Abstract
Coupling mechanisms for torque transmitting shafts are provided with sliding and fixed plates operably connectable to respective torque transmitting shafts, and a leaf spring having a preloaded spring force exerted on the sliding plate when the sliding and fixed plates are operably connected to one another. A hub is attached to the leaf spring and coaxially received within the sliding plate to allow the sliding plate to be capable of reciprocal axial movements relative to the hub between engaged and disengaged positions wherein the sliding and fixed plates are engaged and disengaged with one another so as to allow and prevent torque being transmitted from one to another of the shafts, respectively. An inner piston is coaxially received within the hub and moveable between a first position wherein the hub retains the sliding plate in the engaged position thereof, and a second position wherein the hub releases the sliding plate to allow movement of the sliding plate under bias force from the leaf spring into the disengaged position thereof.
