A fine-tuning disc brake caliper

Abstract

The invention relates to a fine-tuning disc brake caliper. The caliper main body (18) has a rope-tightening adjustment part and a support part. The two ends of the caliper main body (18) are provided with fine-tuning devices and protective covers, and the support part is a rocker arm (15). , the fine-tuning device is composed of an external adjustment device connected to the tight rope adjustment part and an internal adjustment device connected to the cover plate (22). One end of the main body of the caliper (18) is also provided with a brake drive assembly. The first lever (4 ) is in contact with the driving push rod (20); the second locking piece (3) is in contact with the cover plate (22), and the first locking piece and the second locking piece are adjusted with the disc brake on the bicycle through the fine-tuning device. The distance between the pads can be adjusted on three sides of the disc brake, so as to solve the inconvenience caused by the loading, more fast and stable loading and debugging, fine-tuning on both sides can minimize the gap between the pad and the disc brake pad in the future, and can achieve The problem of moving the best state prolongs the service life of the pad.

Description

technical field [0001] The invention relates to a mechanical disc brake device, in particular to a bicycle disc brake caliper capable of adjusting the braking distance. Background technique [0002] At present, the bicycle disc brakes involved rely on the pulling force of the brake line to make the brake pads in the caliper rub against and clamp the disc to produce a braking effect. A caliper is installed on the fork and the frame, and the disc is clamped through the brake block in the caliper to achieve the purpose of braking. It has become the mainstream of the motorcycle braking system; After improvements in reliability and other aspects, disc brakes are becoming more and more popular among consumers, and may become standard equipment for most bicycles. While becoming the standard, how to improve the braking effect has become the key to safety and quality. In the existing disc brake spacing adjustment mechanism, it is difficult to install and debug the disc brake, and th...

[0002] At present, the bicycle disc brakes involved rely on the pulling force of the brake line to make the brake pads in the caliper rub against and clamp the disc to produce a braking effect. A caliper is installed on the fork and the frame, and the disc is clamped through the brake block in the caliper to achieve the purpose of braking. It has become the mainstream of the motorcycle braking system; After improvements in reliability and other aspects, disc brakes are becoming more and more popular among consumers, and may become standard equipment for most bicycles. While becoming the standard, how to improve the braking effect has become the key to safety and quality. In the existing disc brake spacing adjustment mechanism, it is difficult to install and debug the disc brake, and the gap is large. Due to the uneven thrust of the disc brake, the inability to guarantee the installation accuracy of the disc brake, and the quality and wear of the brake pads, the braking effect is not good. The distance between the pad and the brake disc cannot be adjusted accurately. It is difficult to clamp the disc brake pad with two pads at the same time and at the same time. In the end, the brake pad will not completely fail when the pad is used up. Therefore, it is necessary to adjust the two brake pads. Adjust the front and rear spacing of the discs so that the disc is in the middle of the two discs, so how to adjust the distance between the discs to the minimum distance to achieve the best braking state has become an urgent problem to be solved
