Brake operatiing device for interlocking brake system

Abstract

The present invention relates to a brake operating device for an interlocking brake system, which includes a first brake operating device and an interlocking wire. The first brake operating device includes a first brake handle, a first lever, a first cylinder, a first plunger and a first spring. The first plunger and the first spring are accommodated in the first cylinder. The first spring connects the first plunger and the first cylinder, and exerts a spring force on the first plunger for a long time. The first brake handle is pivotally connected to the first lever and has a first end. The first lever is pivotally connected to the first cylinder. When the first lever rotates, it can push the first plunger to move. The interlocking wire includes a sleeve and an inner wire passed through the sleeve. One end of the inner wire is connected to the first end, and the other end of the inner wire is connected to a second brake operating device. Wherein, the first end can resist the first cylinder or an overlapping member on the first cylinder, and the first end can drive the inner wire to act. As such, on the premise that better interlocking brake actuation logic can be achieved, the rider will not have to operate the first brake lever with any effort, which is indeed an optimized design.
