Abstract
The utility model relates to an automobile the stopper. A novel brake assembly behind car, includes brake drum and two brake shoes, the wherein one end of two brake shoes all articulated with the brake drum, the other end of two brake shoes is provided with two -way brake hydraulic cylinder each other, fixed setting of two -way brake hydraulic cylinder be in the brake drum on, the outside of two brake shoes all set up friction lining, the inboard brake drum of brake shoe on still be provided with the locating pin, two brake drums between be provided with return spring, the tip that is connected with two brake shoes of two -way brake hydraulic cylinder still be connected with an attenuator. The utility model has the advantages of reasonable design, be three -section structure through designing friction lining, and thickness is reduced to both ends by the middle part to make and to accomplish the purpose that the multistage was applied the brake simultaneously at the braking initial stage, avoid appearing local excessive wear.
Description
Technical field
The utility model relates to a kind of automotive brake, is specifically related to a kind of new automobile rear brake assembly.
Background technique
Drum brake is a kind of comparatively traditional break, and because it has low price, the advantages such as braking ability is good are still widely used.Traditional drum brake generally comprises base plate, two panels brake shoe, the compositions such as brake fluid cylinder pressure and Returnning spring.Drum brake, when braking operation, promotes brake shoe by brake fluid cylinder pressure and brake shoe is expanded outwardly, and compressing support is risen inside brake hub, the friction facing outside brake hub internal surface and brake shoe is produced and rubs, force wheel to stop operating.The friction facing of the outer round surface of traditional drum brake brake shoe is all uniform thickness, less in the contact of braking initial stage, cause concentrated wear serious, even brake failure, in addition due to break too rigidity in course of action, cause the working life of break shorter.
Model utility content
For above-mentioned Problems existing and deficiency, the utility model provides a kind of reasonable in design, and braking ability is good, the new automobile rear brake assembly of long service life.
For solving the problem, the technological scheme taked is:
A kind of new automobile rear brake assembly, comprise brake drum and brake shoe, wherein one end of two described brake shoes is all hinged with brake drum, the other end of two brake shoes is provided with bi-directional braking oil hydraulic cylinder each other, described bi-directional braking oil hydraulic cylinder is fixedly installed on described brake drum, the outside of two described brake shoes all arranges friction facing, described friction facing comprises the epimere friction facing of trisection, stage casing friction facing and hypomere friction facing, the arranged outside of described brake shoe has the heavy stand corresponding with friction facing, brake drum inside described brake shoe is also provided with locating stud, described brake shoe is provided with the locating slot corresponding with locating stud, return spring is provided with between two described hoof processed, the described end being connected with two brake shoes of bi-directional braking oil hydraulic cylinder is also connected with a damper.
The thickness of the epimere friction facing on described brake shoe, stage casing friction facing and hypomere friction facing all reduces from middle part gradually to two ends.
Adopt technique scheme, acquired beneficial effect is:
The utility model reasonable in design, the utility model is by being designed to three stage structure by friction facing, and thickness is reduced to two ends by middle part, thus make can complete at the braking initial stage object that multistage brakes simultaneously, avoid occurring that local excessive is worn and torn, the centrifugation of each retaining segment can also be played, guarantee the long service life of break, the utility model is also by arranging damper, thus make to alleviate the rigid collision of vibration that brake cylinder is subject to and break in braking process, thus substantially increase the working life of break.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Sequence number in figure: 1 be brake drum, 2 be brake shoe, 3 be bi-directional braking oil hydraulic cylinder, 4 be epimere friction facing, 5 be stage casing friction facing, 6 be hypomere friction facing, 7 be heavy stand, 8 be locating stud, 9 be return spring, 10 for damper.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described, but the utility model is not limited to these embodiments.
See Fig. 1, a kind of new automobile rear brake assembly of the present embodiment, comprise brake drum 1 and brake shoe 2, wherein one end of two described brake shoes 2 is all hinged with brake drum 1, the other end of two brake shoes 2 is provided with bi-directional braking oil hydraulic cylinder 3 each other, described bi-directional braking oil hydraulic cylinder 3 is fixedly installed on described brake drum 1, the outside of two described brake shoes 2 all arranges friction facing, described friction facing comprises the epimere friction facing 4 of trisection, stage casing friction facing 5 and hypomere friction facing 6, the arranged outside of described brake shoe 2 has the heavy stand 7 corresponding with friction facing, brake drum inside described brake shoe 2 is also provided with locating stud 8, described brake shoe 2 is provided with the locating slot corresponding with locating stud, return spring 9 is provided with between two described brake shoes 2, the described end being connected with two brake shoes 2 of bi-directional braking oil hydraulic cylinder 3 is also connected with a damper 10, epimere friction facing 4 on described brake shoe, the thickness of stage casing friction facing 5 and hypomere friction facing 6 all reduces from middle part gradually to two ends.
The utility model reasonable in design, the utility model is by being designed to three stage structure by friction facing, and thickness is reduced to two ends by middle part, thus make can complete at the braking initial stage object that multistage brakes simultaneously, avoid occurring that local excessive is worn and torn, the centrifugation of each retaining segment can also be played, guarantee the long service life of break, the utility model is also by arranging damper, thus make to alleviate the rigid collision of vibration that brake cylinder is subject to and break in braking process, thus substantially increase the working life of break.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art also can make multiple change accordingly, but to be anyly equal to the utility model or similar change all should be encompassed in the scope of the utility model claim.
Claims (2)
