GENISE THOMAS A / DOROBANTU MIHAI

The present application relates to a drivetrain for a motor vehicle comprising an automated mechanical transmission (12) having an input shaft (28), an output shaft (30), a counter shaft (32) and at least two selectively engageable gear sets disposed between the countershaft and the output shaft. In order to assist in launching the vehicle, the application provides an alternative power source including a motor (50) and an energy storage unit (52, 54) and an adapter module (20) operable disposed between the automated mechanical transmission (12) and the motor (50). Said module (20) comprises an adapter gear set including a first gear (42) in mesh with a second gear (44), providing driving connections between the motor (50) and the transmission output shaft (30), a first clutch (46) selectively drivingly connecting the motor input shaft (38) to the countershaft (32) and a second clutch (44) selectively connecting the transmission output shaft (30) to the motor input shaft (38) through the adapter gear set (42, 44). The motor (50) may be hydraulic or electric.
