Abstract
The utility model discloses a kind of piston holes of motorcycle brake clamp, the inner wall of the piston hole is equipped with the annular groove for being used to install sealing ring, it is circular supporting table that the bottom of piston hole, which is equipped with section, supporting table is coaxial with piston hole, annular gap is formed between the side of supporting table and the inner wall of piston hole, annular gap is connected to the oilhole of clamp.The upper surface of supporting table has the bellmouth that recess is formed downwards.The diameter of supporting table is gradually increased from top to bottom.The piston hole of the motorcycle brake clamp of the utility model, the bottom chamfer of piston hole will not cause to wear to piston, piston not will form complete be bonded with the bottom surface of piston hole, be conducive to brake oil in clamp and preferably act on piston, the braking effect for improving clamp improves the service life of clamp.
Description
Technical field
The utility model belongs to motorcycle brake clamp technical field, and in particular to a kind of piston of motorcycle brake clamp
Hole.
Background technique
The piston hole for installing piston is equipped in motorcycle brake clamp, in the prior art, piston is being packed into piston hole
In after, the bottom surface of piston and the bottom face contact of piston hole.In process due to piston hole, four weekly assembly of bottom of piston hole
Certain chamfering is formed, therefore, in use, the chamfering of piston hole bottom surrounding can be formed the bottom of piston rubs clamp
It wipes, has grown that will lead to piston impaired the time.It is touched simultaneously as piston bottom surface is completely attached to piston hole bottom surface, it is oily from oil
Hole is difficult directly to act on piston from piston base after entering piston hole, causes the braking effect of clamp undesirable.
Summary of the invention
Aiming at the problems existing in the prior art, the utility model provides a kind of piston hole of motorcycle brake clamp.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of work of motorcycle brake clamp
Consent, the inner wall of the piston hole are equipped with the annular groove for being used to install sealing ring, and it is circle that the bottom of piston hole, which is equipped with section,
The supporting table of shape, supporting table is coaxial with piston hole, and annular gap is formed between the side of supporting table and the inner wall of piston hole, annular
The oilhole of gap connection clamp.
The upper surface of supporting table has the bellmouth that recess is formed downwards.
The diameter of supporting table is gradually increased from top to bottom.
The quantity of annular groove is two, and one of annular groove is used to place the sealing ring of larger specification, another annular
Slot is used to place the sealing ring compared with small dimension, places to be located at compared with the annular groove of small dimension sealing ring and places larger specification sealing ring
The top of shape slot.
The beneficial effects of the utility model are: the piston hole of the motorcycle brake clamp of the utility model, the bottom of piston hole
Portion's chamfering will not cause to wear to piston, piston and the bottom surface of piston hole not will form it is complete be bonded, be conducive to brake in clamp
Oil preferably acts on piston, improves the braking effect of clamp, improves the service life of clamp.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model.
Specific embodiment
Now in conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of piston hole 1 of motorcycle brake clamp, the inner wall of the piston hole 1 is equipped with a for pacifying
The annular groove 2 of sealing ring is filled, it is circular supporting table 3 that the bottom of piston hole 1, which is equipped with section, and supporting table 3 and piston hole 1 are coaxial,
Annular gap 4 is formed between the side of supporting table 3 and the inner wall of piston hole 1, annular gap 4 is connected to the oilhole 5 of clamp.
There is the bellmouth 6 that recess is formed downwards in the middle part of the upper surface of supporting table 3.
The diameter of supporting table 3 is gradually increased from top to bottom.
The quantity of annular groove 2 is two, and one of annular groove is used to place the sealing ring of larger specification, another annular
Slot 2 is used to place the sealing ring compared with small dimension, places to be located at compared with the annular groove 2 of small dimension sealing ring and places larger specification sealing ring
The top of annular groove 2.
The preferred embodiments of the present invention have been described in detail above, it should be understood that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations, therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
