Pic. 14.1. Front suspension
Through it, the forces acting on the wheels are transmitted to the body. The suspension serves to reduce dynamic loads, reduce body vibrations, mitigate wheel impacts and road roughness, and ensure the stability and smoothness of the car.
Springs and shock absorbers connected together form McPherson shock absorbers, which are the main suspension element, combining the functions of a guide vane and a damping element.
The front wheel hub and ball bearing are installed with an interference fit in the steering knuckle. The splines of the drive shaft are inserted into the hub, the support of which it is (pic. 14.2).
Pic. 14.2. Drive shaft and front wheel hub
CV joints are used to reduce noise and vibration in the drive shaft (CV joints): on the hub side, RJ type, and on the gearbox side, TJ type.
Warning. It is strictly forbidden to carry out welding and straightening work on the suspension elements. Be sure to replace self-locking nuts, as well as bolts with traces of corrosion.
