Power steering pump unit:
1 - support for the electric pump unit of the power steering;
2 - electric motor;
a - signal connector;
b - power electrical connector.
The power steering pump unit delivers the required power based on information from the running engine.
The minimum speed of the power steering pump unit is 1000 rpm.
In order to optimize the applied force, depending on the engine and vehicle brand, various parameters of the power steering pump unit can be adjusted.
If the vehicle speed is 0 km/h, and the angular velocity of the steering wheel is zero, the force supplied by the electric pump unit is called «reserve effort». The power steering pump unit can supply different power depending on the following parameters:
- vehicle speed (as the speed of the car increases, the force decreases);
- speed of rotation of the power steering pump unit (with an increase in the angular speed of the steering wheel, the force increases);
- power steering LDS fluid temperature.
When the electric pump unit reaches a temperature of 125°C, it automatically switches off.
In the event of a malfunction of the electronic equipment, the electric pump unit uses the emergency parameters and goes into emergency mode.
