Abstract

The invention relates to a thread type braking device used for a mechanical disk brake of a bicycle. The thread type braking device comprises a double-shaft connecting rod, a brake cable connecting part is arranged at the upper end of the double-shaft connecting rod, and a first shaft arm and a second shaft arm which are of the 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 end of the first shaft arm and the lower end of the second shaft arm respectively. A first braking assembly and a second braking assembly which are of the same structure are installed in the first shaft arm hole and the second shaft arm hole respectively. Double-side braking can be achieved when the thread-type braking device is installed in the mechanical disk brake, a disk is not prone to deformation, and a brake pad is not prone to abrasion. The thread type braking device is good in braking effect, low in cost and simple and practical in structure and has the oil pressure double-side braking effect and the labor saving effect, and meanwhile oil leakage will not occur.

Description

technical field [0001] The invention belongs to the field of bicycle disc brakes, in particular to a threaded brake 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.
