Four speed transaxle with mid-position transfer drive

摘要

A transaxle for use in a vehicle having an engine mounted transversely with respect to the center plane of the vehicle comprising a compound planetary gear assembly mounted on the axis of the crankshaft for the engine, clutch and brake structure arranged in a strategic fashion to provide a minimum axial dimension for the transaxle, a final drive gear and differential mechanism mounted for rotation about an axis laterally spaced from and parallel to the engine axis, and a chain drive mechanism disposed intermediate the planetary gear assembly and the engine for effecting a driving connection between the driveshaft and the output gear element of the gear assembly whereby the outside dimensions of the transaxle permit packaging of the transaxle in an engine compartment with the engine axis disposed transversely and the driveshafts for the vehicle traction wheels may be positioned to effect a minimum angular displacement with respect to the axis of the differential.
