A low mass, two piece planetary gear carrier having an integrated clutch housing comprises a first carrier flange and clutch housing and a second carrier flange which are secured together by a plurality of threaded fasteners extending through hollow dowels. A plurality of planet gears receive needle bearing assemblies which are, in turn, supported on pins or stub shafts. The stub shafts are retained in the carrier by transverse retaining pins received in the second carrier flange and extending into the shafts. Unitized washers are disposed between both faces of the planet gears and the flanges. The method of assembly is also a feature of the present invention.

Low mass planetary carrier and clutch housing

A motor vehicle power transfer unit for distributing torque from a transmission assembly between a front wheel drive line and rear wheel drive line. The power transfer unit includes a housing that encloses a parallel gear set and a non-parallel gear set, which are coupled between an input portion and an output portion of the power transfer unit. The parallel gear set includes a driving gear, and idler gear and a driven gear and the idler gear is rotatably supported on a non-rotating support member that extends through the idler gear. Constructed in this manner, reduced lateral compactness of the power transfer unit is achieved.
