Title: BRAKE LINKAGE SYSTEM HAVING LARGE VARIABLE BRAKE RATIO RANGE
Abstract:
A brake linkage system having a large variable brake ratio range, comprising: a main body (20), a connecting rod piece (30), a swing arm assembly (40) and a pull rod assembly (50). The main body (20) provides connection with left and right handle pull cables and front and rear brake cables. The connecting rod piece (30) is connected with the right handle pull cable and the front brake cable. The swing arm assembly (40) comprises a base (41), a swing arm (42) and a first linkage piece (43), wherein the swing arm (42) includes a brake ratio control sliding surface (421), a sliding groove (422) and a guiding portion (423), and the sliding groove (422) is provided with a pin rod (425) connecting an elastic component (424). The pull rod assembly (50) comprises a socket (51) and a pull rod (52), wherein the socket (51) is connected with the left handle pull cable, and one end of the pull rod (52) is pivoted with the socket (51), and the other end of the pull rod (52) is provided with a sliding portion (521) striding on the brake ratio control sliding surface (421). When the pull rod (52) is pulled to reach a set strength, the sliding portion (521) moves along a downward direction of the brake ratio control sliding surface (421) to a balance position corresponding to a pull force value of the left handle pull cable, so that a distributing ratio of braking force of front and rear wheels is changed.
