Abstract
The utility model discloses a kind of disk brake guide pin assembling structures of band deflation slot structure.Guide pin is set in the bracket, guide pins are equipped with annular flange, guide pin close to the annular flange side of bracket is equipped with conical surface ring flange, and annular groove is formed between conical surface ring flange and annular flange, and pin dust cover is equipped between conical surface ring flange and bracket end；Conical surface ring flange has cone step, and cone step is towards the multiple air bleed slots being equipped at one end of bracket arrangement, cone step circumferentially uniformly at intervals, and the enclosure space formed between guide pin and pin dust cover is through air bleed slot and extraneous circulation.The utility model can make the gas of compression inside the enclosure space of guide pin and the formation of pin shield be discharged by the air bleed slot on guide pin, will not be caused by its air pressure inside and cross the sliding of the pin shield generation bulging and then influence guide pin of ambassador's rubber material in bracket holes.
Description
Technical field
The utility model relates to the component assembling structures in a kind of disk brake, are specifically related to a kind of band deflation
The disk brake guide pin assembling structure of slot structure.
Background technique
The guide pin of ventional disc brake support frame part, as shown in Figure 1.In guide pin assembling process, guide pin and pin
Shield forms an enclosure space, as shown in Figure 2.When guide pin is mobile to holder orientation, the volume in enclosure space reduces,
And its internal gas can not escape, and become larger so as to cause air pressure in enclosure space.Conference is crossed in air pressure makes the pin shield of rubber material
It generates bulging and then influences sliding of the guide pin in bracket holes.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of disk brake of band deflation slot structure guiding
Assembling structure is sold, the gas in the guide pin enclosure space that guide pin and pin shield are formed in assembling process is enable smoothly to arrange
Out.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is:
The utility model includes guide pin, pin dust cover, air bleed slot and bracket；Guide pin is set in the bracket, guide pin
End be equipped with annular flange, close to bracket annular flange side guide pin be equipped with conical surface ring flange, conical surface ring flange and
Annular groove is formed between annular flange, and pin dust cover is equipped between conical surface ring flange and bracket end；Conical surface ring flange has
Cone step, cone step arrange towards one end close to bracket, and circumferentially uniformly at intervals multiple are equipped at cone step and are put
Air drain, the enclosure space formed between guide pin and pin dust cover is through air bleed slot and extraneous circulation.
The bracket end face is provided with the counterbore that diameter is greater than guide pin, and pin dust cover one end is inlaid in counterbore, another
End is connected to the cone step of guide pin.
The pin dust cover is sleeved on outside guide pin, and pin dust cover is flexible structure.
The guide pin end face is provided with mounting hole.
The guide pin is made of metal material.
The beneficial effects of the utility model are:
The gas being pressurized inside the enclosure space that the utility model can make guide pin and pin shield be formed passes through guide pin
On air bleed slot discharge, will not be caused by its air pressure inside cross ambassador's rubber material pin shield generate bulging so that influence lead
To sliding of the pin in bracket holes.
Detailed description of the invention

Fig. 2 is the enclosure space schematic diagram that guide pin and pin dust cover are formed.
Fig. 3 is the guide pin schematic diagram of the utility model.
Fig. 4 is air bleed slot operation principle schematic diagram on the guide pin of the utility model.
Fig. 5 is the structural schematic diagram of the utility model guide pin after the assembly is completed.
In figure: guide pin 1, pin dust cover 2, air bleed slot 3, bracket 4, enclosure space 5.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 3, the utility model includes guide pin 1, pin dust cover 2, air bleed slot 3 and bracket 4；Guide pin 1 is set with
In the centre bore of 4 end face of bracket, 1 end face of guide pin is provided with mounting hole, and 1 end of guide pin is equipped with annular flange, close to bracket
The guide pin 1 of 4 annular flange side is equipped with conical surface ring flange, and it is recessed that annular is formed between conical surface ring flange and annular flange
Slot is equipped with pin dust cover 2 between 4 end of conical surface ring flange and bracket；4 end face of bracket is provided with the counterbore that diameter is greater than guide pin 1,
Pin 2 one end of dust cover is inlaid in counterbore, and the other end is connected to the cone step of guide pin 1.Pin dust cover 2 is sleeved on guide pin
Outside 1, pin dust cover 2 is flexible structure.
As shown in figure 4, conical surface ring flange has cone step, cone step is arranged towards one end close to bracket 4, the conical surface
Multiple air bleed slots 3 circumferentially uniformly at intervals, the enclosure space 5 formed between guide pin 1 and pin dust cover 2 are equipped at step
Through air bleed slot 3 and extraneous circulation, the enclosure space for forming guide pin 1 between guide pin 1 in assembling process and pin dust cover 2
Gas in 5 can be smoothly discharged from air bleed slot 3.
The course of work of the utility model is: in the assembling process that guide pin 1 is moved to 4 direction of bracket, 1 He of guide pin
The volume for selling the enclosure space 5 that dust cover 2 is formed reduces, and the internal gas being pressurized passes through 3 row of air bleed slot on guide pin 1
Out, as shown in Figure 4.Its air pressure inside will not be caused by cross the generation bulging of pin dust cover 2 of ambassador's rubber material and then influence
Sliding of the guide pin in 4 hole of bracket, what the sliding resistance of guide pin 1 was unfavorable for reducing greatly disk brake drags torque.Guide pin dress
With after the completion as shown in figure 5, pin 2 other end of dust cover is inlaid in the lock ring connected in star of guide pin 1.
