Abstract
A drive train for a motor vehicle, in particular a hybrid vehicle, having a drive shaft that can be connected to an internal combustion engine, and a transmission oil pump that can be coupled to the drive shaft by means of a switchable freewheel. An electrical machine for driving the transmission oil pump is also provided and is arranged in the power flow direction between the drive shaft and the transmission oil pump, and is in parallel to the freewheel in the power flow direction. A second freewheel is unnecessary and thereby reduces the construction space needed for the power train.
