Abstract
The invention discloses a circuit for an automatic water-spraying device of a brake. The circuit comprises a storage battery, a relay, a control switch, a braking switch, a temperature-controlled switch and a water pump motor, wherein the positive electrode of the storage battery is connected with a working circuit of the relay, and connected with a control circuit of the relay after being sequentially connected in series with the control switch, the braking switch and the temperature-controlled switch; and the water pump motor is connected with the working circuit of the relay. By adopting the circuit provided by the invention, the temperature of a brake hub of an automobile can be lowered so as to avoid the heat fade of the brake to avoid impact on traveling security, which is caused by the remarkably descended braking efficiency of the automobile. The circuit has the characteristics of simple structure and low failure rate.
Description
Technical field
The present invention relates to a kind of car brake automatic spraying device circuit.
Background technology
When automobile when mountain road travels, often can run into the road that descending is very long and bend is more, at this moment chaufeur often needs to brake with regulation speed for a long time for safety.Because continue braking, drg is drum brake mechanism particularly, its temperature can rise very fast, when temperature reaches more than 300 ℃, friction moment will significantly descend, and " heat fade " phenomenon of drg occurs, causes the remarkable decline of brake efficiency and has a strong impact on traffic safety.
Summary of the invention
For above-mentioned prior art, the technical problem to be solved in the present invention provides a kind of drg automatic spraying device circuit of simple in structure, failure rate is low.
For solving the problems of the technologies described above, a kind of drg automatic spraying device circuit provided by the invention comprises storage battery, relay, master cock, brake switch, coolant-temperature switch, pump motor; Wherein, the positive pole of described storage battery connects the pull up circuit input end of described relay; Simultaneously, the positive pole of described storage battery is connected in series the input end that connects the control circuit of described relay behind master cock, brake switch, the coolant-temperature switch successively; The pull up circuit mouth of described relay connects the power end of described pump motor.
As improvement of the present invention, described alarm lamp connects the control pull up circuit mouth of relay.
As a further improvement on the present invention, this circuit also comprises insurance, and described insurance is connected between the pull up circuit of the positive pole of described power supply and relay.
A kind of drg automatic spraying device circuit provided by the invention, this circuit have that structure is simple, the characteristics of failure rate is low.When battery relay was worked, alarm lamp was bright, plays suggesting effect.
Description of drawings
Fig. 1 is drg automatic spraying device schematic circuit diagram.
The specific embodiment
Reach technological means and the effect that predetermined purpose is taked for further setting forth the present invention, below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
As shown in Figure 1, a kind of drg automatic spraying device circuit provided by the invention comprises storage battery 1, insurance 2, relay 3, master cock 4, brake switch 5, coolant-temperature switch 6, pump motor 7.Wherein, the pull up circuit input end of the positive pole of storage battery 1 series connection insurance 2 rear connection relays 3.The positive pole of storage battery 1 is connected in series the control circuit of master cock 4, brake switch 5, coolant-temperature switch 6 rear connection relays 3 successively.The pull up circuit mouth of relay 3 connects the power end of described pump motor 7.This circuit also comprises alarm lamp 8, and alarm lamp 8 connects the control pull up circuit of relay 3.
A kind of drg automatic spraying device circuit real work situation provided by the invention is as follows:
When automobile entered mountain road and travels, chaufeur is topped up with water in bucket, and handled master cock 4 and make it closed; As making the brake hub temperature be higher than 300 ℃, coolant-temperature switch 6 closures because of frequent braking, at this moment, chaufeur is stepped on the control circuit that 28 of brake pedals can cutin relay 3 again, the pull up circuit work of relay 3, the switch adhesive of pull up circuit, pump motor 7 work, water in the bucket in the boot is extracted out and poured on the brake hub, brake hub is lowered the temperature, with the assurance traffic safety, and this moment, alarm lamp 8 was lighted, and reminding driver is taken care, note drive manner, rest temperature-reducing in case of necessity can stop.
The above has done detailed description to embodiments of the present invention by reference to the accompanying drawings, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also not break away under the prerequisite of aim of the present invention and make various variations.
