Abstract

The invention belongs to the technical field of automobiles, and particularly relates to a drum brake. The drum brake is provided with a driving fan type heat dissipation device. During automobile braking, the heat dissipation device starts to achieve the heat dissipation function, the automobile brake heat dissipation performance is improved, heat fading of the brake is prevented, and the temperature of the whole brake is controlled under the work conditions that the brake needs continuous braking during long downhill. According to the heat dissipation device of the drum brake, when an automobile normally runs and braking is not conducted, the heat dissipation device does not work, the self service life can be prolonged, and self reliability of the heat dissipation device is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a drum brake. The invention also relates to an automobile braking system and an automobile. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] The existing drum brake is limited by its own structure, and the brake shoe basically works in a closed space. When the vehicle brakes, it will produce a relatively rapid temperature rise, and the heat is not easy to dissipate to the external space, so Drum brakes tend to reach very high temperatures when the car is braked for long periods of time. At present, some drum brakes use passive heat dissipation to reduce their own temperature. The cooling process is relatively slow and long, and it is easy to cause the brake force to decline or even brake failure due to excessive temperature. Contents of the invention ...
