Abstract

Official abstract text for this publication.

A hybrid drivetrain for a motor vehicle includes an automated mechanical transmission (AMT) having an output shaft. The drivetrain includes an alternative energy source including a motor and an energy storage unit and two torque transfer arrangements. The first transfer arrangement is separate from engageable gear sets of the AMT for transferring torque from the output shaft to a motor when the energy storage unit is being charged and for transferring torque from the motor to the output shaft when the energy storage unit is being discharged. Additionally, an alternative energy source clutch for selectively coupling the first torque transfer arrangement to the output shaft is included. The second torque transfer arrangement is for transferring torque from the output shaft to a driven axle of the motor vehicle. At least one of the first and second torque transfer arrangements has different first and second torque transfer ratios.

First claim

Opening claim text (preview).

What is claimed is: 1. A hybrid drivetrain for a motor vehicle, the hybrid drivetrain comprising: an automated mechanical transmission having an input shaft, an output shaft, and a counter shaft, the automated mechanical transmission also including a first gear disposed between the input shaft and the countershaft and at least two selectively engageable gear sets disposed between the countershaft and the output shaft; a master clutch for selectively coupling the input shaft of t…
