Abstract
The utility model relates to novel automobile fittings for the simple improvement of the brake shoe in the existing brake for automobile, which changes the concentricity of the brake shoe and the brake drum, increases the contact area between the brake drum and the brake shoe friction plate, and increases the brake force of the automobile. When the automobile braking device is used, the gap between the brake drum and the brake shoe friction plate has no decisive effect on the performance of the automobile brake, which saves time and work in the routine regulation of the gap size to maintain good brake performance by automobile maintenance personnel. After the device is applied to a plurality of types of automobiles, the effect is comparatively ideal and completely conforms to the requirement of the automobile brake performance by the Ministry of Communication after tested in the automobile testing plant.
Description
The utility model belongs to automotive field.
The car side brake of passenger-cargo automobile that modern age is commonly used all is an inner expanding brake, kills in the car process, and brake shoe lining contacts with brake wheel and produces friction force, reaches car purpose extremely.This car device that kills, the quality of technical performance is except the assembly performance that depends on device proper, also need the automotive servicing personnel in time to adjust gap between brake wheel and the brake shoe lining, during excessive clearance, can cause that braking is slow, the braking force deficiency, brake efficiency is low, and stopping distance increases, when too small, cause sticking of brakes as the gap, the abrasion aggravation, the drg heating, deceleration and stopping performance degenerates etc., and this just depends on automotive servicing personnel's ability and experience, has certain eventuality.
The purpose of this utility model is a kind of later-model car brake of design, makes the gap length between brake wheel and the brake shoe lining, does not play a decisive role for killing car performance quality.In addition, this novel car device has extremely strengthened the contact surface between brake wheel and the friction lining, and braking force is strengthened, and braking is sensitive, the brake efficiency height, and stopping distance is short.
Fig. 1 is a schematic diagram of the present utility model.
Below in conjunction with accompanying drawing, introduce in detail content of the present utility model. The utility model specific implementation is the bottom at brake-shoe, a cutter is cut in place near fore brake backing pin 8 sideling, brake-shoe is divided into brake-shoe main leaf 6 and small pieces 7 two parts, wherein the head end of brake-shoe main leaf 6 is connected with front brake cylinder 1, tail end is relative with an end of brake-shoe small pieces 7, keep certain interval between the two ends, the other end of small pieces 7 is fixedly connected by fore brake backing pin 8 and rear braking subpump. During automobile brake, step on brake pedal, master cylinder (not shown in FIG.) with oil pressure to brake cylinder 1, and promotion brake-shoe main leaf 6, its top is outwards dilated, and press to brake drum 5, this moment, brake-shoe was divided into two power, a component that is perpendicular to brake drum to the thrust of brake drum, another be along with wheel rotate forward and produce to sliding force, this power is pressed to brake shoe anchor 8 along brake-shoe main leaf 6, because at breach of brake-shoe undercut, at this moment, brake-shoe main leaf 6 will glide along drum surface, the bottom of brake-shoe is also expanded outwardly, and whole friction plate contacts with the braking drum surface, produces bigger brake force. After loosening the brake, extension spring 3 returns to original original position with brake-shoe, and vehicle recovers normally to travel. The head and the tail of adjacent two brake-shoe main leaves are held respectively at the two ends of extension spring.
The utility model has been used for the automobile of several different models, and effect is satisfied.The test of experience depot meets the requirement of Ministry of Communication to vehicle braking performances fully, and the conventional car device that kills of braking-force ratio increases by 20 kilograms.In addition, the conventional car device that kills needs the gap between brake wheel of an adjustment in month and the friction face, the regulation that just can meet Ministry of Communication, behind the utility model, vehicle kill that car is functional to have kept the several months constant, the regular adjusting play size of taking a lot of work when having saved the vehicle maintenance and repair personal services.
Claims (1)
1, a kind of floating type car device of forming by brake wheel, friction lining, brake shoe brake cheek, brake shoe anchor and extension spring that kills, it is characterized in that brake shoe brake cheek cuts sth. askew into brake shoe brake cheek main leaf and small pieces two parts, wherein main leaf one end and brake cylinder link, the other end is relative with an end of small pieces, stay a gap between the two ends, the other end of small pieces links by brake shoe anchor and another brake cylinder, and the head and the tail of adjacent two brake shoe brake cheek main leaves are held at the two ends of extension spring respectively.
