Abstract
A system includes a planetary gear assembly having a ring gear, a plurality of planet gears coupled to a carrier, and a sun gear coupled to a main shaft. The system further includes a driven gear coupled to the carrier, a countershaft gear coupled to the driven gear, a motor/generator coupled to the main shaft, and an actuator structured to change a coupling of the ring gear based on a position of the actuator.
Claims26
A system, comprising:
- a planetary gear assembly having a ring gear, a plurality of planet gears coupled to a carrier, and a sun gear coupled to a main shaft;
- a driven gear coupled to the carrier;
- a countershaft gear coupled to the driven gear;
- a motor/generator coupled to the main shaft;
- a clutch to selectively decouple the motor/generator from the main shaft;
- and
- an actuator structured to change a coupling of the ring gear based on a position of the actuator,
- wherein the actuator is further structured to, at a first position, couple the ring gear to a housing to stop a rotation of the ring gear with respect to the main shaft,
- wherein the actuator is further structured to, at a second position, couple the ring gear to the carrier, and
- wherein the clutch is configured to couple the motor/generator to the main shaft when the actuator is in the first position or the second position.
