Description

Fixed structure of bicycle disc caliper

This creation is about a bicycle and locomotive disc raking device, especially its disc caliper fixing structure, which can accurately position the disc caliper without yaw.

According to the conventional caliper fixing structure 7, as shown in FIG. 5, the caliper 71 and an adapter 75 are fixed to the front fork 73 of the bicycle by two sets of fixing members 72, and the caliper 71 is mounted on a disc. The outer periphery of the cymbal 74 is mechanically or hydraulically biased by a brake in the caliper 71 to allow the brake to clamp the sides of the disc 74 to achieve the effect of braking. .

The fixing member 72 used earlier is a screw 721, a spacer 722, and an elastic 723. The front end of the screw 721 extends through the fixing hole 711 of the spacer 722, the elastic 723, and the caliper 71, respectively. A screw is locked to the front fork 73.

However, the fixing member 72 has many defects, one of which is that the screw 721 is pressed against the spacer 722 and the elastic washer 723 to be flatly attached to the top surface of the corresponding caliper 71, when the screw 721 is locked. The caliper 71 is deflected and the positioning thereof is not accurate enough, so that the gap between the squeegee 71 and the squeegee 74 on both sides of the caliper 71 is uneven, thereby affecting the braking effect. The second is that the spacer 722 and the elastic washer 723 often interfere with the accuracy of the fixed positioning of the caliper 71.

In order to solve the lack of the fixing member 72, another manufacturer has developed another conventional caliper fixing structure 8, and the fixing member 82 is provided with a screw 821 and an outer arc portion 824 at the bottom of the head, as shown in FIG. As shown, the caliper 81 is provided with a concave arc portion 812 corresponding to the outer arc portion 824, and the outer arc portion 824 and the concave arc portion 812 function to lock the bottom surface of the caliper 81 when the screw 821 is locked. When attached to the bicycle front fork 83, there is no deflection, so that the caliper 81 can be accurately positioned. However, this function cannot adjust the function of the installation position of the caliper 81, and thus its function is greatly reduced.

Therefore, in response to the above problems, the creator has developed a conventional caliper fixing structure 9 of the domestic new patent No. M466835 "disc 煞 caliper fixing structure", as shown in Fig. 7, the conventional two shims are improved, that is, The top end of the two spacers 93 is provided with a concave arc portion 931, and the bottom ends of the two spacers 93 respectively extend downwardly with two pins 932. When the two bolts 92 respectively penetrate the two spacers 93 and screw the caliper 91 When the bicycle fork is locked, the two pins 932 are fitted into the corresponding elliptical long holes 911 of the caliper 91, and the outer arc portions 922 of the bolts 92 are abutted against the recesses of the spacers 93. The arc portion 931 prevents the washer pad 93 from rotating relative to the elliptical slot 911 of the disc caliper 91 by the two pins 932, thereby improving the accuracy of the caliper 91 installation. However, since the two pins 932 of the spacers 93 are fitted into the elliptical long holes 911 of the caliper 91, since the elliptical long holes 911 have a fixed length, the space for the calipers 91 to be finely adjusted is very limited.

In view of the above problems of the fixed structure of the disc caliper, the creator further studies and develops the solution, so the main purpose of the creation is to provide an anti-rotation set screw set, and to improve the caliper when the lock is used. The problem of angle yaw and inaccurate positioning can improve the fixing precision of the disc caliper and the fine adjustment range, and can shorten the fixing structure of the bicycle caliper and the caliper installation adjustment time.
