Abstract
The utility model discloses a car ball round pin waterproof construction, including ball round pin dust cover and knuckle, the knuckle is equipped with and is used for holding the spacing block end of ball round pin dust cover and makes ball round pin dust cover and knuckle terminal surface form the spacing block structure that the elastic interference chucking is sealed. The utility model discloses can avoid water to pass through to flow in the ball round pin between ball round pin dust cover and the knuckle, improve water -proof effects, at the auto steering or the suspension is acutely beated and the ageing back of rubber, the waterproof ability of initiative does not reduce, is favorable to improving zero one reliability.
Description
Technical field
This utility model belongs to automobile chassis brake application technical field, is specifically related to a kind of automobile ball pin waterproof construction.
Background technology
Automobile ball pin class waterproof construction at present, main or by self bellows protects.But acutely beating and after ageing of rubber in motor turning or suspension, the waterproof ability of self can reduce.Directly result in ball pin failure after ball pin water inlet, reduce the reliability of parts.
Summary of the invention
This utility model is intended at least to solve one of technical problem present in prior art.To this end, this utility model provides a kind of automobile ball pin waterproof construction, it is therefore an objective to avoid water to pass through between ball pin dust cover and knuckle and flow into ball pin, improve waterproof effect.
To achieve these goals, the technical scheme that this utility model is taked is:
A kind of automobile ball pin waterproof construction, including ball pin dust cover and knuckle, described ball pin dust cover includes that spacing fastening end, described knuckle are provided with for accommodating spacing fastening end and making ball pin dust cover and knuckle end face form the spacing snap-in structure of elastic interference card tightening seal.
Described spacing snap-in structure includes the waterproof groove coordinating clamping spacing with described spacing fastening end.
The Opening length of described waterproof groove is less than the length in waterproof groove inner containment chamber, and described spacing fastening end snaps in the inner containment chamber of waterproof groove by elastic deformation and carries out spacing by the opening of waterproof groove.
Described ball pin dust cover is provided with and water guides the flow-guiding structure deviating from waterproof groove direction.
Described flow-guiding structure includes multiple guiding gutter.
It is provided with sealing structure between described spacing fastening end and waterproof groove.
Described sealing structure is fluid sealant or flexible gasket.
The ball pin of described waterproof construction is provided with the locating slot for coordinating clamping with knuckle.
It is provided with flexible seals between the clamping end face of described locating slot and knuckle.
The material of described ball pin dust cover is elastomeric material.
The beneficial effects of the utility model: this utility model, it can be avoided that water is by flowing into ball pin between ball pin dust cover and knuckle, improves waterproof effect；Acutely beating and after ageing of rubber in motor turning or suspension, actively waterproof ability does not reduces, and is conducive to improving the reliability of zero.This utility model simple in construction, with low cost, and reliability is high.
Accompanying drawing explanation
This specification includes the following drawings, shown content respectively:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
Figure is labeled as:
1, ball pin dust cover, 2, knuckle, 3, ball pin, 4, spacing fastening end, 5, waterproof groove, 6, locating slot.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, it is therefore an objective to help those skilled in the art that design of the present utility model, technical scheme are had more complete, accurate and deep understanding, and contribute to its enforcement.
As shown in Figure 1 to Figure 2, this utility model is specifically related to a kind of automobile ball pin waterproof construction, including ball pin 3, ball pin dust cover 1 and knuckle 2, ball pin is made up of plunger and bearing pin, bearing pin stretches into knuckle 2 by ball pin dust cover 1 and is attached, ball pin dust cover 1 includes spacing fastening end 4, and knuckle 2 is provided with for accommodating spacing fastening end 4 and making ball pin dust cover 1 and knuckle end face form the spacing snap-in structure of elastic interference card tightening seal.The material of ball pin dust cover 1 can be elastomeric material, naturally it is also possible to use other have certain elastic deformation and meet the material making of performance requirement.Ball pin 3 is preferably provided with the locating slot 6 for coordinating clamping with knuckle 2 so that have preferably location clamping effect between ball pin and knuckle.
It is preferred that spacing snap-in structure includes the waterproof groove 5 coordinating clamping spacing with spacing fastening end 4.Clamping is coordinated by waterproof groove 5 and spacing fastening end 4, form sealing effectiveness, the direction making muddy water deviate from waterproof groove from ball pin dust cover 1 flows away, it is to avoid muddy water is connected with knuckle end face by ball pin dust cover and picks out inflow ball pin, and then avoids the risk of ball pin failure.Specifically, can be the Opening length length less than waterproof groove 5 inner containment chamber of waterproof groove 5, spacing fastening end 4 snaps in the inner containment chamber of waterproof groove 5 by elastic deformation and carries out spacing by the opening of waterproof groove 5, defines preferably engaging and seals limit effect；Owing to the spacing fastening end 4 of ball pin dust cover 1 is inside waterproof groove, so after turning to or suspension acutely beats, remaining able to the most waterproof after ball pin dust cover is aging.Use the design of this structure, the most effectively make both seal, be avoided that again the phenomenon of knuckle occurs automatically disengaging in ball pin dust cover.
In order to make muddy water etc. flow away faster, it is to avoid pile up too much muddy water and occur infiltrating through the risk of ball pin, ball pin dust cover 1 is provided with and water guides the flow-guiding structure deviating from waterproof groove 5 direction.It is preferred that flow-guiding structure includes multiple guiding gutter.Guiding gutter can be designed according to the shape of ball pin dust cover, such as to carry over ball pin dust cover 1 incline direction, it is simple to the trend that flowing water flows out is configured.
In order to reach better seal effect, it is to avoid occur that water infiltrates through the risk of ball pin from ball pin dust cover 1 and waterproof groove access section, be provided with sealing structure between spacing fastening end 4 and waterproof groove 5.Sealing structure can be fluid sealant or flexible gasket；Increase sealing, further strengthen waterproof effect.
In order to increase the sealing effectiveness between ball pin and knuckle further, between the clamping end face of locating slot 6 and knuckle 2, it is preferably provided with flexible seals.Flexible seals can be rubber blanket etc..
Above in association with accompanying drawing, this utility model is exemplarily described.Obviously, this utility model implements and is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model design is carried out with technical scheme；Or the most improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
