Abstract

The invention discloses a heavy-duty commercial vehicle brake micro liquid cooling device and a control method thereof. The device comprises a high-pressure gas pipeline, a liquid tank and a control system. One end of the high-pressure gas pipeline is connected with a high-pressure gas inlet, and a nozzle is arranged at the other end of the high-pressure gas pipeline and is close to a brake. A venturi is arranged on the high-pressure gas pipeline and communicates with a fine tube extending into the liquid tank. The control system controls high-pressure gas to enter the venturi along the high-pressure gas pipeline, differential pressure is formed between the venturi and the liquid tank, liquid in the liquid tank enters the venturi along the fine tube under the action of the differential pressure, and the liquid is sprayed to the brake along with the high-pressure gas from the nozzle after being atomized under the contraction action of the nozzle. Through the device and the control method thereof, the temperature of the vehicle brake is not increased, thus the hot water subsidence phenomenon does not occur when the heavy-duty commercial vehicle brake brakes for a long time.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a trace liquid cooling device for brakes of heavy-duty commercial vehicles and a control method thereof. Background technique [0002] During the long-term braking process of heavy-duty commercial vehicles, due to the friction between the brake drum and the brake of the vehicle brake, the brake will produce thermal degradation, which will lead to the failure of the vehicle brake and serious traffic accidents. If the car is going down a long slope, it must be braked for a long time, so the thermal recession of the brakes is inevitable. However, in winter, watering the brakes will cause the road to freeze, so the relevant laws prohibit the car from going down. Sprinkle water to cool down during the slope process. Therefore, the cooling of automobile brakes is an important part of the current commercial vehicle brake design. Contents of the invention [000...
