The upper surface of two elastic-friction pieces 7232 is provided with the second raised line 7234, second raised line 7234 and second lug 33
Both bottom surface sliding contact, since the bottom surface contact area of the second raised line 7234 and the second lug 33 is smaller, thus, it is possible to reduce
Between frictional force so that the sliding of inner attrition piece 3 is more smoothly.
In the present embodiment, the center of gravity of deformation force and the inner attrition piece 3 and outside friction disc 4 that the return spring 6 generates
In same level.So that inner attrition piece 3 and outside friction disc 4 keep balancing in return process, inner attrition piece 3 and outer is avoided
Run-off the straight when 4 return of friction plate and rub with brake disc 5, help to further decrease and drag torque.
Return spring is set on brake caliper assy according to the above embodiment of the present invention, inner attrition piece and outside friction disc, is blocked
Sliding spring is arranged in the front and rear sides for clamping bracket, and the front and rear sides of inner attrition piece are slidably connected at the inside of sliding spring, rub outside
The front and rear sides of pad are slidably connected at the outside of sliding spring, and return spring is braked in inner attrition piece and outside friction disc to clamping
The deformation force opposite with the moving direction of inner attrition piece and outside friction disc is generated when the direction of disk is mobile.In this way, working as end of braking
When, braking clamp body returns back to initial position, inner attrition piece and outside friction disc and returns back to initial position by above-mentioned deformation force, real
The active return of inner attrition piece and outside friction disc is showed, to reduce the torque that drags between brake disc and inside and outside friction plate, has dropped
The oil consumption of low vehicle and CO2Discharge reduces atmosphere pollution.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
