The utility model is characterized in that a piston rod on a brake cylinder is connected with the brake arm. The brake arm 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 brake can adopt two pneumatic cylinders or hydraulic cylinders to respectively drive two brake cams to rotate. The utility model has the characteristics of small size, simple structure and high reliability. The utility model is suitable for the 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 that utilizes cylinder or oil hydraulic cylinder.
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, by cylinder or oil hydraulic cylinder braking moment is passed to two brake cams, realized driving simultaneously two brake cams and rotated a kind of shoe brake that utilizes cylinder or oil hydraulic cylinder that reaches the braking purpose.
For realizing the purpose of this utility model, the technological scheme that adopts is: a kind of shoe brake that utilizes cylinder or oil hydraulic cylinder, comprise break, brake arm and link to each other with brake arm be installed in brake cam in the break, it is characterized in that the piston rod on brake cylinder is connected with brake arm, hinge joint has a chain bar on brake arm, 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.
Above-mentioned braking divides arm and being connected by hinge of piston rod to connect.
A kind of fluid power shoe brake, comprise break, brake arm and link to each other with brake arm be installed in brake cam in the break, it is characterized in that being connected with two brake arms respectively at the piston rods of two brakings on the oil cylinders, two brake arms link to each other with two brake cams in the break respectively.
Above-mentioned brake arm connected with being connected by hinge of piston rod.
The utility model is owing to adopt oil cylinder or cylinder, the device that original drive brake cam is rotated reduces, the braking moment of an oil cylinder or cylinder can be passed to two brake cams simultaneously or directly adopt two oil cylinders or two brake cams rotations of cylinder drive, improved the reliability of braking on the one hand, it is little, simple in structure to have volume simultaneously, on existing vehicle structure basis, do very little change and just can realize driving simultaneously the purpose that two brake cams rotate.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 1 a structural representation.
Embodiment
Embodiment 1:
As shown in Figure 1, braking moment is that the piston rod 2 by cylinder or oil hydraulic cylinder 1 passes to braking force the brake arm 4 that is connected by hinge 3 with piston rod 2, brake arm 4 links to each other with the brake camshaft 5 of break 6 middle and upper parts, hinge joint has a connecting rod 7 on brake arm 4, the other end of connecting rod 7 divides arm 11 to link to each other by hinge 9 with braking, and braking divides arm to link to each other with the brake camshaft 10 of break middle and lower part.When braking, step on the automotive brake pedal, the piston rod 2 of cylinder or oil hydraulic cylinder 1 is protruding, promotes brake arm 4 and rotates in the counterclockwise direction, under the effect of connecting rod 7, drives braking and divides arm 11 to rotate in the counterclockwise direction simultaneously.Because two brake cams up and down divide arm 11 to link to each other with brake arm 4 and braking respectively by coupled camshaft 5,10, when brake arm 4 and the rotation of braking branch arm, two brake cams that drive in the break 6 are rotated, brake shoe is opened, reach the braking purpose.
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.
Embodiment 2:
As shown in Figure 2, last brake arm 4 links to each other with the piston rod 2 of upper cylinder or oil hydraulic cylinder 1 by hinge 3, following brake arm 11 links to each other with the piston rod of lower cylinder or oil hydraulic cylinder 12 by hinge 9, when braking, step on the automotive brake pedal, the piston rod 2 of upper and lower air cylinders or oil hydraulic cylinder is protruding, promotes brake arm 4 and rotates in the counterclockwise direction, and brake arm 11 rotates along clockwise direction.Because two brake cams up and down divide arm 11 to link to each other with brake arm 4 and braking by coupled camshaft 5 respectively with 10, when brake arm 4 and brake arm 11 rotations, two brake cams that drive in the break 6 are rotated, brake shoe is opened, reach the braking purpose.
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.
