<p>The invention relates to a drive system for a motor vehicle, comprising a starter and generator unit (1) that is arranged in a drive train with a drive shaft (6). Said starter and generator unit (1) has an electric machine (8, 9), which can be operated as an electric motor with a starter function or as an electric generator, and a planetary gear (10) comprising at least one sun wheel (16, 28), at least one planet wheel (17, 17') and at least one ring gear (18, 27). Said planetary gear (10) can be connected to the electric machine (8, 9), to the drive wheel (6) and to a housing (3, 4) of an aggregate (2) that is located in the drive train, by means of shafts (12, 13, 31) and control elements (14, 15, 15', 15', 15'', 29, 30, 32, 34, 36 to 41), in such a way that a transmission (i) greater than 1 can be set in a starting mode, and a transmission (i) equal to 1 can be set in a generator mode. The starter and generator unit (1) is located in the housing (3, 4) in an area in which the drive shaft (6) or a shaft (5) that is rotationally fixed thereto, penetrates said housing (3, 4), in a sealed manner in relation an area surrounding the housing (3, 4).</p> |
