Abstract

Claims (21)

1 . A hybrid automated manual transmission, comprising:

an input shaft configured to be connected to a prime mover by an input clutch;

at least one splitter gear connectable to the input shaft;

a main shaft coaxial with the input shaft;

at least two main shaft gears connectable to the main shaft;

at least one countershaft having at least one first driven gear drivingly engaged with the at least one splitter gear and at least two second driven gears drivingly engaged with the at least two main shaft gears; and

a motor generator drivingly connected to the input shaft by a reduced gear ratio, wherein the motor generator is at a rear of the main shaft.

2 . The hybrid automated manual transmission according to claim 1 , wherein the motor generator is drivingly connected to the input shaft by a gear mounted to the input shaft.

3 . The hybrid automated manual transmission according to claim 2 , wherein the motor generator includes a drive shaft and a drive gear that are engaged with the gear mounted to the input shaft.

4 . The hybrid automated manual transmission according to claim 1 , further comprising a range gear system drivingly connected to the main shaft.

5 . The hybrid automated manual transmission according to claim 4 , further comprising a retarder drivingly engaged with an output shaft of the range gear system.

6 . A hybrid automated manual transmission, comprising:

an input shaft configured to be connected to a prime mover by an input clutch;

at least one splitter gear connectable to the input shaft;

a main shaft coaxial with the input shaft;

at least two main shaft gears connectable to the main shaft;

at least one countershaft having at least one first driven gears drivingly engaged with the at least one splitter gear and at least two second driven gears drivingly engaged with the at least two main shaft gears; and

a motor generator drivingly connected to the input shaft by a gear mounted to the input shaft, wherein the motor generator is at a rear of the main shaft.

7 . The hybrid automated manual transmission according to claim 6 , wherein the motor generator includes a drive shaft and a drive gear that are drivingly engaged with the gear mounted to the input shaft.

8 . The hybrid automated manual transmission according to claim 6 , further comprising a range gear system drivingly connected to the main shaft.

9 . The hybrid automated manual transmission according to claim 6 , further comprising a retarder drivingly engaged with an output shaft of the range gear system.
