Abstract
The utility model discloses a novel drum brake. The novel drum brake mainly comprises a shell, brake pads, a rocker wheel and reset springs. The rocker wheel is arranged on the shell, the reset springs are arranged in the brake pads, and the brake pads are arranged on the shell through the reset springs; the drum brake is provided with at least three identical brake pads, a movable rotor is arranged in the adjacent ends of every two adjacent brake pads, and the movable rotors make contact with protruding parts on the rocker wheel. According to the novel drum brake, the span between the two ends of each brake pad is reduced, deformation of the brake pads in the braking process is effectively reduced, the service life of the brake pads is prolonged, the drum brake is sensitive in braking, abrasion to single sides of the brake pads is basically eradicated, and the safety performance of a vehicle is further improved.
Description
Technical field
The utility model belongs to vehicle brake technology field, particularly the hub of the vehicle structure of stopping.
Background technique
The history in hub formula brake applications existing nearly century on vehicle, due to its reliability and powerful braking force, is still configured in many vehicles as heavy goods vehicle, motorcycle, electric motor car the brake of hub formula now.The brake of hub formula is will be installed in brake hub and have brake block toward extrapolation by hydraulic pressure, makes brake block and the inner face generation friction of the brake hub along with vehicle wheel rotation produce the effect of skidding.
In existing vehicle hub is stopped, be to utilize two symmetrical brake shoes to expand outwardly contact with brake hub that producing rubs realizes skidding mostly, as CN102322488A patent discloses a kind of Novel drum brake, comprise shell, be located at a pair of brake shoes in shell, be connected to this to the reposition element between brake shoes and brake arm assembly, this to one end rotating position of brake shoes in the enclosure, this is to being provided with the brake wheel being rotated by brake arm Component driver between the end gap of the brake shoes the other end, between the brake shoes end face of brake wheel and both sides, each butt has roller, brake wheel is provided with the limit structure that prevents roller dislocation.
Existing this hub is stopped and is had following defect: in braking process, between the two end part of each brake shoes, span is large, brake shoes is expanding outwardly in process, and brake shoes itself easily produces distortion, causes the brake shoes life-span short, braking effect is insensitive, in addition, the hub of this structure is stopped and in braking process, is prone to brake shoes uneven wear phenomenon, and braking effect is poor, braking distance increases, and easily causes traffic accident.
Model utility content
The problem on deformation of brake block itself when solving hub braking in prior art, the utility model provides a kind of novel hub to stop, and can reduce the distortion of brake block, improve the working life of brake block, promote skidding effect and sensitivity, meanwhile, also can reduce brake block uneven wear phenomenon.
The technical solution of the utility model is as described below:
A kind of novel hub is stopped, mainly be made up of housing, brake block, rocking arm wheel, Returnning spring; rocking arm wheel is arranged on housing; in brake block, be provided with Returnning spring; brake block is arranged on housing by Returnning spring; described hub is stopped and is at least provided with three identical brake blocks, is provided with movable rotor in the inside of every two brake block abutting ends, movable rotor contacts with the lug boss on rocking arm wheel.
In the utility model, take turns rotation by rocking arm, order about movable rotor and outwards move, each brake block expands outwardly to contact with brake hub and produces friction realization braking.
Advantage of the present utility model and beneficial effect:
Feature of the present utility model is conventional two-piece type brake block to change into more than three, thereby reduce the span between each brake block two end part, reduced the distortion of brake block in braking process itself, thereby improved the life-span of brake block, in addition, the utility model also tool have the following advantages:
1, skidding effect is sensitive, shortens car brakeing reflecting time more than 15% compared with conventional wheel hub;
2, substantially stop brake block uneven wear phenomenon, further promoted the Safety performance of vehicle.
3, simple in structure, production, easy for installation, and replacement cost is low.
Brief description of the drawings
Fig. 1 be hub of the present utility model stop analyse and observe (signal) figure,
In figure: 1-brake block, 2-housing, 3-rocking arm wheel, 4-Returnning spring, 5-movable rotor, 6-lug boss.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but the scope that should at this point not be interpreted as theme described in the utility model only limits to following embodiment, do not departing from the above-mentioned technological thought situation of the utility model, all various amendments, replacement and changes of making according to ordinary skill knowledge and customary means, include in scope of the present utility model.
As shown in Figure 1, a kind of novel hub is stopped, mainly be made up of housing 2, brake block 1, rocking arm wheel 3, Returnning spring 4; rocking arm wheel 3 is arranged on housing 2; in brake block 1, be provided with Returnning spring 4, brake block 1 is arranged on housing 2 by Returnning spring 4, and described hub is stopped and is provided with three identical brake blocks 1; inside at every two brake block 1 abutting ends is provided with movable rotor 5, movable rotor 5 contacts with the lug boss 6 on rocking arm wheel 3.
In the utility model, for reducing the distortion of brake block 1 own, Hoist braking braking effect, the working life of prolongation brake block, the brake block 1 that hub is stopped can be set to four, five or more according to the stop size of size and braking force of hub, but cost performance the best while being set to three or four.
