Abstract

The invention relates to a brake device used for a mechanical disc brake of a bicycle. The brake device comprises a double-shaft connecting rod, wherein a brake cable connecting part is arranged at the upper part of the double-shaft connecting rod; a first shaft arm and a second shaft arm both in same structure are connected to the two sides of the brake cable connecting part respectively; a first shaft arm hole and a second shaft arm hole are formed in the lower ends of the first shaft arm and the second shaft arm respectively; a first brake component and a second brake component in the same structure are mounted in the first shaft arm hole and the second shaft arm hole respectively. The brake device is mounted in the mechanical disc brake and can realize bilateral braking, a disc plate is enabled to be not deformed easily, a brake pad is abraded hardly, and a good braking effect is achieved. A bilateral braking effect with an oil pressure is achieved, and an oil leakage phenomenon is avoided. The cost is low, and the structure is simple and practical.

Description

technical field [0001] The invention belongs to the field of bicycle disc brakes, in particular to a braking device for mechanical disc brakes of bicycles. Background technique [0002] The bicycle disc brake is composed of a brake disc connected to the wheel and a brake device on the edge of the disc. When braking, the brake pads are pushed to clamp the brake disc to produce a braking effect. At present, it is distinguished by the way the brake is activated, or by the medium that the actuating brake pad holds the disc. One is the brake line and the other is oil. Mechanical disc brakes rely on the tension of the brake line to make the brake pads in the caliper rub and clamp the disc to produce a braking effect. Hydraulic disc brakes use oil as the medium, pull the brake handle to make the piston compress the oil, and the pressure goes straight from the oil pipe to the caliper, thereby pushing the piston in the caliper to drive the brake pads to clamp the disc. [0003] In...
