Description
Technical field
The utility model is related to brake field, and in particular to a kind of drum brakes of high efficiency and heat radiation.
Background technology
Drum brakes is usually used on the rear wheel of private car, realizes that deceleration stops by the friction between brake pad and brake drum
Car, in friction process, brake block can largely radiate, if can not radiate in time, braking quality can be caused to decline, bring safety
Hidden danger.
Utility model content
Utility model purpose：The utility model is intended to overcome the defect of prior art, and there is provided a kind of drum-type of high efficiency and heat radiation
Brake.
Technical scheme：A kind of drum brakes, including fixed plate, first brake piece, the second brake block, the first steady pin,
Two steady pins, back-moving spring, brake pump, the first brake piece include first brake hoof and the first brake pad, and described first stops
The end of car hoof is fixed with the first abutment sleeve that can be rotated around first steady pin, and second brake block includes the
Two brake shoes and the second brake pad, the second brake shoe end are fixed with can be rotated around second steady pin second
Being fixed with abutment sleeve, the fixed plate in the rigid tubing with air inlet and air outlet, the rigid tubing has fan, institute
Stating has the second of both ends open to dissipate in first heat dissipation channel in first brake hoof with both ends open, second brake shoe
The passage of heat, described first heat dissipation channel one end connects the air outlet of the rigid tubing by the first pipeline, and second radiating is logical
The one end in road connects the air outlet of rigid tubing by the second pipeline.
Further, the air outlet of the rigid tubing is connected with first jet by the 3rd pipeline, and the first jet is used
In the outer surface for purging the first brake pad；The air outlet of the rigid tubing is connected with second nozzle by the 4th pipeline, described
Second nozzle is used for the outer surface for purging the second brake pad.
Further, first and second pipeline is flexible pipe, and third and fourth described pipeline is hard tube.
Further, there is first thermal insulation layer, second brake shoe between the first brake hoof and the first brake pad
And second have second thermal insulation layer between brake pad.
Further, the rigid tubing is bonded and fixed in the fixed plate.
Further, first and second nozzle is bonded and fixed in the fixed plate.
Beneficial effect：Drum brakes of the present utility model, can produce the outer of the brake pad of gas flow purging first by fan
Side and the outside of the second brake pad, so that cooling is realized, and the heat of brake shoe is taken away by the air-flow of heat dissipation channel.So as to cold
It is quick.
