Electric power steering motor

Compared to traditional steering systems, electric power steering systems offer many advantages, reflected in higher system efficiency and driving comfort. It is reassuring that in some applications, fuel consumption has been reduced by 6%, which corresponds to a decrease of about 8 grams of carbon dioxide emissions per kilometer. Extremely low cogging torque, low noise, and high power density are the main advantages of Mahle EPS motors. To ensure functional safety, we offer additional options such as dual-wound stators.

Electric power steering motor

The electric power steering system provides power assistance directly from the motor, eliminating the need for hydraulic power steering pumps, hoses, hydraulic oil, belts, and pulleys that are required in hydraulic power steering systems installed on the engine. It can save energy and protect the environment. The electric power steering system is the development direction of automotive steering systems, especially for passenger car steering systems.

Electric steering motor

The electric power steering motor uses the power generated by the motor to assist the driver in steering. The components of EPS generally include a torque (steering) sensor, electronic control unit, motor, reducer, mechanical steering device, and auxiliary battery power supply. Compared to mechanical hydraulic power steering systems, electric power steering systems only require power and do not need hydraulic systems, thus eliminating many components. There are no oil pumps, oil pipes, pressure and flow control valves, or oil tanks. The hydraulic system requires fewer parts, is easy to arrange, and is lightweight. Additionally, there are no parasitic losses or fluid leakage losses. Therefore, the electric power steering system can save about 80% energy under various driving conditions, improving the vehicle's driving performance. As a result, it has rapidly gained popularity in recent years and is the direction for the future development of power steering systems.

High-quality power steering pump

The hydraulic power steering pump is a component of the hydraulic power steering system, providing pressurized fluid to assist in steering. The pump is typically driven by the engine and operates using a belt or pulley system. When the driver turns the steering wheel, the power steering pump delivers fluid to the steering gear, which helps reduce the effort required to turn the steering wheel. The pump is usually located at the front of the engine, near the steering rack or gearbox. Maintaining the power steering pump and fluid level is important to ensure proper steering function and prevent system damage.

Low Noise Power Steering Pump

After the drive wheel drives the rotor to rotate, the blades open under the action of centrifugal force, forming a working chamber with the stator, rotor, and oil distribution plate. When the rotor and blades rotate from the small arc area of the inner surface of the stator to the large arc area, the volume between the two blades increases and the pressure decreases. Oil is drawn in through the oil inlet of the oil distribution plate; when moving from the large arc area to the small arc area, the volume between the two blades decreases and the pressure increases. Oil is discharged through the oil outlet of the pressure plate. The discharged high-pressure oil enters the steering gear through the steering oil pipe, playing a role in steering assistance.

High-performance power steering pump

The power steering pump is usually located in the engine compartment. It uses hydraulic power, driven by the car's engine through a belt and pulley system. This pushes fluid into retractable blades in the steering box, which in turn helps keep your steering nice and light. Every time you turn the steering wheel, the blades open, allowing high-pressure fluid to enter one side, making steering easier. So, while you control your driving direction, the power steering pump does most of the hard work for you. In any hydraulic system, the pump is crucial for the efficiency of your power steering.

According to the drive form, it can be divided into: gear-driven steering pump, belt-driven steering pump, and cross slider (spline) steering pump; the pulley-driven steering pump is mainly used for driving passenger cars with smaller torque, while the wheel drive and cross slider type are more common in commercial vehicles.

Low Noise Power Steering Pump

The power steering pump in a car, commonly referred to as the steering power pump, is the power source of the car's power steering system and is also the heart of the steering system. For heavy vehicles, due to the mechanical steering mechanism, the driver's operation is labor-intensive, making the hydraulic steering system even more important. The commonly used servo booster pumps in cars are divided into vane type and gear type. Here, we will focus on the vane servo booster pump.

Durable power steering pump

The blade pump generally consists of a pump body with an inner cavity of double arc curves, a slotted rotor, blades, and other components. Some are installed on the flywheel housing at the rear end of the engine and are also driven by timing gears. When the engine operates, it drives the rotor of the booster pump to rotate, and the blades move outward along the blade slots under the action of centrifugal force, approaching the inner wall of the pump body. During the rotation of the rotor, the enclosed volume between the blades continuously increases and decreases, achieving the process of oil suction and oil pressure. Each rotation of the rotor completes both oil suction and oil pressure twice. There is also a safety valve in the pump body to limit the maximum pressure. When the external load of the steering system increases, causing the oil pressure to rise to a certain value, the safety valve opens to unload the load. A throttle valve and a flow control valve are also installed in the pump body to ensure that the displacement of the booster pump remains basically stable.

Custom Power Steering Pump

The power steering pump, as the power source for car steering, is the "heart" of the steering system. In developed countries, the installation rate of power steering in both large and small vehicles has approached 100%. Currently, many domestic car models have begun to adopt power steering. Therefore, in the process of promoting and using steering pumps, it is necessary to understand and master their performance and principles to achieve correct use and maintenance.

From the perspective of drive type, hydraulic power steering pumps can be divided into gear-driven steering pumps, belt-driven steering pumps, and cross-key (spline) steering pumps. Among them, belt-driven steering pumps are mainly used for passenger cars with lower torque, while gear-driven and cross-key steering pumps are more commonly used in commercial vehicles.

Automotive hydraulic power steering pump

The power steering pump pressurizes the hydraulic oil, assisting the driver in turning the steering wheel. Signs of a steering pump failure include leaks, noise, or reduced assistance when steering. An immediate loss of power assistance is more likely a sign of a broken drive belt or loss of steering fluid. Most vehicles use this mechanical/hydraulic power steering system, but a small number of cars use electric pumps since the pump also affects power and efficiency when the vehicle is not turning; many new cars now have electric power steering systems.

The term "hydraulic" is just a fancy word for using liquids, which can refer to water, oil, etc. In this case, we use bright pink hydraulic steering fluid for our car.

Modern Hydraulic Power Steering Pump

The steering pump should be securely mounted on the pump bracket, ensuring that the pump pulley, engine crankshaft pulley, and tension pulley are on the same plane. The belt should be tensioned using a tension pulley or other tensioning methods. Tension force: New belt: 45~55 kgf, Old belt: 35~45 kgf.

Efficient Power Steering Pump

Inspection Analysis: The bracket on the installation pump is loose; the oil level in the power steering system is too low or there is insufficient air; the filter element in the oil cup is very dirty, leading to insufficient oil suction by the steering pump. The internal cleanliness of the power steering system is poor, resulting in excessive wear of the stator, rotor, oil distributor, end cover, and oil pump input shaft.

The power steering pump noise is good.

Under the premise that other components are fault-free, check whether the steering fluid is insufficient, whether there is air in the hydraulic system, and whether the steering system is too dirty, causing the steering pump flow control valve to jam.

Affordable Power Steering Pump

The power steering system consists of the steering oil tank 1, steering pump 2, steering pipeline 3, and power steering device 4. During the operation of the steering system, the steering pump continuously works with the rotation of the engine, sucking oil from the tank and supplying it to the control valve of the power steering device. When there is no steering action, the control valve is in a normally open middle position, and the oil directly returns to the steering oil tank through the control valve.

Quality assured power steering pump

The power steering system includes the steering pump, hydraulic cylinder, and hydraulic control valve. When the driver turns the steering wheel, the steering pump draws hydraulic oil from the reservoir and directs it to the hydraulic cylinder. The pressure of the hydraulic oil causes the piston of the hydraulic cylinder to move left or right, turning the wheels.

Power steering pump with a good warranty period

The mechanical hydraulic power system mainly includes the rack and pinion steering structure and the hydraulic system (hydraulic power pump, hydraulic cylinder, piston, etc.). Its working principle is that the hydraulic pump (driven by the engine belt) provides oil pressure to push the piston, which in turn generates auxiliary force to push the steering rod, assisting the steering of the wheels.

Efficient Power Steering Pump

When installing the steering pump, consider whether there is any trapped air inside the pump body, and take venting measures if necessary. Air should be expelled from the steering system, usually it is sufficient to vent air from the oil outlet of the steering pump. The specific method is to loosen the oil outlet joint while the engine is not running, and then tighten it if there is any oil leakage. At this point, start the engine and turn the steering wheel left and right; all the air will be expelled into the oil reservoir and released into the air through the breather.
