Abstract:
A shaft coupling comprising:a first attachment element and a second attachment element that are rotatable relative to one another and that are connected to one another by a rotationally resilient assembly. and a dampening device that is active between said first and said second attachment elements for the purpose of suppressing torsional vibration of said rotationally resilient assembly; said rotationally resilient assembly comprising a first ramp disc and a second ramp disc (18, 20, 118, 120) that are rotatable relative to one another and that support one another at least indirectly; one of said first and said second ramp discs supported in a rotationally fixed and rigid manner on one of said first and said second attachment elements and the other of said first and said second discs supported in a rotationally fixed and axially resilient manner on the other of said first and said second attachment elements by a spring (28, 128); and said dampening device comprising a viscous coupling having a hub (31, 131) connected to one of said first and said second attachment elements and a housing (34, 134) connected to the other of said first and said second attachment elements.
