ABSTRACT:
An impulse actuated clutch with latch for a drive line of a vehicle. The impulse actuated clutch has a coupling member that is permanently engaged with one of a driven member and a driving member. The coupling member is movable in a first direction to engage one of the driven and driving members and is movable in a second direction to engage both the driven and driving members. The coupling member is biased to move in the first direction by a return spring. The coupling member is moved in the second direction by a first pulse of air pressure applied to a piston assembly connected to the coupling member. Formations formed on a primary piston of the piston assembly and the driven member cooperatively latch the piston in the second position to the maintain the coupling member in engagement with both the driven and driving members upon release of the first pulse of air pressure. A second pulse of air pressure greater in magnitude than the first pulse moves the primary piston further in the second direction against a second spring, which unlatches the piston permitting the piston and coupling member to move in the first direction to uncouple the driven member from the driving member.
