Background

Drum brakes have been used in automobiles for a century ago, but are still being deployed today on many models (mostly for rear wheels) due to their reliability and strong braking force. It is fixed to the tyre and rotates at the same speed. During braking, the brake shoe is pushed by oil pressure to contact the inner edge of the brake drum, and the friction force generated by the contact is used to restrain the rotation of the tire so as to achieve the purpose of braking. The drum brake consists of a brake bottom plate, a brake cylinder, a brake shoe and other relevant connecting rods, a spring, a pin nail and a brake drum. Currently, the rear wheel is generally mounted. The drum brake has lower cost and higher absolute braking force, and the inner surface of the brake drum of the drum brake is the position of the brake device for generating the braking torque. The diameter of the brake drum of a drum brake assembly can be much smaller than the diameter of the brake disc of a disc brake assembly to achieve the same braking torque.
