Output shaft assembly in power transfer device.

摘要

In combination with a power transmission (20) for an automotive vehicle, a power transfer device includes a transfer casing (12) secured at one side thereof to a casing (11) of the power transmission, a ring gear (41) rotatably mounted within the transfer casing to be applied with driving power from the power transmission (20) through a center differential (30a) , and an output shaft assembly (40a) mounted within the transfer casing to transmit the driving power from the ring gear to a propeller shaft. The output shaft assembly (40a) includes a drive pinion (42) integrally formed with an internally splined hollow shaft portion (42b) rotatably mounted within the transfer casing and being in mesh with the ring gear (41), and an externally splined slide shaft (43) axially slidably coupled within the hollow shaft portion (42b) of the drive pinion for rotation therewith and having an output end portion for drive connection to the propeller shaft.
