Abstract
The utility model relates to a friction plate for a brake, which comprises a friction plate body. The axes of the outer arc surface of the friction plate and the axes of the inner arc surface of the friction plate are deviated and are located on the centre line of the friction plate body; the radial thicknesses of all parts of the circumferential direction of the friction plate body are different; and the radial thickness of the middle position of the friction plate body is largest. When brake is carried out, the middle position of the friction plate body firstly is in contact with the inner wall of a brake drum, the initial torque is increased and the brake effect is good; due to the fact that the generated brake torque is the torque generated by a brake shaft relative to the brake, the bias brake can be effectively prevented from happening in the brake process, and the brake safety is enhanced.
Description
Technical field
The utility model relates to a kind of automotive brake brake block, relates to a kind of drum brake friction plate specifically.
Background technique
At present, the structure of the drum brake of automobile generally comprises base plate, brake shoe, brake pump and friction plate, friction plate is fixedly connected on the brake shoe, when automobile carries out skidding, brake pump promotes the brake shoe motion, the friction plate that is positioned on the brake shoe is contacted with the inwall of brake drum, produce braking force, realize brake function.Employed friction plate is an arcuate structure on the drum brake now, the braking axis coinciding of the axle center of the exterior arc surface of friction plate, the axle center of inner arc surface and break, when braking, one end of the close brake pump of friction plate contacts the inwall of brake drum at first, cause the inclined to one side phenomenon of stopping easily, the skidding weak effect, so, when automobile brakes, exist great traffic safety hidden danger in traveling process.
The model utility content
Problem to be solved in the utility model is at above problem, provides a kind of skidding effective, the difficult break friction plate of inclined to one side phenomenon of stopping that produces.
For addressing the above problem, the technological scheme that the utility model adopted is: a kind of break friction plate comprises the friction plate body, the axis deviation setting of the inner arc surface of the axle center of the exterior arc surface of described friction plate body and friction plate body.
As a kind of optimized project, the axle center of the inner arc surface of the axle center of the exterior arc surface of described friction plate body and friction plate body is positioned on the center line of friction plate body.
A kind of concrete optimized project, the braking axis coinciding of the axle center of the inner arc surface of described friction plate body and break.
A kind of concrete optimized project, described friction plate body is along circumferential radial thickness difference everywhere.
A kind of concrete optimized project, the radial thickness maximum at the place, neutral position of described friction plate body, the radial thickness of described friction plate body from middle position to two ends reduces successively.
The utility model is taked above technological scheme, have the following advantages: because the axis deviation of the inner arc surface of the axle center of the exterior arc surface of friction plate body and friction plate body, the axle center of the inner arc surface of the axle center of the exterior arc surface of friction plate body and friction plate body is positioned on the center line of friction plate body, the circumferential radial thickness difference everywhere of friction plate body, the radial thickness at the place, neutral position of friction plate body is the thickest, so when carrying out skidding, the place, neutral position of friction plate body at first contacts with the inwall of brake drum, initial torque increases, skidding is effective, because the brake torque that produces is the moment with respect to the braking axle center generation of break, so effectively avoided the generation of the inclined to one side phenomenon of stopping in the brake process, the Security that has improved skidding.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is the structural representation that a kind of break is used friction plate among the utility model embodiment.
Embodiment
Embodiment: as shown in drawings, a kind of break friction plate comprises friction plate body 1, the axle center O of the exterior arc surface of friction plate body 1
2Axle center O with the inner arc surface of friction plate body 1
1Depart from setting.
The axle center O of the exterior arc surface of friction plate body 1
2Axle center O with the inner arc surface of friction plate body 1
1Be positioned on the center line of friction plate the axle center O of the exterior arc surface of friction plate body 1
2Be positioned at the axle center O of the inner arc surface of friction plate body 1
1Top.
The axle center O of the inner arc surface of friction plate body 1
1Braking axis coinciding with break.
The circumferential radial thickness difference everywhere in friction plate body 1 edge, the radial thickness maximum at the place, neutral position of friction plate body 1, the radial thickness of friction plate body 1 from middle position to two ends reduces successively.
When carrying out skidding, the place, neutral position of friction plate body 1 at first contacts with the inwall of brake drum, initial torque increases, skidding is effective, because the brake torque that produces is the moment with respect to the braking axle center generation of break, so effectively avoided the generation of the inclined to one side phenomenon of stopping in the brake process, the Security that has improved skidding.
