Description

Technical Field

[0001] The present invention relates to the technical field of brake equipment, and in particular to a gear type brake assembly. Background Art

[0002] When the drum brake is applied, the brake shoe opens outward, and the friction pad fixed on the brake shoe rubs against the inner side of the brake drum, forcing the brake drum and the wheel to slow down until they stop.

[0003] For example, the Chinese patent with publication number CN218408247U and name "A drum brake assembly" includes a drum body, two rotating rods, a pull rod and a protection mechanism. The protection mechanism includes two brake pads, two cams, two limit assemblies and two friction pads. When braking, the pull rod is pulled to drive the two rotating rods to rotate, and the two rotating rods drive the two cams. The rotation of the two cams increases the distance between the two brake pads, and the two brake pads slide on the drum body. The two friction pads on the two brake pads rub against the drum body to increase the friction force of the brake pads. When the two cams are aligned with the sides of the two brake pads, the two limit assemblies pop into the two brake pads to fix the two brake pads, which can prevent the two cams from rotating beyond the preset value. The two brake pads cannot contact the drum body, resulting in the two brake pads being unable to brake the wheel, thereby solving the problem of low safety of existing drum brakes.

[0004] The shortcoming of the existing technology is that since the drum brake structure is a closed structure, it cannot be observed from the outside during normal use. As a result, the brake effect is reduced due to the wear of the brake pads, and the brake failure caused by the wear of the brake pads cannot be effectively intervened, resulting in the failure of the brake pads due to wear. Summary of the invention
