Sinotruk howo truck parts Weichai WP10 power steering pump steering booster pump XG559

Introduction to the power steering pump XG559:

Basic principle: The power steering pump XG559 is usually driven by the engine through a pulley. When the engine is running, it drives the rotor of the power steering pump to rotate, so that the blades form a working chamber together with the stator, rotor, and oil distribution plate under the action of centrifugal force. When the rotor and blades rotate from the small arc area on the inner surface of the stator to the large arc area, the volume of the working chamber increases and the pressure decreases, and oil is sucked through the oil distribution plate suction port; when it turns from the large arc area to the small arc area, the volume of the working chamber decreases and the pressure increases. The high-pressure oil is discharged through the pressure plate oil discharge port and enters the steering gear through the steering oil pipe, thereby providing power for the steering operation.

Application of Power Steering Pump XG559 in Weichai WP10 Engine of Sinotruk HOWO Truck

Power Steering Pump XG559 is crucial in the application of Weichai WP10 engine of Sinotruk HOWO Truck. It works with WP10 engine, obtains power through belt drive, and converts the mechanical energy of engine into hydraulic energy. During the driving process of HOWO truck, especially during low-speed large-angle steering or frequent steering operations, the power steering pump provides stable and sufficient power for the steering system, greatly reducing the driver's operating burden and making steering easier and more precise. It can accurately adjust the pressure and flow of hydraulic oil according to engine speed and driving conditions, and ensure the stability and sensitivity of steering at different speeds. At the same time, under complex road conditions, facing the vibration, temperature changes and other situations that may occur in WP10 engine, XG559 can still operate reliably, ensuring the normal operation of steering system, and playing a key role in the safe driving and good handling performance of HOWO truck.
