The main function of the suspension is to transmit

Suspension is the general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. The main function of the suspension is to transmit all forces and moments acting between the wheels and the body, such as supporting force, braking force and driving It also relieves the impact load transmitted to the vehicle body from uneven roads, attenuates the resulting vibration, ensures the comfort of the occupants, and reduces the dynamic load of the cargo and the vehicle itself. A typical automobile suspension structure is composed of elastic elements, shock absorbers, and guiding mechanisms. These three parts serve as buffers, damping, and force transmission. Most suspensions have coil springs and shock absorber structures, but the guiding mechanisms of different types of suspensions are very different, which is also the core component of the difference in suspension performance. According to different structures, it can be divided into non-independent suspension and independent suspension.
