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 firstand second electronically-switched magnetic fields, respectively. A translator structure includes first and second cams having contour surfaces and a magnetically-latching, permanent magnetic sourcemagnetically 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 62 / 513,567, filed June 1, 2017. technical field [0003] The present invention relates generally to overrunning, non-friction radial linkage and control assemblies and switchable linear actuation devices for such assemblies. Background technique [0004] A typical one-way clutch (OWC) includes an inner ring, an outer ring and a locking device between the two rings. One-way clutches are designed to lock in one direction and allow free rotation in the other. The two types of one-way clutches commonly used in automatic transmissions for vehicles include: [0005] - the roller type, which includes spring-loaded rollers between the inner and outer races of the one-way clutch (in some applications the roller type is also used without springs); and [0006] - The sprag type comprising an asymmetrically shaped wedge between the inner and outer races o...
