Patent number: 11773913Abstract: A torque-transmitting clutch includes a first clutch element having a first base body and a first end face, a second clutch element, and a third clutch element having a third base body. In a closed position, the first and the second clutch elements are connectable in a positive locking and/or force-fit manner for transmitting torque, and in an open position, this positive locking and/or force-fit connection is released, and wherein the first clutch element is connectable to the third clutch element in a positive locking and/or force-fit manner. The first clutch element is produced according to a powder-metallurgical or an additive method and has at least one centering projection arranged on the first end face and extending towards the third clutch element to cooperate with and/or be accommodated with a centering recess in an end face in the third clutch element in a positive locking and/or force-fit manner.Type: GrantFiled: December 7, 2022Date of Patent: October 3, 2023Assignee: MIBA SINTER AUSTRIA GMBHInventor: Christian Kronberger
