Background

The caterpillar chassis is mechanical engineering equipment and is mostly suitable for the small-sized light industry and the small-sized engineering machinery industry. The light industry is generally an agricultural machine with a weight of one ton to four tons, and the engineering machinery industry is mostly used in the small drilling industry. The crawler belt chassis is roughly divided into two kinds of rubber crawler belt chassis and steel crawler belt chassis according to crawler belt materials. The crawler chassis is widely used in environments with severe walking conditions, and is required to have sufficient strength and rigidity and good traveling and steering capabilities. The crawler belt is in contact with the ground, and the driving wheel is not in contact with the ground. When the motor drives the driving wheel to rotate, the driving wheel continuously rolls up the crawler belt from the rear through the meshing between the gear teeth on the driving wheel and the crawler belt chain under the action of the driving torque of the speed reducer. The ground engaging portion of the track applies a rearward force to the ground, which in turn applies a forward reaction force to the track, which is the driving force that urges the machine forward.

When the existing rubber crawler chassis is subjected to steering and other operations, the acting force between the crawler and the driving wheel is large, and the crawler can be separated from the driving wheel, so that derailment occurs, and the crawler is damaged or the continuous use of the crawler chassis is influenced.
