Abstract

The present invention relates to a kind of automobile drum type brake heat dissipation system, belong to automobile brake technical field.Include axletree, wheel hub, brake drum, brake-shoe, wheel hub is connected with brake drum, and brake drum inner chamber is configured with brake-shoe, it is characterised in that install wind wheel or flabellum at brake drum inner chamber, and offer air admission hole in the outside of brake drum, the opposite side at brake drum arranges exhaust outlet.Present invention achieves the brake drum inner chamber forced ventilation heat radiation of relative closure so that extraneous cold air can continue into brake drum inner chamber, reached the effect of cooling, thus ensure brake system of car stable performance and properly functioning;The forced ventilation of braking inner chamber can make braking inner chamber keep cleaning and good ventilation effect so that the radiating effect of automobile drum type brake is further improved;Present configuration is simple, reasonable in design, and serviceability is reliable, and safe and reliable to operation, service life is long, and conveniently can reequip on existing automobile, beneficially energy-conserving and environment-protective.

Description

A kind of automobile drum type brake heat dissipation system
Technical field
The present invention relates to a kind of automobile drum type brake heat dissipation system, belong to automobile brake technical field.
Background technology
Automobile drum type brake is owing to having simple in construction, and the plurality of advantages such as braking torque is big, low cost of manufacture, easy to maintenance are the most still widely used on truck.Though existing automobile drum type brake has become perfect through repeatedly improving its braking ability, but brake or brake hard in the case of load is heavier, heat radiation after its friction catch still suffers from certain problem, Yi Yin braking produces high temperature and causes the accident of brake failure often to have generation, becomes major safety risks during vehicle travels.In order to solve the problem of above-mentioned existence, the radiating and cooling method of current automobile drum type brake is to install water-storing tank and liquid distribution on vehicle, reaches to force the purpose of cooling by drum brake carries out trickle.But, set up water tank and on the one hand increased the weight of the additionally heavy burden of automobile, decrease the carrying capacity that vehicle is limited, make troubles and bother the most also to road safety, the maintenance of vehicle, and also exist because liquid distribution inefficacy or misoperation bring potential safety hazard.When meeting cold weather, liquid distribution pipeline often cannot normally can use because of icing, or because trickle cooling causes road surface localized ice build induction traffic accident.Additionally, easily make brake drum rupture by trickle abrupt temperature drop under the condition of high temperature, even cause brake fade, travel to vehicle and lives and properties have serious consequences.
Summary of the invention
The technical problem to be solved be the deficiency existed for above-mentioned prior art and provide a kind of simple in construction, radiating effect substantially, the automobile drum type brake heat dissipation system of stable performance.
The present invention solves technical problem set forth above and the technical scheme used is: include axletree, wheel hub, brake drum, brake-shoe, wheel hub is connected with brake drum, brake drum inner chamber is configured with brake-shoe, it is characterized in that installing wind wheel or flabellum at brake drum inner chamber, and offer air admission hole in the outside of brake drum, the opposite side at brake drum arranges exhaust outlet.
It is connected with brake drum or wheel hub by bolt by such scheme, described wind wheel or flabellum.
It is connected with brake drum by the attachment bolt of brake drum and wheel hub by such scheme, described wind wheel or flabellum.
By such scheme, described air admission hole is positioned at the bottom outside brake drum or outer peripheral face, or the boundary transition position of bottom and outer peripheral face.
By such scheme, described air admission hole is circular and or kidney ellipsoid.
By such scheme, described exhaust outlet is opened on outside or the dust-blocking cover of brake-shoe.
By such scheme, described exhaust outlet is circular, oval or fan-shaped.
By 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.
The beneficial effects of the present invention is: 1, by installing wind wheel or flabellum at brake drum inner chamber and arranging inlet and outlet aperture, achieve the brake drum inner chamber forced ventilation heat radiation of relative closure, cold (low temperature) air making the external world can continue into brake drum inner chamber, the high temperature produced because of braking is got rid of from exhaust outlet endlessly, reach the effect of cooling, in addition, the rivet of band through hole is used between friction plate and brake shoe iron, the effect of braking heat radiation can be further enhanced, thus ensure brake system of car stable performance and properly functioning;2, braking inner chamber forced ventilation can by because of braking produce dust and other accumulate dust and discharge braking inner chamber in time, braking inner chamber is made to keep cleaning and good ventilation effect, guarantee that braking ability is stable, and the radiating effect of automobile drum type brake is further improved;3, present configuration is simple, reasonable in design, and serviceability is reliable, and safe and reliable to operation, service life is long, and conveniently can reequip on existing automobile;Owing to without installing water-storing tank and spray equipment, not only the braking ability of vehicle is more safe and reliable, and decreases the load of automobile, improve carrying capacity, reduce the cost of transportation of truck, saved water resource, be conducive to energy-conserving and environment-protective, also can reduce the hidden danger of road traffic accident.

Fig. 2 is the A-A sectional view in Fig. 1.
Fig. 3 is the radial view of brake shoe portion in one embodiment of the invention.
Detailed description of the invention
Embodiments of the invention are further illustrated below in conjunction with accompanying drawing.
Include axletree 11, axletree installs wheel hub 8 by bearing 9, the inner side of wheel hub is connected with brake drum 3 by ring flange attachment bolt, brake drum inner chamber is configured with brake-shoe, described brake-shoe includes brake shoe iron 10 and friction plate 5, friction plate is riveted by rivet 4 phase with through hole with brake shoe iron so that the heat produced between brake-shoe and brake drum is distributed timely, and radiating effect is strengthened further;Install wind wheel or flabellum 6, described wind wheel or flabellum in the nearly bottom of brake drum inner chamber to be connected with brake drum by the attachment bolt of brake drum and wheel hub, with wheel hub brake drum run-in synchronism;Air admission hole 7 is offered in the outside of brake drum, described air admission hole is positioned at the boundary transition position of the bottom outside brake drum and outer peripheral face, it is evenly distributed, air admission hole is circular and/or kidney ellipsoid, dust-blocking cover 1 it is provided with outside brake-shoe, exhaust outlet 2 is offered on dust-blocking cover, described exhaust outlet is circular and/or fan-shaped, it is evenly distributed, make the brake drum inner chamber can continual outside discharges heat and dust, keep unimpeded, it is possible to by the circumference or the axial gap that strengthen between dust-blocking cover and brake drum or directly remove dust-blocking cover and form vent ports.
