Abstract
The utility model relates to an improvement of a brake for an automobile, particularly a shoe brake. The shoe brake comprises a brake air chamber, a brake arm connected with the brake air chamber and brake cams connected with the brake arm. The utility model is characterized in that the brake arm connected with the brake air chamber is hinged with a chain rod. The other end of the chain rod is connected with a brake separated arm which is connected with another brake cam. The utility model has the advantages of small size and simple structure. The utility model can be used on a brake for an automobile with two brake cams.
Description
Technical field
The utility model relates to a kind of improvement of automotive brake, particularly a kind of shoe brake.
Background technique
Existing shoe brake is to realize the purpose of braking by the contact friction resistance of friction plate and brake drum.In braking process, the friction and wear of friction plate and brake drum will make the variation of the area of contact of friction plate and brake drum, when area of contact reduces, will cause reducing of braking force.Patent Office of the People's Republic of China discloses by name " drum type four-ungulae eight chips do not have the point of contact break " on June 14th, 2000, notice of authorization number is the utility model patent of CN2382610Y.This application discloses a kind of drum type four-ungulae eight chips does not have the point of contact break, this break comprises brake drum, brake shoe, brake cylinder or brake cam, brake disc, stretched spring, it is characterized in that relative fixed is equipped with two brake cylinders or brake cam in brake drum, each brake shoe is to divide hoof to interconnect by bearing pin by two brakes to form; Characteristics such as the area of contact that the utlity model has eight brake blocks and brake drum keeps stablizing constant, and the braking force of break is big are fit to various vehicles and use.And existing drum-type pneumatic brake all is to drive brake arm by brake chamber, driving brake cam by brake arm rotates, realize the structure of brake, when in above-mentioned patented technology scheme, using, supporting with it with regard to needing two brake chambers corresponding and corresponding drive mechanism with brake cam, driving two brake cams rotates, and the conventional device volume is bigger, the existing device of two covers can't be installed on existing wheel braking base plate, satisfy the needs of shoe brake with two symmetrical brake cams of installing.
Summary of the invention
The purpose of this utility model provides a kind of on prior art scheme basis, employing passes to another brake cam by linkage mechanism with brake torque with a brake chamber and corresponding drive mechanism, has realized driving simultaneously the purpose that two brake cams rotate.
For realizing the purpose of this utility model, the technological scheme that adopts is: a kind of shoe brake, brake arm that comprise brake chamber, links to each other and the brake cam that links to each other with brake arm with brake chamber, it is characterized in that with brake arm that brake chamber links to each other on hinge joint one chain bar is arranged, the other end of chain bar is connected with braking and divides arm, and braking divides arm to link to each other with another brake cam.
Above-mentioned braking divides arm and connects being connected by hinge of the other end of chain bar.
Of the present utility model is to adopt the chain linkage, and the braking moment of a brake chamber is passed to two brake cams.The utility model is owing to adopt said structure, and it is little, simple in structure to have a volume, on existing vehicle structure basis, installs the purpose that a chain linkage just can realize driving simultaneously two brake cams rotations additional.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
For medium sized vehicle, because axle 8 diameter is bigger, connecting rod 7 can be made into the band arc, its objective is connecting rod 7 and axle 8 are not interfered.
Claims (2)
1, a kind of shoe brake, brake arm that comprise brake chamber, links to each other and the brake cam that links to each other with brake arm with brake chamber, it is characterized in that going up hinge joint at the brake arm (4) that links to each other with brake chamber (1) has a chain bar (7), the other end of chain bar (7) is connected with braking and divides arm (11), and braking divides arm (11) to link to each other with another brake cam.
2, shoe brake according to claim 1 is characterized in that above-mentioned braking divides arm (11) and connects being connected by hinge (9) of the other end of chain bar (7).
