Poor performance can assemble a large amount of heat in braking process.Brake block and wheel hub are easier to occur extremely complex under the influence of high temperature
Deformation, easy to produce fading of brake and flutter phenomenon, braking efficiency is caused to decline.Existing automobile drum brake heat radiation energy
Power is poor and can not achieve from cooling, and existing automotive hub cannot meet the needs of people gradually, therefore we are to this
Improvement is made, proposes a kind of self-cooled automobile drum brake.
Invention content
It is poor and can not achieve self cooled lack to solve automobile drum brake heat-sinking capability of the existing technology
It falls into, the utility model provides a kind of self-cooled automobile drum brake.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of self-cooled automobile drum brake of the utility model, including wheel rim and brake drum, the outside of the brake drum
By being fixedly connected on the inside of several spokes and wheel rim, arc cooling is installed between adjacent two spokes
The inner wall of case, the wheel rim is uniformly provided with several pieces of heat-conducting blocks, and the middle part of the brake drum is equipped with for matched with axle
The avris of inner ring hole, the brake drum is uniformly provided with several air inlet holes, and the outer ring of the brake drum offers and air inlet hole
The venthole communicated.
Further, the outer ring on the inside of each arc cooler bin offers inlet opening.
Further, the inner ring on the inside of the arc cooler bin is fixedly installed arc-shaped fin-shaped thermally conductive sheet.
Further, one end of the heat-conducting block is fixed with strip fin.
Further, the outer wall of the brake drum is coated with for etch-proof skin of paint.
Compared with prior art, the utility model has the advantages that：This kind of self-cooled automobile drum brake leads to
The air inlet hole and exhaust vent being provided on brake drum are crossed, the wind driven when running car is entered by air inlet hole in brake drum,
Simultaneously radiate to brake drum, the wind after heat exchange by exhaust vent discharge, with realize wheel hub from the type of cooling, by being equipped with
Arc cooler bin, inlet opening and fin-shaped thermally conductive sheet, staff are supplemented using inlet opening toward the inside of arc cooler bin suitable
Coolant liquid, when running car, the heat that exhaust vent is discharged in gas can be conducted to arc cooler bin, arc by fin-shaped thermally conductive sheet
The heat that coolant liquid in shape cooler bin conducts fin-shaped thermally conductive sheet cools down, and improves the radiating efficiency of brake drum, simultaneously
Heat-conducting block is effectively radiated the heat generated in tire motion process by strip fin, improves automobile drum type brake
The heat dissipation performance of device.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-2, a kind of self-cooled automobile drum brake, including wheel rim 1 and brake drum 5, the outside of brake drum 5
It is fixedly connected with the inside of wheel rim 1 by several spokes 2, arc cooling is installed between adjacent two spokes 2
Case 9, the inner wall of wheel rim 1 are uniformly provided with several pieces of heat-conducting blocks 3, the middle part of brake drum 5 be equipped with for the matched inner ring of axle
The avris in hole 6, brake drum 5 is uniformly provided with several air inlet holes 7, and the outer ring of brake drum 5 is offered to be gone out with what air inlet hole 7 communicated
Stomata 8.
Wherein, the outer ring of 9 inside of each arc cooler bin offers inlet opening 10, is convenient for work people by inlet opening 10
Member cools down to 9 inside to arc and supplements coolant liquid, the heat that arc cooler bin 9 can will generate in 5 motion process of brake drum
It is effectively radiated by fin-shaped thermally conductive sheet 11.
Wherein, the inner ring of 9 inside of arc cooler bin is fixedly installed arc-shaped fin-shaped thermally conductive sheet 11, passes through fin-shaped heat conduction
Piece 11 has larger heat-conducting area, improves heat transfer efficiency.
Wherein, one end of heat-conducting block 3 is fixed with strip fin 4, will be generated in tire motion process by heat-conducting block 3
