The drum brake is characterized in that the brake block is arranged in the sealed brake drum, so that a large amount of heat is generated in the process of long-time brake and is gathered on the brake block and cannot be dissipated timely, the temperature of the brake block rises quickly, heat fading occurs, the brake efficiency is reduced, the brake distance is increased, and due to the sealing arrangement of the brake, abrasion dust generated in the brake block in the brake process is easy to deposit on the brake block, the brake efficiency of the drum brake in the brake process is further influenced, and the drum brake has great potential safety hazard.

Although the disc brake solves the problem of the upper drum brake, the disc brake has a smaller contact area between the brake pad and the brake disc, so that the generated braking force is far inferior to that of the drum brake, and therefore, a braking mechanism is needed to enhance the heat dissipation effect while ensuring good braking force, so as to effectively avoid the heat fading phenomenon generated in the long-time braking process.
