  • Rotary power transmission device with bi-stable clutch
    Patent number: 11920666
    Abstract: A power transmission device includes a clutch, an actuator and a stop member. The clutch is received within a first housing and has a first clutch member coupled to the second housing and a second clutch member coupled to the first housing, the second clutch member is movable and selectively engageable with the first clutch member. The actuator has a coil and a plunger driven for movement by a magnetic field generated by the coil so that the plunger moves axially to move the second clutch member relative to the first clutch member. The stop member has a retracted position spaced from the plunger and an advanced position within a path of movement of the plunger to limit movement of the plunger when the stop member is in the advanced position.
