Main components

Oil storage tank, power steering control unit, electric pump, steering gear, power steering sensor, etc., in which the power steering control unit and the electric pump are an integral structure.

working principle

The electronic hydraulic power steering system overcomes the shortcomings of the traditional hydraulic power steering system. The hydraulic pump it uses is no longer driven directly by the engine belt, but an electric pump. All of its working states are calculated by the electronic control unit according to the vehicle's driving speed, steering angle and other signals. Simply put, at low speed and large steering, the electronic control unit drives the electronic hydraulic pump to output high power at high speed, which saves the driver's direction. Operation, while not affecting the need for high-speed steering, save a part of engine power.
