Embodiment Construction

[0053] figure 1 A first embodiment of a drive train 2 for a motor vehicle according to the invention is shown. The drive train 2 has an engine 4 which in the present case is designed as an internal combustion engine. figure 1 Only a motor housing 6 of the motor 4 and a drivable motor shaft 8 are shown. The motor shaft 8 , which is rotatable about a rotational axis 10 , extends on one side in a first axial direction 12 and on the other side in a second axial direction 14 opposite to the first axial direction 12 .

[0054] The drive train 2 also includes a transmission 16, which is only figure 1 is schematically indicated. The transmission 16 has a transmission input shaft 18 which is in rotational driving connection with a first end 22 of the motor shaft 8 via a connection arrangement 20 indicated only schematically, wherein the first end 22 of the motor shaft 8 points towards the first Axial direction 12. The transmission 16 and / or the connection arrangement 20 are arrang...

Abstract

The present invention relates to a drivetrain for a motor vehicle, compries an electric machine which can be operated in a generator mode and a starter mode; a planetary gear set, of which a first element, which forms the drive input side of the planetary gear set in the generator mode and forms the drive output side of the planetary gear set in the starter mode, is in rotationally driving connection with the engine shaft, a second element, which forms the drive output side of the planetary gear set in the generator mode and forms the drive input side of the planetary gear set in the starter mode, is in rotationally driving connection with the rotor, and a third element, which can be fixed by means of a first actuating device to a stationary housing in the starter mode, with a second actuating device also being provided which, in the generator mode, interacts with at least one of the elements in such a way that the planetary gear set performs a block rotation. The planetary gear set is arranged in front of the engine in the first axial direction, while the transmission is arranged behind the engine in the first axial direction.

Description

technical field [0001] The invention relates to a drive train for a motor vehicle having an engine with a drivable engine shaft; a transmission with a transmission input shaft in rotational driving connection with the engine shaft; An electric machine operable in a generator mode as well as in a starter mode; and having a planetary gear set having three elements, specifically a sun gear, with multiple A planet carrier of planetary gears, a first member of the planetary gear set is in rotational driving connection with the engine shaft, a second member is in rotational driving connection with the rotor, and a third member of the planetary gear set Can be fixed to a stationary housing by a first actuating device, wherein a second actuating device is also provided which can interact with at least one of these elements in such a way that the The planetary gear sets perform a block rotation. Background technique [0002] DE 101 02 015 A1 discloses a drive train of this kind. T...
