The role of the suspension

The role of the suspension:

1. 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.

2. 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.

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

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