The invention discloses an electric driving system, a power system of an electric automobile and the electric automobile. The electric driving system comprises a box body, a driving motor, a first planet row, a second planet row, a differential mechanism and a gear shifting mechanism, and the first planet row comprises a first sun gear, a first planet gear and a first gear ring; the second planet row comprises a second sun gear, a second planet gear structure and a second gear ring; the gear shifting mechanism comprises a gear moving switching mechanism and a clutch. According to the electric driving system provided by the invention, the gear movable switching mechanism is matched with the clutch, so that the electric driving system can output two rotating speeds, namely, the electric driving system has two gears so as to better adapt to complex road conditions, and the electric driving system adopts the first planet row and the second planet row to realize power transmission; the planet row is compact in structure and small in occupied space, and the gear movable switching mechanism and the clutch are simple in structure and small in size, so that the whole electric driving system is more compact in structure, small in space needed by arrangement and better in adaptability.

    本发明公开一种电驱动系统、电动汽车的动力系统及电动汽车,电驱动系统包括箱体、驱动电机、第一行星排、第二行星排、差速器和换挡机构,第一行星排包括第一太阳轮、第一行星轮和第一齿圈;第二行星排包括第二太阳轮、第二行星轮结构和第二齿圈;换挡机构包括齿轮活动切换机构和离合器。本发明提供的电驱动系统,通过齿轮活动切换机构和离合器的配合,以使电驱动系统可输出两种转速,即电驱动系统具有两个档位以能够更好适应复杂路况,电驱动系统采用第一行星排和第二行星排实现动力传输,行星排的结构紧凑、空间占用小,且齿轮活动切换机构和离合器的结构较简单体积小,从而使整个电驱动系统的结构更紧凑,布置所需空间小,具有更好的适应性。
