DRIVE TRAIN FOR A VEHICLE AND ELECTROMECHANICAL DEVICE COUPLED TO A POWER MACHINE

摘要

A powertrain and an electromechanical device are disclosed. A ring gear is attached to a first distal end of a crankshaft so that the ring gear and the crankshaft are rotatable in unison about a longitudinal axis. A motor generator includes a motor / generator shaft that is rotatable about a first axis spaced from the longitudinal axis. A starter mechanism includes a first starter gear that is coupleable to the motor / generator shaft and rotatable about a second axis spaced from the longitudinal axis. The first starter gear is along the second axis between a first position in which it is engaged with the ring gear, so that torque from the motor / generator shaft through the first starter gear and the ring gear is transmitted to the crankshaft to the engine to Start, and a second position movable in which it is disengaged from the ring gear to rotatably separate the starter mechanism of the ring gear.
