A torque transfer assembly includes first and second torque transfer devices (110,210) positioned between a first member (26) and a second member (36).Each of the devices includes a first race (114,214) selectively engageable with the first member, and a second race (122,222) coaxial with the first race. The second race of the first device is coupled to the first race of the second device, and the second race of the second device is coupled to the second member. Each of the devices also includes axially-extending pockets, defined between the first and second races, rollers (118,218) positioned in the respective pockets, and an axial gap formed in one of the first and second races. A force applied to the first race of the first device indexes the first race of the first device relative to the second race of the first device to radially expand the first device to frictionally engage the first member. |
