Problems solved by technology

However, due to the inability to accurately control the amount of water and the large amount of water sprayed by the direct spray type, the cooling water sprayed on the brake drum cannot be completely evaporated, the cooling efficiency is low, and part of the cooling water flows to the road surface, causing the road surface to be slippery, affecting traffic safety, and , in the actual braking process, the inner side of the brake drum will generate a lot of heat to make its temperature very high, while the temperature of the cooling water is close to the air tem

Abstract

The invention discloses a brake cooling method and a brake cooling device. Collected temperature values of a brake are obtained in real time through a controller (5); when the temperature value of the brake is greater than a preset temperature value, the opening degree of a first electromagnetic valve (4) and the opening degree of a second electromagnetic valve (8) are controlled, so that water in a water tank (1) is atomized and sprayed to the inner side of a brake drum of the brake by an atomizing spray head (7) through pressured air in an air storage tube (2); the goals of regulating and controlling the quantity of cooling water according to the temperature condition of the brake, reasonably and effectively using cooling water, further improving the cooling efficiency, avoiding wet and slippery conditions of the pavement caused by the cooling water and saving water resources are achieved; the goals of atomizing the cooling water and uniformly spraying the cooling water to the inner side of the brake drum are achieved by using the atomizing spray head; the problem of local cracking due to greater temperature differences at the inner and outer sides of the brake drum caused by direct showering type cooling is effectively avoided; and the running safety of vehicles is further improved.

Description

technical field [0001] The invention relates to the technical field of automobile brakes, in particular to a brake cooling method and device. Background technique [0002] Today, the brake cooling device occupies a major position among the factors that ensure that the automobile braking system has better braking performance during the braking process. [0003] At present, for the cooling problem of the traditional drum brake during the braking process, the way of cooling water directly pouring the brake drum is usually used, that is, the cooling water in the water tank is directly poured to the brake drum of the drum brake through the water pipe. on the outside of the drum. However, due to the inability to accurately control the amount of water and the large amount of water sprayed by the direct spray type, the cooling water sprayed on the brake drum cannot be completely evaporated, the cooling efficiency is low, and part of the cooling water flows to the road surface, caus...
