[0002] The track is driven by the driving wheel and is a flexible chain link surrounding the driving wheel, road wheel, inducer wheel and track roller. The track is composed of track shoes and track pins. The track pins connect the track shoes to form track chain links. There are holes at both ends of the track shoes, which engage with the driving wheel. There is an inducer tooth in the middle to straighten the track and prevent the track from falling off when the tank turns or tilts. The track assembly is the general term for the moving part that can constitute the track.

[0003] The current crawler track assembly usually uses the driving wheel to drive the track plate to rotate to achieve walking. Since the bottom end of the track plate is set parallel, the contact area with the ground is large. Therefore, when walking on uneven bottom surfaces, the shock absorption and tensioning effects of the crawler are limited, which can easily cause the crawler walking machine to be unstable, affect the passing quality of the crawler, and lead to poor walking comfort of the crawler.
