Abstract
The invention discloses a kind of structure for being used to lift braking clamp piston return amount, including caliper and piston, the piston is slided and is located in caliper, the inwall of caliper is provided with annular groove, the rectangular seal contacted with outside piston week is provided with annular groove, the edge of the rectangular seal, which is provided with, to be used to increase the chamfering or groove of compressive deformation amount.Increase deflection of the rectangular seal in high hydraulic pressure, to avoid the relative slip of the generation of piston and rectangular seal too early, so that the retardance torque of automotive wheel is reduced, the life-span of lifting vehicle fuel utilization rate and brake block.
Description
Technical field
The present invention relates to motor vehicle brake technical field, it is used to lift braking clamp piston return amount more particularly, to one kind
Structure.
Background technology
The sealing function that the braking clamp of disk brake relies primarily on rectangular seal, piston and caliper sets up hydraulic pressure to push away
Dynamic brake block clamps brake disc, so that providing braking moment makes after car deceleration or parking, end of braking, piston is close in rectangle
Return under the drive of seal, makes to produce certain interval between brake block and brake disc, to ensure the normal rotation of brake disc, it is ensured that
The normally travel of vehicle or startup.
Existing brake caliper piston needs to drive to carry out return by the deformation of rectangular seal, when by high hydraulic pressure
When, the deformation of rectangular seal will increase, and relative slip too early can occur for piston and rectangular seal, make brake block and braking
Gap between disk diminishes, so that the retardance torque increase of the wheel of automobile, therefore vehicle fuel can be made to increase and brake block
Service life reduction.
The content of the invention
It is used to lift braking clamp piston in view of the shortcomings of the prior art, the technical problems to be solved by the invention are to provide one kind
The structure of return amount, the relative purpose slided of the generation of piston and rectangular seal too early is avoided to reach.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
This is used for the structure for lifting braking clamp piston return amount, including caliper and piston, and the piston slides and is located at caliper
In, the inwall of caliper is provided with the rectangular seal for being provided with and being contacted with outside piston week in annular groove, annular groove, the rectangular seal
The edge of circle, which is provided with, to be used to increase the chamfering or groove of compressive deformation amount.
Further, the inward flange side of the rectangular seal is provided with chamfering or groove.
The inward flange both sides of the rectangular seal are equipped with chamfering or groove.
The outward flange side of the rectangular seal is provided with chamfering or groove.
The outward flange both sides of the rectangular seal are equipped with chamfering or groove.
Chamfering or groove are equipped with the inward flange of the rectangular seal and outward flange.
Chamfering or groove are provided with chamfering or groove location on the caliper on correspondence rectangular seal.
The groove is arc groove.
The chamfering is chamfer.
The width of chamfering or groove along piston axial direction on the caliper is 0.3-2.0.
The present invention compared with prior art, with advantages below：
This is used for the reasonable in design for lifting braking clamp piston return amount, and chamfering is provided with the inner ring of rectangular seal,
So as to increase deflection of the rectangular seal in high hydraulic pressure, to avoid the generation of piston and rectangular seal too early from sliding relatively
It is dynamic, so that the retardance torque of automotive wheel is reduced, the life-span of lifting vehicle fuel utilization rate and brake block.

Fig. 2 is rectangular seal of the present invention not by hydraulic diagram.
Fig. 3 is rectangular seal of the present invention by hydraulic diagram.
In figure：
1. caliper, 2. pistons, 3. rectangular seals, 4. brake blocks I, 5. brake discs, 6. brake blocks II.
Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation.
As shown in Figure 1 to Figure 3, the structure for being used to lift braking clamp piston return amount, including caliper 1, piston 2, rectangle
Sealing ring 3, brake block I 4, brake disc 5 and brake block II 6, wherein, piston 2 is slided and is located in caliper 1, and the inwall of caliper 1 is set
There is the rectangular seal 3 for being provided with and being contacted with outside piston week in annular groove, annular groove, brake disc 5 is arranged on brake block I 4 and stopped
Between car piece II 6, piston contacts with brake block and brake block motion can be driven to make automobile there is provided brake force so as to clamp brake disc
Slow down or stop；After end of braking, piston return under the drive of rectangular seal makes to produce one between brake block and brake disc
Fixed gap, to ensure the normal rotation of brake disc, it is ensured that the normally travel of vehicle or startup.
The edge of rectangular seal 3, which is provided with, to be used to increase the chamfering or groove of compressive deformation amount.So as to increase rectangular seal
The deflection in high hydraulic pressure is enclosed, to avoid the relative slip of the generation of piston and rectangular seal too early, so as to reduce Automobile
The life-span of the retardance torque of wheel, lifting vehicle fuel utilization rate and brake block.This problem never has in this area to be found, hair
A person of good sense, which studies for a long period of time, finds and solves this problem.
It is preferred that, the inward flange side of rectangular seal 3 is provided with chamfering or groove.Or the inward flange both sides of rectangular seal
It is equipped with chamfering or groove.Or the outward flange side of rectangular seal is provided with chamfering or groove.Or the outward flange of rectangular seal
Both sides are equipped with chamfering or groove.Or chamfering or groove are equipped with the inward flange of rectangular seal and outward flange.
Groove is arc groove.Chamfering is chamfer.Chamfering or groove position on caliper 1 on correspondence rectangular seal 3
Put place and be provided with chamfering or groove.Deflection of the further increase rectangular seal 3 in high hydraulic pressure.Chamfering on caliper 1 or
Width of the groove along piston axial direction is 0.3-2.0.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as employ the present invention design and technical scheme carry out various unsubstantialities improvement, or it is not improved will
The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
