Overview

To reduce the force applied to the steering wheel to rotate it, set cars on hydraulic power steering. As additional force is used under high pressure fluid that is supplied to the working cylinders arranged on the steering mechanism. Distribution valve serves for injection in the power cylinder pressurized fluid which corresponds to the angle of the steering wheel. The control valves operate in accordance with the principle of so-called open-center, ie, when the control valve does not operate, the liquid delivered by the pump, is bypassed back to the tank at zero pressure. The hydraulic pressure created by a pump driven by a belt from a crankshaft pulley.

The steering mechanism is connected to the steering shaft via an intermediate shaft.

The elements of active safety models Passat, no doubt, true power steering. The steering must be easy and immediately respond to the rotation of the steering wheel. Steering linkage and actuators must be optimally designed and connected. Like most modern models, Passat is equipped with a maintenance-free rack and pinion power steering.
