Introduction to multi-link suspension

Multi-link suspension is a suspension in which (3-5) rods are combined to control the position of the wheels. The multi-link type can make the wheel swing around an axis that is at two fixed angles to the longitudinal axis of the car. It is a compromise between the transverse arm type and the trailing arm type. The angle between the swing arm axis and the longitudinal axis of the car is appropriately selected. The advantages of transverse arm and trailing arm suspension can be obtained to different degrees, and can meet different performance requirements. The main advantage of the multi-link suspension is that the track and toe change little when the wheels are beating, and the car can steer smoothly according to the driver's intention regardless of whether the car is driving or braking. The disadvantage is that the car Shaft swing phenomenon occurs at high speed.
