SYSTEM FOR TRANSMITTING TORQUE WITH SPEED MODULATION

摘要

A system (104) is provided for transmitting torque with speed modulation between a motor generator (101) and an engine (102). The system (104) includes a first shaft (106), a second shaft (108), a first reduction gearset (110), and a second reduction gearset (124). The first shaft (106) is configured to rotatably connect with the motor generator (101). The second shaft (108) is configured to rotatably connect with the engine (102). The first reduction gearset (110) is rotatably supported at least in part on the first shaft (106). The first reduction gearset (110) is disposed in selective engagement with the first shaft (106) via a first overrunning clutch (112) disposed therebetween. The second reduction gearset (124) is rotatably supported at least in part on the first shaft (106) and at least in part on the second shaft (108). The second reduction gearset (124) is disposed in selective engagement with the first shaft (106) via a second overrunning clutch (126) disposed therebetween.
