Abstract

The invention discloses a drum brake cooled through heat pipes. The drum brake comprises a front brake shoe, a rear brake shoe, a friction plate, a brake shoe return spring, a brake cylinder, fan blades, the heat pipes and supporting pins. The multiple heat pipes are arranged on the front brake shoe, the rear brake shoe and the friction plate in a spaced mode. A brake drum body is mounted on the periphery of the friction plate and mounted on a wheel through brake drum mounting holes. The fan blades are mounted on the brake drum body which is provided with arc vent grooves. The heat pipe array is embedded between the brake shoes of the drum brake and the friction plate, the fan blades are arranged in the brake drum, and the role of a fan is played in the vehicle running process. Through the structural features, a large amount of heat generated in mutual friction of the friction plate and the brake drum in the vehicle braking process can be quickly conducted into a brake drum chamber through the heat pipes, the heat is taken into the external environment through air flowing into the brake drum chamber, and therefore the temperature of the brake drum and the temperature of the friction plate are reduced, and the braking performance of the brake is more stable.

Description

technical field [0001] The invention relates to a vehicle brake (that is, a brake device), in particular to a rapid heat conduction through a heat pipe, so as to achieve rapid heat dissipation, avoid excessive temperature rise of drum brake components, thermal recession, and brake failure, and belong to automobiles. Spare parts technical field. Background technique [0002] To slow down or even stop a moving car, keep the speed of a downhill car stable, and keep a stopped car still, these functions are collectively called car braking. The brake is a component used in automobile braking to generate a force that hinders the movement or movement tendency of the vehicle. At present, the brakes used in all kinds of automobiles are almost all friction brakes, and the friction brakes used in automobiles can be divided into two categories: drum type and disc type. Among them, the drum brake has high braking efficiency, simple structure and flexible space arrangement, and has been ...
