Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
Such as Fig. 1 to 6, brake 700 of the invention includes clamp 710, piston 720, a pair of of Brake pad 730, shaft
740, brake disc 750.Clamp 710 have mutually contradictory installing arm 711 and mounting groove 712, and piston 720 is mounted on the installation
In slot 712.One of Brake pad 730 is fixed in the installing arm 711, another Brake pad 730 is mounted on described
On piston 720.Also the mountable driving part connecting with piston 720, drive brake disc 750 are mobile in installing arm 711.Piston
720 excircle is connect through flexible piece 721 with clamp 710, for stopping external sundries.Brake pad 730 forms a brake cabin
Gap 731, brake disc 750 are fixed in shaft 740, and the brake disc 750 is at least part of to protrude into the brake clearance 731.Braking
When piston 720 drive Brake pad 730 it is close to each other, clamp brake disc 750.Brake pad 730 is installed on clamp 710 through slide-bar
On.Although its length travel is limited, due to the presence of brake force, Brake pad 730 inevitably generates traversing.It is living
Plug 720 and installing arm 711 have a mounting portion 713, and the Brake pad 730 has an ear 732.The mounting portion 713 and ear
Between portion 732 be equipped with an elastic piece 760, elastic piece 760 can reduce Brake pad 730 it is traversing when noise.
Elastic piece 760 is successively made of positioning section 761, linkage section 762, press section 763, rebound section 764, support section 765,
It is connected between each section using arcuate structure.Mounting portion 713 is made of protrusion 714, depressed section 715 and notch 716.Ear
732 have sequentially connected upper surface 733, side 734 and lower surface 735.The length of ear 732 is greater than the depressed section
715 depth.When Brake pad 730 is mobile, ear 732 will not interfere with the movement of linkage section 762.Elastic piece 760 is along mounting portion
The distribution of 713 wall surfaces, limitation ear 732 directly contact with mounting portion 713.Positioning section 761 is installed on the top of protrusion 714
Portion.Specifically, the upper surface of protrusion 714 has an arc groove 717, the positioning section 761 has a curved portion 766,
The curved portion 766 is located in the arc groove 717.The noise when curved portion 766 can reduce the movement of positioning section 761.Linkage section 762
Around protrusion 714, linkage section 762 and protrusion 714 constitute a pulling force deformation gap 701.Press section 763 and recessed portion
715 side wall is divided to be in contact, the upper surface 733 is in contact with press section 763.Press section 763, depressed section 715 and on
Surface 733 constitutes three groups of faces being bonded to each other, and keeps face contact between each other.Brake disc 750 brake when, ear 732 by
It is forced into depressed section 715, upper surface 733 and press section 763 keep face contact.762 deformed in tension of linkage section, press section
763 keep being in close contact with ear 732 with rebound section 764, reduce braking sound.
Rebound section 764 is located in the bottom surface of depressed section 715, between the rebound section 764 and side one rebound deformation of composition
Gap 702.The width in rebound deformation gap 702 is less than pulling force deformation gap 701.Section 765 is supported to stretch out from notch 716, the support
Section 765 is at least part of to be withstood on the lower surface 735.Support section 765 is turnover structure 767, and the turnover structure 767 is at least
One endpoint suppresses the lower surface 735, supports section 765 at least part of between one pressure distortion of the composition of lower surface 735
Gap 703.When 730 forced vibration of Brake pad, supports section 765 is remained to contact with lower surface 735, reduce impact noise.Branch
The deformation for holding section 765 drives rebound section 764 to be bent, and rebound section 764 is contacted with side, and preventing ear 732, further sliding causes
Noise simultaneously improves 732 resume speed of ear.Due to the presence of notch 716, support section 765 when being pressurized in the range of notch 716
Deformation avoids that section 765 and mounting portion 713 is supported to generate contact noise.In the present invention, elastic piece 760 is entrenched in mounting portion 713
It is interior.Cladding face 768 is extended in the two sides of its linkage section 762, press section 763 and the section 764 that rebounds, which is wrapped in
The two sides of the mounting portion 713.
