Drive shafts (Opel Vectra B)

In order to avoid jerks in the steering when driving and controlling the car, the drive shaft joints must transmit the force flow exactly the same in all positions of the shock absorbers and steering. This requirement is met by so-called homokinetic joints (constant velocity joints). Their function is based on the reciprocating motion of six balls along specially ground guides when the hinge bends. Thus, at any possible angle of inclination of the drive shaft, uniform transmission of force is ensured. The differential has a so-called movable hinge. It provides the necessary linear compensation, but can withstand only a slight angle of inclination. A rigid hinge is located on the wheel. Here, there is no need for linear compensation, but for a large angle of inclination when turning the steering wheel.
