Zusammenfassung:FOUR WHEEL DRIVE TRANSFER CASE A four wheel drive transfer case (24) having a three element planetary gear differential (38) connected to the output shaft (40) of a transmission and having two output shafts (42,44) which are driven by the differential in a manner such that rotary motion of any one shaft effects rotary motion of the other shafts in a predetermined timed relationship. The transfer case further includes an electromagnetically actuated friction clutch assembly (46) including a ball ramp mechanism and having frictionally engageable members (92,94) for operably interconnecting two of the planetary gear components in a manner such that relative rotation between the two output shafts (44,42) is modulated by a torque level established between the frictionally engageable members of the clutch.
