Abstract

The invention discloses a self-reinforcing drum brake with a ventilating and cooling device. The self-reinforcing drum brake comprises a brake drum, a first brake shoe and a second brake shoe. An air cylinder is arranged on the first brake shoe. One side of the first brake shoe can abut against a piston of the air cylinder. An ejector rod is arranged on the other side of the first brake shoe. One end of the ejector rod abuts against the first brake shoe, and the other side of the ejector rod abuts against the second brake shoe. The other side, abutting against the ejector rod, of the second brake shoe is hinged to an external rack and provided with a tension spring. A plurality of cooling holes are formed in the first brake shoe and the second brake shoe. According to the scheme, the self-reinforcing drum brake has the beneficial effects that the cooling holes are additionally formed in the brake shoes, then heat generated under the action of friction force of the brake shoes can have a larger cooling area, the temperature of the brake shoes is kept within a proper range, and the stability and reliability of the work performance of the brake are improved.

Description

technical field [0001] The invention relates to a drum brake, in particular to a self-energizing drum brake with a ventilation cooling device. Background technique [0002] The brake is mainly used to limit the speed of the running machinery or mechanism or stop it. The brake is an important part to protect the safe and normal operation of the machinery and control the speed of the machinery. [0003] Drum brake is a commonly used brake. When braking, the drum brake relies on the friction between the brake shoe and the brake drum to achieve the braking effect of the brake drum. Therefore, during the braking process, the brake The shoe will generate a lot of heat under the action of friction. If the heat is not dissipated in time, it will cause the wear of the brake shoe and affect the working performance of the brake. Contents of the invention [0004] The present invention intends to provide a self-energizing drum brake with a ventilation cooling device to solve the prob...
