The invention relates to an automobile drum type brake heat dissipation system, and belongs to the technical field of automobile brakes. The automobile drum type brake heat dissipation system comprises an axle, a hub, a brake drum and a brake shoe, wherein the hub is connected with the brake drum, the brake shoe is configured in an inner cavity of the brake drum, and the automobile drum type brake heat dissipation system is characterized in that a wind wheel or a fan blade is arranged in the inner cavity of the brake drum, an air inlet is formed in the outer side of the brake drum, and an air outlet is formed in the other side of the brake drum. The automobile drum type brake heat dissipation system achieves forced ventilation heat dissipation in the inner cavity of the relatively-sealed brake drum, the exterior cold air can continuously enter the inner cavity of the brake drum, the effects of heat dissipation and cooling are achieved, and therefore performance stability and normal operation of the automobile brake system are ensured. The forced ventilation of the inner cavity of the brake drum enables the inner cavity of the brake drum to keep clean and the good ventilation effect, and the heat dissipation effect of the automobile drum type brake can be further improved. The automobile drum type brake heat dissipation system is simple in structure, reasonable in design, reliable in use performance, safe and reliable in operation, long in service life, capable of conveniently conducting refit on an existing automobile, and beneficial to saving energy and protecting environment.
Description
Technical field
The present invention relates to a kind of automobile drum braking radiation system, belong to the automobile brake technical field.
Background technique
Automobile drum braking is owing to having simple in structurely, and braking torque is large, low cost of manufacture, and the plurality of advantages such as easy to maintenance still is widely used on the truck so far.Though existing automobile drum braking has become perfect through repeatedly improving its braking ability, but in the situation that the heavier brake of load or emergency braking, still there is certain problem in heat radiation after its friction catch, the Yi Yin braking produces high temperature and causes the accident of brake failure that generation is often arranged, and becomes major safety risks in the Vehicle Driving Cycle.In order to solve the problem of above-mentioned existence, the radiating and cooling method of at present automobile drum braking is at vehicle water-storing tank and liquid distribution to be installed, and reaches the purpose of forcing cooling by drum brake being carried out trickle.Yet, set up the extra heavy burden that water tank has increased the weight of automobile on the one hand, reduced the limited carrying capacity of vehicle, the while also makes troubles to the maintenance of road safety, vehicle and bothers, and existence was lost efficacy because of liquid distribution or misoperation is brought potential safety hazard.The liquid distribution pipeline can often can't normally use because freezing when meeting cold weather, or brings out traffic accident because the trickle cooling causes local the freezing in road surface.In addition, by the trickle abrupt temperature drop brake drum is broken under the condition of high temperature, even cause braking failure, have serious consequences for Vehicle Driving Cycle and lives and properties.
Summary of the invention
Technical problem to be solved by this invention be the deficiency that exists for above-mentioned prior art and provide a kind of simple in structure, radiating effect obviously, the automobile drum braking radiation system of stable performance.
The present invention for the technological scheme that the technical problem that solves above-mentioned proposition adopts is: include axletree, wheel hub, brake drum, brake shoe, wheel hub and brake drum link, the brake drum inner chamber disposes brake shoe, it is characterized in that installing wind wheel or flabellum at the brake drum inner chamber, and offer inlet hole in the outside of brake drum, at the opposite side of brake drum relief opening is set.
Press such scheme, described wind wheel or flabellum link by bolt and brake drum or wheel hub.
Press such scheme, described wind wheel or flabellum link by attachment bolt and the brake drum of brake drum and wheel hub.
Press such scheme, described inlet hole is positioned at bottom or the outer circumferential face in the brake drum outside, or the boundary transition position of bottom and outer circumferential face.
Press such scheme, described inlet hole is circular and or oval shape.
Press such scheme, described relief opening is opened on the outside or dust-blocking cover of brake shoe.
Press such scheme, described relief opening is circular, oval or fan-shaped.
Press such scheme, described brake shoe includes brake shoe iron and friction plate, and friction plate is riveted by the rivet with through hole mutually with brake shoe iron.
Beneficial effect of the present invention is: 1, by installing wind wheel or flabellum at the brake drum inner chamber and the inlet and outlet aperture being set, realized the brake drum inner chamber forced ventilation heat radiation of relative closure, so that extraneous cold (low temperature) air can continue to enter the brake drum inner chamber, to get rid of from relief opening endlessly because of the high temperature that braking produces, reached the effect of cooling, in addition, between friction plate and brake shoe iron, adopt the rivet with through hole, the effect of braking heat radiation be can further strengthen, thereby brake system of car stable performance and normal operation guaranteed; 2, the forced ventilation of braking inner chamber can accumulate dust with the dust that produces because of braking and other and in time discharge the braking inner chamber, the braking inner chamber is kept clean and good ventilation effect, guarantee that braking ability is stable, and so that the radiating effect of automobile drum braking be further improved; 3, the present invention is simple in structure, and is reasonable in design, and usability is reliable, safe and reliable to operation, long service life, and can on existing automobile, conveniently reequip; Owing to need not to install water-storing tank and spray equipment, not only the braking ability of vehicle is more safe and reliable, and has reduced the load of automobile, improve carrying capacity, reduced the cost of transportation of truck, saved water resources, be conducive to energy-conserving and environment-protective, also can reduce the hidden danger of road traffic accident.
