Description
Technical field
The present invention relates to motor vehicle brake technical field, 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 establishes hydraulic pressure to push away
Dynamic brake block clamps brake disc, makes car deceleration or parking so as to provide braking moment, after end of braking, piston is close in rectangle
Return under the drive of seal, make to produce certain interval between brake block and brake disc, to ensure the normal rotation of brake disc, ensure
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 increase and brake block can be made
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, the piston slide and be located at caliper
In, the inwall of caliper is provided with annular groove, and the rectangular seal contacted with outside piston week, the rectangular seal are provided with annular groove
The edge of circle is provided with the chamfering or groove for being used for increasing 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.
Corresponded on the caliper and chamfering or groove are provided with the chamfering or groove location on 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, has advantages below：
This is used to lift the reasonable in design of 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 piston and the too early generation of rectangular seal relatively sliding
It is dynamic, so as to reduce the retardance torque of automotive wheel, lift the life-span of vehicle fuel utilization rate and brake block.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is clamp structure schematic cross-sectional view of the present invention.
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, embodiment of the invention is made 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 annular groove, the rectangular seal 3 contacted with outside piston week is provided with 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 clamp brake disc, there is provided brake force makes automobile
Slow down or stop；After end of braking, piston return under the drive of rectangular seal, make to produce one between brake block and brake disc
Fixed gap, to ensure the normal rotation of brake disc, ensure normally travel or the startup of vehicle.
The edge of rectangular seal 3 is provided with the chamfering or groove for being used for increasing compressive deformation amount.So as to increase rectangular seal
Enclose deflection in high hydraulic pressure, with avoid piston and rectangular seal it is too early generation it is relative slide, so as to reduce Automobile
The retardance torque of wheel, lift the life-span of vehicle fuel utilization rate and brake block.This problem is never found in this area, is sent out
A person of good sense, which studies for a long period of time, finds and solves this problem.
Preferably, 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.The chamfering on rectangular seal 3 or groove position are corresponded on caliper 1
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 present invention specific implementation is 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.
