Technical Field
The utility model belongs to the technical field of the automobile cooling, a wet brake self-loopa cooling system is related to.
Background
If the automobile brake works for a long time, or continuous emergency braking will be overheated because of friction, lead to coefficient of friction to reduce, will influence braking effect like this, this just can be explained as heat decline, in the current technique that is used for solving automobile brake heat decline, though the heat decline problem has been solved successfully, but the radiating system's of general stopper coolant oil need dispel the heat through heat transfer to heat dissipation water tank with heat, make the temperature of stopper and coolant oil too high easily, produce the potential safety hazard, reduce vehicle parts life, the pipe arrangement is complicated and the price/performance ratio is not high.

Detailed Description
For the convenience of understanding, the technical solution of the present invention is further described in detail below by way of embodiments with reference to the accompanying drawings:
as shown in fig. 1, the self-circulation heat dissipation system of the wet brake comprises a cooling oil tank 1, a filter 2, a gear pump 3, a heat dissipation pipeline 4 and a brake 7.
The cooling oil tank 1 is connected with the filter 2 through an oil pipe. The filter 2 is connected to the gear pump 3 via a line.
An oil outlet of the gear pump 3 is provided with an oil inlet pipe 9, and the other end of the oil inlet pipe 9 is connected with an oil way inlet of the brake 7.
The power source of the gear pump 3 is an engine, and the gear pump 3 is driven by the engine to work.
An oil outlet pipe 10 is arranged on an oil path outlet of the brake 7, the other end of the oil outlet pipe 10 is connected with the heat dissipation pipeline 4, and the other end of the heat dissipation pipeline 4 is connected to the cooling oil tank 1 through an oil pipe.
The oil outlet pipe 10 is provided with a temperature sensor 8, and the temperature sensor 8 can sense the temperature of the oil in the oil outlet pipe 10 at any time.
A fan 6 is arranged on one side of the heat dissipation pipeline 4, and the fan 6 is connected with a temperature sensor 8 through a lead.
An oil overflow pipe 11 is arranged on the oil inlet pipe 9, and an electronic throttle valve 5 is arranged on the oil overflow pipe 11. The other end of the oil spill pipe 11 is communicated with the cooling oil tank 1 through an oil pipe.
The working principle is as follows: the engine drives the gear pump 3 to work, the gear pump 3 pumps cooling oil out of the cooling oil tank 1, the cooling oil is filtered by the filter 2 and enters the brake 7 through the oil inlet pipe 9, and the heat dissipation of the brake is realized; the warmed cooling oil flows into the heat dissipation pipeline 4 through the oil outlet pipe 10, and the heat dissipation pipeline 4 dissipates the heat of the oil into the air. Temperature sensor 8 responds to the temperature of oil in oil pipe 10 exit at any time, and when temperature sensor 8 detected the high temperature of cooling oil, temperature sensor 8 automatic switch-on started fan 6, and fan 6 opened, forced air and heat dissipation pipeline 4 heat transfer realize strengthening the cooling. The opening and closing of the electronic throttle valve 5 can be controlled by the data of the temperature sensor 8, and the flow rate of the cooling oil entering the brake 7 is changed by the electronic throttle valve 5. The oil in the oil outlet pipe 10 and the oil spill pipe 11 finally flows back to the cooling oil tank 1 for reuse, and self-circulation is realized.
The above embodiments are merely illustrative or explanatory of the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention, and it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
