Abstract
The utility model discloses a drum brake hoof block assembly of inclusionary type steel hoof block for a motor cycle, which comprises a steel hoof block weldment and a brake block. The steel hoof block weldment is formed by a brake hoof block and a framework which welded with each other, the brake hoof block is semi arch shaped on which a positioning end and a brake end are arranged. The brake end is provided with a brake pad. The brake block is attached on the outer circular arc of the brake hoof block. The braking pad is bended to form an ear protection toward the brake hoof block, which makes section of the brake pad to be C-shaped. The utility model inherits the advantages of high intensity integrally and low cost of the steel hoof block, and has the advantages of that 1, a bayonet is removed from both sides of the brake hoof block to simplify fabrication and installation; 2, the ear protection with high intensity is arranged on the sides of the brake pad for the brake hoof block to prevent distortion under stress so as to be safe for using.
Description
Technical field
The utility model relates to the motorcycle brake parts, is specifically related to inclusion type steel shoe motor bike brake shoe for drum brake block assembly.
Background technology
Existing motor bike brake shoe for drum brake block assembly is made of brake facing and brake shoe two parts, and brake facing is bonded on the brake shoe extrados.Wherein, brake shoe adopts aluminium alloy compression casting to form, and this is traditional, job operation the most widely, and there is following deficiency in it: 1, because the die casting defective often exists in potential mode, detection difficulty is big, in case will there be serious potential safety hazard in omission.2, the aluminum alloy price is constantly soaring in recent years, causes the manufacturing cost of brake shoe assembly skyrocketing.3, be die cast as high-temperature operation, labor strength is big, needs more environmental protection input and energy resource consumption simultaneously.Given this, the patent No. is that 01256585.7 Chinese utility model patent discloses a kind of Motorcycle Brake Shoe that adopts steel plate to be stamped to form, though it has overcome the defective of aluminium alloy compression casting moulding, but there is complex structure, the welding job amount is big, processing inconvenience, the new problem of difficult quality guarantee relatively is fit to the brake shoe assembly of diameter greater than 130mm.On this basis, the Chinese utility model patent that the patent No. is 03233599.7, name is called " Motorcycle Brake Shoe " discloses the Motorcycle Brake Shoe that a kind of employing steel plate of new structure is stamped to form, it is provided with bayonet socket at the brake strap two ends, skeleton is stuck on the bayonet socket to be welded again.Because skeleton need be put into the size and dimension that bayonet socket guarantees the brake shoe postwelding, thereby to the technical requirements height of brake strap and skeleton.In addition, form the bayonet socket at braking lining position, intensity difference, stressed easy deformation.
Summary of the invention
Exist processing request height, braking to serve as a contrast the deficiency of intensity difference at the Motorcycle Brake Shoe assembly that is stamped to form with steel plate now, the purpose of this utility model provides a kind of handling ease, the good inclusion type steel shoe motor bike brake shoe for drum brake block assembly of braking lining intensity.
The technical solution of the utility model is achieved in that inclusion type steel shoe motor bike brake shoe for drum brake block assembly, comprises steel shoe weldment and brake facing, and wherein steel shoe weldment is welded by brake strap and skeleton.Brake strap is semicircular arc, and its two ends are respectively positioning end and dog point, and dog point has the braking lining, and brake facing is bonded on the brake strap external arc surface.Braking lining both sides form earflap to the turnover of brake strap direction, make braking lining cross-sectional plane be " C " font.
Further improve and be: described brake strap is provided with welding connecting hole, and welding connecting hole is positioned on the middle circular arc line of brake strap.During welding, directly facing to welding connecting hole brake strap and skeleton are welded as a whole, the solder joint on the brake strap circular arc outside face is blocked by brake facing, has only very little a part of solder joint to enter brake strap circular arc inside face by welding connecting hole, thereby integral solder is effective, good looking appearance.
The utility model has kept the low advantage of bulk strength height, cost that steel shoe has, steel shoe compared to existing technology, and the utility model also has following beneficial effect:
1, the brake strap two ends do not have bayonet socket, and processing and weld-on installation are more convenient, easy.
2, the braking of brake strap lining both sides are provided with earflap, and the intensity height is difficult for when stressed producing distortion, uses safer.
3, welding effect is good, and monnolithic case is attractive in appearance.
Description of drawings
Fig. 1-the utility model structural representation;
Fig. 2-Fig. 1 right elevation;
Fig. 3-brake strap structural representation;
The Q of Fig. 4-Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, as can be seen, the utility model inclusion type steel shoe motor bike brake shoe for drum brake block assembly comprises steel shoe weldment and brake facing 1 from the figure.Wherein, steel shoe weldment is welded by brake strap 2 and skeleton 3.Brake strap 2 is semicircular arc, and its two ends are respectively positioning end 4 and dog point 5, and dog point 5 has braking lining 6, and brake facing 1 is bonded on the brake strap external arc surface 9.Braking lining 6 both sides form earflap 7 to the turnover of brake strap direction, make braking lining cross-sectional plane be " C " font, see Fig. 4.The setting of earflap structure has improved the intensity of braking lining force part, uses safer.The brake strap two ends do not have bayonet socket, and the precision of steel shoe leans on special welding anchor clamps and special welding manner to guarantee, thereby low to shape, the dimensional characteristic of brake strap and skeleton, and it is easier to process, and material is more saved.
In order to improve the steel shoe weldment presentation quality, present embodiment is provided with welding connecting hole 8 on brake strap 2, and welding connecting hole 8 is positioned on the circular arc line of brake strap 2 centres, sees Fig. 3.During welding, directly facing to welding connecting hole brake strap and skeleton are welded as a whole, no longer weld both binding sites from the inboard from brake strap circular arc outside face.Solder joint on the brake strap circular arc outside face is blocked by brake facing, have only very little a part of solder joint to enter brake strap circular arc inside face by welding connecting hole, thereby integral solder is effective, good looking appearance.
