Abstract
The utility model discloses a novel steering gear upper end cap sealing structure which comprises a steering gear shell body and a steering gear upper end cap. The novel steering gear upper end cap sealing structure is characterized in that a counter bore is formed in an opening of a contact surface between the steering gear shell body and the steering device upper end cap, and a rubber seal ring with a rectangular section is arranged in a rectangular circular groove formed in the contact end face between the counter bore and the steering gear upper end cap. Compared with the prior art, the novel steering gear upper end cap sealing structure has the advantages that hidden danger of lubricating oil leakage is eliminated, part machining changes to be easier, parts are easy to assemble, the rubber seal ring does not move relative to the inner wall of a cylinder hole of the shell body in assembling, and the phenomenon of ring cutting cannot occur. The rubber seal ring can also choose a larger amount of compression, reliable sealing effects are guaranteed, and the problem of oil leakage between the ball-nut type steering gear and the steering gear upper end cap is well resolved.
Description
Technical field
The utility model relates to auto parts and components, relates in particular to a kind of novel steering device upper end cap sealing configuration.
Background technique
At present, what adopt between the steering gear housing on market and upper cover is the sealing means of O-ring seals, processing rectangle annular groove on upper cover and external cylindrical surface that housing matches specifically, during assembling, first O-ring seals is inserted in the rectangle annular groove of upper cover, then presses fit into together in the matching hole of housing.This sealing configuration commonly used has proposed very high requirement to design, processing and the assembling of commutator.Such as: the coaxality of sharp edge, seal groove and the matching surface of the tolerance of size of seal groove, the surface roughness of seal groove, seal groove and beat, the large footpath of O-ring seals and tolerance of size of diameter of section etc., these factors all finally can have influence on can O-ring seals reach after completing assembling desired compression amount.Decrement is little can not be sealed, and can cut circle again during assembling that decrement is large.This sealing configuration easily produces the adverse consequences of commutator leakage of oil.
The problem of commutator leakage of oil is the common fault of steering system.The commutator leakage of oil not only affects cleaning, the waste oil plant of passenger-cargo carriage, and can, because of the oil starvation insufficient lubrication, make the wearing and tearing aggravation of each several part, reduce transmission efficiency, shorten the working life of commutator, serious situation meeting ablation screw rod and bearing, can be abnormally dangerous when high vehicle speeds.Particularly circulation ball hydraulic power assisted steering, be hyperbaric chamber in housing, and working pressure up to 10-13MPa, oil leak occurs more easily, can cause the feel that turns to become heavy.
The model utility content
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of novel steering device upper end cap sealing configuration.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of novel steering device upper end cap sealing configuration, comprise steering gear housing and commutator upper end cap, it is characterized in that: the place, aperture of described steering gear housing and commutator upper end cap surface of contact offers counterbore, and contacting with the commutator upper end cap at counterbore and being provided with cross section in the formed rectangle annular groove of end face is rubber rectangular ring.
The utility model advantage compared with prior art is: eliminated the hidden danger of oil leak, part processing becomes simple and easy, and easily assembling, and during assembling, rubber seal and housing cylinder hole inwall do not have relative movement, can not cut the phenomenon of circle.Rubber seal can also be selected larger decrement, guarantees reliable sealing effect, preferably resolves the Leakage between recirculating ball steering gear housing and upper cover.
Description of drawings
Fig. 1 is conventional construction schematic diagram of the present utility model.
Fig. 2 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, conventional steering device upper end cap sealing configuration, comprise steering gear housing 1 and commutator upper end cap 2, processing rectangle annular groove 3 on described commutator upper end cap 2 and external cylindrical surface that steering gear housing 1 matches, during assembling, first O-ring seals 4 is inserted in the rectangle annular groove 3 of upper cover, then presses fit into together in the matching hole of steering gear housing 1.The sealing structure easily produces the phenomenon of commutator leakage of oil.
As shown in Figure 2, a kind of novel steering device upper end cap sealing configuration of the present utility model, comprise steering gear housing 1 and commutator upper end cap 2, it is characterized in that: described steering gear housing 1 is offered counterbore 5 with the place, aperture of commutator upper end cap 2 surface of contact, and contacting with commutator upper end cap 2 at counterbore 5 and being provided with cross section in the formed rectangle annular groove of end face is rubber rectangular ring 6.This structure has solved the problem of commutator leakage of oil.
Above-mentioned embodiment is exemplary, is to be this patent to be comprised the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
