Abstract
A brake shoe for a motorcycle comprises an circular arc-shaped shoe and a brake block adhered to the outer side of the convex surface of the circular arc-shaped shoe, wherein the circular arc-shaped shoe comprises a circular arc-shaped frame and a support part extending from the concave arc-shaped surface to the center of the circular arc-shaped frame; the circular arc-shaped frame and the support part are integrally formed; through hole for mounting tension springs are symmetrically formed in the surface of the support part; a plane end surface is arranged at one end of the circular arc-shaped shoe; and a concave arc-shaped surface is arranged at the other end of the circular arc-shaped shoe. Compared with the prior art, the brake shoe provided by the utility model has the characteristics of high overall strength, stability and firmness in stress, long service life and the like.
Description
Technical field
The utility model relates to drum brake system, and what be specifically related to is that a kind of motorcycle is used shoe piece.
Background technique
Drum brake system is generally formed the only common at present trailing wheel that is used in by relevant connecting rods such as shoe sole, wheel cylinder, brake shoes, spring, tip nail, brake drum; Be to lean on shoe piece on Brake drum, to compress to realize the purpose of braking, its brake block is positioned at the Brake drum inboard, and when brake, shoe piece opens outward, and the inboard of friction catch wheel reaches the purpose of brake.
Existing most shoe piece is as shown in Figure 1; Include circular arc shoes 2 and the brake block 1 that is bonded in circular arc shoes 2 convex side; Said shoes 2 is formed by circular arc skeleton 21 and by the supporting portion 23 that circular arc skeleton 21 concave arc surfaces stretch out to the center; And settings that be formed in one of circular arc skeleton 21 and supporting portion 23 also is arranged with lug 24 on the marginal end of said this supporting portion 23, lug 24 surfaces are provided with the fastening through hole 22 of confession extension spring.Because in the said structure, lug 24 is located on the marginal end of supporting portion 23, when the needs braking brake; Shoe piece opens outward, and the extension spring moment that is installed in the through hole on the lug 24 22 is stressed, makes the inboard of brake block 1 friction catch wheel; Reach moment brake, through behind the skidding repeatedly, its lug more than 24 time is stressed; Fracture easily, whole shoe piece needs to change again in case lug 24 ruptures.Traditional shoe piece is short working life.
Summary of the invention
The purpose of the utility model is the deficiency to existing technology, and a kind of reasonable in design is provided, long service life and further save raw-material motorcycle and use shoe piece.
The utility model is realized through following technological scheme: motorcycle is used shoe piece; Include circular arc shoes and the brake block that is bonded in circular arc shoes convex side; Said circular arc shoes is formed by the circular arc skeleton and by the supporting portion that circular arc skeleton concave arc surface stretches out to the center; And the setting that is formed in one of circular arc skeleton and supporting portion is characterized in that: the said through hole that supplies extension spring to install that on abutment surfaces, is arranged with.
One termination of said circular arc shoes is made as flat end face, and another termination is made as concave arc surface.
The beneficial effect of the utility model embodies and is: compared with prior art, the utility model shoe piece has the bulk strength height, stability under loading, firm, and characteristics such as long service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed explanation.
Fig. 1 is traditional shoe piece structural representation.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model example structure schematic representation.
The concrete title of each sign among the figure: 1 brake block, 2 circular arc shoes, 21 circular arc skeletons, 22 through holes, 23 supporting portions, 24 lugs.
3 brake blocks, 4 circular arc shoes, 41 concave arc surfaces, 42 supporting portions, 43 through holes, 44 flat end faces, 45 circular arc skeletons.
Embodiment
Extremely shown in Figure 3 like Fig. 2; Motorcycle is used shoe piece; Include circular arc shoes 4 and the brake block 3 that is bonded in circular arc shoes 4 convex side; Said circular arc shoes 4 is formed by circular arc skeleton 45 and by the supporting portion 42 that circular arc skeleton 45 concave arc surfaces stretch out to the center, and the setting that is formed in one of circular arc skeleton 45 and supporting portion 42; The said through hole 43 that can supply extension spring to install that on 42 surfaces, supporting portion, is arranged with.
One termination of said circular arc shoes 4 is made as flat end face 44, and another termination is made as concave arc surface 41.
The utility model shoe piece is to be used by two complete symmetries and through the extension spring 5 that is provided with respectively up and down.
Above-mentioned circular arc skeleton 45 is made in same mould once-through with supporting portion 42, and the through hole 43 direct symmetries that supply extension spring to install are located on the supporting portion 42, have improved the bulk strength of shoe piece, prolong its working life.
Claims (2)
1. motorcycle is used shoe piece; Include circular arc shoes and the brake block that is bonded in circular arc shoes convex side; Said circular arc shoes is formed by the circular arc skeleton and by the supporting portion that circular arc skeleton concave arc surface stretches out to the center; And the setting that is formed in one of circular arc skeleton and supporting portion is characterized in that: the said through hole that supplies extension spring to install that on abutment surfaces, is arranged with.
