A bidirectional 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 rollers disposed within
recesses of the roller assembly. The roller assembly also includes a
spring extending from the roller assembly to exert frictional forces
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 engagements
between the rollers and the hubs.
