The invention relates to a drive unit for an electric vehicle and a drive axle with the drive unit. The drive unit comprises an electric machine (EM) and a three-speed shift transmission with a firstshift element (A), a second shift element (B), a third shift element (C), and first and second planetary sets which are couple to each other; the first planetary set (PS1) has a first sun shaft, a first ring gear shaft (HR1) and a first carrier shaft, and the second planetary set has a second sun shaft (SO2), a second ring gear shaft, and a second carrier shaft; the first carrier shaft (ST1) is fixedly connected to the second ring gear shaft (HR2), the first sun shaft (SO1) is drivable by the electric machine (EM), the first ring gear shaft (HR1) is positionally fixed, wherein a driven end isrealized via the second carrier shaft (ST2); and the first shift element (A) is actuatable to engage a first gear, the second shift element (B) is actuatable to engage a second gear, and the third shift element (C) is actuatable to engage a third gear.

    本发明涉及用于电动车辆的驱动单元和具有驱动单元的驱动车桥。该驱动单元包括电机(EM)和具有第一切换元件(A)、第二切换元件(B)、第三切换元件(C)和两个彼此联接的行星齿轮组的三挡换挡变速器,第一行星齿轮组(PS1)具有第一太阳轴、第一齿圈轴(HR1)和第一行星架轴,第二行星齿轮组具有第二太阳轴(SO2)、第二齿圈轴的和第二行星架轴,第一行星架轴(ST1)固定地与第二齿圈轴(HR2)连接,第一太阳轴(SO1)能通过电机(EM)驱动,第一齿圈轴(HR1)保持固定,其中,从动端经由第二行星架轴(ST2)实现,为了切换第一挡能操纵第一切换元件(A),为了切换第二挡能操纵第二切换元件(B)并且为了切换第三挡能操纵第三切换元件(C)。
