驱动装置
摘要：
一种驱动装置，具有：旋转电机(MG1)、在旋转电机(MG1)的径向内侧与该旋转电机(MG1)在轴向上重叠配置的行星齿轮装置(P1)、贯通行星齿轮装置(P1)的太阳轮(s1)的径向内侧的贯通轴(I)、容置旋转电机(MG1)和行星齿轮装置(P1)的壳体(DC)，贯通轴(I)相对于行星齿轮装置(P1)在轴向两侧支撑于壳体(DC)，旋转电机(MG1)的转子(Ro1)与太阳轮(s1)一体联结，并且在轴向的两个位置上可旋转地被支撑，在该两个位置中的一个位置上，转子(Ro1)被支撑于壳体(DC)，在另一个位置上，转子(Ro1)在太阳轮(s1)的径向内侧支撑于被贯通轴(I)。
摘要（英）：

A drive device includes a rotating electrical machine; a planetary gear unit positioned radially inside the rotating electrical machine so as to axially overlap the rotating electrical machine; a through shaft extending radially inside and through a sun gear of the planetary gear unit; and a case that accommodates the rotating electrical machine and the planetary gear unit. The through shaft is supported by the case on both axial sides of the planetary gear unit, and a rotor of the rotating electrical machine is connected integrally with the sun gear and is rotatably supported at two axial positions, the rotor is supported at a first axial position of the two axial positions by the case, and the rotor is supported at a second axial position of the two axial positions at a position radially inside the sun gear by the through shaft.
