Abstract:
A shaft coupling comprising:a first attachment element (51, 151) and a second attachment element (52, 152) that are rotatable relative to one another and 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 vibrations of said rotationally resilient assembly;said rotationally resilient assembly comprising a torsion bar (55, 155) having a first end connected to one of said first or said second attachment elements in a rotationally fixed manner and a second end, opposite said first end, connected to the other of said first aid said second attachment elements in a rotationally fixed manner; andsaid dampening device comprising a viscous coupling having a hub (71, 171) connected to one of said first and said second attachment elements in a rotationally fixed manner and a housing (74, 174) connected to the other of said first and said second attachment elements in a rotationally fixed manner, and further comprising a rotary tube spring (183) arranged concentrically relative to said torsion bar, with a first end of said rotary tube spring connected in a rotationally fixed manner to one of said first and said second attachment elements and with a second end of said rotary tube spring opposite said first end being freely rotatable within a limited angle relative to the other of said first and said second attachment elements.
