US Patent 8968137 Motor vehicle drive train

Drive train for a motor vehicle, having an electric machine for providing motive power, and a transmission arrangement. The transmission arrangement has a transmission input shaft and a first and a second gear stage. The transmission input shaft is connected to the electric machine. The drive train has a differential, which is connected to an output of the transmission and is set up to distribute motive power to two drive shafts. The differential is connected to a helically toothed driving gear, which is in engagement with a helically toothed pinion of the transmission output. A pressure pad arrangement absorbs axial forces arising from the helical toothing.
