    RUNNING GEAR FOR TRACKED VEHICLE, TRACKED VEHICLE INCORPORATING SUCH A ROLLING BEARING AND METHOD FOR CONVERTING A WHEEL VEHICLE INTO TRACKED VEHICLE.
    FR 3 058 702 - A1
    The subject of the invention is an undercarriage for a tracked vehicle, intended to connect a track (3) to a vehicle (1). This undercarriage (9) is characterized in that it comprises a wheel (10) which is intended to come into contact with the track (3) at the level of a lower strand (3a), a wheel which is integral with a plate (11) intended to be fixed to a suspension system of the vehicle so as to move substantially vertically relative to the body (2) of the vehicle, the plate (11) also carrying at least one roller (17) fixed at the end of a pivoting arm (18), a roller intended to be kept in contact with the track (3) by a pushing means (20).
    The invention also relates to a vehicle incorporating such a running gear and a conversion method.
    from a wheeled vehicle to a tracked vehicle.
    The technical field of the invention is that of tracked vehicles and more particularly running gear for tracked vehicles.
    Tracked vehicles are classic in both the armaments and civil fields.
    A tracked vehicle most often comprises a body which is connected to the ground at each lateral side of the body by at least one undercarriage comprising a track.
    Each track is connected to propulsion means, such as a heat engine, by drive means which generally include a mechanical movement down system connected to drive wheels (or sprockets) by at least one drive shaft. .
    In addition, a differential speed steering system is also interposed between the drive shaft and the sprockets.
    Gypsies are cogwheels which mesh on complementary teeth carried by the links of the caterpillar. The tracked undercarriage also includes a deflection wheel which generally makes it possible to adjust the tension of the track and of the track rollers which are supported on the track strand in contact with the ground.
    Upper support rollers are supported on the free track strand and they make it possible to limit the movements and vibrations of the track.
    On known vehicles and undercarriages, the rollers are connected to the vehicle body by a suspension means comprising for example an articulated arm subjected to the action of a return spring.
    Such undercarriage has insufficient track guiding performance. There are many rollers to support the mass of the vehicle. It is generally necessary to group them into bogies which pivot relative to an axis carried by the articulated arm. The suspension spring is not then sufficient to maintain all the rollers, only a part of which exerts effective support on the track.
    This may result in the risk of weeding. It also results in a loss of the driving energy supplied to the gypsy.
    The object of the invention is to propose an undercarriage architecture for a tracked vehicle in which the connection between the body and the track is optimal with permanent contact of the rollers during running.
    Thus the undercarriage according to the invention makes it possible to design a vehicle combining the handling characteristics of a wheeled vehicle with the mobility qualities in difficult terrain of a tracked vehicle.
    Thus, the subject of the invention is an undercarriage for a tracked vehicle, intended to connect a track to a vehicle, undercarriage characterized in that it comprises a wheel which is intended to come into contact with the track at a lower strand, a wheel which is integral with a plate intended to be fixed to a vehicle suspension system so as to move substantially vertically relative to the vehicle body, the plate also carrying at least one roller fixed to the end of a pivoting arm, roller intended to be kept in contact with the track by a pushing means.
    According to one embodiment, the wheel may include indentations intended to cooperate with complementary profiles carried by the track.
    According to one embodiment, the thrust means may have a variable length and will constitute a spring means intended to ensure the maintenance of the roller bearing against the track.
    According to another embodiment, the pushing means will have an adjustable length, the roller being intended to form part of a means of tensioning the track.
    The invention also relates to a vehicle incorporating at least one such undercarriage.
    The subject of the invention is therefore a tracked vehicle comprising a body which is connected to the ground at each lateral side of the body by at least one track, each track being connected to propulsion means by drive means, vehicle which is characterized in that the track is connected to the vehicle by at least one undercarriage according to the invention, the plate of each undercarriage being secured to the vehicle by means of a suspension system and being able to move substantially vertically with respect to the vehicle body.
    According to one embodiment, at least one undercarriage will have its wheel coupled to the drive means, the wheel then constituting a drive wheel capable of cooperating with the track to drive the latter.
    According to one embodiment, all the wheels of the different undercarriages can be coupled to the drive means.
    According to another embodiment, only the wheel of the undercarriage located furthest from the vehicle in the direction of advance of the latter will be coupled to the drive means.
    Advantageously, for at least one undercarriage, the roller will be disposed in front of the wheel in the direction of advance of the vehicle.
    According to one embodiment, the undercarriage located furthest forward of the vehicle in the direction of advance of the latter carries a roller which is connected to the plate by a pushing means with adjustable length, the roller then forming a part a means of tensioning the track.
    According to one embodiment, the undercarriages located behind the undercarriage located furthest forward of the vehicle in the direction of advance of the latter carry a roller which is connected to the plate by a variable length pushing means which is a spring means ensuring the maintenance of the roller bearing against the track.
    The invention also relates to a method for converting a vehicle comprising at least two wheels on each lateral side of a body into a tracked vehicle.
    Thus the subject of the invention is a method of converting a vehicle comprising at least two wheels on each lateral side of a body into a tracked vehicle, method in which a running gear is fixed in place of each wheel the invention, at least one track being then placed on each side of the vehicle, the wheels of the undercarriages being in contact with the track at a lower strand and each roller being kept in contact with the track by means of thrust, the track being able to be driven by at least one wheel of one of the undercarriages which is coupled to the means of propulsion of the vehicle by drive means.
    According to one embodiment, a single track may be provided on each side of the vehicle.
    The invention will be better understood on reading the description which follows, description made with reference to the appended drawings and in which:
    - Figure 1 is a schematic rear view of a vehicle according to an embodiment of the invention, the tracks being shown cut at the rear wheels;
    - Figure 2 is a schematic side view of the same vehicle;
    - Figure 3 is a side view of a running gear according to the invention;
    - Figures 4a and 4b are three perspective views of this undercarriage, Figure 4a being a view of three front quarter from a point of view external to the vehicle, Figure 4b being a view of three rear quarter to from an internal point of view in the vehicle;
    - Figure 5 is a view of a particular running gear having a traction function;
    - Figure 6 is a side view of an undercarriage having a track tensioner function.
    Referring to Figures 1 and 2, a tracked vehicle 1 according to the invention comprises a body 2 which is connected to the ground at each lateral side of the body by at least one track 3. This vehicle here comprises two tracks 3 which extend over substantially the entire length of the vehicle. Each track 3 is connected to propulsion means 4 (such as a powertrain) by drive means which here comprise: a movement descent 5, a main drive shaft 6, a speed differential steering device 7 and lateral shafts 8a and 8b which connect the steering device 7 to two lateral undercarriages 9 according to the invention, one per track.
    The drive means are conventional mechanical members and it is not necessary to describe them in detail. A movement descent 5 is a mechanical member comprising gears and making it possible to transmit the rotary movement provided by the powertrain 4 to a transmission shaft 6 which is arranged at a distance from the output shaft of the group 4 and parallel to it. this.
    The steering device 7 is also a conventional member. For example, the patents FR2446756 and
    US3373636 describe such a device. The lateral shafts 8a and 8b are connected to the lateral undercarriages 9 by universal joints (not shown) in order to be able to follow the vertical movements of the latter. Mechanical reduction boxes may also be interposed between the powertrain 4 and the steering device 7 or between the steering device 7 and the side undercarriages 9. This in order to adapt rotation speed and torque as required .
    Each track 3 is therefore connected to the vehicle 1 by at least one undercarriage 9 according to the invention.
    It can be seen in FIG. 2 that the vehicle here has four undercarriages 9 at each track 3.
    Figures 3 and 4a, 4b show more precisely the structure of a running gear 9 according to the invention.
    Each undercarriage 9 comprises a wheel 10 which is in contact with the track 3 at the level of the lower strand 3a thereof (FIG. 2).
    This wheel 10 is integral with a plate 11 with respect to which it is free to rotate. The plate 11 can move substantially vertically relative to the body 2 of the vehicle by means of a suspension system
    12.
    There is shown diagrammatically in FIG. 1 a suspension system 12 with a deformable parallelogram which comprises a lower arm 13 (or lower triangle) and an upper arm 14 (or upper triangle). These arms are also visible in Figures 4a and 4b. They are articulated relative to the plate 11 at the axes 13a and 14a which are parallel to a direction of longitudinal advance 15 of the vehicle 1 (Figure 2).
    As can be seen in FIG. 1, the arms 13 and 14 are also articulated relative to the body 2 of the vehicle at the axes 13b and 14b which are parallel to the axes 13a and
    14a. The suspension 12 thus produced is known as a suspension with a deformable parallelogram or with a double triangulation. It is classic in the field of vehicles. It is completed by a shock absorber 16 which is mounted between the body 2 and one of the arms 13 or 14.
    Such a suspension makes it possible to ensure, during the advance of the vehicle, a vertical movement of the plate 11 relative to the body 2 of the vehicle. The ground resistance is excellent and the wheel 10 is always held in abutment against the lower strand 3a of the track.
    As seen in Figures 3, 4a and 4b, the plate 11 also carries a roller 17 which is fixed to the end of an arm 18 which is pivotally mounted relative to the plate 11 (see Figure 3) . The roller 17 is free to rotate relative to the arm 18. The arm 18 is pivotally mounted on the plate 11 at a pivot axis 19 (Figure 3).
    A variable length pushing means 20, such as a gas spring or a jack, is mounted between the plate 11 and the arm 18. The pushing means 20 is fixed to the plate 11 by a first articulation 20a and to the arm 18 by a second articulation 20b (FIG. 4b).
    The thrust means 20 maintains the roller 17 in contact with the track 3 during the rolling phases.
    With such an arrangement, it is ensured that the wheel 10 and the roller 17 are always in contact with the lower strand 3a of the track. Even if the wheel 10 lifts with its plate 11, the thrust means 20 keeps the roller 17 against the track. Furthermore, the suspension 12 also pushes the wheel 10 towards the track 3. The assembly thus accompanies the movements of the vehicle, even on uneven ground, without loss of contact. The guiding of the track is therefore optimal and the risks of weeding are limited.
    As can also be seen in the figures, the plate 11 carries an upper support roller 21 which makes it possible to limit the movements and vibrations of the upper track strand 3b.
    This upper roller 21 is free to rotate relative to the plate 11 but it has a fixed position relative to the latter. The vertical movements of the undercarriage 9 which are allowed by the suspension 12 will therefore cause both the displacement of the lower strand 3a and of the upper strand 3b of the track. The undercarriage 9 thus delimits two equidistant running surfaces receiving the strands 3a and 3b of the track 3.
    As seen in Figure 2, each roller 17 is disposed in front of the wheel 10 to which it is connected, the forward position is of course identified with respect to the normal direction of advance of the vehicle, forward AV of the last. The AR mark locates the rear of the vehicle. Such an arrangement also improves the contact of the undercarriage 9 with the track 3. The roller 17 is applied against the lower strand 3a of the track and it also applies this strand to the ground before the passage of the wheel 10, which facilitates the cooperation of the wheel 10 with the raceway of the lower strand 3a.
    In a conventional manner and shown in the figures, the wheel 10 like the roller 17 and the upper roller 21 may include a central groove (marked respectively 10a, 17a and 21a in the figures) which cooperates with the teeth 3c of the track ( figure 1) . The teeth 3c are guided by the grooves 10a, 17a and 21a. The track 3 is thus held laterally relative to the undercarriage 9.
    The wheels 10 and the rollers 17 and 21 conventionally carry a rubber tire in order to limit noise and wear.
    FIG. 5 shows the undercarriage 9 located furthest back. This train 9 differs from the previous one only in the shape of the wheel 10 which has indentations
    22a and 22b on either side of the middle groove 10a. These indentations are intended to cooperate with complementary profiles (not shown) carried by the track 3.
    This rear wheel 10 here constitutes a drive wheel which is coupled to the drive means 8a, 8b. It is this drive wheel which engages in the track 3 and causes the mobility of the vehicle.
    In the example shown in Figure 2, only the wheel of the undercarriage 9 located furthest rear of the vehicle in the direction of advance of the latter is coupled to the drive means. The wheels 10 of the other undercarriages 9 are free to rotate.
    Figure 6 shows the undercarriage 9 located most forward AV of the vehicle in the direction of advance of the latter. This train 9 differs from the others only in the nature of the thrust means 20 which carries the roller 17. This thrust means is not here constituted by a spring whose length will vary constantly during rolling but by a jack 20 ( electric or hydraulic), with a fixed but adjustable length, which makes it possible to fix the position of the roller 17 relative to the plate 11. The jack 20 could be a dynamic compensation jack, ie a jack whose length is continuously controlled during driving by a control unit. Such dynamic compensation cylinders are known for continuously adjusting the tension of a track. We can for example consult the patents FR2703971 or US4840437.
    The jack 20 and the roller 17 then form, for this undercarriage 9, a means of tensioning the track 3.
    The length 20 can be adjusted manually during vehicle maintenance phases. It can also be adjusted during driving by the driver of the vehicle and using an appropriate control device.
    There is shown a vehicle in which only the rearmost undercarriage 9 was coupled to the drive means.
    It is possible, as a variant, to couple to the drive means more than one wheel 10 per track (or even all the wheels 10 of the different undercarriages 9).
    This coupling will be carried out using differential transfer boxes of the conventional type similar to those used in vehicles comprising several sets of drive wheels.
    The only difference here is that the vehicle wheel is replaced by the wheel of a running gear 9 driving the track.
    When each track is thus driven by several drive wheels, there is an improvement in the efficiency of the drive, in particular when advancing on a slope. This improvement in traction efficiency is on the order of one percent for eight-wheel drive versus two-wheel drive.
    When the drive is provided by several drive wheels for each track, it is possible to make all the drive wheels in the form of FIG. 5, that is to say with indentations which can cooperate with complementary profiles carried by the track.
    It has been noted that the invention makes it possible to combine the advantages of traction by a track (all-terrain efficiency) with those of traction by wheels (effective suspension).
    The invention also provides a method for converting a vehicle comprising at least two wheels on each lateral side of a body into a tracked vehicle.
    Wheeled vehicles, in particular armored vehicles, comprising several traction axles are conventional. Each wheel of such a vehicle is suspended relative to the vehicle body by a deformable parallelogram suspension.
    With the method according to the invention, a running gear 9 according to the invention and as described above and in particular comprising a wheel 10 which is secured to a plate 11. The plate will be fixed in place of each wheel. 11 will then be fixed to the suspension 12 of the vehicle in place of the wheel of the initial vehicle. We can then connect the wheel 10 to the propulsion means of the vehicle by drive means which may be those which already drove the wheels of the initial vehicle.
    There is then at least one track 3 on each side of the vehicle so as to be driven by at least one wheel 10 of one of the undercarriages 9 thus put in place.
    The assembly is then identical to that shown in Figures 1 and 2. The wheels 10 of the undercarriages 9 are in contact with the track 3 at a lower strand 3a. The wheels 10 can moreover move substantially vertically relative to the body of the vehicle by means of the suspension system 12.
    Of course the plate 11 also carries at least one roller 17 fixed to the end of an arm 18 which is pivotally mounted relative to the plate 11. The roller 17 is kept in contact with the track by a pushing means
    20.
    Thus, it is easy to go from a wheeled vehicle to a tracked vehicle while retaining the drive means of the wheeled vehicle which are then used for driving the tracks.
    A single track may be provided on each side of the vehicle. As a variant, it is possible to provide several tracks on each side of the vehicle for example, according to the example in FIG. 2, two tracks can be provided on each side: a front track coupling the two front undercarriages 9 and a rear track coupling the two rear undercarriages. Of course, each track is driven by its own traction wheel, for example the wheel 10 of the rear axle of the considered track.
    As previously specified, all the wheels 10 of the undercarriages 9 can be driven.
