    Drive and work vehicle with drive
    The present disclosure relates to drive bogie casters, and more particularly to rigidly mounted casters. 15
    It is common to provide drive rollers and bogies with suspension elements to absorb shocks and improve weight distribution, as shown for example in US Pat. No. 7,025,429 (see FIG. 6). This practice, when extended on rollers adjacent the drive sprocket, can result in damage and unavoidable wear on the drive sprocket. Further, under load conditions, the rear drive sprocket pulls on the chain to drive the track in a forward direction, pulling the chain taut and substantially eliminating the need for the roller closest to the drive sprocket to provide an expensive suspension. 25
    Disclosed herein is a drive that may include a rigidly mounted roller near or adjacent the rear drive sprocket. The remaining rolls and bogie can be suspended flexibly. By way of comparison, the rigidly mounted roller may, inter alia, improve vehicle weight distribution across the chain, reduce the number of parts in the drive, protect against entry of dirt into the toothed area of the drive sprocket, and increase ground or impact loads on the driveline to reduce.
    FIG. 1 is an illustration of a vehicle that can make use of the invention. FIG. 2 is a side view of a frame and a portion of FIG. 2. FIG
    Drive that makes use of the invention. Fig. 3 is a side view of a portion of the drive which is not twisted with respect to the frame. FIG. 4 is a side view of the portion of the drive of FIG. 3 rotated with respect to the frame. FIG. Fig. 5 is a side view of the drive and Fig. 6 is a side view of a prior art drive as disclosed in U.S. Patent 7,025,429.
    Fig. 1 is an illustration of a work vehicle in which the invention can be used. The bulldozer 10 shown includes a cab 20, a body 30, a main frame 40 and a track frame group 200.
    2 illustrates a side view of a portion of the crawler frame assembly 200 as well as a portion of the main frame 40 and a drive sprocket 50 rigidly mounted to the main frame 40 via a gearbox (not shown). As illustrated, the carriage 100 may include: a crawler frame assembly 200 having a first one or stationary section 200a and a second or moving section 200b; a chain tensioner bogie arm 210 pivotally attached to the moving portion 200b at a pivot point 211; a chain tensioner roller 215 rotatably attached to a first end 210a of the chain tensioner bogie arm 210 at 216; a first flexible pad 212 attached to a second end 210b of the chain tensioner bogie arm 210; a first small bogie 214 pivotally attached to the second end 210b of the chain tensioner bogie arm 210 on the pivot axis 213. Also shown is a first roller-Bugie arm 220 pivotally attached to a first end 220a on the stationary portion 200a on the rotary shaft 221; a second flexible pad 222 attached to a second end 220b of the first roller bogie arm 220; a second small bogie 224 pivotally attached to the second end 220b of the first scooter-bogie arm 220 on the pivot axis 223. The illustration further includes a second roller bogie arm 230 pivotally attached to a first end 230a of the stationary portion 200a on the rotary shaft 231; a third flexible pad 232 attached to a second end 230b of the second roller bogie arm 230; a third small bogie 234 pivotally attached to the second roller bogie arm 230 on the rotary shaft 233. At each of the small bogies 214, 224 and 234, conventionally, two rollers 217 can be mounted which rotate about their respective axes 218. The flexible pads or connectors 3 for i. ≫ 212, 222 and 232 may be made of an elastomeric material and may be conventionally attached to the chain tensioner bogie arm 210, the first and second roller bogie arms 220, 230 and the stationary portion as described. Stationary flexible pads 212 ', 222', 232 'may similarly be attached to the stationary portion 200a and positioned so as to maximize contact with their respective mating flexible pads 212, 222 and 232 as the second ends thereof move closer to stationary section 200a. In addition, the flexible pads 212 ', 222' and 232 'may also be made of an elastomeric material. As shown, a fixed roller 300 is rotatably attached to the crawler frame 200 on the rotation axis 301 of the fixed roller with the rotation axis 301 of the fixed roller being rigidly fixed with respect to the crawler frame 200. As shown in FIG. 5, the carriage 100 also includes a chain 101. It should be noted that only one track frame group 200 is shown in the figures, because the track frame 200 on the other side of the vehicle 10 15 is an identical reproduction of the illustrated track frame 200 can be.
    As shown in FIGS. 2, 3 and 4, the crawler frame 200 and the main frame 40 may be pivotally connected via a rotation shaft 201. As shown, a drive sprocket 50 may be rotatably connected to the main frame 40 via a driveline (not shown) and a conventional housing structure (not shown separately) and rotate about an axis 51 having a fixed position relative to the main frame 40. The crawler 200 may be slidably connected to a support beam (not shown). The support beam (not shown) may be pivotally connected pivotally to the main frame 40 at the center 25 between the track frames 200 and may adjust the angular range for the rotation of each track frame 200 about the rotation shaft 201 to a maximum angular range of e.g. Limit ± 3 °.
    When the vehicle is moving over irregular areas of the ground, the roller bogie arms 220, 230 and the chain tensioner bogie arm 210 may pivot about their respective axles 221, 231 and 211 according to the requirements of the terrain and weight of the vehicle 10 pivot. In addition, the attached rollers 217 rotate about their respective axes 218 and the short bogies 214, 224, 234 pivot about their respective axes 213, 223, 233, at 4
    To accommodate irregularities when the weight of the vehicle 10 causes the crawler 110 to flex and conform to the contours of the ground.
    As shown in FIG. 2, the fixed roller 300 can not bend with respect to the crawler frame 200 to accommodate the contours of the ground since it may have an axis 301 that is rigidly fixed with respect to the crawler frame 200. In addition, the fixed roller 300 may be located as close as practically possible to the drive sprocket 50. The proximity of the fixed roller 300 to the drive sprocket 50 may allow the fixed roller 300 to prevent a substantial amount of dirt from reaching the drive sprocket since the fixed roller will tend to crush and remove such dirt before it engages the drive sprocket 50 comes into contact. The fixed roller 300 may also reduce the amount of weight and impact load borne by the drive sprocket 50 because, due to its proximity to the drive sprocket 50, it may be capable of supporting a substantial portion of any load at that location.
    As shown in FIG. 2, an axis of the rotary shaft 201 and the drive sprocket rotation axis 51 may be arranged so as to be approximately equidistant from the ground, i. Y1 = Y2, Such an arrangement allows a minimum distance between the fixed roller 300 and the drive sprocket 50 and results in an improved weight distribution as described above.
    Fig. 4 illustrates the crawler frame in a maximum angular position of 3 ° with respect to the main frame, i. 3 ° in a direction representing the distance between an outer radius R1 of the fixed roller 300 and an outer radius R2 of the drive sprocket 50 (Note: FIGS. 2 and 3 show the crawler frame in an angular position of 0 ° with respect to the main frame Fig. 2 shows R1 and R2). In this exemplary embodiment of the invention, a minimum distance Xmin, as shown in FIG. 4, between R1 and R2 at the illustrated maximum angular position for non-interference between the fixed roller 300 and the drive sprocket 50 may be in the range of 3 to 6 cm. Thus, the crawler frame 200, the main frame 40, and the drive sprocket 50 may be constructed so that the distance between R1 and R2 is between 3 and 6 cm at the maximum angular position of 3 °. Such a construction may result in a minimum practicable distance between R1 and R2 at an angular position of 0 °.

    As described above and illustrated in FIG. 3, the rotational axis 301 of the fixed roller may move with respect to the rotational axis 51 of the drive sprocket whenever the track frame 200 rotates about the rotational shaft 201 with respect to the main frame 40. As described above, the rotational movement between the crawler frame 200 and the main frame 40 for this exemplary embodiment may be limited to a predetermined range of e.g. Be limited to ± 3 °. Thus, to place the fixed roller 300 as close as practically possible to the drive sprocket 50, the fixed roller 300 can be arranged to avoid interference with the movement of the drive sprocket 50 when the relative angle between the main frame 40 and the crawler frame 200 at its maximum (eg, 3 °) in a direction that reduces the distance between the fixed roller 300 and the drive sprocket 50. In this exemplary embodiment, the minimum practical distance Xmin between the outer radius R1 of the fixed roller 15,300 and the outer radius R2 of the drive sprocket 50 may be between 3 and 6
    Centimeters when the relative angle between the main frame 40 and the crawler 200 is at its maximum of 3 °. Thus, assuming that the relative angle between the crawler frame 200 and the main frame 40 is approximately 0 ° at angle C of FIG. 5, the minimum practical distance Xmm in FIG. 4 may be equal to (a2 + c2 - (2ac) x cos (B-30)) 14 - (R1 + R2). All indefinite angles and lengths can be determined using sine and / or cosine sets. It should be noted that the minimum practical spacing for configurations other than this exemplary embodiment may be greater in each area, which includes values greater than 0 cm at a maximum angle of any value greater or less than 0 °.
    Having described the preferred embodiment, it will be apparent that various modifications can be made without departing from the scope of the invention as defined in the appended claims. 30
