Description

TECHNICAL FIELD

[0001] The utility model relates to brake shoe heat dissipation structure technical field, concretely relates to a quick heat dissipation structure of brake shoe. BACKGROUND

[0002] In the automobile brake system, the brake shoe plays a vital role, and its performance is directly related to the braking effect and driving safety of the vehicle. With the continuous development of the automobile industry, the driving speed of the vehicle is continuously improved, and the braking frequency is also increased accordingly, so that a large amount of heat is generated in the working process of the brake shoe. The traditional brake shoe heat dissipation mainly relies on natural convection and radiation to dissipate heat to the surrounding environment, and the heat dissipation efficiency is low. Therefore, a heat dissipation structure is needed during the use of the brake shoe to quickly and effectively dissipate the large amount of heat generated in the working process of the brake shoe, so as to ensure that the brake shoe is always within a suitable working temperature range.

[0003] In the application number 202420339024.9, a drum brake shoe with heat dissipation structure is disclosed, "the heat dissipation component includes a plurality of heat dissipation fins arranged in a circle on one side of the heat dissipation fin and a heat conduction plate arranged on one side of the heat dissipation fin below the heat dissipation fin, the heat dissipation fin is fixedly connected with the heat dissipation fin, the heat conduction plate is fixedly connected with the heat dissipation fin, and the heat dissipation fin and the heat conduction plate are in contact with the brake shoe body", "in addition, in order to further dissipate heat from the brake shoe body, a plurality of heat dissipation holes are arranged in a circle on the heat dissipation fin, and contact openings are arranged on both sides of the heat dissipation holes, the contact openings are trumpet-shaped, the contact openings can increase the contact area with hot air, the hot air can be guided to the other side of the heat dissipation fin, and the heat dissipation efficiency can be further improved", although the above-mentioned heat dissipation structure utilizes the heat dissipation fin, the heat conduction plate, the heat dissipation hole and the trumpet-shaped contact opening to build a relatively complete heat dissipation system, which helps to dissipate heat from the brake shoe to a certain extent, and the special shape of the contact opening increases the contact and conduction efficiency of the hot air and the heat dissipation fin to a certain extent, but the heat dissipation structure mainly relies on the natural convection and conduction of air to dissipate heat. Under the working conditions of high-speed driving and frequent braking of the vehicle, it is difficult to quickly and effectively remove the high heat generated, so that the temperature of the brake shoe continues to rise, which leads to heat recession phenomenon, affects the timeliness and effectiveness of braking, and brings potential risks to driving safety.
