Problems solved by technology

[0004] In order to solve the problems of low braking performance of existing bicycle disc brake devices and complex installation and adjustment during use, the present invention proposes a double-acting bicycle disc brake device, which can realize simultaneous extrusion on both sides of the disc, In this way, double-action and synchronous braking are realized, which improves the braking efficiency, ensures the force balance of the disc, and avoids the problem of easy deformation of the brake disc for a long time; at the same time, the device has brake pad position adjustment devices on the left and right sides, It makes the operation of adjusting the distance between the device and the disc disc simple and easy under the condition of installation and brake pad wear

Embodiment Construction

[0021] This embodiment will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a double-acting bicycle disc brake device 4 is installed on the front fork 1 through mounting screws 2, and the outer circular surface of the disc 5 extends into the disc opening 3 on the device 4 for accommodating the disc 5, and the disc The end faces on both sides of the disc 5 are at the same distance from the two ends of the disc opening 3 .

[0023] Such as figure 2 , image 3 As shown, the housing 10 is similar to a cylinder, on which there are disc openings 3 for accommodating the disc, threaded holes 7 for mounting with the vehicle frame, and cable holes 6 for fixing the brake cables. There is an axis and the disc in the housing 10 The direction of the opening 3 is perpendicular to the cylindrical through hole 8 with a rectangular groove 9; the through hole 8 is a stepped hole, and the brake pads are installed in the stepped h...

Abstract

The invention relates to a double-acting bicycle disk brake device and belongs to the field of design and manufacturing of bicycle part products. The double-acting bicycle disk brake device consists of a shell, a double-acting brake mechanism and brake pad position regulating mechanisms. The double-acting bicycle disk brake device is arranged on a disk brake seat of a bicycle frame and a front fork and can synchronously extrude two sides of a disk, so that double acting and synchronous brake can be realized, brake efficiency is improved, the disk can be forced uniformly, and the problem that the brake disk is easy to deform after being used for a long time is solved. Meanwhile, the double-acting bicycle disk brake device is provided with brake pad position regulating devices which are arranged on the left and right sides, so that distance between the device and the disk can be regulated simply and easily under the conditions that the disk brake device is installed and brake pads are abraded.

Description

technical field [0001] The invention relates to a bicycle disc brake device, in particular to a disc brake device capable of performing double-action and synchronous braking on both sides of a bicycle disc, which belongs to the field of product design and manufacture of bicycle parts. Background technique [0002] In order to achieve efficient and fast braking of bicycles, disc brakes have replaced traditional drum and rim brakes, and are increasingly used on various bicycles, especially various sports bicycles. [0003] At present, most of the disc brakes used are based on the principle of single-action braking. For example, the bicycle disc brake structure proposed by Chinese Patent No. 201020259012.3 has low braking efficiency and uneven distribution of braking force. The braking will cause the disc to deform under the condition of high temperature and uneven force, which seriously affects the braking performance; at the same time, it only has the function of adjusting th...
