An all-terrain tracked vehicle chassis

Abstract

This utility model discloses an all-terrain tracked vehicle chassis, including a mounting frame and a traveling mechanism disposed on both sides of the mounting frame. The tracked vehicle body is mounted in the middle of the mounting frame. The traveling mechanism includes a drive wheel, a tension wheel, multiple support rollers, and tracks. The tension wheel is adjustablely mounted on the mounting frame. Each support roller is independently mounted on the mounting frame. The tracks are fitted onto the drive wheel, tension wheel, and support rollers, and the tracks rotate in conjunction with the drive wheel. This utility model uses independently mounted support rollers, so damage to a single roller will not affect vehicle operation; only the damaged roller needs to be repaired or replaced, without replacing the entire vehicle. Furthermore, the adjustable tension wheel allows for adjustment of track tension to adapt to different terrains and prevent slippage or track detachment.

Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, specifically relating to an all-terrain tracked vehicle chassis. Background Technology

[0002] Tracked vehicles, with their excellent terrain adaptability, are commonly used in all-terrain scenarios such as field operations and engineering transportation. The tracked chassis, as a key driving and load-bearing component of tracked vehicles, directly affects the vehicle's performance. Currently, traditional tracked vehicle chassis mostly adopt an integrated structure, which has significant shortcomings in practical applications.

[0003] On the one hand, the integration of track rollers and track systems in traditional chassis is high. When a single track roller is damaged, the entire track must be completely removed from the chassis before the damaged track roller can be replaced. The maintenance operation is cumbersome and time-consuming, which seriously affects the normal use of the vehicle. On the other hand, most traditional tracked vehicle chassis are not equipped with tension rollers or the position of the tension rollers cannot be adjusted, which makes the tracks prone to being in a loose state during driving. This not only makes it easy to slip on soft ground, but also causes the tracks to frequently fall off, greatly reducing the chassis's all-terrain passability. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide an all-terrain tracked vehicle chassis that solves the problems of inconvenient maintenance, easy slippage, and track detachment in existing tracked vehicle chassis.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An all-terrain tracked vehicle chassis is installed and fitted with a tracked vehicle body. The all-terrain tracked vehicle chassis includes a mounting frame and a running gear disposed on both sides of the mounting frame. The tracked vehicle body is mounted in the middle of the mounting frame. The running gear includes a drive wheel, a tension wheel, multiple support rollers, and a track. The tension wheel is mounted on the mounting frame in an adjustable position. The multiple support rollers are each independently mounted on the mounting frame. The track is fitted onto the drive wheel, tension wheel, and support rollers, and the track drives the drive wheel to rotate through cooperation with the drive wheel.

[0007] With the above structural design, multiple track rollers are installed independently. When a single track roller is damaged, it will not affect the vehicle's operation. Only the damaged track roller needs to be repaired or replaced, without the need to replace the entire vehicle. At the same time, by setting an adjustable tensioning roller, the track tension can be adjusted to adapt to different terrains and prevent slippage or track detachment.

[0008] As a further improvement, the walking mechanism also includes a drive motor, which is mounted on the mounting bracket and driven by the drive wheel.

[0009] As a further improvement, the drive wheel is provided with uniform drive teeth, and the track is provided with corresponding through holes. The drive wheel drives the track to rotate through the cooperation of the drive teeth and the through holes.

[0010] The above structural design facilitates the rotation of the tracks via the drive wheel, and the transmission structure is simple and has high transmission efficiency.

[0011] As a further improvement, the tensioning wheel is adjustablely mounted on the mounting bracket via an adjustment mechanism;

[0012] The adjustment mechanism includes a mounting frame and a movable rod movably mounted on the mounting frame. One end of the movable rod is connected to a tension wheel, and the other end is provided with a connecting plate. An adjustment screw is provided between the connecting plate and the mounting frame, and an adjustment nut is provided at the free end of the adjustment screw.

[0013] With the above structural design, the adjustment mechanism adjusts the front and rear positions of the tensioning wheel by adjusting the adjusting nut, which is convenient and does not require much manpower.

[0014] As a further improvement, the track roller is fitted with the inner side of the lower end of the track, and a shock absorber is provided on the track roller.

[0015] As a further improvement, the support roller is provided with a rotating shaft in the middle, and the support roller is mounted on the rotating shaft through a bearing. One end of the rotating shaft is fixedly connected to a connecting rod, and the other end of the connecting rod is movably mounted on a mounting bracket. One end of the shock absorber is rotatably connected to the connecting rod, and the other end is rotatably connected to the mounting bracket.

[0016] With the above structural design, the shock absorber can adaptively adjust the position of the support roller when passing through uneven terrain, thereby improving the vehicle's passability.

[0017] As a further improvement, the track roller is provided with a movable groove in the middle, and a limiting block is provided in the middle of the inner side of the track, with the limiting block located in the movable groove.

[0018] As a further improvement, the walking mechanism also includes a support roller, which is mounted on the mounting bracket and located inside the track to support the track above.

[0019] As a further improvement, the walking mechanisms on both sides of the mounting frame are symmetrically arranged.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, multiple support rollers are installed independently. When a single one is damaged, it will not affect the vehicle's operation. Only the damaged support roller needs to be repaired or replaced, without replacing the entire vehicle. At the same time, by setting an adjustable tension roller, the tension of the track can be adjusted to adapt to different terrains and prevent slippage or track detachment.

[0022] 2. The adjustment mechanism of this utility model adjusts the tension of the track by adjusting the position of the tensioning wheel by adjusting the screw nut in or out. The adjustment method is simple and labor-saving.

[0023] 3. Each support roller of this utility model is equipped with a shock absorber. When passing through different terrains, the position of the support roller can be adjusted by the buffering characteristics of the shock absorber, thereby further improving the vehicle's passability.

[0037] Please see Figures 1 to 8 An all-terrain tracked vehicle chassis is disclosed, which is installed and fitted with a tracked vehicle body 100. The all-terrain tracked vehicle chassis includes a mounting bracket 1 and a traveling mechanism 2 disposed on both sides of the mounting bracket 1. The tracked vehicle body 100 is mounted in the middle of the mounting bracket 1. The traveling mechanism 2 includes a drive wheel 2a, a tension wheel 2b, multiple support rollers 2c, and a track 2d. The tension wheel 2b is adjustablely mounted on the mounting bracket 1, and the multiple support rollers 2c are each independently mounted on the mounting bracket 1. The track 2d is fitted onto the drive wheel 2a, the tension wheel 2b, and the support rollers 2c, and the track 2d rotates by cooperating with the drive wheel 2a.

[0038] Please continue reading. Figures 1 to 4The traveling mechanism 2 further includes a support roller 2i and a drive motor 2m. The support roller 2i is mounted on the mounting frame 1 and located inside the track 2d, supporting the track 2d. The drive motor 2m is mounted on the mounting frame 1 and is driven by the drive wheel 2a. The drive wheel 2a has evenly spaced drive teeth 21a, and the track 2d has corresponding through holes 21d. The drive wheel 2a drives the track 2d to rotate through the engagement of the drive teeth 21a and the through holes 21d. The engagement method between the drive wheel 2a and the track 2d is prior art and will not be described in detail here.

[0039] Please see Figure 3 and Figure 5 Furthermore, the tensioning wheel 2b is adjustablely mounted on the mounting frame 1 via the adjusting mechanism 2n. The adjusting mechanism 2n includes a mounting frame 21n and a movable rod 22n movably mounted on the mounting frame 21n. One end of the movable rod 22n is connected to the tensioning wheel 2b, and the other end is provided with a connecting plate 23n. An adjusting screw 24n is provided between the connecting plate 23n and the mounting frame 21n, and an adjusting nut 25n is provided at the free end of the adjusting screw 24n.

[0040] Please see Figures 6 to 8 The support roller 2c mates with the inner side of the lower end of the track 2d, and a shock absorber 2e is provided on the support roller 2c. A rotating shaft 2f is located in the middle of the support roller 2c, and the support roller 2c is mounted on the rotating shaft 2f via a bearing 2j. One end of the rotating shaft 2f is fixedly connected to a connecting rod 2g, and the other end of the connecting rod 2g is movably mounted on a mounting bracket 1. One end of the shock absorber 2e is rotatably connected to the connecting rod 2g, and the other end is rotatably connected to the mounting bracket 1.

[0041] In this embodiment, the walking mechanisms 2 on both sides of the mounting frame 1 are symmetrically arranged, that is, each side is equipped with a drive motor 2m, which can drive the walking mechanisms 2 on both sides independently. When one side of the walking mechanism 2 is working, the other side of the walking mechanism 2 stops working, which can achieve turning with a small turning radius; when one side of the drive motor 2m rotates in the forward direction, the other side of the drive motor 2m rotates in the reverse direction, which can achieve turning around on the spot. The drive motor 2m can rotate in either the forward or reverse direction. In this embodiment, each side of the walking mechanism 2 is equipped with 4 sets of support rollers 2c.

[0042] The working principle of this utility model is as follows:

[0043] The multiple support rollers 2c in this invention are independently installed and each is equipped with a shock absorber 2e. This not only improves the passability on different road conditions, but also ensures that the vehicle's operation is not affected even if a single support roller 2c is damaged, and allows for individual replacement or repair. Furthermore, when it is necessary to adjust the position of the tension roller 2b to adjust the tension of the track 2d, the adjusting nut 25n can be manually rotated, thereby moving the connecting plate 23n and the movable rod 22n forward or backward, thus achieving the position adjustment of the tension roller 2b.

[0044] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
