The suspension is an important part connecting the chassis and the frame. The supporting force, braking force, and driving force of the vehicle are all transmitted through the suspension system, and it can also reduce the impact of bad roads on the vehicle and ensure the stability of the vehicle. ,

The vehicle suspension system is an important part used to connect the frame and the axle, and generally consists of shock absorbers, elastic elements, and guide mechanisms. When the vehicle is running, the ground and the vehicle generate a corresponding force. If this force is directly transmitted

Classification of semi-trailer suspensionSuspension is a general term for all force-transmitting connection devices between the semi-trailer frame and the axle, which is used to transmit the force and torsion acting between the wheels and the frame, and buffer the impact force transmitted from the r
