Further, the two elastic buffer portions 104 may be located at two sides of an axle of the vehicle, so that the mounting frame 102 of the track wheel device 100 may be buffered at two sides of the axle of the vehicle, uniformity of tensile force of the elastic buffer portions 104 is ensured, and stability of vehicle operation is further improved. In addition, the tension force can be ensured to be consistent when the vehicle runs in the forward direction and the reverse direction, and then the crawler wheel device 100 can be prevented from overturning in the forward direction and the reverse direction, so that the safety of the vehicle is ensured.

In any of the above embodiments, further, as shown in fig. 1 and 2, the track wheel device 100 further includes a driving wheel 128, the driving wheel 128 being configured to be connected to an axle of a vehicle; the driven wheels 130 are arranged on the mounting frame 102; the caterpillar 132 is sleeved outside the driving wheel 128 and the driven wheels 130.

In this embodiment, the track wheel device 100 includes a driving wheel 128, and the driving wheel 128 is disposed on the axle of the vehicle so as to be rotated by the axle of the vehicle. Further, the track wheel assembly 100 further includes a plurality of driven wheels 130 and a track 132. Wherein a plurality of driven wheels 130 are mounted to the mounting bracket 102 and are rotatable on the mounting bracket 102. The track 132 is sleeved on the driving wheel 128 and the plurality of driven wheels 130, in the driving process of the vehicle, the wheel shaft of the vehicle drives the driving wheel 128 to rotate, the driving wheel 128 drives the track 132 to move, and then the track 132 can drive the plurality of driven wheels 130 to rotate, so that the operation process of the track wheel device 100 is realized.

According to the utility model discloses a second aspect provides a vehicle, include: the crawler wheel apparatus 100 according to any one of the above aspects.

The utility model provides a vehicle, because of included any one of above-mentioned technical scheme's athey wheel device 100, consequently, this vehicle has included whole beneficial effect of above-mentioned athey wheel device 100, no longer gives unnecessary details here.

In particular, the vehicle may comprise an electrically assisted cart, a mining truck or a tractor.
