The invention discloses an electric driving system, a power system and an electric vehicle. The electric driving system comprises a box body, a driving motor, a gear shifting gear assembly and a differential mechanism. The driving motor is provided with a motor output shaft; the gear shifting gear assembly comprises a first-gear driving gear and a second-gear driving gear. The differential mechanism comprises a differential mechanism shell and two half shaft output gears, a first driven gear and a second driven gear are arranged on the differential mechanism shell, and the first driven gear and the second driven gear are correspondingly meshed with the first-gear driving gear and the second-gear driving gear respectively; wherein the first-gear driving gear and the second-gear driving gear can be switched to be in driving connection with the output shaft of the motor, so that the output shaft of the motor is switched to be in driving connection with the first driven gear and the second driven gear, and correspondingly, the electric driving system has a first-gear working mode and a second-gear working mode. The invention aims to solve the problems that an existing electric driving system is large in occupied space, not compact enough in structure, low in integration level and low in adaptability.

    本发明公开一种电驱动系统、动力系统以及电动汽车,电驱动系统包括箱体、驱动电机、换档齿轮组件和差速机构;驱动电机具有电机输出轴;换档齿轮组件包括一档主动齿轮和二档主动齿轮;差速机构包括差速器壳体以及两个半轴输出齿轮,在差速器壳体上设有第一从动齿轮和第二从动齿轮,第一从动齿轮和第二从动齿轮分别对应与一档主动齿轮和二档主动齿轮啮合;其中,一档主动齿轮和二档主动齿轮能够切换驱动连接于电机输出轴,以使得电机输出轴切换驱动连接第一从动齿轮和第二从动齿轮,对应的,电驱动系统具有一档工作模式和二档工作模式。本发明旨在解决现有电驱动系统占用空间较大、结构不够紧凑、集成度低、适配度低的问题。
