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.

A die-cast transmission extension housing has an outer peripheral wall or whell and an integral bearing supporting partition wall provided transversely of the longitudinal axis of the shell between the open forward end and the closed rear end thereof. The partition wall supports at least a bearing for the transmission output shaft extending through the open forward end, the bearing on the partition wall and the closed end. The inner surfaces of the shell forwardly of the rear surface of the partition diverge to the open end of the shell so that the inner space defined by these inner surfaces and the partition can be moulded by a die-casting mould part which is slidable out of the inner space through the open end of the shell after the extension housing is die-cast. The upper wall of the extension housing is formed therein with an upper opening adapted to be closed by a shift lever retainer. The side and bottom walls of the shell cooperate with the partition wall to define a second inner space which is so shaped as to be moulded by another diecasting mould part which is slidable out of the second inner space through the upper opening after the extension housing is die-cast.

A power transfer device for four-wheel drive includes a center differential of the bevel gear type (20a) arranged to split the driving power from a power transmission into two torque delivery paths respectively for front-wheel drive and rear-wheel drive, a front-drive differential of the bevel gear type (20b) arranged coaxially with the center differential at one side thereof to transfer the split driving power from a side gear (24) of the center differential to front-wheel axles (15a, 15b), and an output gear (32) for rear-wheel drive arranged coaxially with the center differential (20a) at the other side thereof to transfer the split driving power from another side gear (23) of the center differential to rear-wheel axles (not shown). In the power transfer device, a limited-slip differential (30b) in the form of a viscous coupling is assembled within a mounting case (31) for the output gear (32) to effect limited-slip torque proportional to the difference in rotational speed between the side gears (23, 24).

The present invention relates to a transaxle mechanism for use in a four-wheel drive system of an automotive vehicle. The four-wheel vehicle drive system includes a central differential gear assembly (60), a viscous coupling (100), a front-wheel differential gear assembly (40), a ring gear (81) and a bevel gear (511). The ring gear (81) is fixed to the hub case (693) and the ring gear (81) engages with the bevel gear (511) which is connected to a propeller shaft (514). Located inside the hub case (693) is a viscous coupling limiting differential (100) which controls the difference in rotational speed between the front shafts (42) and the rear shafts (73)
