Abstract
In combination with a power transmission, a power transfer device comprises a transfer casing detachably secured to a transmission casing, a first differential rotatable within the transmission casing and having a first gear casing driven by an output gear of the transmission, a second differential coaxial with the first differential having a second gear casing integral with an output element of the first differential and rotatable within the first gear casing, a carrier member rotatably mounted within the transfer casing and arranged coaxially with the first and second differentials, a first axle connected with an output element of the second differential and extending outwardly from the transmission casing, a second axle connected with another output element of the second differential and extending outwardly from the transfer casing through the carrier member, a hollow shaft in surrounding relationship with the second axle and connected at its opposite ends with another output element of the first differential and the carrier member, and a clutch sleeve slidably mounted on the hollow shaft to be engaged with the first gear casing. The clutch sleeve is arranged to be axially slida…
