摘要： 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.
