Abstract
The utility model discloses a rear brake bottom plate of a shoe brake, which aims at solving problems of being in a chatter and a locking, unreliable in braking and the like in the existing shoe brake. The rear brake bottom plate of the shoe brake comprises a bottom plate body. A protruding block provided with a connecting through hole and integrated with the bottom plate is arranged on a periphery of a central shaft hole of the bottom plate. A shoe fixing part integrated with the bottom plate is also arranged on the bottom plate, two through holes used for fixing the shoe are arranged on the shoe fixing part, and a guide groove is formed by a gap between the two through holes. In addition, a shaft sleeve base is arranged on the bottom plate, shaft sleeve holes matched with the two through holes of the shoe fixing part are arranged on the shaft sleeve base, and the sleeve base penetrates though the shoe fixing part and is fixed on the bottom plate through rivets. The rear brake bottom plate of the shoe brake is simple in structure and reliable in braking, and improves safety in driving.
Description
Technical field
The utility model designs a kind of shoe brake, is specifically related to the back braking bottom board of shoe brake.
Background technique
Traditional shoe brake main with component compositions such as braking bottom board, brake drum, braking shoes, wheel cylinder or camshaft, return spring, locating stud.Be the parts that rotate with wheel, it is to be made by the cast iron of certain component, and shape is like the circle drum type.When braking, wheelcylinder piston or camshaft rotate the roller end that promotes the braking shoes and outwards stretch, compressing outside hung brake drum, and the inwall of brake drum and friction plate friction progressively make vehicle deceleration, force wheel to stop operating.
The shoe brake of said structure, be symmetricly set on the left side on the braking bottom board, right braking hoof iron, it is circular with the mounting hole that braking bottom board axially is connected, camshaft rotation promotion braking shoes is installed as the center of circle with it and outwards stretches, therefore, the stretching, extension front end of braking shoes is the contact brake drum earlier, with the brake drum friction, after the band brake shoes stretched the friction disc wear major part of front end, the rear end, location of braking shoes is the very little part of wearing and tearing just, and friction differs, friction plate also will be changed: cause very big waste to the user like this, braking shoes one end of shoe brake is defined swing, and suddenly in a flash, braking shoes one end is forced the compressing brake drum, " flutter " and phenomenons such as " lockings " can appear, it is unreliable to brake, and it is dangerous to drive a vehicle, and takes uncomfortable.
The model utility content
The purpose of this utility model is to solve the appeal defective, and a kind of structure improved shoe type braking bottom board is provided, and it is even that it has rubbing surface, prolong the working life of friction plate and brake shoe and braking bottom board, brake more reliably, Braking efficiency is higher, improve traffic safety, make the driving car more comfortable.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
Braking bottom board behind a kind of shoe brake comprises the base plate body, base plate body central shaft hole outer periphery also have one with the integrated protruding block of base plate, have connecting through hole on the protruding block; Also be provided with on the base plate and the integrated shoes fixed component of base plate, described shoes fixed component is provided with fixedly two through holes of shoes, and the gap between the two through hole constitutes guiding groove.
Further, braking bottom board also is provided with a sleeve block behind the shoe brake, and described sleeve block is provided with the axle sleeve hole that matches with the two through hole of shoes fixed component, and sleeve block inserts in the shoes fixed component and fixedly is fixed on the base plate by rivet.
More specifically, described sleeve block is that a kind of alloy material is made, and alloy material is the low-carbon (LC) Buddha's warrior attendant.
The beneficial effect of braking bottom board is behind the shoe brake described in the utility model: the braking shoes is launched fully, the friction plate and the brake drum comprehensive engagement of braking shoes, make rubbing surface even, contact is big, thereby braking is reliable, improves traffic safety, have again, braking is stable, avoids brake noise, break return steadily rapid, improved greatly drive, travelling comfort by bus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with Figure of description embodiment of the present utility model is done detailed description.Obviously, described embodiment only is a part of embodiment of the present utility model, and other embodiment that those skilled in the art is obtained under the prerequisite of not paying creative work belongs to protection domain of the present utility model.
Braking bottom board comprises base plate body 1 behind the shoe brake of the present utility model as shown in Figure 1, 2, base plate center axis hole 11 outer periphery also have one with base plate 1 integrated protruding block 2, have connecting through hole 21 on the protruding block 2; Also be provided with on the base plate 1 and base plate 1 integrated shoes fixed component 3, described shoes fixed component 3 is provided with fixedly two through holes 31,32 of shoes, and the gap between the two through hole constitutes guiding groove 33; Braking bottom board also is provided with a sleeve block 4 behind the shoe brake, described sleeve block 4 is provided with the axle sleeve hole 41,42 that matches with two logical 31,32 holes of shoes fixed component 3, sleeve block 4 inserts in the shoes fixed component 3, and sleeve block is fixed on the base plate 1 with 3 rivets.
As required, axle sleeve can be a kind of alloy material, and its alloy material is a kind of low-carbon (LC) Buddha's warrior attendant.
It should be noted that at last: above embodiment only is used to illustrate the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
