GF46.50-P-0001CW Speed-Sensitive Power Steering (SPS), Function

GF46.50-P-0001CW Speed-sensitive power steering (SPS), function
- with CODE (213) Speed-sensative power steering

Component Identification:

The steering wheel's rotary motion is converted into horizontal movement through the steering gear rack-and-pinion steering.

The rack-and-pinion steering gear has a constant gear ratio, i.e. the tooth pitch is identical across the entire toothed rack.

Steering assistance is executed hydraulically by a belt driven power steering pump.

To cool the power steering fluid an oil cooler in the form of a coiled pipe is installed immediately upstream of the A/C system's condenser. The oil cooler version depends on the engine mounted in each particular vehicle.

The steering assistance is regulated by the rack-and-pinion steering gear itself. The manual effort required to turn the steering wheel is increased from vehicle standstill up to a speed of v = 100 km/h in accordance with a given characteristic.

The hydraulic reaction assembly is adapted to match requirements via the speed-sensitive power steering solenoid valve. The electronic control is provided by the Electronic Stability Program control unit (N30/4).
