The power steering system is a typical hydraulic servo system, and all processes are realized dynamically: the rotation of the input shaft opens the oil circuit, and the oil pump supplies oil to the working chamber. When the ground resistance is high, the piston does not move, and the oil pressure in the working chamber continues to increase. When the oil pressure increases to a certain extent, the thrust generated on the piston side is large enough to overcome the steering resistance of the wheel, which will push the rack piston to drive the wheel to turn. When the steering resistance of the wheels decreases, the oil pressure in the working chamber will decrease to the point where the wheels can still continue to rotate. At this time, the oil in the other chamber is pushed by the rack piston and returns to the steering oil tank along the return oil path. When the input shaft stops rotating, under the continuous action of the elastic restoring force of the torsion bar and the oil pressure, the oil groove on the input shaft and the oil groove on the valve sleeve return to the middle normally open position, and the oil supplied by the oil pump no longer flows into any cavity, directly returning to the steering oil tank. The above process is repeated until the next steering action starts.

When the steering wheel is not turned, the steering gear rotary valve is in the middle position, and the upper and lower chambers of the steering gear are connected to the oil return tank. At this time, both the upper and lower chambers are low-pressure oil. The hydraulic oil from the Steering Pump returns to the oil tank through the oil return tank, completing oil circulation.

Steering principle: (left-hand and left-hand products) Turn the steering wheel clockwise and the steering arm shaft counterclockwise. Drive the steering pitman arm to rotate counterclockwise and drive the pull rod to move backward to complete a right turn. Steering principle: (right-hand steering, right-hand steering products) Turn the steering wheel clockwise, and the steering arm shaft rotates clockwise, driving the steering pitman arm to rotate clockwise, driving the pull rod to move forward to complete a right turn.

(1) This kind of abnormal sound is a mechanical friction sound, such as "clicking" or "creaking", which is more obvious and crisp (2) The mechanism of such abnormal sound generation: A. The steering column bearing is worn or interfered with; B. Abnormal wear or poor lubrication of the tie rod and straight rod ball joints; C. The kingpin bearing/bushing is worn or poorly lubricated; D. Heavy load abnormal noise, the kingpin and plate spring sink to the limit after the vehicle is loaded, and friction abnormal noise occurs (3) Treatment methods for such abnormal noises: Jack up the front axle and check the mechanical connection parts one by one.

(1) This type of abnormal noise is low-frequency noise, similar to the "buzzing" sound of a cow, which is relatively dull (2) The mechanism of such abnormal sound generation: Any fluctuations in energy can generate acoustic frequencies. When pumping oil, the oil pump generates an original acoustic wave f1 due to pressure fluctuations. The original wave generates a reflected wave f2 as the hydraulic oil flows through the steering high-pressure oil pipe. The original wave generates a reflected wave f3 as the hydraulic oil flows through the steering gear valve port. When two or three of the three acoustic waves f1, f2, and f3 have the same or similar acoustic frequencies, they generate resonance or resonance and emit low-frequency noise, causing abnormal sound in the steering system. (3) Treatment methods for such abnormal noises: The matching resonance of the steering system can be resolved by replacing any system component (steering gear, booster pump, oil pipe, oil tank/filter element).

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 the steering wheel, it will prevent the steering arm shaft, steering nut, and steering screw from rotating. At this time, the input shaft and valve sleeve rotate to the right relative to the steering screw, and the oil inlet groove is separated from the lower cavity oil hole and oil return groove, The upper chamber of the steering gear forms a closed space, and the pressure in the upper chamber gradually increases, thereby pushing the steering nut downward to complete power steering.

·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 with the steering control valve. (2) Semi integral type ·The steering control valve is combined with a mechanical steering gear as a component, while the power cylinder is treated as a separate component (3) Steering booster ·The mechanical steering gear is a stand-alone component, while the control valve and power cylinder are combined into one component

1) Structure ·Consisting of steering cylinder, steering oil pump, energy accumulator, steering power cylinder, steering control valve, and mechanical steering gear 2) Working process ·The steering oil pump operates driven by the engine, and the output pressure oil fills the accumulator. When the accumulator pressure reaches the specified value, the oil pump automatically unloads and idles ·The steering control valve is usually in the closed state. When the driver rotates the steering wheel, the mechanical steering gear pushes the steering control valve into the open position through levers such as the steering rocker arm. The pressure oil in the accumulator flows into the steering power cylinder, and the hydraulic force output through the power cylinder push rod acts on the steering transmission mechanism. ·As soon as the steering wheel stops rotating, the steering control valve returns to the closed position ·In summary, regardless of the position of the steering wheel, whether moving or stationary, high pressure is always maintained in the working pipeline of the hydraulic system.

Hydraulic Power Steering Pump with High Efficiency

Hydraulic Power Steering Pump with High Efficiency

(1) This kind of abnormal noise belongs to high-frequency noise, like the "squeaking" sound of rapid running water in the water pipe (2) Mechanism and treatment method of such abnormal sound: A. When air is mixed in the steering system, the hydraulic oil at the steering gear valve port changes from high pressure to low pressure, and the air is separated from the hydraulic oil to form a blasting sound; Check whether the oil in the oil tank is lacking, whether the filter element is damaged, or whether the joint is loose to absorb air. After that, turn left and right to the pole several times to exhaust the air in the steering system. B. Booster pump overflow noise. Dirty hydraulic oil can clog the filter element. After the filter element is clogged, the pressure difference between the inner and outer sides of the filter element will be too large, resulting in an unstable oil level. When the oil level changes, due to the large negative value on the inner side, it is easy to mix air into the oil inlet pipe, causing the pump to be compressed and generating aerodynamic noise. Therefore, it is necessary to adjust the pressure of the booster pump or replace it.

A series of devices used to change or maintain the driving or reverse direction of a car is called a steering system. The function of the automobile steering system is to control the driving direction of the vehicle according to the wishes of the driver. The steering system of an automobile is crucial to the driving safety of the automobile, so the components of the steering system of the automobile are all referred to as security components. Automobile steering system and Braking System are two systems that must be paid attention to in automobile safety.
