Hybrid automated manual transmission
View Patent ↗A hybrid automated manual transmission includes 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 is concentric with the input shaft and includes at least two main shaft gears connectable to the main shaft. At least one countershaft includes 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. A motor generator is drivingly connected to the input shaft.
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 concentric with the input shaft and drivingly connected to the input shaft by a planetary gear system, wherein the planetary gear system includes a planetary carrier fixed to the input shaft.
2. The hybrid automated manual transmission according to claim 1 , further comprising a range gear system drivingly connected to the main shaft.
3. The hybrid automated manual transmission according to claim 2 , further comprising a retarder drivingly engaged with an output shaft of the range gear system.
4. The hybrid automated manual transmission according to claim 1 , wherein the planetary gear system includes a sun gear connected to the motor generator.
