Abstract
The utility model provides a novel brake shoe used for an electric vehicle, and relates to the field of electric vehicle parts. The outer wall of the arc shoe (1) is provided with a brake block (2), the middle portion of the arc shoe (1) is provided with a through hole (4), two sides of the through hole (4) are provided with supporting ribs (3), a buffering block (6) is embedded into the through hole (4), and the upper end and the lower end of the arc shoe (1) are respectively provided with a tension spring installation hole (5). The novel brake shoe is simple in structure, simple in manufacturing process and low in cost, has a certain buffering effect, can improve safety during braking, and can lower abrasion, and service life is prolonged.
Description
Technical field:
The utility model relates to electric accessory motor field, is specifically related to the automobile-used shoe piece of a kind of electric.
Background technique:
Brake shoe refers to and is subject to the action quantity of brake cam or push rod and is pushed to outer expansion compacting brake and heaves the accessory of braking action, is installed on brake drum, and be one of breaking piece crucial in braking system.Brake shoe shape is as semilune, and while touching on the brake, two semi-moon shaped brake shoes, just lower outside of the effect of wheel cylinder, are propped up the rubbing inwall of brake drum of brake shoe and played the effect of slowing down or stopping.
Existing shoe piece is all hard material, in use without any buffering, and accident susceptibility during emergency brake, and larger for the injury of shoe piece during emergency brake, wearing and tearing are large, the working life of having reduced shoe piece.
Model utility content:
The purpose of this utility model is to provide the automobile-used shoe piece of a kind of electric, and it is simple in structure, and preparation process is simple, and cost is low, has certain cushioning effect, the safety in the time of improving brake, and can reduce wearing and tearing, increase the service life.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises circular arc hoof piece 1, brake block 2, ribs 3, through hole 4, extension spring mounting hole 5, buffer stopper 6; The outer wall of arc hoof piece 1 is provided with brake block 2, and the centre of arc hoof piece 1 is provided with through hole 4, and the both sides of through hole 4 are provided with ribs 3, and buffer stopper 6 is embedded in through hole 4, and the upper and lower end of arc hoof piece 1 is equipped with extension spring mounting hole 5.
The two side of described buffer stopper 6 is fixedly connected with the madial wall of through hole 4, and buffer stopper 6 can be changed, and has reduced user cost.
The inwall of described extension spring mounting hole 5 is provided with wearing layer, can extend the working life of hoof piece.
During the utility model operation, two symmetrical circular arc hoof pieces 1 were combined by extension spring mounting hole 5 and coordinating of extension spring, while touching on the brake, two circular arc hoof pieces 1 are just lower outside of the effect of wheel cylinder, prop up the rubbing inwall of brake drum of brake block 2, the certain tension force of buffer stopper 6 available buffers in emergency brake process, avoid tire to overturn because of emergency brake, improved safety coefficient.
The beneficial effects of the utility model: simple in structure, preparation process is simple, and cost is low, have certain cushioning effect, the safety in the time of improving brake, and can reduce wearing and tearing, increase the service life.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the use phase diagram of model utility.
Embodiment:
See figures.1.and.2, this embodiment by the following technical solutions: it comprises circular arc hoof piece 1, brake block 2, ribs 3, through hole 4, extension spring mounting hole 5, buffer stopper 6; The outer wall of arc hoof piece 1 is provided with brake block 2, and the centre of arc hoof piece 1 is provided with through hole 4, and the both sides of through hole 4 are provided with ribs 3, and buffer stopper 6 is embedded in through hole 4, and the upper and lower end of arc hoof piece 1 is equipped with extension spring mounting hole 5.
The two side of described buffer stopper 6 is fixedly connected with the madial wall of through hole 4, and buffer stopper 6 can be changed, and has reduced user cost.
The inwall of described extension spring mounting hole 5 is provided with wearing layer, can extend the working life of hoof piece.
During the operation of this embodiment, two symmetrical circular arc hoof pieces 1 were combined by extension spring mounting hole 5 and coordinating of extension spring, while touching on the brake, two circular arc hoof pieces 1 are just lower outside of the effect of wheel cylinder, prop up the rubbing inwall of brake drum of brake block 2, the certain tension force of buffer stopper 6 available buffers in emergency brake process, avoid tire to overturn because of emergency brake, improved safety coefficient.
This embodiment is simple in structure, and preparation process is simple, and cost is low, has certain cushioning effect, the safety in the time of improving brake, and can reduce wearing and tearing, increase the service life.
