Patent ID: 8196725

Claim:
A device ( 1 ) for connecting, in a rotationally fixed manner, a shaft ( 2 ) and at least one component ( 3 ) which is rotatably supported on the shaft ( 2 ), the device ( 1 ) comprising: at least one actuating element ( 6 , 15 , 16 ) being supported by the shaft ( 2 ) in a rotationally fixed, but axially slidable manner; the at least one component ( 3 ) being axially slidable along the shaft and having first and second frictional surfaces; an actor ( 5 ), which with an actuating force axially displaces the at least one actuating element ( 6 , 15 , 16 ) such that the at least one actuating element ( 6 , 15 , 16 ) axially biases the at least one component ( 3 ), and the at least one actuating element ( 6 , 15 , 16 ) frictionally engages the first frictional surface of the at least one component ( 3 ) such that the at least one component ( 3 ) and the shaft ( 2 ) rotate at essentially an equal speed; at least one spring device ( 8 A, 8 B) being located radially inward of the frictional engagement between the at least one component ( 3 , 14 ) and the at least one actuating element ( 6 , 15 , 16 ) for separating the at least one component ( 3 , 14 ) from the at least one actuating element ( 6 , 15 , 16 ), and a holding device for retaining the active frictional connection between the at least one actuating element ( 6 , 15 , 16 ) and the at least one component ( 3 ), without the actor ( 5 ) providing a further actuating force, such that the at least one component ( 3 ) is connected, via the at least one actuating element ( 6 , 15 , 16 ), in a rotationally fixed manner with the shaft ( 2 ).
