INLINE ELECTROMECHANICAL VARIABLE TRANSMISSION SYSTEM

Abstract:

A drive system for a vehicle includes first and second gear sets, a connecting shaft and a first electrical machine coupled to the first gear set, a second electrical machine coupled to the second gear set, an output shaft that transports power from the first electrical machine and the second electrical machine to a tractive element of the vehicle, a first clutch selectively rotationally coupling the first gear set to the output shaft when engaged, and a second clutch selectively rotationally coupling the first gear set to the output shaft when engaged. A carrier of the first gear set is selectively coupled to a carrier of the second gear set. The output shaft is aligned with the connecting shaft, the first electrical machine, and the second electrical machine. The first and second clutches are engaged when the drive system is reconfigured into forward and reverse modes of operation, respectively.
