Abstract
The utility model relates to a guide pillar round pin dust cover structure, guide pillar round pin dust cover structure among the concretely relates to braking system. Guide pillar round pin dust cover includes dustproof portion and clamping part, and dustproof portion and clamping part interconnect end to end constitute, and dustproof portion is the cylinder form, is provided with groove structure on the inner wall of the portion of preventing dust, the dustproof connection of after section of a portion clamping part, and the inner wall of clamping part is provided with annular bulge and cyclic annular draw -in groove, annular bulge and the setting of cyclic annular draw -in groove interval. The utility model has the characteristics of it is better to stay oily effect, and lubricating grease runs off lessly, and resistance to slippage is less, and stability is better etc.
Description
Technical field
This utility model is a kind of guide pillar pin dust cover structure and in particular to the guide pillar pin dust cover in brakes is tied
Structure.
Background technology
Existing guide pillar pin dust cover structure presence effect in oil is bad, and grease covers uneven in guide pillar pin periphery
Even, run off not enough faster.
One entitled air-pressure disc brake utility model patent of guide pillar pin, Publication No. CN202768686U, bag
Include pin, in the bottom of pin, be provided with pin-and-hole, described pin-and-hole is the hole of hexangle type.For automobile component, pin is improved to be become
It is integrated after structure with bolt, reduce product cost, decrease the complicated procedures of forming in installation process, make draw bail simultaneously
More simple and practical, the stability of product is improved, and caliper slip is submissiveer freely.Brake caliper used for a long time
Due to the loss of grease in journey, lubrication declines；The stability of brakes is affected, and this structure dust cover with
The contact area of guide pillar pin is larger, increases the frictional force between guide pillar pin and dust cover, leads to clamp skid resistance to increase, from
And affect the overall performance of brake caliper.
Content of the invention
Mainly for poor in oily effect existing for prior art, grease runs off larger this utility model, and sliding hinders
Power is larger, the technical problem such as less stable, provides a kind of effect in oil preferably, grease loss is less, and skid resistance is less,
Stability preferable guide pillar pin dust cover structure.
For achieving the above object, this utility model employs following technical scheme：
Guide pillar pin dust cover includes dustproof part and clamping part, and dustproof part is interconnected to constitute end to end with clamping part, dustproof part
For cylindrical shape, the inwall of dustproof part is provided with groove structure, dustproof part afterbody connection buckle portion, the inwall setting of clamping part
There are annular projection and ring-type draw-in groove, annular projection and ring-type draw-in groove interval setting.
Grease can be resided on dust cover groove structure inwall by groove structure advantages of simple well for a long time,
Reduce the loss of grease, and the covering of lubricating grease uniform, in guide pillar pin periphery, make grease be fully utilized,
Thus playing longer time, lubrication evenly.Groove structure decreases the contact surface of dust cover inwall and guide pillar pin
Long-pending, thus decreasing brake caliper guide pillar pin skid resistance.Brake caliper is made to have more preferable stability during using.
Preferably, groove structure is helical groove structure.
Preferably, clamping part is made up of elastomeric material, the inwall internal diameter of clamping part is collapsible or expansion, and clamping part can draw
Stretch or compress.
Therefore, this utility model has in oily effect preferably, and grease loss is less, and skid resistance is less, and stability is relatively
The features such as good.
Brief description
Fig. 1 is the overall structure diagram of this utility model embodiment.
Description of reference numerals：1- dustproof part, 2- clamping part, 11- groove structure, 21- annular projection, 22- ring-type draw-in groove.
Specific embodiment
For a further understanding of this utility model, with reference to embodiment, this utility model preferred embodiment is retouched
State but it is to be understood that these descriptions are simply to further illustrate feature and advantage of the present utility model, rather than to this practicality
The restriction of new claim.
This utility model provides a kind of guide pillar pin dust cover structure, and as shown in Figure 1, guide pillar pin dust cover includes dust-proof
Portion 1 and clamping part 2, dustproof part 1 is made up of steel material, and clamping part 2 is made up of elastoplast, and dustproof part 1 is with clamping part 2 end to end
It is interconnected to constitute, dustproof part 1 is cylindrical shape, and the inwall of dustproof part 1 is provided with groove structure 11, groove structure 11 is spiral shell
Spin slot structure.Helical groove structure extends to the afterbody of dustproof part 1 from the top of dustproof part 1.
When being lubricated using grease in dust cover, grease flows in dust cover along helical groove structure, spiral
Slot structure, around dust cover inwall, greatly increased the path of grease flowing, extends grease stopping in dust cover
Stay the time, decrease the loss of grease, so that grease is made full use of simultaneously, strengthen the effect of lubrication.
Helical groove structure decreases the contact area of dust cover inwall and guide pillar pin simultaneously, decreases guide pillar pin sliding resistance
Power.
Dustproof part 1 afterbody connection buckle portion 2, the inwall of clamping part 2 is provided with annular projection 21 and ring-type draw-in groove 22, ring-type
Projection 21 and ring-type draw-in groove 22 interval setting.Because clamping part 2 is made up of elastoplast, clamping part 2 is stretchable or compresses, stretching
When, annular projection 21 is increased with the spacing distance of ring-type draw-in groove 22, can increase dust-proof area；During compression, it is suitable for different length
The guide pillar pin of degree.
The inwall internal diameter of clamping part 2 is collapsible or expansion, is suitable for the guide pillar pin of different-diameter, annular projection 21 and ring-type
Draw-in groove 22 can coordinate the step surface on guide pillar pin, makes clamping part 2 fastened to each other with guide pillar pin.
The explanation of above example is only intended to help understand method of the present utility model and its core concept.Should refer to
Go out, for those skilled in the art, on the premise of without departing from this utility model principle, can also be to this
Utility model carries out some improvement and modifies, and these improve and modification also falls into this utility model scope of the claims
Interior.
