Gas braking subsidiary cooling system

Abstract

The invention discloses a gas braking subsidiary cooling system. The gas braking subsidiary cooling system is provided with a gas nozzle and an atomizing water nozzle, and the gas nozzle and the atomizing water nozzle are correspondingly connected with a gas nozzle relay valve and an atomizing water nozzle relay valve through pipelines; and a gas nozzle relay valve control opening and an atomizingwater nozzle relay valve control opening are connected with air braking pipelines through the pipelines. By adopting the above technical scheme, in the process of vehicle braking and under emergencycircumstances, compressed air and atomized water are sprayed to a brake to make the brake be subjected to rapid heat dissipation and cooling, the brake is prevented from overheating and spontaneous combustion, fire risks are avoided, and thus the vehicle safety and the road traffic safety are improved; a teat can be carried out after common braking elements in the market are connected, the quantity of elements composing the system is small, the structure is simple, and the cost can be saved greatly; and the performance is reliable, the gas braking subsidiary cooling system can share an air pressure source with a braking system, and the installation and use are convenient.

Description

technical field [0001] The invention belongs to the technical field of air brakes for automobiles and engineering machinery. More specifically, the present invention relates to an air brake auxiliary cooling system for quickly dissipating heat from the brake. Background technique [0002] Heavy-duty trucks, trailers and wheeled construction machinery due to their heavy weight, emergency braking or long-distance driving in climates with high ambient temperature, due to the intense friction of the brake friction plate, the heat generated is large, which may easily lead to thermal degradation of the brakes and a decrease in thermal stability , The braking distance is extended. In severe cases, it may even cause spontaneous combustion of tires and wheel hubs, affecting driving safety and road traffic safety. [0003] But up to now, there is no air brake auxiliary cooling system that can make the wheel hub dissipate heat quickly in the field of air brakes of automobiles, traile...
