The invention discloses a brake mechanism with a length compensation function. The brake mechanism comprises a frame, a handle mounted at one end of the frame, a brake handle movably mounted on the handle, a brake pad movably mounted on the frame and a brake cable, wherein one end of the brake cable is connected with the brake handle, and the other end of the brake cable is connected with the brake pad; the device is characterized by further comprising a compensation mechanism which is arranged on the frame and used for compensating the length of the brake cable, the compensation mechanism comprises a floating wheel installed on the frame in a floating mode, a fixing rod installed on the frame and a connecting piece which is connected with the fixing rod and the floating wheel and has elasticity, and the brake cable is wound on the floating wheel by at least one circle. Through the arrangement of the compensation mechanism, when tension is applied to the brake cable in the folding process of the four-wheeler and the brake cable needs to be lengthened, the length of the brake cable is automatically compensated, and when length compensation is not needed, the redundant brake cable is automatically wound, so that the redundant brake cable is prevented from being extruded, bent and blocked in the frame to affect braking.
本发明公开了一种具有长度补偿功能的刹车机构,包括车架、安装在车架一端的手柄、活动安装在手柄上的刹车把手、活动安装在车架上的刹车片以及一端与刹车把手连接,另一端与刹车片连接的刹车线;其特征是还包括设置在车架上对刹车线长度起补偿作用的补偿机构,所述的补偿机构包含浮动安装在车架的浮动轮、安装在车架上的固定杆以及连接固定杆和浮动轮且具有弹力的连接件,刹车线在浮动轮上至少绕有一圈。该发明通过补偿机构的设置,在四轮车进行折叠过程中对刹车线施加拉力需要刹车线拉长时,刹车线长度自动进行长度补偿,在无需长度补偿时自动对多余的刹车线进行收卷而不会使多余的刹车线挤压折弯的堆堵在车架内而影响刹车。
