Description
Technical field
The utility model relates to a kind of brake hub, especially a kind of electric vehicle brake center hub.
Background technique
Brake hub is the significant components of automotive brake, and in automobile brake, piston applies pressure to two shoe brakes,
It is set to be adjacent to braking hub wall, to generate friction to brake to automobile.
At present brake hub exist the most major problem is that, brake hub generate friction it is heated after diameter will increase, to make
It is increased at the stroke of brake pedal, is easy to happen brake response situation not as expected.And solve the problems, such as that this is most important
Two o'clock, first is that how to limit the deformation generated after brake hub is heated（Diameter increases）, second is that how to improve the thermal diffusivity of brake hub
Energy.
Summary of the invention
To solve deficiency existing for background technique, the utility model provides a kind of electric vehicle brake center hub.
Realize above-mentioned purpose, the utility model takes following technical proposals：A kind of electric vehicle brake center hub, including
Brake hub ontology, the brake hub ontology shape are the closed cylindrical shape of the open at one end other end, brake hub ontology closed end
Center is equipped with installation shaft sleeve, and the electric vehicle brake center hub further includes reinforcing ring, brake hub ontology opening end face
Multiple arcs cavity groove, brake hub outer body surface and each arc cavity groove pair are angularly recessed with along its circumferencial direction
At least one heat extraction pin hole should be through with, the reinforcing ring is fixedly connected with brake hub ontology opening end face, and reinforcing ring with
Brake hub ontology open end faces nearly side surface protrusion and is provided with multiple arcs plug, the multiple arcs plug with it is multiple
Arc cavity groove is arranged in a one-to-one correspondence.
Compared with prior art, the utility model has the beneficial effects that：The utility model is in brake hub ontology opening end face
It is recessed with multiple arcs cavity groove, brake hub outer body surface is corresponding with each arc cavity groove to be through with heat extraction pin hole, adds and adds
While strong ring limitation brake hub ontology open end is thermally deformed, the arc cavity groove of the arc plug of reinforcing ring to brake hub ontology
It is blocked, so that arc cavity groove is only passed through heat extraction pin hole and be connected to outside, since arc cavity groove is hollow structure, braking can be reduced
The amplitude of deformation after hub ontology is heated, while internal heat-conducting area is increased, it is heated inside arc cavity groove to be pressurized from heat extraction pin hole
Discharge, the gear teeth protrusion on brake hub outer body surface increase outside table heat dissipation area, and comprehensive to improve heat dissipation performance, structure is simple
Effectively, be conducive to be popularized.
