Drive train for a hybrid vehicle
First Claim
1. A drive train (1, 30) for a hybrid vehicle, the drive train having an internal combustion engine (2) connected to an input side of a disengagement clutch (4), an output side of the disengagement clutch (4) being permanently connected to a first end of a continuous transmission input shaft (7), a second end of the continuous transmission input shaft being permanently connected to an input element (8, 38) of an automatic transmission (17, 36), an electric machine (5) being connected to the continuous transmission input shaft (7) for driving the continuous transmission input shaft (7), a hydraulic pump (6) being arranged down stream of the disengagement clutch (4) and before a shiftable starting element (F) of the automatic transmission (17, 36) and driven by the continuous transmission input shaft, so that when the disengagement clutch (4) and the starting element (F) are both disengaged and the electric machine (5) is operating, only the continuous transmission input shaft (7), the input element (8, 38) of the automatic transmission (17, 36) and the hydraulic pump (6) are driven by the electric machine (5).

Abstract
A drive train (1, 30) for a hybrid vehicle, in which an internal combustion engine (2) is drive-technologically connected to a disengagement clutch (4) whose output side is connected to a transmission input shaft (7), which is connected to an input element (8, 38) of an automatic transmission (17, 36), and in which the transmission input shaft (7) can be driven by an electric machine (5) and itself drives a hydraulic pump (6), which is drive-technologically arranged after the disengagement clutch (4) and before a shiftable starting element (F) of the automatic transmission (17, 36).

20. A hybrid vehicle drive train (1, 30) having an internal combustion engine (2) connected to an input side of a disengagement clutch (4) via an oscillation damper and an output side of the disengagement clutch (4) being directly connected to a first end of a transmission input shaft (7) which is directly connected to an input element (8, 38) of an automatic transmission (17, 36), an electric machine (5) is coupled to the transmission input shaft (7) for at least one of the driving and being driven by the transmission input shaft (7), and a hydraulic pump (6) being arranged after the disengagement clutch (4) but before a shiftable starting element (F) of the automatic transmission (17, 36) and driven by the transmission input shaft, so that when the disengagement clutch (4) and the starting element (F) are disengaged and the electric machine (5) is operated, only the transmission input shaft (7), the input element (8, 38) of the automatic transmission (17, 36) and the hydraulic pump (6) are driven by the electric machine (5) without any other automatic transmission element being driven by the electric machine (5).
