The invention discloses a gearbox, an electric drive system and an electric automobile. The gearbox comprises a box body, a first planet row, a second planet row, a third planet row, a first clutch, asecond clutch and a differential mechanism, wherein the first planet row, the second planet row and the third planet row are arranged in the box body; a sun gear of the first planet row is used for being connected with a power input shaft, and a planet carrier of the second planet row is connected with a sun gear of the third planet row; the first clutch is arranged between a planet carrier of the first planet row and a sun gear of the second planet row; the second clutch is arranged between the sun gear of the first planet row and the sun gear of the second planet row; a planet carrier of the third planet row is connected with the differential mechanism; and a power output shaft at one end of the differential mechanism extends in the direction of sequentially penetrating through the centers of the sun gears of the third planet row, the second planet row and the first planet row. The axis of the power input shaft of the gearbox coincides with the axis of the power output shaft of thegearbox, the structure is compact, and the space size can be reduced more easily.

    本发明公开了一种变速箱、电驱系统及电动汽车,所述变速箱包括:箱体;设于所述箱体内的第一行星排、第二行星排、及第三行星排;所述第一行星排的太阳轮用于连接动力输入轴,所述第二行星排的行星架连接所述第三行星排的太阳轮;第一离合器,设于所述第一行星排的行星架与所述第二行星排的太阳轮之间;第二离合器,设于所述第一行星排的太阳轮与所述第二行星排的太阳轮之间;差速器,所述第三行星排的行星架连接所述差速器;所述差速器一端的动力输出轴沿依次穿过所述第三行星排、第二行星排、第一行星排的太阳轮中心的方向延伸。该变速箱的动力输入轴与动力输出轴轴线重合,结构紧凑,更加有利于减少空间尺寸。
