1. A powertrain for a vehicle, the powertrain comprising:
an engine including a housing and a crankshaft at least partially disposed inside the housing, with the crankshaft being rotatable about a longitudinal axis; a ring gear attached to a first distal end of the crankshaft such that the ring gear and the crankshaft are rotatable in unison about the longitudinal axis; a motor-generator including a motor/generator shaft being rotatable about a first axis, with the first axis being spaced from the longitudinal axis; and a starter mechanism including a first starter gear coupleable to the motor/generator shaft, wherein the first starter gear is rotatable about a second axis, with the second axis being spaced from the longitudinal axis, and the first and second axes being spaced from and substantially parallel to each other, and with the first starter gear being movable along the second axis between a first position engaging the ring gear such that torque is transferred from the motor/generator shaft through the first starter gear and the ring gear to the crankshaft to start the engine, and a second position disengaged from the ring gear to rotatably disconnect the starter mechanism from the ring gear. |
