Abstract
The utility model discloses a sealing ring for a turning pump of an automobile, which comprises a ring-shaped metal frame.The metal frame is equipped with location holes.A loop of rubber material is fixed to the annular inner periphery of the metal frame.The annular inner periphery of the metal frame is equipped with a loop of convexity and the mating surface of the rubber material matching with the annular inner periphery is equipped with a loop of groove.The convexity matches with the groove.The mating end of the rubber material far from the annular inner periphery is equipped with a seal flange.According to the combination sealing ring for automobile turning pumps of the utility model, the metal frame is adopted to ensure the strength of the sealing ring and prolong the service life thereof.Meanwhile, a loop of rubber material fixed to the annular inner periphery of the metal frame and sandwiched between the rear cover and the pump housing is elastically deformed, thereby ensuring the sealing property between the rear cover and the pump housing.
Description
Technical field
The utility model relates to a kind of auto steerer, particularly relates to a kind of seal ring that steering pump of automobile is sealed of being used for.
Background technique
Domestic and international existing automobile in order effectively to alleviate driver's labor intensity, makes its light driving, generally is provided with steering pump of automobile in the steering gear of automobile, and by the power-assisted effect of steering pump of automobile, the driver can make vehicle steering wheel rotate with less power.Because steering pump of automobile is when work, there is higher oil pressure in the pump housing, sealing to the rear end cover of steering pump and pump case inside is particularly important, existing sealing to steering pump of automobile is adopted usually between the rear end cover of steering pump and pump case a paper paper tinsel seal ring is set, the rear end cover of steering pump is connected with pump case by bolt, but, the paper paper tinsel is because its elasticity is less, making between rear end cover and the pump case sometimes can't effective seal, in addition, because the intensity of paper paper tinsel is less, makes its working life shorter, need periodic replacement.
The model utility content
For overcoming above-mentioned defective, the utility model aims to provide a kind of combined type packing ring that steering pump of automobile is sealed of being used for.Its sealability and working life super existing paper paper tinsel seal ring all far away.
For achieving the above object, the technical solution adopted in the utility model is: a kind of seal ring that is used for steering pump of automobile, comprise the metal frame of ring-type, and described metal frame is provided with positioning hole, is fixed with a circle rubber body in the annular of described metal frame on week.
Be provided with a circle projection in the annular of described skeleton week, the fitting surface in week is provided with a circle groove in described rubber body and the annular, and described projection and groove are complementary.
Described rubber body is provided with sealing flange away from the abutting end with interior week of annular.
The quantity of described positioning hole is 4-8.
Adopted the seal ring that is used for steering pump of automobile of the present utility model, because it has adopted metal frame, guaranteed the intensity of seal ring, thereby prolonged the working life of seal ring, simultaneously, because be fixed with a circle rubber body in the annular of its metal frame on week, rubber body is sandwiched between rear end cover and the pump case resiliently deformable takes place, and has guaranteed the sealability between rear end cover and the pump case.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to partial enlarged drawing.
Among the figure: 1-metal frame, 2-positioning hole, week in the 3-rubber body, 4-annular, 5-projection, 6-groove, 7-sealing flange.
Embodiment
As shown in Figure 1, the utility model discloses a kind of seal ring that is used for steering pump of automobile, the metal frame 1 that comprises ring-type, described metal frame 1 is provided with positioning hole 2, the shape of the skeleton 1 of ring-type should be identical with junction plane shape between the pump case with the rear end cover of steering pump of automobile, the position of positioning hole 2 be provided with also should and the rear end cover of steering pump of automobile and the bolt position between the pump case be complementary, main innovate point of the present utility model is to be fixed with a circle rubber body 3 on week 4 in the annular of described metal frame 1.When the rear end cover of steering pump of automobile and pump case by bolt together the time, rubber body 3 seals the rear end cover of steering pump of automobile and the junction plane between the pump case as sealing surface.
As shown in Figure 2, in order to make the fixing more firm of week 4 in rubber body 3 and the annular, be provided with a circle projection 5 in the annular of described skeleton 1 week 4, the fitting surface in week 4 is provided with a circle groove 6 in described rubber body 3 and the annular, and described protruding 5 are complementary with groove 6.Because fixing the employing usually in rubber body 3 and the annular between week 4 is adhesively fixed, by being provided with projection 5 and groove 6, rubber body 3 and the annular bonded area between interior week 4 is increased greatly, and the bonding intensity between week 4 increases greatly in rubber body 3 and the annular thereby make.
In addition, for the rear end cover that further guarantees steering pump of automobile and the sealability between the pump case, as shown in Figure 2, described rubber body 3 away from annular in the abutting end in week 4 be provided with sealing flange 7.Two planes that described sealing flange 7 needs above metal frame 1, because sealing flange 7 is above metal frame 1 plane, when the rear end cover of steering pump of automobile and pump case link together by bolt, the junction plane of rear end cover and pump case all is pressed on the sealing flange 7 of rubber body 3, simultaneously, because the material rubber of rubber body 3 has certain elasticity, compressing by rear end cover and pump case, make sealing flange 7 that resiliently deformables take place and sturdy on the junction plane of rear end cover and pump case, thereby guaranteed the sealability between rear end cover and the pump case.
Quantity by positioning hole 2 can be set to 4-8.Concrete quantity should be identical with connecting bolt quantity between the pump case with the rear end cover of steering pump of automobile, and when rear end cover and pump case linked together by bolt, connecting bolt also need pass positioning hole 2 simultaneously.
