Abstract

The invention discloses a bicycle brake drum with abrasion resistant rubbers in the technical field of bicycle brake drums. The bicycle brake drum comprises a brake drum body; a brake bottom plate isarranged on the rear side in the brake drum body; two groups of friction linings are arranged on the inner walls on the left side and the right side of the brake drum body; brake shoes are arranged onthe other sides of the two groups of friction linings; a plurality of groups of brake pad placing holes are formed in each brake shoe; hole sleeves are arranged in the brake pad placing holes; the abrasion resistant rubbers are arranged in the hole sleeves; brake wheel cylinders are arranged at the top ends of the two groups of brake shoes; return springs are arranged at the tops of the two groups of brake shoes, and are positioned below the brake wheel cylinders; ejector rods are arranged at the bottoms of the brake shoes; the two ends of the ejector rods are connected with the brake shoes by means of supporting pins; a wheel shaft hole is formed in the middle of the brake bottom plate; and a bearing hole is formed in the outer edge of the front end of the wheel shaft hole. The bicycle brake drum is simple in structure, and the hole sleeves are used to enable the abrasion resistant rubbers to be conveniently mounted or dismounted, thereby being worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of bicycle brake drums, in particular to a bicycle brake drum with wear-resistant rubber. Background technique [0002] Drum brake is a good braking device for motor vehicles. When braking, the brake wheel cylinder is used to push the brake shoe to contact the inner edge of the brake drum, and the friction generated by the contact can restrain the rotation of the tire to achieve the purpose of braking. The drum brake is connected by the brake bottom plate, brake wheel cylinder, brake shoe, etc. Composed of rods, springs, pins, and brake drums. [0003] Traditional electric drum brakes generally use the brake wheel cylinder to separate the brake shoe for braking, and then reset it by a spring. This kind of brake structure is easy to slip, the friction deceleration effect is not ideal, and accidents are prone to occur. Contents of the invention [0004] The object of the present invention is to provide a b...
