712W47101-2016 Steering Pump, HOWO steering pump

The power steering pump is the core power source of a truck's hydraulic power steering system. Its primary function is to generate and continuously supply high-pressure hydraulic fluid to assist the driver in steering the vehicle easily and precisely.

Function

1. Provide Steering Assistance

Driven by the engine via a belt, the pump converts mechanical energy into hydraulic energy, creating high-pressure fluid. This pressurized fluid is directed to the steering gear, which helps move the steering linkage, significantly reducing the effort required by the driver to turn the steering wheel.

2. Maintain Stable Pressure:

The pump typically contains flow and pressure control valves (e.g., a relief valve) that automatically regulate output pressure and flow based on engine speed and steering demand. This ensures smooth and consistent power assistance under various operating conditions.

3. Drive the Hydraulic System:

Acting as the "heart" of the entire hydraulic power steering system, it provides the continuous fluid flow and pressure required for the system to operate.

Primary Applications

1.Makes steering heavy vehicles (like trucks and lorries) easy and responsive, greatly reducing driver fatigue, particularly during low-speed maneuvering, parking, or reversing.

2.Ensures maximum assistance at low speeds (for easy steering) and appropriately reduced assistance at high speeds (for better road feel and stability), enhancing driving safety.

3.It is an indispensable critical component for all commercial vehicles equipped with hydraulic power steering systems.

In summary, the primary application of the Power Steering Pump 712W47101-2016 is to provide the necessary hydraulic power for the truck's steering system, making driving heavy vehicles easy, safe, and controllable.
