Abstract
The invention relates to a drum type brake which can be used for forcing the interior of a brake drum to ventilate. According to the drum type brake, vent holes are formed in a bottom plate of the brake and connected with an air outlet of an electric blower; and through the control of a control circuit, air is blown into the drum type brake by the blower in a period of set time during and after braking a vehicle so as to force ventilate and radiate the drum type brake.
Description
Affiliated technical field
The present invention relates to a kind of drum brake, it is that air cooled drum brake is forced in a kind of employing.
Background technique
At present, known automobile drum brake, the heat that produces during its braking, mainly be to dispel the heat by the outer surface ventilation of brake drum, and internal surface is in the environment of relative closure, substantially there is not Air Flow, so some vehicle the Braking efficiency attenuation phenomenon occurs because of brake overheating when lower long slope; The overheated main method of drum brake is to brake drum outer surface trickle in the solution automobile running at present, not enough is: liquid distribution is bulky, to more increase car weight and supply work, water can flow to the road surface, when temperature above freezing, can be played by wheel and form the front windscreen that water smoke pollutes rear car, when temperature below freezing, can build-up ice on the road surface, reduce the frictional force on road surface, stay great potential safety hazard can for other vehicle.
Summary of the invention
In order to increase the radiating efficiency of existing drum brake, the invention provides a kind of drum brake with the forced air cooling heat radiation, it can be blown in the brake drum by the air that car is outer when braking, but also ventilation and heat of the internal surface that makes brake drum.
The technical solution used in the present invention is: offer vent hole at the braking bottom board that brake shoe is installed, connect electric blower, during braking, force to be blown into fresh air to take away the heat in the brake drum in brake drum.The control circuit of its motor is: power supply is by Control, and the work of relay is controlled by delay switch, and the work of delay switch is triggered by braking light switch.When braking occurs, braking light switch conducting energising, electric current moment is full of triggers high power valve by resistance again behind the electric capacity and makes it the conducting energising, make electric current flow into relay magnetic coil, inhale lower contact, the power circuit of motor is connected, blower work is blown into air in the brake drum.When cancellation braking, braking light switch disconnects, and electric capacity discharges to high power valve by resistance, and control relay disconnects after touching and continuing to close a period of time, makes blower still be blown into fresh air in a period of time after stopping to brake; Air in the brake drum then flows out outside the brake drum by the gap between braking bottom board and the brake drum; Capacitor discharge is complete, the high power valve cut-off, and open relay magnetic coil blackout, contact, electric motor circuit breaking, blower quits work.During without forced ventilation, cutting off the electricity supply gets final product.
Advantage of the present invention is: air directly flows through rubbing surface, and radiating effect is direct, need not to change structure and the outward appearance of vehicle, and lightweight, volume is little, need not logistic support.
Description of drawings
That the present invention is further described below in conjunction with accompanying drawing and embodiment:
Fig. 1 is structural drawing of the present invention.
1. brake backing plates among the figure, 2. brake drum internal surface, 3. electric blower 4. Air Flow routes, 5. motor, 6. normally opened relay, 7. delay switch, 8. braking light switch, 9. vent hole, 10 air outlets, 11. control circuits.
Embodiment
Among Fig. 1, opening vent hole (9) at brake backing plate (1) is connected with the air outlet (10) of electric blower (3), the outer air of car directly blows to brake drum internal surface (2) when being blown in the brake drum, and the direction indication that follows Air Flow route (4) flows; The supply terminals of motor (5) connects a contact that connects normally opened relay (6) of control circuit (11), an other contact of normally opened relay (6) then connects positive source, the magnetic coil one end bonding of normally opened relay (6), the other end connects a terminal of delay switch (7), the b wiring termination power of delay switch (7), c terminal are connected with a contact of braking light switch (8), and another contact of braking light switch connects positive source.
Claims (1)
1. drum brake, it is comprised of common drum brake and electric blower, it is characterized in that: the brake backing plate at drum brake is offered vent hole, and is connected with the air outlet of electric blower.
