Fine adjustment type disc brake calipers

Abstract

The invention relates to a pair of fine adjustment type disc brake calipers. A caliper body (18) comprises a rope tightening adjusting portion and a supporting portion, a fine adjustment device and a protective cover are arranged at the two ends of the caliper body (18) respectively, a rocker arm (15) serves as the supporting portion, the fine adjustment device is composed of an outer adjustment device connected to the rope tightening adjusting portion, and an inner adjustment device connected to a cover plate (22), a brake driving assembly is further arranged at one end of the caliper body (18), a first brake pad (4) abuts against a driving ejector rod (20), and a second brake pad (3) abuts against the cover plate (22). The separation distance between the first brake pad and a disc brake block on a bicycle and the separation distance between the second brake pad and the disc brake block on the bicycle can be adjusted through the fine adjustment device, inconvenience caused by bicycle assembly is eliminated through three-side adjustment of a disc brake, bicycle assembly and bicycle debugging can be carried out more rapidly and more stably, the gap between each brake pad and the disc brake block can be adjusted to be minimum through two-side fine adjustment, the optimal state of braking can be achieved, and the service life of each brake pad is prolonged.

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
