A bi-directional overrunning clutch comprising an input gear, a pair of
hubs, and a roller assembly is provided. Each hub is engaged to an end of
one of a pair of shaft segments of a primary drive axle. The roller
assembly is disposed within the input gear and about at least a portion
of each hub. The roller assembly includes spring pins, extending from the
roller assembly, with ball locks adapted to engage detents on the surface
of each hub, so as to form spring pin engagements between the roller
assembly and the hubs. In operation, rotation of the input gear causes
rotation of the roller assembly. Thereafter, rotation of the roller
assembly causes rotation of the hubs via the spring pin engagements. The
spring pins, however, are generally adapted to disengage the spring pin
engagements when one of the hubs rotates faster than the other hub.
