Abstract
The utility model relates to an oil distribution disc for an automobile steering power-assisted pump, which belongs to the technical field of the manufacture of an automobile steering power-assisted mechanism. The utility model is mainly composed of an oil distribution disc (1), an oil absorption window (2), an oil pressing window (3), a sealing area (4), etc., wherein the oil distribution disc (1) is arranged in a pump body; the oil absorption window (2) and the oil pressing window (3) are symmetrical mutually; an outer circle of the oil distribution disc (1) forms an orbicular structure. The proportion occupying the circumference of the oil distribution disc (1) by an oil absorption angle theta 1 and an oil pressing angle theta 2 of the oil absorption window (2) and the oil pressing window (3) can be respectively from 25% to 30%, the proportion occupying the circumference of the oil distribution disc (1) by an angle gamma 1 and an angle gamma 2 of the sealing area (4) between the oil absorption window (2) and the oil pressing window (3) can be respectively from 18% to 25%, and from 20% to 30%. The utility model carries out the optimum design for the oil distribution disc to cause the oil absorption of the automobile steering power-assisted pump to be sufficient, therefore the phenomena of empty absorption and insufficient oil absorption of the pump are prevented effectively, the noise of the pump is reduced, the service life of the automobile steering power-assisted pump is extended, and the comfort and the safety for driving and sitting are improved.
Description
Technical field
The utility model relates to a kind of Car Transformation Booster Pump Using For Oil Distribution Window, belongs to the manufacturing technology field of motor turning servomechanism.
Background technique
Along with the develop rapidly of automotive industry, people also have higher requirement to the performance of automobile hydraulic steering system to the travelling comfort of driving, the raising of security requirement.Existing boosting pump for car steering mainly is made up of the pump housing, pump cover, pump shaft, stator, rotor, blade, oil distribution casing, flow pressure control valve etc.Press the design of oily angle improper owing to inhale on the oil distribution casing, be easy to generate noise, it is stable also to influence the motor turning power-assisted.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and using effect is good, can effectively reduce noise, guarantees the stable Car Transformation Booster Pump Using For Oil Distribution Window of motor turning power-assisted.
The utility model is a Car Transformation Booster Pump Using For Oil Distribution Window, comprises the oil distribution casing that places in the pump housing, and the cylindrical that it is characterized in that oil distribution casing is positive round structure, and oil distribution casing is provided with the oil sucking window of mutual symmetry and presses oily window and sealing area.
The oil sucking window and the ratio of pressing the oil suction angle θ 1 of oily window and pressing oily angle θ 2 to account for the oil distribution casing circumference can be respectively 25～30% on the described oil distribution casing, oil sucking window and press the angle γ 1 of sealing area between the oily window and ratio that γ 2 accounts for the oil distribution casing circumference can be respectively 18～25% and 20～30%.
The utility model compares analysis by principle and the structure to existing boosting pump for car steering, thinks that influence boosting pump for car steering output fluid pulses that to cause the bigger one of the main reasons of noise be to have defective in the design of oil distribution casing.By oil distribution casing being optimized design, the rational oil suction angle of the ratio that on oil distribution casing, is provided with θ
1, press oily angle θ
2And the angle γ of formation sealing area
1And γ
2Make the oil suction of boosting pump for car steering more abundant, effectively prevented not foot phenomenon of the empty and oil suction of the suction of pump, reduced the noise of pump.Overall construction design is reasonable, and using effect is good, has reduced the other noise of pump effectively, has eliminated and has driven the indoor noise that turns to, and in the working life of having improved boosting pump for car steering, the travelling comfort of driving and Security is improved.
Description of drawings
Accompanying drawing is an overall structure schematic representation of the present utility model.
Embodiment
The utility model places oil sucking window 2 symmetrical mutually on the oil distribution casing 1 and presses formations such as oily window 3 and sealing area 4 mainly by the oil distribution casing 1 that places in the pump housing.The cylindrical of oil distribution casing 1 is positive round structure, the oil suction angle θ of oil sucking window 2 and the oily window 3 of pressure
1With the oily angle θ of pressure
2The ratio that accounts for oil distribution casing 1 circumference can be respectively 25～30%, oil sucking window 2 and press the angle γ of sealing area 4 between the oily window 3
1And γ
2The ratio that accounts for oil distribution casing 1 circumference can be respectively 18～25% and 20～30%.
During work, by 2 (the angle θ of the oil sucking window on the oil distribution casing 1
1) will turn to the fluid in the oil can to suck pressing chamber by oil inlet hole, again by the oil of the pressure on the oil distribution casing 1 window 3 (angle θ
2) fluid is pressed into pump chamber, output to the work of direction machine by oil outlet.
Claims (2)
1, a kind of Car Transformation Booster Pump Using For Oil Distribution Window, comprise the oil distribution casing (1) that places in the pump housing, the cylindrical that it is characterized in that oil distribution casing (1) is positive round structure, and oil distribution casing (1) is provided with the oil sucking window (2) of mutual symmetry and presses oily window (3) and sealing area (4).
2, by the described Car Transformation Booster Pump Using For Oil Distribution Window of claim 1, it is characterized in that the ratio that described oil distribution casing (1) is gone up the oil suction angle θ 1 of oil sucking window (2) and the oily window of pressure (3) and pressed oily angle θ 2 to account for oil distribution casing (1) circumference is respectively 25～30%, the angle γ 1 of sealing area (4) and the ratio that γ 2 accounts for oil distribution casing (1) circumference are respectively 18～25% and 20～30% between oil sucking window (2) and the oily window of pressure (3).
