Abstract
A noise-free type band-type brake of bicycle or electric moped comprises a brake box, a brake plate, a brake steel belt, a brake skin and a brake co-working mechanism, wherein, the brake steel belt is arranged in the inside of the annular top edge of the brake box, the brake skin is arranged in the annular inside of the brake steel belt, and the brake plate is arranged in the brake box. At least one annular slot is arranged along the circumference direction of circumference surface of the brake plate vertical with the end the brake plate and with a certain width. The brake skin adopts a plurality of brake skin blocks of sectional hard frictional material that is glued inside of the brake box steel belt with a gap. The utility model can eliminate noise and prolong the life-span of the brake skin.
Description
Technical field
The utility model relates to a kind of drg that specially is applicable to bicycle and Electrical Bicycle, relates in particular to a kind of noiselessness bicycle that abates the noise and Electrical Bicycle band-type brake.
Background technology
The structure of existing bicycle or Electrical Bicycle band-type brake comprises: fuse-box, circular brake disc, brake steel band, brake rubber block and brake linkage mechanism, and the annular apical margin inboard of fuse-box is provided with the brake steel band, the brake steel band inboard brake rubber block that has been sticked, brake disc is installed in the fuse-box.
The bicycle of this band-type brake or Electrical Bicycle are installed in braking, need with hand application of force on handle, by brake linkage mechanism pulling brake steel band, make it encircle circular metal brake disc apical margin, the non-metal brake rubber block that is positioned at brake steel band medial surface this moment is close to the apical margin of circular metal brake disc, make circular metal brake disc and the mutual friction mutually of nonmetallic brake rubber block, friction face produces the noise of shrillness because of resonance; Simultaneously, this band-type brake after using a period of time, the brake rubber block that weares and teares easily, and the as easy as rolling off a log brake rubber block that makes is from the rivet fracture, and lose braking action.
The utility model content
Technical problem underlying to be solved in the utility model is, overcome the above-mentioned defective that existing noiselessness bicycle or Electrical Bicycle band-type brake exist, and a kind of noiseless bicycle or Electrical Bicycle band-type brake are provided, it not only can abate the noise, and prolongs the service life of brake rubber block.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of noiselessness bicycle and Electrical Bicycle band-type brake comprise fuse-box, brake disc, brake steel band, brake rubber block and brake linkage mechanism, and the annular apical margin inboard of fuse-box is provided with the brake steel band, the annular inboard brake rubber block that has been sticked of brake steel band, and brake disc is installed in the fuse-box; It is characterized in that described brake disc on the circumferential surface with a width vertical with the brake disc end face, along the circumferential direction offers the circular groove of one or more; Described brake rubber block is the brake shoe block that adopts several hard friction materials of segmentation, these several brake shoe blocks be interval type be bonded in fuse-box steel band inboard.
Principle of work of the present utility model is as follows: the utility model is owing to along the circumferential direction be provided with several circular grooves at the brake disc apical margin, when brake, need with hand application of force on handlebar, pass through brake linkage mechanism this moment, make the brake steel band hold metal to-metal brake disc-annular shape apical margin, be positioned at the brake shoe block that the polylith hard friction material of brake steel band medial surface is made this moment, shape is close to the annular ring apical margin of brake disc at interval, because brake disc annular ring apical margin does not have several circular grooves, thereby each brake shoe block is not to be close to brake disc annular ring apical margin uniformly, but there are many circular clearances, and have between adjacent two brake shoe blocks at interval, cause the positive pressure between each brake shoe block and the metal brake disc apical margin, not impartial relatively, but nonlinearities change, thereby can abate the noise.In addition, a plurality of brake shoe blocks that the utility model brake rubber block adopts sectional type to be provided with, promptly a plurality of brake shoe blocks are interruption-like, be bonded in brake steel band inboard securely.And each brake shoe block is made by hard friction material, and durable wear can not be worn easily, owing to be to be bonded in brake steel band inboard securely, does not have breakage problem, so increase the service life.
The beneficial effects of the utility model are that it not only can abate the noise, and prolongs the service life of brake rubber block.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional structure chart of the present utility model.
Fig. 2 is main TV structure figure of the present utility model.
Fig. 3 is the scheme drawing that the utility model sectional type brake shoes is disposed on fuse-box steel band inboard.
Fig. 4 is the scheme drawing that offers circular groove on the utility model brake disc apical margin circumferential surface.
The specific embodiment
See also Fig. 1, Fig. 2, a kind of noiselessness bicycle of the utility model and Electrical Bicycle band-type brake comprise the brake shoe block 4 and the brake linkage mechanism 5 of fuse-box 1, brake disc 2, brake steel band 3, several hard friction materials, the annular apical margin inboard of fuse-box 1 is provided with brake steel band 3, the be sticked brake shoe block 4 of several hard friction materials of the annular inboard of brake steel band 3, three brake shoe blocks 4 of employing are bonded in brake steel band 3 inboards in the fuse-box 1 uniformly in the present embodiment, as shown in Figure 3, the material of this brake shoe block 4 is to adopt the hard material of shape of a hoof brake shoes in the lock that rises.Brake disc 2 is installed in the fuse-box 1; Have on the circumferential surface of width at apical margin vertical on the brake disc 2 with brake disc 2 end faces, along the circumferential direction offer the circular groove 6 of one or more, present embodiment offers two circular grooves 6 on the circumferential surface of brake disc 2 end face apical margins, as shown in Figure 4, the width of every circular groove is 1.5mm, and the degree of depth is 0.25mm.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
