[0021] The locking mechanism includes a sway disc and a sway caliper 3. The sway discs are symmetrically arranged in two sets on the left front upper arm 6 and the right front upper arm 1. The sway caliper 3 is installed on the front suspension body. The sway discs and the sway caliper 3 work together to achieve locking.

[0022] The controller is mounted on the chassis; the yaw caliper 3 is electrically connected to the controller; the controller is used to control the clamping degree between the yaw disc and the yaw caliper by means of vehicle speed, wheel speed and engine speed.

[0023] Specifically, the controller determines the locking mode based on the vehicle speed and controls the clamping degree between the yaw disc and the yaw caliper 3 by using wheel speed and engine speed.

[0024] Locking is not allowed when the vehicle speed exceeds the preset value.

[0025] In this embodiment, the smaller the values ​​of wheel speed and engine speed, the greater the clamping force between the brake pads and the yaw disc.
