Abstract
The utility model discloses a kind of integral type brake calipers, including caliper, brake(-holder) block and piston, caliper is equipped with plunger shaft, piston is placed in plunger shaft, plunger shaft is cylindrical, and piston outer wall matches with piston cavity wall, and open slot is equipped on piston, heat-insulation chamber is formed between the open slot and brake(-holder) block, piston outer wall is equipped with sealing mechanism.The technical effect that structure is reliable and brake force is good is just realized in this way.
Description
Technical field
The utility model relates to a kind of motorcycle brake clamp.
Background technique
In order to which brake caliper lightweight and can improve its rigidity, the brake caliper of integral type generally can be all used, one
As brake caliper structure include caliper, brake(-holder) block and piston, piston is mounted on caliper, by brake pump push piston,
Brake(-holder) block is mounted on piston, is realized and is braked by the brake disc CONTACT WITH FRICTION on brake(-holder) block and wheel, and when installing piston,
Seal groove is configured substantially in the plunger shaft of caliper or configures sealing ring step in the port of plunger shaft, results in living in this way
The bore of plug chamber cannot further be expanded, if forcing further expansion, the cavity wall for making piston strong is too thin, influence it just
Property.Since the area of the push power more plunger shaft inner cavity of piston is directly proportional, the internal area of plunger shaft is bigger, and the thrust of piston is just
It is bigger, since the internal area of plunger shaft occupies a part by sealing structure, causes the thrust of piston insufficient, make the braking of vehicle
Braking distance also absolutely not reaches more preferable effect.
Summary of the invention
To solve the above problems, reliably and being braked the technical problem to be solved by the present invention is to provide a kind of structure
The good motorcycle brake clamp of power.
To achieve the above object, the utility model provides following technical solution: a kind of motorcycle brake clamp, including pincers
Body, brake(-holder) block and piston, the caliper are equipped with plunger shaft, and the piston is placed in the plunger shaft, described
Plunger shaft it is cylindrical, the piston outer wall matches with the piston cavity wall, on the piston be equipped with opening
Slot, forms heat-insulation chamber between the open slot and the brake(-holder) block, the piston outer wall is equipped with sealing mechanism.
The sealing mechanism includes the first seal groove and the second seal groove being arranged on the piston body outer wall, in institute
Dustband is configured in the first seal groove stated, and configures sealing ring in second seal groove.
The dust-proof ring outer wall is equipped with the intercepting groove of annular, and the section of the intercepting groove is square.
The slot bottom of second seal groove is inclined to set, the slot bottom of second seal groove and second seal groove
One side wall forms limit acute angle.
This structure of the utility model, compared with existing brake caliper, due to turning the sealing mechanism in plunger shaft
It moves on piston, makes to eliminate seal groove on the port or inner wall of plunger shaft, so that the bore of plunger shaft can be into one
Step expands, and improves the push power of piston, so that vehicle has biggish brake force in braking process, brakes in vehicle brake
Have the effect of shortening braking distance in the process, so that driving is safer, just realizes that structure is reliable and brake force in this way
Good technical effect.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is the enlarged drawing of A in Fig. 1.
Specific embodiment
The utility model is specifically described below by embodiment.
As shown in Figure 1, present embodiment discloses this motorcycle brake clamp, including caliper 1, brake(-holder) block 2 and piston
3, caliper 1 is equipped with plunger shaft 11, is placed with piston 3 in plunger shaft 11, plunger shaft 11 is cylindrical, 3 outer wall of piston and piston
11 inner wall of chamber matches, and open slot 31 is equipped on piston 3, and heat-insulation chamber 4 is formed between the open slot 31 and brake(-holder) block 2, should be every
Hot chamber 4 effectively can prevent heat from conducting to brake fluid, prevent brake fluid because high temperature scatters and disappears conductibility, while in 3 outer wall of piston
It is equipped with sealing mechanism 5.
Wherein, specific as shown in Fig. 2, sealing mechanism 5 includes the first seal groove 51 being arranged on the external wall of piston 3 and the
Two seal grooves 52 configure dustband 6 in the first seal groove 51, and sealing ring 7 is configured in the second seal groove 52.
6 outer wall of dustband is equipped with the intercepting groove 61 of annular, and the section of the intercepting groove 61 is square.Pass through the intercepting groove 61
It can make to form second barrier tape on 6 outer wall of dustband, improve dust-proof effect.
The slot bottom 522 of second seal groove 52 is inclined to set, the slot bottom 522 of the second seal groove 52 and the second seal groove 52
One side wall forms limit acute angle 521.7 inner port of sealing ring can be connected on the limit acute angle 521, and piston 3 is in return, sealing
Circle 7 can be moved by the friction effects of 11 inner wall of plunger shaft to opposite direction, and have such inclined slot bottom 522, can be made close
Seal 7 has extruding and improves sealing performance when opposite direction moves, while the inclined slot bottom 522 further prevents sealing ring 7
Opposite direction movement, improve reliability of structure.
In conclusion the brake caliper of the structure is compared with existing brake caliper, due to by the sealing in plunger shaft 11
Mechanism 5 is transferred on piston 3, makes to eliminate seal groove on the port or inner wall of plunger shaft 11, so that plunger shaft 11
Bore with further expansion, can improve the push power of piston 3, so that vehicle has biggish brake force in braking process,
Have the effect of that shorten braking distance just realizes structure so that driving is safer in this way in vehicle brake braking process
Reliable and good brake force technical effect.
