Power train for a motor vehicle
First Claim
1. A power train for a motor vehicle, said power train comprising a combustion engine with a driving shaft turning at a first rpm rate, at least one torque-coupling device, a transmission with a transmission input shaft, and at least one electro-mechanical energy converter with an energy-converter shaft turning at a second rpm rate, said electro-mechanical energy converter being operable at least as a motor and as a generator and having an interactive rotary connection to the driving shaft;
- wherein the interactive rotary connection has at least two rpm ratios defined as quotients of the first rpm rate divided by the second rpm rate, and wherein the at least two rpm ratios automatically set themselves according to which of at least two operating modes the electro-mechanical energy converter is working in, said at least two operating modes comprising a start-up mode and a driving mode.

Abstract
A power train for a motor vehicle includes a combustion engine, a clutch or other torque-coupling device, a transmission, and an electro-mechanical energy converter that is operable at least as a motor and as a generator. The electro-mechanical energy converter is coupled to the output shaft of the combustion engine through a torque transfer device with at least two rpm ratios that automatically set themselves according to whether the vehicle is operating in a start-up mode or in a driving mode.
