Embodiment Construction

[0046] In the different figures, identical components are always provided with the same reference numerals and are therefore usually only mentioned and explained once in each case.

[0047] exist figure 1 In , a first embodiment of a powertrain system 1 is shown, which may be used in a hybrid motor vehicle. The drivetrain 1 has an internal combustion engine 2 , a transmission 3 , an electric machine 4 and a disconnect clutch 5 . As will be described further below, in the closed state of the separating clutch 5 a force transmission between the electric machine 4 and the internal combustion engine 2 can take place. In the disengaged state of the separating clutch 5 , the electric machine 4 and the internal combustion engine 2 are decoupled from each other.

[0048] The internal combustion engine 2 has an output shaft 2 . 1 , which is connected without a clutch to a first transmission input shaft 10 of the transmission 3 . This means that the output shaft 2.1 is permanently op...

Abstract

The invention relates to a drive train for a motor vehicle, having an internal combustion engine (2), having an automated change-speed transmission (3), having an electric machine (4) with a switchable separating clutch (5) for selectively making a power flow possible between the electric machine (4) and the internal combustion engine (2), and having a differential gear mechanism (20), wherein theinternal combustion engine (2) has an output shaft (2.1) which is coupled without a separating clutch to a first transmission input shaft (10) of the automated change-speed transmission (3), whereinthe automated change-speed transmission (3) has a first transmission output shaft (11) and a second transmission output shaft (12) which are operatively connected to a differential drive gear (19) ofthe differential gear mechanism (20), wherein the separating clutch (5) is arranged coaxially with respect to a clutch shaft (15) which is connected to the separating clutch (5) and is arranged spacedapart in parallel from the first transmission input shaft (10), wherein the clutch shaft (15) is arranged spaced apart in parallel from the first transmission output shaft (11) and the second transmission output shaft (12).

Description

technical field [0001] The invention relates to a drive train for a motor vehicle with an internal combustion engine, an automatic transmission, an electric machine, a switchable separating clutch for selectively enabling a force transmission between the electric machine and the internal combustion engine, and a differential, Therein, the internal combustion engine has a driven shaft which is coupled without a clutch to a first transmission input shaft of the transmission, wherein the automatic transmission has a first transmission input shaft which is operatively connected to the differential drive wheels of the differential and Second transmission output shaft. [0002] Furthermore, the invention relates to a method for operating a drive train of this type. Background technique [0003] Such drivetrains are also referred to as hybrid drivetrains and can be used in motor vehicles, for example passenger cars. [0004] From document DE 10 2014 222 587 A1 a drive train is kn...
