摘要： A hybrid power train with a low-voltage motor-generator. Such a hybrid power train may include a low-voltage motor-generator arranged in a concentric manner around a drive shaft to form a driving connection between a rotor of the low-voltage motor-generator and the drive shaft; and a hollow shaft between the low-voltage motor-generator and the drive shaft, the hollow shaft comprising an outer spline at a first end portion, connected to the rotor of the low-voltage motor-generator, and an inner spline at a second end portion, connected to the drive shaft, wherein both the connection of the outer spline to the rotor of the low-voltage motor-generator and the connection of the inner spline to the drive shaft is formed as a crowned spline connection to accommodate for horizontal and/or vertical angular misalignment and/or horizontal and/or vertical displacement between the drive shaft and the rotor.
