Abstract
An acceleration sensitive double overrunning clutch is directionally preset by a change in speed, i.e., acceleration, rather than relative rotation. The clutch is especially adapted for use in power transmission devices such as motor vehicle transfer cases. The clutch includes a plurality of rollers disposed in a like plurality of spaces having symmetrically arranged oblique walls formed by adjacent portions of an inner member and a concentric outer member. The rollers are arranged within a spacing cage which is coupled to an annular weight. A speed change, i.e., acceleration or deceleration, shifts the weight and presets the cage and rollers to function in their engaged or overrunning modes in one direction or the other depending upon the direction of such acceleration.
