Actuator for intermittent force transmission device e.g. for automobile differential, has driven rotary plate and cam mechanism for engagement and disengagement movable plate relative to stationary plate

摘要

The actuator has a stationary first plate (15), a relatively displaced second plate (19) engaged with the first plate and a third plate (17) rotated into engagement with the second plate via a drive device, e.g. an electric motor (27) and a cam mechanism converting the rotation of the third plate into an engagement and separation movement, a holder limiting the rotation of the third plate relative to the drive. An Independent claim for an intermittent force transmission device is also included.
