Abstract
The utility model discloses an oil cup assembly for air boosting pumps, which comprises an oil storage cup, an oil cup cover a filter screen positioned inside the oil storage cup, and a rubber bladder partition arranged between the top of the oil storage cup and the oil cup cover to form a vacuum chamber between the rubber bladder partition and the oil cup cover. The vacuum chamber is communicated with the external atmosphere via a vacuum-pumping passage, and the volume of the vacuum chamber changes along with the movement of the rubber bladder partition. An external thread is arranged on the top of the oil storage cup. A vent channel is arranged at the inside bottom of the oil cup cover. The oil cup cover has an internal thread fitting with the external thread of the oil storage cup, and the internal thread is intermittent with thread open slots communicated with the vent channel. The vacuum-pumping passage (7) is defined by the vent channel and the thread open slots. With the arrangement, the utility model avoids the invasion of air dust and moist into the braking fluid, protects the braking fluid from being contaminated by air dust and moist, and prevents the occurrence of oil injection promptly upon braking, thereby ensuring the stability of brake performance.
Description
Technical field
The utility model relates to the air booster pump, relates in particular to air booster pump lubricating cup assembly.
Background technology
At present air booster pump lubricating cup assembly comprises the sealing member between oil storage cup, oil cup cap, oil storage cup and the oil cup cap, the filtering net in the oil storage cup, has a vacuum pumping hole in the central authorities of oil cup cap.Vehicle is frequently braked, and the moment fuel injection event easily takes place in oil cup cap vacuum pumping hole, causes the car load braking weak, influences braking quality; Vacuum pumping is exposed at the surface outside the hole, causes braking liquid to be polluted by dust and water, influences the deceleration and stopping performance of product.
The utility model content
Technical problem to be solved in the utility model is: a kind of pollution and glancing impact moment fuel injection event of stopping koniology and water to braking liquid is provided, thereby guarantees the stable air booster pump lubricating cup assembly of air booster pump deceleration and stopping performance.
Solve this technical problem, the technical solution of the utility model is: a kind of air booster pump lubricating cup assembly, comprise oil storage cup, oil cup cap, be positioned at the filtering net of oil storage cup, be provided with the rubbery human body barrier film between the top of described oil storage cup and the oil cup cap, has vacuum chamber between rubbery human body barrier film and the oil cup cap, have the vacuum pumping passage between this vacuum chamber and the atmosphere, the volume of this vacuum chamber is along with the motion of rubbery human body barrier film changes.
The top of described oil storage cup has outside thread, the oil cup cap inner bottom surface has air channel, oil cup cap has the negative thread adaptive with the oil storage cup outside thread, negative thread is the interruption shape, form the threaded openings groove that communicates with air that is communicated with air channel, the vacuum pumping passage between described vacuum chamber and the atmosphere is made up of air channel and threaded openings groove.
Described rubbery human body barrier film is cup-shaped, it is made up of the connecting portion between seal ring, telescopic movable portion, seal ring and the telescopic movable portion, seal ring is between the top and oil cup cap of oil storage cup, and telescopic movable portion can move back and forth along the centerline direction of rubbery human body barrier film.
Described oil cup cap top has projection, between the projection of this oil cup cap and the lower external face of oil storage cup a connecting band is set.
The utility model air booster pump adopts such structure, and during service brake, the hydraulic oil liquid level of oil storage cup descends, and causes volume increase between hydraulic oil and the rubbery human body barrier film, and pressure reduces, and the movable part of diaphragm of rubber leather bag turns over downwards.When air pressure discharged, the hydraulic oil of hydraulic cylinder turned back in the lubricating cup, and volume reduces between hydraulic oil and the rubbery human body barrier film, and pressure increases, and this moment, the rubbery human body barrier film upwards turned over, and returned to common state.In the retrousse process of rubbery human body barrier film, weakened the application force of high pressure oil, prevented fuel injection event to it; Vacuum is drained into the air from the vacuum pumping passage of vacuum pumping groove and the formation of threaded openings groove simultaneously.Compared with prior art, overcome the drawback that koniology and water directly enter braking liquid by anti-vacuum hole, stopped koniology and water pollution and glancing impact lubricating cup moment fuel injection event, guaranteed that the deceleration and stopping performance of air booster pump is stable braking liquid.
Description of drawings
Below in conjunction with accompanying drawing the utility model air booster pump lubricating cup assembly is done explanation in further detail;
Fig. 1 is the structural representation of the utility model air booster pump lubricating cup assembly;
In Fig. 1,1, connecting band; 2, rubbery human body barrier film; 3, oil cup cap; 4, oil storage cup; 5, filtering net; 6, shoe cream room; 7, vacuum pumping passage; 8, vacuum chamber.
The specific embodiment
Air booster pump lubricating cup assembly comprises oil storage cup 4, oil cup cap 3, filtering net 5, rubbery human body barrier film 2, connecting band 1, rubbery human body barrier film 2 is installed on the top of oil storage cup 4, form a vacuum chamber 8 between diaphragm of rubber leather bag 2 and the oil cup cap, the below of diaphragm of rubber leather bag 2 is a shoe cream room 6.The top of oil storage cup 4 has outside thread, the bottom has an outlet, oil cup cap 3 tops have projection, inner bottom surface has air channel, oil cup cap has the negative thread adaptive with the oil storage cup outside thread, negative thread is the interruption shape, forms the threaded openings groove that communicates with air that is communicated with air channel, air channel and threaded openings flute profile vacuum passage 7 in a row.Diaphragm of rubber leather bag 2 is cup-shaped, it is made up of seal ring, connecting portion, movable part, seal ring is installed between the top and oil cup cap of oil storage cup, telescopic movable portion can move along the centerline direction of rubbery human body barrier film, and the motion of the telescopic movable portion of rubbery human body barrier film can make the volume of vacuum chamber 8 change.One connecting band is set between the lower external face of the projection of oil cup cap 3 and oil storage cup 4, and when opening oil cup cap 3, oil cup cap 3 still keeps being connected with oil storage cup 4, prevents that oil cup cap from arbitrarily placing.
The utility model adopts said structure, and compared with prior art, it is logical to have overcome airborne dust and water Cross the drawback that anti-vacuum hole directly enters brake fluid, stopped airborne dust and water to the pollution of brake fluid Lubricating cup moment fuel injection event when reaching braking has guaranteed that the braking ability of air boosting pump is stable.
