Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Refering to shown in Fig. 1-5, it is of the invention it is low drag spring leaf, including spring leaf body 1, spring leaf body 1 includes one
Spring leaf root 11, spring leaf middle part 12 and the spring leaf afterbody 13 of body formula shaping, the bending of spring leaf middle part 12 is in after an arc
It is connected respectively with spring leaf root 11 and spring leaf afterbody 13, wherein, spring leaf afterbody 13 is provided with a drag hook outwards turned down
14, drag hook 14 is connected with closing on the side of friction plate 3 on friction plate backboard 2, and spring leaf root 11 is connected with a presser feet piece 4
Connect, the side of presser feet piece 4 is connected with caliper bracket 5, and its opposite side is provided with a slip holding piece 6 that outwards turnover extends, sliding
Dynamic holding piece 6 abuts against with the side wall of friction plate backboard 2.
The present invention by by 12 bendings in the middle part of spring leaf be in after an arc respectively with spring leaf root 11 and spring leaf afterbody
13 are connected, and are provided with a drag hook 14 outwards turned down in spring leaf afterbody 13, are rubbed using drag hook 14 with being closed on friction plate backboard 2
The side of pad 3 is connected, and spring leaf root 11 is connected with presser feet piece 4, and makes slip holding piece 6 and the phase of friction plate backboard 2
Abut, so as to which when caliper is in non-brake state, 12 elastic-restoring force in the middle part of the spring leaf of arc of drag hook 14 acts on
Under, can main belt movable friction plate backboard 2 and friction plate 3 separated with brake disc 7, dawdled effect so as to reach reduction, reduce and brake
The idle running of pincers assembly drags power, further reduces kinetic equation loss during vehicle traveling, reaches the effect of energy-saving and emission-reduction.Meanwhile bullet
The structure of reed 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 of slip holding piece 6 and friction plate backboard 2, reduce to sliding holding piece 6
Chucking power, the undulate of holding piece 6 is slided, and slide and be additionally provided with multiple hollow holes 8 on holding piece 6, multiple hollow holes 8 are along slip
The length direction of holding piece 6 is spacedly distributed.Hollow hole 8 can further reduce presser feet piece 4 and slide the rigidity of holding piece 6,
So as to further reduce the chucking power for sliding holding piece 6, make the slip of friction plate 3 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 elastic deformation occurs mainly in the middle part of spring leaf 12 opening position, spring leaf root 11 and spring leaf afterbody 13 are then not
Can deform, thereby may be ensured that to 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.The present invention
In, for the ease of uniform force, spring leaf root 11 and spring leaf afterbody 13 are respectively along the axisymmetrical at spring leaf middle part 13
Distribution.
In the present invention, in order to ensure structural strength, procedure of processing, width and the spring leaf afterbody 13 of drag hook 14 are reduced
Width is adapted.In the present embodiment, holding piece 6 is slided relative to 105 ° -150 ° of the turnover angle of the opposite side of presser feet piece 4, bullet
The radian of 12 winding arcs is 270 ° -330 ° in the middle part of reed, and drag hook 14 is less than relative to the turnover angle of spring leaf afterbody 13
90°.When the friction plate 3 is may wear to extreme position, drag hook 14 also will not produce 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 arranged in caliper bracket 5, and piston 10 is arranged on caliper body 9, piston 10 and friction plate backboard 2
Position it is corresponding, and for driving friction plate backboard 2 mutual closer or far from brake disc 7, friction plate backboard 2 and friction plate 3
Connection, and respectively symmetrically sets the both sides of brake disc 7, its also include it is above-mentioned it is low drag spring leaf, it is low that to drag spring leaf symmetrical
It is arranged on the both sides of brake disc.In the present invention, caliper is dragged using common method drop, is generally reduced to 2N.m or so, and is adopted
With the present invention it is low drag spring leaf after, to drag can drop to below 1N.m.
For the present invention when caliper brakes, toward extrapolated, piston 10 pushes friction plate 3 to for piston 10 in brake caliper assy
Brake disc 7, friction plate 3 produce friction brake force after clamping brake disc 7.In this process, the friction plate backboard on friction plate 3
The drag hook 14 of 2 drive spring leaf afterbodys 13 marches forward, and now, the elastic force about 20N of spring leaf body 1, the piston 10 that compares pushes away
Power reaches thousands of oxen, and the influence of the elastic force of spring leaf body 1 to brake force can be ignored.
When caliper brake release, piston 10 is in the presence of sealing ring toward rollback, pressure of the piston 10 to friction plate 3
Disappear, 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 the pressure of piston 10 is shed, spring leaf body 1 can be actively the direction of the past separation brake disc 7 of friction plate 3
Pull 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 foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, it should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
