It includes: wheel suspension, suspension, steering, brakes, wheel and tires. Wheel suspensions have the task of forming a connection between the vehicle body and the wheels. They must absorb high static forces (load) and dynamic forces (motive, braking and lateral forces). The function of the suspension: Due to the unevenness of a road surface, the wheels of a vehicle must perform movements up and down in addition to their rotation motion. When the vehicle is being driven fast, there movements occur within a very short space of time, generating accelerations and decelerations perpendicular to the road surface which are a multiple of acceleration due to gravity. This causes significant, impulsive forces to act on the vehicle, which are greater if the inertia is greater. The suspension works together with the damping to absorb jolts from the road and to convert them into vibrations. The main components of the chassis are frame, spring, shock absorbers, steering system, driving shaft，brakes，tires and wheels. On the whole, there are two suspensions of a car. 1. Front suspension: This system allows the front wheels
