The invention relates to an electric drive (1) for a motor vehicle, comprising: an electric machine (2) having a rotor (3); a planetary gear stage (13) comprising a sun gear (11), a planet carrier (8) with planet gears (10) and a ring gear (12); a switchable one-way clutch (20) comprising a first clutch half (21), a second clutch half (22), a switching member (25) and an actuator (26), the first clutch half (21) being connected to the housing (5) in a rotationally fixed manner. The electric drive is characterized in that the second clutch half (22) is connected in a rotationally fixed manner to the ring gear (12), and in that the engagement element (24) is connected in a rotationally fixed manner to the ring gear (12) and in a rotationally fixed manner to the second clutch half (22) and is arranged radially with respect to the rotational axis (A) of the planetary gear stage (13) between a sun gear tooth row of the sun gear (11) and a ring gear tooth row of the ring gear (12).
本发明涉及一种机动车用电驱动装置(1),具有:带有转子(3)的电机(2);行星传动级(13),其包括中心齿轮(11)、带有行星齿轮(10)的行星齿轮架(8)和齿圈(12);可切换的单向离合器(20),可切换的单向离合器包括第一离合器半体(21)、第二离合器半体(22)、切换件(25)和致动器(26),其中,第一离合器半体(21)抗旋转地连接至壳体(5)。电驱动装置的特点是,第二离合器半体(22)抗旋转地连接至齿圈(12),其中,接合件(24)抗旋转地连接至齿圈(12)且抗旋转地连接至第二离合器半体(22),并且关于行星传动级(13)的转动轴线(A)在径向上布置在中心齿轮(11)的中心齿轮齿列与齿圈(12)的齿圈齿列之间。
