Abstract
The utility model discloses a kind of brake shoes, for carrying out car brakeing with brake drum friction, comprise shoes body, friction lining board and elastic reset part, shoes body both sides are provided with chute, friction lining board is slidably arranged on shoes body by above-mentioned chute, shoes body one end is provided with positioning baffle, and elastic reset part one end and shoes body are connected away from positioning baffle one end and the other end is connected with away from positioning baffle one end with friction lining board; When friction lining board is against positioning baffle, on shoes body, corresponding friction lining board region is provided with multiple radiation hole, elastic reset part is in compressive state all the time, and positioning baffle flushes with the rubbing surface of friction lining board away from shoes body side, and positioning baffle is detachably arranged on shoes body.Brake shoes disclosed in the utility model, its friction lining board is changed convenient, and good heat dissipation effect.
Description
Technical field
The utility model relates to vehicle brake apparatus technical field, particularly relates to a kind of brake shoes.
Background technique
Vehicle brake is the vitals of vehicle, is the key ensureing traffic safety.Vehicle brake conventional at present comprises drum brake and disk type braker.Drum brake is primarily of component compositions such as base plate, brake drum, brake shoe, wheel cylinder, return springs.Brake drum is arranged on wheel hub, and along with wheel rotates together, when braking, wheelcylinder piston promotes brake shoe compressing brake drum, and brake drum is subject to friction eceleration, forces wheel to stop operating.Drum brake is a kind of comparatively traditional break, and because it has low price, advantages such as braking ability is good and being widely used, wherein, brake shoe is the key component of drum brake.In prior art, if Authorization Notice No. is the one brake shoes disclosed in the model utility of " CN203477135U ", adopt the mode of riveted brake shoe and friction plate to be fixed, above-mentioned means of fixation is in order to ensure riveted intensity, usual riveted holes quantity is more, adds the workload that friction plate is changed.
Model utility content
In order to solve the technical problem existed in background technique, the utility model proposes a kind of brake shoes, achieve the improvement to brake shoe iron construction, its friction lining board is changed convenient, and good heat dissipation effect.
The one brake shoes that the utility model proposes, for carrying out car brakeing with brake drum friction, comprise shoes body, friction lining board and elastic reset part, shoes body both sides are provided with chute, friction lining board is slidably arranged on shoes body by above-mentioned chute, shoes body one end is provided with positioning baffle, and elastic reset part one end and shoes body are connected away from positioning baffle one end and the other end is connected with away from positioning baffle one end with friction lining board; When friction lining board is against positioning baffle, on shoes body, corresponding friction lining board region is provided with multiple radiation hole, elastic reset part is in compressive state all the time, and positioning baffle flushes with the rubbing surface of friction lining board away from shoes body side, and positioning baffle is detachably arranged on shoes body.
Preferably, positioning baffle is less than the width of shoes body.
Preferably, radiation hole is uniformly distributed on shoes body.
Preferably, elastic reset part is spring.
Brake shoes in the utility model, in installation process, brake shoes aligns with brake drum sense of rotation by being provided with the direction of positioning baffle one end to the other end, before braking, under the effect of elastic reset part, friction lining board is positioned at the position of conflict positioning baffle, in braking process, along with the increase of frictional force between friction lining board and brake drum, friction lining board extruding elastic reset part carries out moving and the radiation hole opened on shoes body, braking vehicle in front travelling speed is larger, then friction lining board is larger to the distance away from the movement of positioning baffle one end, the radiation hole quantity opened is more, heat dispersion is stronger, simultaneously, along with the movement of friction lining board, the active force being subject to elastic reset part increases until balance each other with frictional force gradually, thus make whole brake process milder, because friction lining board is slidably arranged on shoes body by chute, positioning baffle and shoes body are for removably connecting, and therefore, positioning baffle can first be dismantled by the dismounting of friction lining board, makes friction lining board easy accessibility.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of shoes that brakes that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of shoes that brakes that the utility model proposes.
With reference to Fig. 1, in one embodiment, the one brake shoes that the utility model proposes, for carrying out car brakeing with brake drum friction, comprise shoes body 1, friction lining board 2 and elastic reset part 3, shoes body 1 both sides are provided with chute 4, friction lining board 2 is slidably arranged on shoes body 1 by above-mentioned chute 4, shoes body 1 one end is provided with positioning baffle 5, elastic reset part 3 one end is connected away from positioning baffle 5 one end with shoes body 1, and the other end is connected with away from positioning baffle 5 one end with friction lining board 2; When friction lining board 2 is against positioning baffle 5, on shoes body 1, corresponding friction lining board 2 region is provided with multiple radiation hole 6, radiation hole 6 is uniformly distributed on shoes body 1, elastic reset part 3 is in compressive state all the time, positioning baffle 5 flushes with the rubbing surface of friction lining board 2 away from shoes body 1 side, positioning baffle 5 is detachably arranged on shoes body 1, and wherein, elastic reset part 3 is spring.
In the above-described embodiments, in installation process, brake shoes aligns with brake drum sense of rotation by being provided with the direction of positioning baffle 5 one end to the other end, before braking, under the effect of elastic reset part 3, friction lining board 2 is positioned at the position of conflict positioning baffle 5, in braking process, along with the increase of frictional force between friction lining board 2 and brake drum, friction lining board 2 extrudes elastic reset part 3 and carries out moving and open the radiation hole 6 on shoes body 1, braking vehicle in front travelling speed is larger, then friction lining board 2 is larger to the distance away from positioning baffle 5 one end movement, radiation hole 6 quantity opened is more, heat dispersion is stronger, simultaneously, along with the movement of friction lining board 2, the active force being subject to elastic reset part 3 increases until balance each other with frictional force gradually, thus make whole brake process milder, because friction lining board 2 is slidably arranged on shoes body 1 by chute 4, positioning baffle 5 and shoes body 1 are for removably connecting, and therefore, positioning baffle 5 can first be dismantled by the dismounting of friction lining board 2, makes friction lining board 2 easy accessibility.
In the technological scheme improved further, positioning baffle 5 is less than the width of shoes body 1, is above-mentionedly designed with the dismounting be beneficial to as positioning baffle 5 and provides more sufficient space, and can save material.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
