Definition

    The power steering pump is the power source of the hydraulic power steering system. It uses the engine as the transmission medium to convert mechanical energy into hydraulic energy. The steering gear converts the hydraulic energy into mechanical energy through the hydraulic oil output by the oil pump, thereby reducing the driver's operating intensity. Improve the maneuverability of the vehicle.

Working Principle

A system of several mechanisms working together, the power steering pump converts energy produced by a car's engine into hydraulic power, which it uses to add the torque to the movements of the steering wheel. 

Location

    The power steering pump is located near the pulley driven by the engine accessory belt, or under the steering wheel. The steering assist is mainly to assist the driver to adjust the direction of the car, and to reduce the strength of the driver to turn the steering wheel.
