The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Refering to shown in Fig. 1-5, the low of the utility model drags spring leaf, and including spring leaf body 1, spring leaf body 1 wraps
The spring leaf root 11, spring leaf middle part 12 and spring leaf afterbody 13 of integral molding are included, 12 bendings are in an arc in the middle part of spring leaf
It is connected respectively with spring leaf root 11 and spring leaf afterbody 13 after shape, wherein, what spring leaf afterbody 13 was outwards turned down equipped with one
Drag hook 14, drag hook 14 are connected with closing on the one side of friction plate 3 on friction plate backboard 2, spring leaf root 11 and 4 phase of a presser feet piece
Connection, the one side of presser feet piece 4 are connected with caliper bracket 5, and opposite side is equipped with a slip clamping piece 6 that outwards fold extends,
Clamping piece 6 is slided to abut against with 2 side wall of friction plate backboard.
The utility model by by 12 bendings in the middle part of spring leaf in after an arc respectively with spring leaf root 11 and spring leaf
Afterbody 13 is connected, and a drag hook 14 outwards turned down is equipped in spring leaf afterbody 13, using drag hook 14 with facing on friction plate backboard 2
The one side of nearly friction plate 3 is connected, and spring leaf root 11 is connected with presser feet piece 4, and makes slip clamping piece 6 and friction plate backboard
2 abut against, so as to when caliper is in non-brake state, drag hook 14 in the middle part of the spring leaf of arc 12 elastic recovery masterpiece
Under, can main belt movable friction plate backboard 2 and friction plate 3 separated with brake disc 7, dawdle effect so as to reach reduction, reduce and make
The idle running of dynamic pincers assembly drags power, is further reduced the kinetic equation loss of vehicle when driving, achievees the effect that energy-saving and emission-reduction.Meanwhile
The structure of spring leaf body 1 is approximate with traditional chip architecture of the spring, and stability is good, and processing and fabricating cost is small and easy for installation.
Specifically, in order to reduce the holding area for sliding clamping piece 6 and friction plate backboard 2, reduce to sliding clamping piece 6
Chucking power slides 6 undulate of clamping piece, and slides and be additionally provided with multiple hollow holes 8 on clamping piece 6, and multiple hollow holes 8 are along slip
The length direction of clamping piece 6 is spacedly distributed.Hollow hole 8 can further reduce presser feet piece 4 and slide the rigidity of clamping piece 6,
So as to be further reduced the chucking power for sliding clamping piece 6, the slip for making friction plate 3 is more smooth, so can also reduce friction plate 3
Power is dragged between brake disc 7.
It is preferred that the width of spring leaf root 11 and spring leaf afterbody 13 is all higher than in the middle part of spring leaf 12 width, so
It can ensure that flexible deformation is occurred mainly in the middle part of spring leaf at 12 position, spring leaf root 11 and spring leaf afterbody 13 are then not
Can deform, thereby may be ensured that friction plate 3 pull back direction and position does not change；The width of spring leaf root 11 compared with
Greatly, it will not be deformed under elastic force, thereby may be ensured that presser feet piece 4 is constant to the clip position of caliper bracket 5.This practicality is new
In type, for the ease of uniform force, spring leaf root 11 and spring leaf afterbody 13 are respectively along the axis pair at spring leaf middle part 13
Claim distribution.
In the utility model, in order to ensure structural strength, procedure of processing, width and the spring leaf afterbody of drag hook 14 are reduced
13 width is adapted.In the present embodiment, slide clamping piece 6 compared with the opposite side of presser feet piece 4 105 ° of fold angle-
150 °, the radian of 12 winding arcs is 270 ° -330 ° in the middle part of spring leaf, drag hook 14 compared with spring leaf afterbody 13 fold angle
Less than 90 °.When so that the friction plate 3 is may wear to extreme position, drag hook 14 will not generate interference with brake disc 7.
Refering to shown in Fig. 6-7, a kind of brake caliper assy, including caliper body 9, piston 10, caliper bracket 5, friction plate backboard 2
With friction plate 3, caliper body 9 is mounted in caliper bracket 5, and piston 10 is mounted on caliper body 9, piston 10 and friction plate backboard 2
Position it is corresponding, and for driving friction plate backboard 2 closer or far from brake disc 7, friction plate backboard 2 and friction plate 3 are mutual
Connection, and respectively symmetrically sets the both sides of brake disc 7, further include it is above-mentioned it is low drag spring leaf, it is low that drag spring leaf symmetrical
It is arranged on the both sides of brake disc.In the utility model, caliper is dragged using common method drop, is generally reduced to 2N.m or so,
And employ the utility model it is low drag spring leaf after, below 1N.m can be dropped to by dragging.
For the utility model when caliper brakes, piston 10 in brake caliper assy is toward extrapolated, and piston 10 is friction plate 3
Push brake disc 7 to, friction plate 3 generates friction brake force after clamping brake disc 7.In this process, the friction plate on friction plate 3
Backboard 2 drives the drag hook 14 of spring leaf afterbody 13 to march forward, at this point, the elastic force of spring leaf body 1 about 20N, compare piston 10
Thrust reach thousands of oxen, the influence of the elastic force of spring leaf body 1 to brake force can be ignored.
When caliper brake release, piston 10 is toward retracting under the action of sealing ring, and piston 10 is to the pressure of friction plate 3
It disappears, friction plate 3 also moves, for adding spring leaf in the case where the rotation of brake disc 7 is scratched toward the direction away from brake disc 7
The brake of body 1, after 10 pressure of piston is shed, spring leaf body 1 can be actively the direction of the past separation brake disc 7 of friction plate 3
It pulls away, the scratch between friction plate 3 and brake disc 7 is greatly decreased, and the idle running of brake 7, which drags, to be equally also greatly decreased.
The above is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
