Zusammenfassung: | A four wheel drive transfer case having a three element planetary gear differential connected to the output shaft of a transmission and having two output shafts 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 predetemined timed relationship. The transfer case further includes an electromagnetically actuated friction clutch assembly including a ball ramp mechanism and having frictionally engageable members for operably interconnecting two of the planetary gear components in a manner such that relative rotation between the two output shafts is modulated by a torque level established between the frictionally engageable members of the clutch. |
