Abstract
A motor vehicle transmission, shiftable between different transmission ratios, with an input shaft, an output shaft, and in some cases a countershaft has a plurality of gears arranged to cooperate in gear pairs, a plurality of clutches, and an electro-mechanical energy converter. The electro-mechanical energy converter can be coupled to the transmission through at least one of the clutches in order to perform at least one of the functions of starting the combustion engine of the vehicle, temporarily replacing or assisting the combustion engine in propelling the vehicle, maintaining vehicle traction during gear shifts, generating electrical energy from kinetic energy, and storing said electrical energy in a storage device.
Claims38
A transmission comprising at least two shafts, one of the shafts being an input shaft and another of the shafts being an output shaft, a plurality of gears arranged to cooperate in gear pairs, a plurality of clutches, and an electro-mechanical energy converter with at least a rotor and a stator, wherein the transmission is shiftable between a plurality of different transmission ratios and is adapted to transmit a torque between the input shaft and the output shaft, the input shaft being adapted so that it can be driven by an engine torque of a crankshaft of a combustion engine of a vehicle, and at least one of the clutches is adapted to engage and disengage a first connection between the rotor and at least one of the input shaft and the output shaft, wherein the at least one of the clutches is adapted to alternatively switch said first connection so that the input shaft is engaged while the output shaft is disengaged and vice versa.
