Title: OVERRUNNING, NON-FRICTION, RADIAL COUPLING AND CONTROL ASSEMBLY AND SWITCHABLE LINEAR ACTUATOR DEVICE FOR USE IN THE ASSEMBLY
Abstract:
A switchable linear actuator device and an overrunning, non-friction, radial coupling and control assembly using the device are provided. The device has magnetic sources which produce corresponding magnetic fields to create net translational forces. The device includes a first and locking members and a stator structure including a first and second electromagnetic sources configured to create first and second electronically-switched magnetic fields, respectively. A translator structure includes first and second cams having contour surfaces and a magnetically-latching, permanent magnetic source magnetically coupled to the stator structure across a radial air gap. The translator structure translates along an axis between first and second axial positions and between second and third axial positions upon experiencing first and second net translational forces, respectively, to cause the first and second locking members to ride on the contour surfaces of the first and second cams, respectively, and perform a sequenced shift.
