As shown in figure 5, the upper surface of described first elastic-friction piece 7132 is provided with the first raised line 7134, described first is convex
Bar 7134 and the bottom surface sliding contact of described first lug 43, due to the bottom surface contact surface of the first raised line 7134 and first lug 43
Long-pending less, thus, it is possible to reduction frictional force between the two is so that the slip of outside friction disc 4 is more smoothly.Equally, described
The upper surface of two elastic-friction pieces 7232 is provided with the second raised line 7234, described second raised line 7234 and described second lug 33
Bottom surface sliding contact, because the second raised line 7234 is less with the bottom surface contact area of the second lug 33, thus, it is possible to reduce both
Between frictional force so that the slip of inner attrition piece 3 is more smoothly.
In the present embodiment, deformation force and the center of gravity of described inner attrition piece 3 and outside friction disc 4 that described return spring 6 produces
It is in same level.Inner attrition piece 3 and outside friction disc 4 is made to keep balance in return process, it is to avoid inner attrition piece 3 and outer
Run-off the straight during friction plate 4 return and rub with brake disc 5, contribute to reducing further dragging moment.
Return spring, card are arranged on brake caliper assy according to the above embodiment of the present invention, inner attrition piece and outside friction disc
Setting sliding spring in both sides before and after pincers support, before and after inner attrition piece, both sides are slidably connected at the inner side of sliding spring, rub outward
Before and after pad, both sides are slidably connected at the outside of sliding spring, and return spring is in inner attrition piece and outside friction disc to clamping braking
The deformation force contrary with the moving direction of inner attrition piece and outside friction disc is produced when the direction of disk is mobile.So, work as end of braking
When, braking clamp body returns back to initial position, and inner attrition piece and outside friction disc return back to initial position by above-mentioned deformation force, real
Show the active return of inner attrition piece and outside friction disc, thus reducing the moment that drags between brake disc and inside and outside friction plate, fall
The oil consumption of low car load and co2Discharge, reduces atmospheric pollution.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
