The Power Steering Pump Is The Power Source Of The Hydraulic Power Steering System

The power steering pump is driven by the engine to convert low-pressure oil in the oil tank into high-pressure oil and deliver it to the steering control valve.

effect

1. 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 hydraulic energy into mechanical energy through the hydraulic oil output from the oil pump, thereby reducing the driver's operating intensity and improving the vehicle's maneuverability;.

2. Control the internal pressure of the power steering pipeline through a pressure safety valve to ensure the safety of the steering system; 3. Control the flow of the steering system through a flow control valve to ensure the driver's steering feel when driving at high speeds

classification

1. According to the vehicle model, it can be divided into: commercial vehicle steering pump and passenger vehicle steering pump.

2. From the structural form, it can be divided into: blade type steering pump, gear type steering pump, and plunger type steering pump; The double acting vane steering pump is widely used in various vehicle models due to its advantages of small size, low noise, and high volumetric efficiency.

3. From the driving form, it can be divided into: gear driven steering pump, pulley driven steering pump, and cross key (spline) steering pump; The pulley driven steering pump is mainly used to drive passenger cars with low torque, and gear driven and cross key driven are more common in commercial vehicles.

constitute

At present, most steering pumps used in automobiles are double acting vane pumps, which mainly consist of ordinary double acting vane pumps, flow control valves, and pressure safety valves; The double acting vane pump provides high-pressure oil, and the flow control valve ensures that the steering pump outputs the flow rate suitable for the vehicle's needs. The pressure safety valve controls the maximum output pressure of the steering pump. For gasoline engines with lower engine power, a pressure switch should also be equipped.
