The role of the rear arm of the car?
The longarm suspension system refers to the suspension structure in which the wheels swing in the longitudinal plane of the automobile, and it is divided into single longarm type and double longarm type. When the wheel jumps up and down, the single longarm suspension will make the kingpin rear Angle will have a large change, therefore, the single longarm suspension does not need to be on the steering wheel. The two swing arms of the double longarm suspension are generally made of equal length, forming a parallel four-bar structure. In this way, when the wheel jumps up and down, the rear Angle of the kingpin remains unchanged, so the double longarm suspension is mainly used in the steering wheel
