Power steering pump
1. The power steering pump is the power source of the hydraulic power steering system. It converts the mechanical energy into hydraulic energy through the engine as the transmission medium.
2. Control the internal pressure of the power steering pipeline through the pressure relief valve to ensure the safety of the steering system;
3. Control the flow of the steering system through the flow control valve to ensure the driver's steering feel when driving at high speed.
Classification of power steering pumps
1. It can be divided into: steering pump for commercial vehicles and steering pump for passenger vehicles.
2, from the structure, can be divided into: vane steering pump, gear steering pump, plunger steering pump; Among them, the double-acting vane steering pump is widely used in various models due to its advantages of small size, low noise and high volume efficiency.
3, from the driving form, can be divided into: gear driven steering pump, pulley driven steering pump, cross slide key (spline) steering pump; Among them, the pulley driven steering pump is mainly used for passenger vehicles with small driving torque, and the gear driven type and cross slide key type are more common in commercial vehicles.
