Introduction of Electronic Hydraulic Power Steering System
Main components: oil storage tank, power steering control unit, electric pump, steering gear, power steering sensor, etc., wherein the power steering control unit and electric pump are a whole structure.
Working principle: The electro-hydraulic steering assist system overcomes the shortcomings of the traditional hydraulic steering assist system. The hydraulic pump used is no longer driven directly by the engine belt, but an electric pump. All the working conditions are calculated by the electronic control unit according to the driving speed and steering angle of the vehicle. 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 makes the driver save direction; when the car is driving at high speed, the hydraulic control unit drives the electronic hydraulic pump at a lower speed. Operation, while not affecting the need for high-speed steering, while saving part of the engine power.
