Automobile chassis suspension system

The role of the suspension

a. The vertical reaction force (supporting force), longitudinal reaction force (traction force and braking force) acting on the road surface, and the moment caused by these reaction forces are all transmitted to the frame (or load-bearing body) to ensure that the vehicle Drive normally.

b. In the case of load changes, vehicle speed turning, etc., it is necessary to keep the wheels and the axis properly matched to ensure the stability of the vehicle.

c. Ensure the operability of the vehicle's driving direction, and ensure that the driver can effectively control the steering under various road conditions.

d. Work together with the tires to buffer the vibration from the wheels, so that the vehicle can run comfortably and smoothly.

Auto Suspension

Suspension Category

Car suspension can be divided into two categories: non-independent suspension and independent suspension

As shown in the figure below. The structural feature of the non-independent suspension is that the wheels on both sides are connected by an integral axle. The wheels, together with the axles, are connected to the frame through elastic suspensions. When one side of the wheel jumps due to uneven roads, it will inevitably cause the other side of the wheel to swing in the transverse plane of the car. 

Non-independent Suspension

The structural feature of the independent suspension is that the axles are disconnected, and the wheels on each side can independently dance with the wheels on both sides of the frame through the elastic suspension without affecting each other.
