    摘要： A drive unit for an electric vehicle, having an electric machine and a three-speed shift transmission with first, second and third shift elements, and two planetary sets which are coupled with each other. The first planetary set has a first sun gear shaft, first ring gear shaft and a first carrier shaft. The second planetary set has a second sun gear shaft, a second ring gear shaft and second carrier shaft. The first carrier shaft is fixed to the second ring gear shaft. The first sun gear shaft can be driven by an electric machine. The first ring gear shaft is fixed and output takes place via the second carrier shaft. The first shift elements are actuated to engage a first gear, the second shift elements are actuated to engage the second gear and the third shift elements are actuated to engage the third gear.

    摘要： A stator (1a, 1 b) for an electric machine. The stator (1a, 1b) is fixedly mounted relative to a rotational axis (Rot). The stator (1a, 1b) comprises a stator yoke (2) that extends in the axial (A) and radial (R) directions. Stator teeth (3), facing toward the rotational axis (Rot), are arranged in a ring shape on the stator yoke (2). The teeth are uniformly spaced apart from one another so that a stator groove (14) is formed therebetween. The stator (1a, 1b) is divided into a first stator section (5) and a second stator section (6). First and second outer walls (9, 10) are provided on the stator yoke (2) and serve to axially support the stator yoke (2). A cooling manifold disk (11) is integrated between the first stator section (5) and the second stator section (6). An electric machine with a stator of that type is also disclosed.

    摘要： A transmission having planetary gearsets (RS1, RS2, RS3, RS4, RS5). Elements (ST2, ST4) of gearsets (RS2, RS4) form input and output shafts, respectively. Element (SO1) of gearset (RS1) couples element (HO5) of gearset (RS5) and can be immobilized by shift element (A). Element (ST1) of gearset (RS1) couples element (HO4) of gearset (RS4). Element (HO1) of gearset (RS1) can be immobilized by shift element (B). Elements (SO4, ST2) of gearsets (RS4 RS2) can connect by shift element (C). Elements (HO2, SO3, SO5) of gearsets (RS2, RS3, RS5) couple and can couple element (SO4) of gearset (RS4) by shift element (E). An element of gearset (RS4) is connected to an element of gearset (RS3), while another element of gearset (RS4) can be connected by shift element (D) to another element of gearset (RS3). Elements (SO2 ST5) of gearsets (RS2, RS5) are connected and can be immobilized by shift element (F).

    摘要： A device for a drive train of a hybrid vehicle having a planetary gear set (4) including a ring gear (9), a sun gear (10) and a carrier (8). A first element of these elements of the planetary gear set serves as the connection to a transmission input shaft (11) of a transmission (3) and a second element of these elements of the planetary gear set serves as the connection to an electric machine (2) of a hybrid drive. A clutch (5) and associated shift element (6) by which, in a first shift position (A), a third element of the planetary gear set can be coupled to an internal combustion engine (1) of the hybrid drive while in a second shift position (B), can be coupled to one of the other elements of the planetary gear set (4).
