Universal profiling support device for tracked vehicle drive

Abstract

The invention is applicable to the technical field of tracked vehicles, and provides a universal profiling supporting device for crawler driving. The device comprises a plurality of rotary transmission parts, each rotary transmission part comprises a fixing base, a supporting wheel shaft and swing shafts distributed in a crossed mode, the supporting wheel shafts comprise the front supporting wheelshaft and the rear supporting wheel shaft, and the swing shafts comprise the front-back swing shaft and the left-right swing shaft; the fixing base is sleeved with the front-back swing shaft, a limiting space is formed below the fixing base, the left-right swing shaft is located in the limiting space, the two ends of the left-right swing shaft are sleeved with the front supporting wheel shaft andthe rear supporting wheel shaft respectively, and the two ends of the front-back swing shaft are in shaft connection with the supporting rods. Therefore, the device can adapt to different terrains, the crawler belt can be protected to the maximum extent, derailing is not prone to occurring, friction between the crawler belt and the walking wheels is reduced, and the service life of the crawler belt and the service life of the walking wheels are prolonged.

Description

technical field [0001] The invention relates to the technical field of crawler vehicles, in particular to a universal profiling supporting device for driving a crawler vehicle. Background technique [0002] The crawler traveling mechanism is widely used in field operation vehicles such as construction machinery and tractors. The running conditions are harsh, requiring the running mechanism to have sufficient strength and rigidity, and to have good traveling and steering capabilities. The track is in contact with the ground, and the drive wheels are not in contact with the ground. When the motor drives the drive wheel to rotate, under the action of the drive torque of the reducer, the drive wheel continuously rolls up the track from the rear through the mesh between the teeth on the drive wheel and the track chain. The part of the track that is grounded gives a backward force to the ground, and the ground correspondingly gives a forward reaction force to the track, and this...

AI Technical Summary

Problems solved by technology

In the prior art, the supporting rollers can generally swing in both directions. For more complex terrain, when there is a height difference in the left and right directions of the track during walking, the left and right directions of the track have no profiling effect, which will cause inconvenience to the track. Necessary wear and tear or even "derailment", thereby reducing the service life of the track and increasing maintenance and repair costs

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
