The invention discloses a speed-changing gear box which comprises a box body shell. The power input shaft and the power output shaft are rotatably connected with the box body shell in a penetrating manner; a gear set; wherein the gear set is divided into a plurality of relatively independent units with different transmission ratios, each unit comprises an input half shaft, an output half shaft, a brake gear and a brake assembly, the brake gear is coaxially and rotatably connected with the output half shaft in a sleeving manner, and the brake assembly is used for braking the brake gear of the corresponding unit when the corresponding unit becomes a power output line; the pair of planetary gears, the first half axle gear, the pair of planetary gears and the second half axle gear are sequentially meshed. Compared with an existing mainstream gearbox, gears of the output rotating speed can be switched without a clutch, damage is not prone to occurring, and the pause feeling of gear switching operation is relieved.

    本发明公开了一种齿轮变速箱,包括:箱体壳;转动穿接箱体壳的动力输入轴和动力输出轴;齿轮组;其中,齿轮组分为若干相对独立的、传动比不一的单元,每一单元包括输入半轴、输出半轴、制动齿轮及制动组件,制动齿轮同轴旋转地套接输出半轴,制动组件在相应单元成为动力输出线路时用于对相应单元的制动齿轮进行制动;一对行星齿轮,半轴齿轮一、一对行星齿轮、半轴齿轮二依次啮合。与现有的主流变速箱相比,无需离合器即可切换输出转速的档位,不易损坏,减轻了档位切换操作的顿挫感。
