1, the power steering pump is the power source of the hydraulic power steering system, which through the engine as the transmission medium, the mechanical energy into hydraulic energy, the steering gear through the oil pump hydraulic oil can be converted into mechanical energy, which can reduce the driver's operation Strength, improve the role of vehicle maneuverability;
2, through the pressure relief valve control power steering pipe internal pressure to ensure that the steering system safety; 3, through the flow control valve to control the flow of steering system to ensure that the driver when driving high-speed steering
