Power Steering Pump

Classification of power steering (1) By power and energy 1) Hydraulic type uses hydraulic pressure as the power source and is currently widely used ·The working pressure of the hydraulic power steering system can be as high as 10 MPa or more, so its component size is very small ·The hydraulic system operates without noise, with a short lag time, and can...

Classification of power steering system: Automotive steering systems can be divided into mechanical steering systems and power steering systems based on the energy sources involved in steering. The mechanical steering system relies on the steering force of the steering wheel manipulated by the driver to achieve wheel steering; The power steering system,...

Hydraulic assistance principle: (left handed products) Rotate the input shaft clockwise. The input shaft drives the steering screw to rotate clockwise through a torsion bar. The steering arm shaft rotates counterclockwise, and the steering wheel is driven to rotate to the right through the steering pitman arm and pull rod system. Due to ground resistance on...

Common faults - direction deviation Direction deviation is manifested as: when driving, you feel the car automatically deflecting to one side, and you must firmly hold the steering wheel to maintain a straight driving direction. The reasons are: the pressure of the left and right tires is different; Individual brake shoes scrape the brake hub, or one side...

What is power steering pump? As the power source of the steering of the car, the power steering pump is the "heart" part of the steering system. In developed countries, the installation rate of power steering for large and small cars is close to 100%. At present, many domestic models have begun to use power steering. Therefore, in the process of promoting...

Composition of the power steering pump Currently, automotive steering pumps are mostly double acting vane type steering pumps, which are mainly composed of ordinary double acting vane pumps, flow control valves, and pressure safety valves; The double acting vane pump provides high-pressure oil. The flow control valve ensures that the steering pump outputs...

Selection of steering pipe inlet and outlet pipes: Selection of pipeline material: The pipeline can be flexible pipe, steel pipe, or mixed type. The hose is further divided into high-pressure steel wire braided oil resistant hose, high-pressure oil resistant plastic hose, and low-pressure cord braided oil resistant hose; The steel pipe is high-pressure...

The steering gear ratio Refers to the ratio of the steering wheel steering degree to the wheel steering degree. For example, if rotating the steering wheel once (360 degrees) causes the wheels to turn 20 degrees, the steering gear ratio is equal to 360 divided by 20, or 18:1. The higher the ratio, the greater the amount of steering wheel rotation required...

Structural layout scheme of constant flow steering afterburner ·According to the combination and relative position of the mechanical steering gear, steering control valve, and steering power cylinder, there are three layout schemes as follows (1) Integral type ·The mechanical steering gear and steering power cylinder are designed as one unit and assembled...

Adapt to the needs of high-speed driving of automobiles From the perspective of portability, stability, and safe driving, more advanced technological methods are widely used in automobile manufacturing, including the use of variable ratio steering gears and high rigidity steering gears. "Gear ratio and high rigidity" is the direction of steering gear...

Steering system design requirements 1) When the car is turning, all wheels should rotate around the instantaneous steering center. 2) The steering wheel has an automatic centering capability. 3) Under driving conditions, the steering wheel shall not generate self vibration, and the steering wheel shall not swing. 4) The motion generated by the steering...

Low cost, low fuel consumption, mass specialized production With the deterioration of the international economic situation and the economic recession caused by the oil crisis, automobile production has increasingly attached importance to economy. Therefore, it is necessary to design low-cost, low fuel consumption vehicles and low-cost, rational production...

Steering operating principle The power steering system consists of a steering oil tank 1, a steering oil pump 2, a steering pipeline 3, and a power steering gear 4. During the operation of the steering system, the steering oil pump operates continuously with the engine rotation, sucking oil from the oil tank and supplying oil to the power steering gear...

Function and Application of Power Steering System ·Application: In vehicles with high steering resistance, power steering devices are used ·Steering energy: Only a small portion of the power steering energy is provided by the driver, and most of it is driven by the engine to rotate the steering pump, converting part of the mechanical energy output by the...

Heavy steering Currently, there are several main failure modes for RCB heavy steering: 1. Both left and right turns are heavy 2. Heavy unilateral steering 3. Heavy after heavy load 4. Turning in place is heavy Critical parameters: Working principle of hydraulic power steering pump Steering pumps mainly include vane, gear, plunger and so on. The most used is...

Technical characteristics of steering system During the driving process of a car, it is necessary to frequently change its driving direction according to the will of the driver, which is called vehicle steering. For wheeled vehicles, the method for achieving vehicle steering is for the driver to deflect the wheels (steering wheels) on the steering axle...

Comparison between atmospheric pressure type and constant flow type Normal pressure hydraulic power steering system Advantages: The system always has oil pressure and fast response. Use an energy accumulator to store energy, and use a small oil pump Disadvantages: Easy to cause pressure oil leakage; The oil pump should always maintain pressure, which will...

The usage trends of modern automobile steering devices With the rapid development of the automotive industry, the structure of steering devices has also undergone significant changes. There are many structures of automotive steering gear, and from the perspective of the prevalence of use, there are four main types of steering gear: worm Xiao type (WP type),...
