Description
Technical field
It the utility model is related to a kind of brake gear of automobile.
Background technology
Drum brake and disk brake are to use disc type system on the two kinds of automotive brakes used, car at present
Dynamic device is more common, and it is the complicated of drum brake to influence the main reason for drum brake widely uses, part comparison
More, maintenance is inconvenient.
Utility model content
In order to solve problem present in background technology, the utility model provides a kind of automobile drum brake, the system
Dynamic utensil has simple in construction, maintains the advantages that facilitating.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
A kind of automobile drum brake, including circular chassis, the center on chassis are provided with rotating shaft, and rotating shaft can be the bottom of with respect to
Disk is freely rotated, and stator is fixed with rotating shaft, and stator rotates together with rotating shaft, is respectively arranged with positioned at the corner of stator
One stay bolt, brake rim are fixed together by stay bolt and rotating shaft；The both sides up and down of rotating shaft are provided with the brake of two arcs
Car boots, brake boots one end of two arcs is hinged, and other end is linked together by hydraulic jack, and hydraulic jack pushes away
Dynamic two brake boots are also associated with spring between the middle part for the boots that brake, consolidated on the outer wall for the boots that brake with respect to pin joint disengaging movement
Surely there is brake block, brake rim has annular sidewall, and annular sidewall covers on the outside of brake block.
The provided circumferentially about of the chassis has flange.
Brake rim center has circular hole, and rotating shaft is stretched out from circular hole.
The beneficial effects of the utility model are：Structure is simpler, and cost is lower, and maintenance is more convenient, is adapted to automobile
Use.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the decomposing schematic representation of drum brake described in the utility model；
Embodiment
Explanation and embodiment are further described to the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in figure 1, a kind of automobile drum brake, including circular chassis 1, the provided circumferentially about of chassis 1 have flange,
The center on chassis 1 is provided with rotating shaft 6, and rotating shaft 6 can freely be rotated relative to chassis 1, and stator 7, stator are fixed with rotating shaft 6
7 rotate together with rotating shaft 6, are respectively arranged with a stay bolt positioned at the corner of stator 7, brake rim 4 is fixed with stay bolt,
The center of brake rim 4 has circular hole, and rotating shaft 6 is stretched out from circular hole, and brake rim is fixed together by stay bolt and rotating shaft 6.
The both sides up and down of rotating shaft 6 are provided with the brake boots 2 of two arcs, and one end of brake boots 2 of two arcs is hinged on one
Rise, other end is linked together by hydraulic jack 5, and hydraulic jack 5 promotes two brake boots 2 with respect to pin joint separation fortune
It is dynamic, spring 8 is also associated between the middle part for the boots 2 that brake, brake block 3 is fixed with the outer wall for the boots 2 that brake.Brake rim has annular
Side wall, annular sidewall cover on the outside of brake block 3.
During brake, hydraulic jack 5 promotes brake boots 2 with respect to pin joint disengaging movement, the brake block at this time to brake on boots 2
3 hold out against the madial wall of brake rim 4, in the presence of frictional force, are fixed on the wheel on the outside of brake rim and reduce speed now.Cancel brake
When, two brake boots 2 reset under the draw of spring 8, and brake block 3 leaves the madial wall of brake rim 4, and at this time brake takes
Disappear.
Relatively conventional drum brakes, drum-like brake structure described in the utility model is simpler, and cost is lower, maintenance
Maintain more convenient, the use of suitable automobile.
It will be recognized by those skilled in the art, can be to above-mentioned on the premise of without departing from protection scope of the present invention
Embodiment carries out various modifications, change and combination, and thinks that this modification, change and combination are the models in originality thought
Within enclosing.
