portion 52 has the front and rear portions of the main tube 211.
[0131] In addition, the upper middle bearing 511 is provided further forward than the main tube 211, and no bearing is yet provided to the rear than the main tube 211. In contrast to this, the lower middle bearings 521 are provided on the front and rear sides of the main tube 211 . The same bearings are adopted for the upper middle bearing 511 and the lower middle bearing 521.
[0132] Due to this, in the vehicle 1 of this modality, the rigidity of the upper transverse portion 51 is made equal to that of the lower transverse portion 52 by adapting at least one of the following configurations (1) to (4) or one combination of them. (1) A thickness in the front and rear direction of the upper transverse portion 51 is adjusted to be greater than the thickness of each lower transverse front portion 52a1 and the lower transverse rear portion 52a2 which form the lower transverse portion 52. (2) A upper transverse portion 51 is made larger than the lower transverse front portion 52a1 which constitutes the front portion of the lower transverse portion 52. (3) The upper middle bearing 511 of the upper cross portion 51 is made larger than the lower middle bearings 521 of the lower cross portion 52. (4) The upper middle bearing 511 of the upper cross portion 51 is made of a plurality of bearings. All settings (1) to (4) can be adopted. Functions and Advantages
[0133] According to the vehicle 1 of the modality, the mobile band of the connecting mechanism 5 can be changed from a simple shape like a rectangular parallelepiped to an irregular shape, making the volume of the upper transverse portion 51 that includes the piece of the part that supports the right side portion 54 and the left side portion 53 and that is supported on the bodywork 21 differs from the volume of the lower transverse portion 52 that includes the piece of the part that supports the right side portion 54 and the left side portion 53 and which is supported on the body 21.
[0134] The inventor has found that it is preferable from the analyzes to make the stiffness of the upper cross portion 51 equal to the stiffness of the lower cross portion 52 to allow the proper functioning of the link mechanism 5. It is general practice and it is reasonable to make the section upper cross section and lower cross section identical to each other in order to make them with the same rigidity.
[0135] However, the inventor has come to know that the efficiency of using the peripheral space of the steering axle 60 cannot be increased in the case of the upper transverse portion and the lower transverse portion which are determined to be identical. Next, the inventor has realized that it is useful to make the volume of the upper transverse portion 51 that differs from the volume of the lower transverse portion 52 to increase the efficiency of utilization of the peripheral space of the steering axle 60 at the same time as the volume of the portion. The upper transverse portion 51 differs from the volume of the lower transverse portion 52. In the case where the volume of the upper transverse portion 51 differs from the volume of the lower transverse portion 52, the upper transverse portion 51 and the lower transverse portion 52 may have different shapes. The linking mechanism 5 is allowed to have an irregular movable band, making use of the configuration in which the upper transverse portion 51 and the lower transverse portion 52 are of different shapes, thus making it possible to make effective use of the peripheral space of the steering axle 60 Furthermore, the upper transverse portion 51 and the lower transverse portion 52 are determined to have the same rigidity, and therefore, the smooth functioning of the link mechanism 5 is easy to be maintained.
[0136] In this mode, the upper transverse portion 51 is positioned further forward than the main tube 211 and no transverse portion is yet provided rearward than the main tube 211. In addition, the lower transverse portion 52 includes the portion which is positioned further back than the main tube 211 and the part which is positioned further forward than the main tube 211. This makes the movable band of the connecting mechanism 5 in a way that, in the forward direction and rear of body 21, a dimension increases from top to bottom relative to the up and down direction of body 21. This makes it easier to eliminate board components in an area on the periphery of steering axle 60 and near the portion top of the link mechanism 5.
[0137] Specifically, the upper transverse portion 51 is made of a single plate-shaped member, and as shown in Fig. 4 and no member of the connecting mechanism 5 is provided in the upper portion of and further back than the mechanism. link 5. This allows an upper portion of the space where the link mechanism 5 operates (the movable strip of the link mechanism) smaller than the movable strip of the link mechanism of Patent Document 1. Then, the bodywork or accessories can be arranged in the upper space defined further to the rear than the link mechanism 5. Alternatively, the front cover 221 is designed smaller in size by a surface corresponding to the upper rear space. Here, accessories include an ABS (Anti-lock Brake System) hydraulic unit, headlamp, horn, turn signals, radiator, battery, anti-theft device, brake hoses, brake wire, screws for brake hose and brake wire, cover of the body, several meters, and the like.
[0138] In the space defined in the front portion of the vehicle, a body member is designed large or an additional member is arranged in the upper space that is more inclined at the rear than the link mechanism 5, through which it is possible to increase rigidity of the vehicle. Alternatively, the space can be used as a space for accessories or as a stowage space. By doing this, the positions where the equipment must be deposited can be freely conceived in the front portion of the vehicle. Furthermore, it is possible to improve the exterior design.
[0139] In this way, according to the modality vehicle, the degree of freedom in the design of the periphery of the steering axle 60 can be increased by changing the mobile range of the link mechanism 5 from the simple shape as a rectangular parallelepiped to the irregular shape. As a result of this, although various components of the plate which differ in size and the linking mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible to restrict the periphery widening.
[0140] Furthermore, although the volume of the upper cross portion 51 that includes the piece piece is made to differ from the volume of the lower cross portion 52, which includes the piece piece to change the movable band of the connecting mechanism 5 from the simple shape as a rectangular parallelepiped to the irregular shape, the rigidity of the upper cross portion 51 for the load in the direction of the rotation axis is kept equal to that of the lower cross portion 52. This makes it easy to maintain good functioning of the link mechanism 5.
[0141] It is therefore possible to restrict the widening of the peripheral construction of the steering axle 60 which is above the two front wheels 31, 32 while the function of the link mechanism 5 is maintained in the vehicle 1 which includes the body 21 which can lean and the two front wheels 31, 32.
[0142] In particular, a dial portion and the bodywork are densely arranged behind the main tube 211 in many cases. Because of this, this embodiment in which no upper transverse portion member 51 is provided in the main tube 211 is preferable, as the space can be of effective use for other applications. For example, the front frame 212 can be connected directly to the main tube 211 without interposing a support element or between them, thus making it possible to increase the rigidity of the support frame 212 and the main tube 211.
[0143] In addition, the upper cross portion 51, the lower cross portion 52, the left side portion 53 and the right side portion 54 of the link mechanism 5 are rotatably supported by bearings 511, 512, 521 and 522. This improves the stiffness of the connecting mechanism 5.
[0144] In vehicle 1, according to this embodiment, the material of the upper transverse portion 51 is the same as the material of the lower transverse portion 52 in the link mechanism 5. Although the material of the upper transverse portion 51 is the same as the material of the lower cross portion 52, as described above, the movable band of the connecting mechanism 5 can be changed from the simple shape as a rectangular parallelepiped to the irregular shape, making the volume of the upper cross portion 51 differ from the volume of the lower transverse portion 52. This can increase the degree of freedom in the design of the periphery of the steering axle 60. As a result of this, although several stem components that differ in size and the link mechanism 5 are arranged on the periphery of the axle. direction 60, it is possible to restrict the periphery widening.
[0145] Alternatively, being different from the modality described above, different materials can be used for the upper transverse portion 51 and the lower transverse portion 52 of the connecting mechanism 5. In the case where the upper transverse portion 51 is formed of a material that is greater in stiffness than a material from which the lower cross portion 52 is formed, the volume of the upper cross portion 51 can be made smaller than the lower cross portion 52 at the same time as the stiffness of the upper cross portion 51 for the load in the direction of the axis of rotation equal to that of the lower transverse portion 52. This allows the movable band of the linking mechanism 5 to be changed from simply shape like a rectangular parallelepiped to irregular shape. This can increase the degree of freedom in the design of the periphery of the steering shaft 60. As a result of this, although various plate components that differ in size and the link mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible restrict the expansion of the periphery.
[0146] In contrast to this, in the case where the upper transverse portion 51 is formed of a material that is greater in rigidity than a material from which the lower transverse portion 52 is formed, the volume of the upper transverse portion 51 can be made smaller than that of the lower transverse portion 52 at the same time as the stiffness of the upper transverse portion 51 for the load in the direction of the axis of rotation equal to that of the lower transverse portion 52.
[0147] In vehicle 1, according to this modality, in the link mechanism 5, the volume of the upper transverse portion 51 is smaller than the volume of the lower transverse portion 52. According to the vehicle of the modality that includes the bodywork 21 can be tilted and the two front wheels 31, 32, the volume of the upper transverse portion 51 is smaller than that of the lower transverse portion 52 and, therefore, the movable band of the connecting mechanism 5 can be changed in a simple way. from a rectangular parallelepiped shape to irregular shape, in which the upper portion is smaller than the lower portion. This can increase the degree of freedom in the design of the peripheral space of the upper transverse portion 51, which is located at the front of the vehicle. As a result of this, although various components of the plate which differ in size and the linking mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible to restrict the periphery widening.
[0148] As shown in Fig. 4, in vehicle 1, according to the modality, the body 21 includes the main tube 211 which rotatably supports the upper cross portion 51 and the lower cross portion 52. The upper cross portion 51 is provided in front of the main tube 211 and no members are provided behind the main tube 211.
[0149] According to the vehicle of the embodiment which includes the tiltable body 21 and the two front wheels 31, 32, the upper transverse portion 51 is provided only at the front of the main tube 211, and therefore the movable band of the linking mechanism 5 can be changed from the simple shape as a rectangular parallelepiped to the irregular shape, in which the upper portion is smaller than the lower portion. This can increase the degree of freedom in the design of the periphery of the steering shaft 60. As a result of this, although various plate components that differ in size and the link mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible restrict the expansion of the periphery.
[0150] Being different from the modality that was described above, a configuration can be adopted, in which the upper transverse portion 51 is provided towards the rear of the main tube 211, and no member is provided in front of the main tube 211. Even with this configuration, as with the modality configuration, the movable band of the connecting mechanism 5 can be made in irregular shape, wherein the upper portion is smaller than the lower portion.
[0151] Alternatively, a configuration can be adopted in which the lower transverse portion 52 is provided in front of or behind the main tube 211 and both do not have to be provided. This configuration can also make the movable band of the linking mechanism 5 in an irregular shape, in which a lower portion is smaller than an upper portion.
[0152] As shown in Fig. 4, in the vehicle according to the modality, a front end of the upper cross portion 51 and a front end of the lower cross portion 52 are provided at different positions with respect to the direction of the upper right axle M3.
[0153] According to the vehicle which includes the tiltable body 21 and the two front wheels 31, 32, the front end of the upper cross portion 51 and the front end of the lower cross portion 52 are provided in the different positions in the direction of the upper right axis M3, and therefore, the movable band of the linking mechanism 5 can be changed from the simple shape as a rectangular parallelepiped to a shape that is irregular in the front and rear direction. This can increase the degree of freedom in the design of the periphery of the steering shaft 60. As a result of this, although various plate components that differ in size and the link mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible restrict the expansion of the periphery.
[0154] In the vehicle according to the modality, the link mechanism 5 is such that the rear end of the upper cross portion 51 and the rear end of the lower cross portion 52 are provided at different positions in the direction of the upper right axis.
[0155] According to the vehicle of this modality, the rear end of the upper transverse portion 51 and the rear end of the lower transverse portion 52 are provided at different positions in the direction of the upper right axis M3, and therefore the moving band of the mechanism Link 5 can be changed from the simple shape as a rectangular parallelepiped to a shape that is irregular in the front and rear direction. This can increase the degree of freedom in the design of the periphery of the steering shaft 60. As a result of this, although various plate components that differ in size and the link mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible restrict the expansion of the periphery.
[0156] In the vehicle according to the modality, the main tube 211 that rotatably supports the upper transverse portion 51 and the lower transverse portion 52 supports the steering axle 60 rotationally.
[0157] According to the vehicle 1 of the embodiment which includes the tiltable body 21 and the two front wheels 31, 32, the main tube 211 supports the connecting mechanism 5 which in turn supports the front wheel right 32, left front wheel 31, right damper 34 and left damper 33 and include high rigidity. Due to this, the steering axle 60 is supported by using high rigidity, whereby the configuration in which the steering axle 60 is supported can be simplified. As a result, it is possible to restrict the widening of the peripheral construction of the steering axle 60.
[0158] In addition, the lower transverse portion 52 is configured to include the pair of the lower transverse front 52a1 and the transverse lower rear 52a2 that hold the main tube 211 from the front and rear between them. In the lower transverse portion 52, it is possible to obtain the high rigidity, using the thin plate material.
[0159] Furthermore, the upper cross portion 51 is mounted on the main tube 211 only through the single upper middle bearing 511. In contrast to this, the lower cross portion 52 includes the lower middle bearings 521 which are located at the front and the rear of the main tube 211. That is, the lower transverse portion 52 is supported on the main tube 211 with the two points that are spaced apart from each other in the front and rear direction. By adapting this configuration, the rigidity of the lower transverse portion 52 is easy to be raised. In addition, the loads exerted on the lower middle bearings 521 supporting the lower cross portion 52 can be mitigated. This allows the adaptation of a bearing that has to carry the relatively small load for the application to the lower medium bearing 521, which is needed to support a large load.
[0160] In addition, the upper transverse portion 51 is provided only at the front of the main tube 211, and the lower transverse front portion 52a1 and the transverse lower rear portion 52a2 of the lower transverse portion 52 are provided on both the front sides and the rear sides of main tube 211. By adapting this configuration, the supporting stiffness with which the lower transverse portion 52 supports the left side portion 53 and the right side portion 54 becomes greater than the supporting stiffness with which the The upper transverse portion 51 supports the left side portion 53 and the right side portion 54. Thus, the left side portion 53 and the right side portion 54 are supported by the lower transverse portion 52, which has the greatest support rigidity at positions close to the front wheels 31, 32. This allows the linking mechanism 5 to guarantee the necessary rigidity for the external forces exerted on the front wheels 31, 32 with ease.
[0161] Furthermore, as described in Fig. 4, in this embodiment, the lower surface C of the upper transverse portion 51 is situated between the upper surface A of the lower transverse front portion 52a1 constituting the front portion and the upper surface B of the portion rear lower transverse 52a2 which constitutes the rear portion of the lower transverse portion 52 with respect to the front and rear direction of the bodywork 21. By adapting this configuration, although the link mechanism 5 is actuated to function as a result of the vehicle 1 being used to lean, there is no such situation that the upper transverse portion 51 interferes with the lower transverse portion 52. This allows the distance between the upper transverse portion 51 and the lower transverse portion 52 to be reduced, thus making it possible to reduce a dimension in the up and down direction of the linkage mechanism 5. This allows the space in the front portion of the vehicle to be made of additional effective use.
[0162] Furthermore, in this mode, the displacement of the upper cross portion 51, resulting when the rear test force F1 is exerted on the upper cross portion 51 is equal to the displacement of the lower cross portion 52, resulting when the rear test force F2 is exerted on the lower transverse portion 52, and the displacement of the upper transverse portion 51, resulting when the rear test force F1 is exerted on the upper transverse portion 51 is equal to the displacement of the lower transverse portion 52 that results when the force of back test F2 is exerted on the lower transverse portion 52. Modified Examples
[0163] Thus, although the invention has so far been described using the embodiment thereof, the technical scope of the present invention is not limited by the scope that is described in the embodiment. It is obvious to those skilled in the art to which the invention belongs that various modifications or improvements can be made to the modality.
[0164] For example, in the above modality, the upper transverse portion 51 and the lower transverse portion 52 are described as being formed of the same material and with different volumes, so that the displacements X1 to X4 are made equal, making their volumes different from each other. However, the approach of making the X1 to X4 offsets equal to each other by making the volumes differ from each other is not limited to the approach described in the modality. For example, different materials can be used, and what's more, volumes can also be different.
[0165] For example, in the modality, the upper cross portion 51 can use a material with greater rigidity than a material that the lower cross portion 52 uses. By adapting this approach, the volume of the upper cross portion 51 can be reduced by reducing the thickness of the upper cross portion 51. upper portion of the connecting mechanism 5 can be used for other applications. Namely, this increases the degree of freedom in the peripheral space design of the upper transverse portion 51.
[0166] Furthermore, in the modality described above, the plate members having the same shape are used for the upper cross portion 51 and the lower cross portion 52, and in order for the upper cross portion 51 and the cross portion The lower 52 have the different volumes, the upper transverse portion 51 uses one plate member, while the lower transverse portion 52 uses the two plate members. However, the approach of having the different volumes is not limited to the approach described in the modality. For example, it is possible to adapt an approach of using members that are different in cross-sectional area and cross-shape in addition to the thickness for the upper cross portion 51 and the lower cross portion 52 or an approach of providing or not providing a reinforcing rib. to increase the stiffness in the upper cross portion 51 and the lower cross portion 52. In addition, the different bearings can be used for the upper middle bearing 511 and the lower middle bearings 521. volumes of the upper cross-section and the lower cross-section differ, meaning that a difference in volume that does not largely affect the stiffness of the cross-sections is not included in the above-mentioned volume difference.
[0167] In the modality, the upper space that is behind the connecting mechanism 5 is described as being used for other applications, including the application in which the accessories are arranged in space, the present invention is not limited to them. For example, a configuration can be adapted, in which the rigidities of the upper transverse portion 51 and the lower transverse portion 52 are made equal, and the only upper transverse portion 51 is provided behind the main tube 211, so that the space Front top of the link mechanism 5 can be used for other applications.
[0168] Furthermore, a configuration can be adapted, in which the link mechanism 5 is constructed upside down compared to the construction described in the modality. Specifically, an upper transverse portion 51 has two transverse portions, i.e. an upper transverse front and an upper transverse rear portion which hold the main tube 211 from the front and rear between them, while a single lower transverse portion 52 is provided only on either the front or rear of the main tube 211. While this occurs, a lower front portion or a lower rear portion of the connecting mechanism 5 can be used for other applications.
[0169] Furthermore, in the embodiment described above, while the linking mechanism 5 is described as including the upper transverse portion 51 and the lower transverse portion 52, the present invention is not limited thereto. For example, like the linkage mechanism, a linkage mechanism can be adapted which is configured to have three or more transverse portions, such as a linkage mechanism that includes an upper transverse portion, a lower transverse portion and a middle transverse portion. which is provided between the upper cross portion and the lower cross portion.
[0170] Furthermore, in the embodiment described above, while the upper transverse portion 51 and the lower transverse portion 52 are described as being mounted on the main tube 211 which rotatably supports the steering axis 60, the present invention is not limited to same. For example, the upper cross portion 51 and the lower cross portion 52 may be mounted on a location that extends upward and forward from the front frame 212 or a member that is mounted on the front frame 212, so as to extend up and forward.
[0171] In the modality described above, as shown in Fig. 4, the lower transverse portion 52 includes the transverse lower front 52a1 and the transverse lower rear 52a2 which are respectively connected to the front and rear of the main tube 211, in such a way as to hold the main tube 211 therebetween in the front and rear direction of the bodywork 21. Furthermore, the upper transverse portion 51 is provided only at the front of the main tube 211 with respect to the front and rear direction of the bodywork 21 However, the present invention is not limited thereto.
[0172] For example, as shown in Fig. 8, a configuration can be adapted, wherein an upper transverse portion 51A includes an upper transverse front portion 51A1 and an upper transverse rear portion 51A2 which are individually connected to a main tube 211, in such a way as to hold the main tube 211 therebetween in a front and rear direction of a bodywork 21. When this occurs, the transverse upper front part 51A1 is established, so that the volume of the transverse upper front part 51A1 is greater than that of the upper cross-rear 51A2. By adapting this configuration, compared to a configuration in which the transverse upper front portion 51A1 has a volume that is substantially the same as the transverse upper rear portion 51A2, the degree of freedom in designing a connecting portion of a frame 212 to the main tube 211 can be improved. Note that in the configuration shown in Fig. 8, offsets X1 to X4 are made to be equal to each other.
[0173] In addition, as this occurs, as shown in Fig. 8, the volume of the upper transverse front portion 51A1 can be set to be smaller than the volume of the lower transverse front portion 52a1 which lies at a front portion of the portion. lower cross-section 52.
[0174] It is preferable that no member constituting the connecting mechanism 5 is provided behind the main tube 211, as shown in Fig. 4. In the case where the configuration shown in Fig. 4 is adapted, the front frame 212 has no It is to be connected to the main tube 211, in such a way as to circumvent the transverse upper rear portion 51A2. Because of this, the front frame 212 can be connected to the main tube 211 behind the upper transverse portion 51. In so doing, the rigidity of the front frame 212 and the main tube 211 can be increased without increasing the front portion of the vehicle.
[0175] As shown in Fig. 8, in the vehicle 1 according to the modified example, the bodywork 21 includes the main tube 211 which rotatably supports the upper transverse portion 51A and the lower transverse portion 52A. In the connecting mechanism 5, the transverse upper front portion 51A1 constituting a front portion of the upper transverse portion 51A which lies further forward than that of the main tube 211 in the direction of an upper right axis M3 has a volume less than that of a lower transverse front portion 52a1 which constitutes a front portion of the lower transverse portion 52A which is further forward than the main tube 211.
[0176] According to the vehicle of this modified example which includes the tiltable body 21 and two front wheels 31, 32, the volume of the upper transverse front portion 51A1 constituting the front portion of the upper transverse portion 51A which is located further forward than the main tube 211 is made smaller than the volume of the lower transverse front portion 52a1 which constitutes the front portion of the lower transverse portion 52 which is further forward than that of the main tube 211. Therefore, the movable band of the linking mechanism 5 can be changed from a simple shape like a rectangular parallelepiped to an irregular shape, in which an upper front portion is smaller than a lower front portion. It is possible to increase the degree of freedom in designing a peripheral space of the upper transverse portion 51A1. As a result of this, although various components of the plate which differ in size and the linking mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible to restrict the periphery widening.
[0177] In the vehicle according to the embodiment, the body 21 includes the main tube 211 that constitutes a part of the body 21, which rotatably supports the upper transverse portion 51A and the lower transverse portion 52A. The volume of the upper transverse front portion 51A1 which constitutes the front portion of the upper transverse portion 51A which is more forward than that of the main tube 211 in the direction of the upper right axis M3 which differs from the volume of the transverse upper rear portion 51A2 which constitutes a rear portion of the upper transverse portion 51A which is further back than that of the main tube 211.
[0178] According to the vehicle of the embodiment which includes the tiltable body 21 and the two front wheels 31, 32, the volume of the transverse upper front part 51A1 which is more forward than that of the main tube 211 is made to differ from the volume of the transverse upper rear portion 51A2 which is further back than that of the main tube 211. Therefore, the movable band of the connecting mechanism 5 can be changed from the simple shape as a parallelepiped rectangular to irregular shape. This can increase the degree of freedom in the design of space on the periphery of the rear portion of the upper cross portion 51A. As a result of this, although various components of the plate which differ in size and the linking mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible to restrict the periphery widening.
[0179] In the vehicle according to the embodiment, the body 21 includes the main tube 211 that rotatably supports the upper cross portion 51A and the lower cross portion 52A. In the connecting mechanism 5, the volume of the lower transverse front portion 52a1 which constitutes the front portion of the lower transverse portion 52A which lies further forward than that of the main tube 211 in the direction of the upper right axis M3 which differs from the lower rear transverse portion volume 51a2 which constitutes a rear lower transverse portion 52A which is further back than that of main tube 211.
[0180] According to the vehicle of the embodiment which includes the tiltable body 21 and the two front wheels 31, 32, the volume of the transverse lower front part 52a1 which is more forward than that of the main tube 211 differs from the volume of the transverse lower rear part 52a2 which is further back than that of the main tube 211, and therefore the movable band of the connecting mechanism 5 can be changed from the simple shape as a parallelepiped rectangular to irregular shape. This can increase the degree of freedom in the design of the peripheral space in the rear portion of the lower transverse portion 52A. As a result of this, although various components of the plate which differ in size and the linking mechanism 5 are arranged on the periphery of the steering shaft 60, it is possible to restrict the periphery widening.
[0181] In the vehicle 1 according to this embodiment, the upper transverse portion 51A includes the transverse upper front portion 51A1 (an example of an upper front portion) which is further forward than that of the main tube 211 in the direction of the upper right axle M3 the transverse upper rear portion 51A2 (an example of an upper rear portion) which is further back than that of the main tube 211.
[0182] According to the vehicle 1 of the embodiment which includes the tiltable body 21 and the two front wheels 31, 32, the upper transverse portion 51A includes the piece of the transverse upper front portion 51A1 which lies further down. the front than the main tube 211 and the piece of the upper transverse rear portion 51A2 which is further back than that of the main tube 211, and therefore the balance between the stiffness and volume of the upper transverse portion 51A is easy to be controlled. This can increase the degree of freedom in the design of the periphery of the lower portion of the steering shaft 60. This can increase the degree of freedom in the design of the space on the periphery of the upper cross portion 51. As a result of this, although in various parts of plate with different sizes and the linking mechanism 5 are arranged on the periphery of the steering axle 60, it is possible to restrict the widening of the periphery of the steering axle 60.
[0183] According to the modality, compared to a case where only the upper front part is arranged at the front of the main tube and no part is arranged at the rear of the main tube 211 or a case only the upper rear rear part is disposed at the rear of the main tube and no part is disposed at the front of the main tube, since the upper front part 51A1 and the upper rear part 51A2 keep the main tube between them, it is easy to improve the rigidity of the portion. upper transverse portion 51A without increasing the length of the portion piece in the front and rear direction of the bodywork 21. This restricts the volume of the upper transverse portion 51A from being increased, while increasing the rigidity of the upper transverse portion 51A. This increases the degree of freedom in the design of the space around the periphery of the upper portion of the link mechanism. As a result of this, although various plate parts of different sizes and the linking mechanism 5 are arranged on the periphery of the steering axle 60, it is possible to restrict the widening of the periphery of the steering axle 60.
[0184] In the vehicle according to the invention, the lower transverse portion 52A includes the transverse lower front portion 52a1 (an example of a lower front portion) which lies further forward than that of the main tube 211 in the direction of the lower right axle M6 and the transverse lower tail piece 52a2 (an example of a lower tail) which is further back than that of the main tube 211.
[0185] According to the vehicle 1 of the present invention which includes the tiltable body 21 and the two front wheels 31, 32, the lower transverse portion 52A includes the lower transverse front portion 52a1 which is more closely located. the front than that of the main tube 211 and the piece of the lower transverse rear portion 52a2 which is further back than that of the main tube 211, and therefore the balance between the stiffness and volume of the lower transverse portion 52A is easy to be controlled. This can increase the degree of freedom in the design of the periphery of the lower portion of the steering axle 60. This may increase the degree of freedom in the design of the peripheral space in the rear portion of the lower cross portion 52A. As a result of this, although various parts of the plate with different sizes and the linking mechanism 5 are arranged on the periphery of the steering axle 60, it is possible to restrict the widening of the periphery of the steering axle 60.
[0186] Compared to a case where only the lower front is disposed at the front of the main tube and no part is disposed at the rear of the main tube or a case only at the lower rear is disposed at the rear of the tube main tube and no part is disposed at the front of the main tube, since the lower front part 52a1 and the lower rear part 52a2 hold the main tube 211 between them, it is easy to increase the rigidity of the lower transverse portion 52A without increasing the piece dimension of the part in the front and rear direction of the body 21. This restricts the volume of the lower cross portion 52A from being increased, while enhancing the rigidity of the lower cross portion 52A. This can increase the degree of freedom in the design of the peripheral space in the rear portion of the link mechanism 5. As a result, although various plate parts with different sizes and the link mechanism 5 are arranged on the periphery of the steering axle 60, it is possible to restrict the periphery widening of the steering axle 60.
[0187] In the embodiment and its modified example, while the main tube 211 is described as becoming the connecting support portion, the invention is not limited thereto. The front frame 212 of the body 21 can be used to rotatably support the linkage mechanism 5. In addition, the linkage support portion can be constituted by a piece of part or a plurality of parts. In the case of the connecting support portion being constituted by a plurality of parts, the parts can be joined together by means of welding, gluing or the like. Alternatively, the parts can be joined together with fastening elements such as screws, rivets or the like.
[0188] The upper transverse portion 51 may include a transverse front upper portion which is constituted by a piece piece, a transverse upper rear portion which is constituted by a piece piece and a connecting element which is provided between the front and rear top and which is made up of a plurality of parts. In the case of the connecting support portion being constituted by a plurality of parts, the parts can be joined together by means of welding, gluing or the like. Alternatively, the parts can be joined together with fastening elements such as screws, rivets or the like.
[0189] The lower cross portion 52 may include a lower front cross part that is constituted by a part piece, a lower rear cross part that is formed by a part piece, and a connecting element that is provided between the front and rear and which are made up of a plurality of parts. In case the connecting support portion is constituted by a plurality of parts, the parts can be joined together by means of welding, gluing or the like. Alternatively, the parts can be joined together with fastening elements such as screws, rivets or the like.
[0190] In addition, the right side portion 54 and the left side portion 53 may each be constituted by a piece of the part or a plurality of parts. In the case of the connecting support portion being constituted by a plurality of parts, the parts can be joined together by means of welding, gluing or the like. Alternatively, the parts can be joined together with fastening elements such as screws, rivets or the like.
[0191] In addition, the right side portion 54 and the left side portion 53 may each be constituted by only a portion that is further forward or a portion that is further back in the front and rear direction of the bodywork 21 than the upper transverse portion 51 or the lower transverse portion 52. The upper transverse portion or the lower transverse portion can be arranged between the portions which are arranged at the front and the portions which are arranged at the rear of the right side portion and the left lateral portion.
[0192] In the embodiments described above, the right side portion 54, the left side portion 53 and the main tube 211 are provided in positions that are superimposed on each other when the body 21 is viewed from one side thereof. However, when the bodywork 21 is viewed from the side thereof, the main tube 211 can be provided in a different position from the positions where the right side portion 54 and the left side portion 53 are provided with respect to the direction. front and rear. Furthermore, the angles of inclination of the right side portion 54 and the left side portion 53 with respect to the up and down direction of the bodywork 21 may differ from an angle of inclination of the main tube 211.
[0193] The vehicle, according to the invention, is a vehicle that includes the body 21 that can tilt and the two front wheels 31, 32. The number of rear wheels is not limited to one and therefore the vehicle may include two rear wheels. Whether or not the vehicle includes the body cover that covers the bodywork 21 is not a question of cause. As for the power source, an electric motor can be used in place of the motor.
[0194] When referred to in relation to "direction" and "limb" in the present invention, the term "long" includes a case where the direction and limb are tilted within the range of ± 40 degrees. When referred to in relation to "direction" in the present invention, the term "extend" also includes a case where the direction is tilted within the range of ±40 degrees.
[0195] The upper middle axis M1 and the lower middle axis M4 may be referred to as a middle axis as a general term for this purpose. The upper transverse portion 51 and the lower transverse portion 52 may be referred to as a transverse portion as a general term for the same. The right side portion 54 and the left side portion 53 may be referred to as a side portion as a general term for the same.
[0196] In the invention, the linking mechanism 5 may further include a transverse portion in addition to the upper transverse portion 51 and the lower transverse portion 52. The upper transverse portion 51 and the lower transverse portion 52 are so called only because they are arranged relative to an upper position and a relatively lower position. The upper transverse portion 51 does not imply an upper transverse portion in the linking mechanism 5. The upper transverse portion may mean a transverse portion which is positioned lower than an upper transverse portion, but is positioned higher than a different transverse portion . The lower transverse portion 52 does not imply a lower transverse portion on the linkage mechanism. Lower cross portion may mean a cross portion that is positioned higher than a lower cross portion, but is positioned lower than a different cross portion. In addition, the transverse portion may include three parts, which are a piece of the part with a middle portion that is supported on the bodywork, a right portion that supports the right side portion and a left portion that supports the left side portion, and a pair of the right cross part and left cross part which are divided transversely. Thus, the upper transverse portion and the lower transverse portion may include a plurality of parts, as long as they still have a connecting function. The linking mechanism should only include the top portion and the bottom portion.
[0197] Furthermore, in the modality, while the lower transverse portion 52 is described as being made up of two parts that are the flat plate-shaped rear lower transverse portion 52a2 and the part that integrally includes the shaped front lower transverse portion of flat plate 52a1 and the connecting portions 52b that connect the portion 52a1 and the lower rear transverse portion 52a2 together. For example, by preparing the flat plate-shaped rear lower cross-section 52a2, the flat-plate-shaped front lower cross-section, and the two connecting portions 52b as four independent parts, the lower cross-section 52 can be constituted by one of these four parts.
[0198] When exercising the test forces, it is preferable that the test forces be exerted in a state such that the vehicle is fixed in the vertical state. The forward direction in relation to the direction of the upper right axle corresponds to a direction directed from the rear portion towards the front portion of the vehicle. The rear direction in relation to the direction of the upper right axle corresponds to a direction directed from the front portion to the rear portion of the vehicle. The top right axis, bottom right axis, top left axis, and bottom left axis are parallel to each other. Because of this, the forward direction relative to the upper right axis direction, the forward direction towards the lower right axis direction, the forward direction relative to the upper left axis, and the forward direction relative to the Lower left axis are the same in direction. Rear direction in relation to the upper right axis direction, rear direction in relation to the lower right axis direction, rear direction in relation to the upper left axis and rear direction in relation to the lower left axis are the same in direction.
[0199] Test forces can be exerted directly on the bearings. In addition, forces can be exerted directly to the lateral portion, so that test forces are eventually exerted on the bearings. The method exerting the test force is not limited to these methods, while a method allows the test forces to be exerted on the bearings. Test forces can be exerted on the bearings through the different portion of the side portion.
