Problems solved by technology

However, in this structural form, the two arm components of the brake cannot swing synchronously to clamp the rim, so that there will be a time difference when the two arm components clamp the two sides of the rim respectively, resulting in inconsistent braking actions and ineffective braking. Especially when braking, the force will be heavier on one side, which will cause excessive wear on the brake pads on one side in the long run, which will affect the subsequent braking performance and even cause brake failure.
Furthermore, since the braking action mode is to press the rim step by step with one side first, and then clamp the rim with both sides together, during the time from one side to both sides to clamp the rim together, it is impossible to immediately and directly brake to cope with it. Stopping in an emergency situation is quite dangerous for the rider, therefore, the structural design of the existing bicycle brakes is poor and still needs to be improved

Abstract

A bicycle brake us disclosed. The bicycle brake includes a base fixedly connected to a preset position of a bicycle frame at least through a fixing bar, and extending downward to form a first extending arm and a second extending arm. The first and second extending arms are at two sides of a rim correspondingly. Lower ends of the first and second extending arms are pivoted to lower ends of first and second clamping arms respectively. One side and an edge side of the upper end of the first clamping arm are fixedly connected to a fixing member and a wire hole member respectively. The upper end ofthe second clamping arm is pivoted to a pulley at the fixing member side. The first and second clamping arms are bonded to braking members respectively. Accordingly, the braking members can be abutted against two sides of the rim in a synchronous and balanced manner, coincident braking actions are achieved so that effective braking is achieved, and the assembling cost and machining cost when braking members are mounted to a bicycle frame are reduced.

Description

technical field [0001] The invention relates to a bicycle brake, in particular to a brake which clamps a bicycle rim and generates friction to slow down or stop the running rim. Background technique [0002] (1) As shown in Taiwan's new patent certificate Nos. M359498 and M342332, the bicycle brake consists of the top of the inverted V-shaped fixed piece and the convex post at the bottom of the inverted V-shaped two wings, which are screwed to the fork tube on the frame. (as shown in M359498), it is even more necessary to incorporate a clamp behind the inverted vee plate for coupling to the bifurcation tube on the frame (as shown in M342332); therefore, in order to couple the brake to the frame The bifurcated tube on the frame needs to be processed separately or screw holes are formed for the installation and fixing of the brake, which not only increases the processing cost of the frame, but also increases the cost of brake installation and parts. (2), another known outer b...
