Bi-directional overrunning clutch for a primary drive axle
Abstract:
A bi-directional overrunning clutch for transmitting torque to segments of a primary drive axle. The clutch includes an input gear, a clutch housing, and hubs extending out of the housing that attach to the segments. A roll cage is located within the housing and has rollers arranged in two sets, each set located adjacent to a hub. The rollers wedge between the hubs and first tapered portions on the clutch housing when the roll cage is rotated in a first direction relative to the housing (forward-engagement position), and between the hubs and second tapered portions on the clutch housing when the roll cage is rotated in a second direction relative to the housing. A friction member contacts the roll cage to engage the roll cage to the hub to wedge the rolls between the hubs and the clutch housing.
