  • Limiting torque clutch in an input damper
    Patent number: 9435390
    Abstract: The present disclosure provides an input damper for coupling to a torque-generating mechanism. The damper includes an outer cover, a hub, and a carrier assembly coupled to the hub. The carrier assembly is movably disposed within the cover. A clutch assembly moves between an engaged position and a disengaged position. The input damper further includes an angular displacement mechanism operably coupled to the clutch assembly for moving the clutch assembly between the engaged position and disengaged position. A damper spring is disposed between the outer cover and the clutch assembly. The outer cover is coupled to the carrier assembly in the engaged position.

  • Limiting torque clutch in an input damper
    Patent number: 8939843
    Abstract: The present disclosure provides an input damper for coupling to a torque-generating mechanism. The damper includes an outer cover, a hub, and a carrier assembly coupled to the hub. The carrier assembly is movably disposed within the cover. A clutch assembly moves between an engaged position and a disengaged position and is biased towards the engaged position. The input damper further includes an angular displacement mechanism operably coupled to the clutch assembly for moving the clutch assembly between the engaged position and disengaged position. The outer cover is coupled to the carrier assembly in the engaged position.
