Crawler walking mechanisms are widely used in construction machinery, tractors, and other field operation vehicles. The operating conditions are harsh, requiring the walking mechanism to have sufficient strength and rigidity, as well as good maneuverability and steering capability. The crawler travel device includes a "four-wheel drive" (drive wheel, load-bearing wheel, guide wheel, carrier roller, and track), a tensioning device, and a buffer spring. This walking mechanism is a chassis model of a tracked vehicle that can be opened with Solidworks. You are welcome to download it.
