An output member is operatively connected to rotate in unison with the countershaft. Multiple pairs of intermeshing gears are included, each having a respective synchronizable gear that rotates about one of the input shaft and the countershaft, and a respective fixed gear mounted to the other one of the input shaft and the countershaft to rotate in unison therewith. An electric motor has a rotor concentric with and rotatable about the first axis of rotation. A first synchronizer is selectively engageable to synchronize rotation of the rotor with the input shaft. A second synchronizer is selectively engageable to synchronize rotation of the rotor with one of the synchronizable gears that rotates about the input shaft.

Abstract: An automated electric manual transmission (EMT) has an input member, an output member, and at least one shaft. The input member and the at least one shaft are rotatable about a first axis of rotation. A countershaft is substantially parallel with the at least one shaft and is rotatable about a second axis of rotation. The output member is operatively connected to rotate with the countershaft. A transmission controller controls engagement of a plurality of torque-transmitting mechanisms to selectively establish different gear ratios from the at least one shaft to the transfer shaft through pairs of intermeshing gears. An electric motor and a planetary gear set are concentric with the first axis of rotation. The electric motor can provide torque to a member of the planetary gear set.
