The selection of its homework environment is roughly as follows:

(1) The operating temperature of rubber tracks is generally between -25~+55'C.

(2) The salt content in engine oil and seawater can cause aging of the tracks, so it is necessary to clean the tracks after use in such environments.

(3) A road surface with sharp protrusions (such as steel bars, stones, etc.) can cause damage to rubber tracks.

The track in this utility model forms a triangular track wheel body through driving wheels, guiding wheels, and supporting wheels. The supporting wheels are used to support walking. Due to the use of the triangular wheel body, the contact area between the entire track wheel and the ground is reduced, making it easy to cross potholes. At the same time, the use of the triangular track wheel chassis can increase the height of the chassis, making it convenient to cross potholes.
