When the vehicle is traveling on a relatively complex mountain road, the connection of the steering knuckle arm will not only be affected by friction, but also by vibration. Although it is mentioned that the shock absorber rod is installed on the front axle, the installation position and shock absorption effect are not described in detail. In addition, the vehicle is bumpy for a long time, and friction occurs continuously at the connection of the shock absorption system. The heat generated will also affect the protection of the shock absorption system to the steering knuckle arm. Utility Model Content
