Brake cable adjusting mechanism based on bicycle disc brake

Abstract

The invention relates to the technical field of bicycle disc brake mechanisms, and discloses a brake cable adjusting mechanism based on a bicycle disc brake. The brake cable adjusting mechanism comprises a disc brake body, wherein a rotating arm is movably connected to the middle part of the front surface of the disc brake body in a sleeved mode; a pressure sleeve is fixedly arranged at one side of the bottom end of the rotating arm; an auxiliary support rod is arranged at the bottom of an inner cavity of the pressure sleeve; and a pressure spring is movably connected to the outer surface of the auxiliary supporting rod in a sleeved mode. According to the brake cable adjusting mechanism based on the bicycle disc brake, through the arrangement of the pressure sleeve, the pressure spring anda main support rod, the main support rod is driven to extend outwards through the elastic force of the pressure spring in order to increase the rotating return radius of a movable pressing block in the braking action, so that a brake cable can be in a tensioned state all the time, the phenomena that the brake pressure is reduced and the brake distance is increased due to looseness caused by abrasion in the long-term use process are avoided, and the brake performance of the bicycle disc brake is effectively improved.

Description

technical field [0001] The invention relates to the technical field of bicycle disc brake mechanisms, in particular to a brake line adjustment mechanism based on bicycle disc brakes. Background technique [0002] In order to improve the braking efficiency of bicycles and their safety during riding, disc brakes are generally used on bicycles, and brake lines are used to control the friction brake pads of calipers to provide friction braking force for bicycles. . [0003] However, during the long-term use of the existing brake lines, various wear and tear will lead to slack, which leads to the need to increase the relative displacement of the brake lines to compensate for the slack of the brake lines when braking. amount, thereby increasing the reaction time of the braking action, and because the displacement of the brake handle is constant, and the displacement of the calipers is controlled by different displacements to provide corresponding braking pressure for the brake pa...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a brake line adjustment mechanism based on bicycle disc brakes, which can automatically adjust the tightness of the brake line, will not loosen during long-term use, and always maintains good braking performance, stability and The advantage of high safety solves the problem that the existing brake line will loosen due to various wear and tear during long-term use, which leads to the need to increase the relative displacement of the brake line when people perform braking actions amount to compensate the slack of the brake line, thereby increasing the reaction time of the brake action, and because the displacement of the brake handle is certain, and the displacement of the caliper is controlled by different displacements to provide corresponding braking pressure for the brake pads Therefore, when the slack of the brake line is compensated, the braking pressure of the caliper on the brake pad will be reduced, which will lead to the deterioration of the braking performance of the bicycle disc brake and increase the distance when braking, making the Bicycles have major safety hazards during normal riding
