ABSTRACT:
A clutch assembly for automotive vehicle four-wheel drives either in association with an axle disconnect or wheel hub incorporates a power shift mechanism which can be remotely activated either when the vehicle is static, in motion and during either forward or reverse direction of movement to positively drive the clutch members into and out of engagement with one another. The power shift mechanism includes sealed envelopes in the form of expandable and contractable compartments which in response to a remote control valve will positively shift the clutch members into and out of engagement, and the members will remain in the shifted position without the continued application of force until positively shifted away from that position by the power shift mechanism. In the alternative, a spool-like shifter may be utilized with positive locking elements which will lock the clutch members in the engaged and disengaged position at the end of travel of the shift mechanism. 2
