TORQUE TRANSFER DEVICE HAVING REDUCED TORQUE VARIATION |
摘要 |
An electrically actuated torque transfer device including an input shaft and at least one output shaft selectively coupled to the input shaft. At least one modulating clutch assembly selectively couples the input shaft to the output shaft. The modulating clutch assembly includes an electrical clutch operator configured to engage a ball ramp operator. The ball ramp operator includes first and second opposed annular rings having complimentarily configured opposed ramped recesses and rolling members disposed in the recesses. Relative rotation of the annular rings translates the annular rings axially to engage the clutch assembly and transfer torque from the input shaft to the output shaft. The first annular ring is coupled to the input shaft and the second annular ring is coupled to the output shaft. A third element disposed between the first annular ring and a shoulder of the input shaft has an engagement diameter selected to minimize torque variations between the torque transfer devices.
