Abstract: A rotor of an electric rotation machine includes a shaft, a laminated core arranged coaxially on the shaft and configured to receive magnets or an electrical conductor, and a torque transmission element non-rotatably connected to a shank of the shaft. The laminated core includes a rotor end plate on an axial side thereof. The torque transmission element has a higher strength than the rotor end plate. The rotor end plate is connected to the torque transmission element via a pin extending into a through-hole and forming a frictional connection with a wall of the through-hole. One of the rotor end plate and the torque transmission element includes the pin, and the other of the rotor end plate and the transmission element includes the through-hole. The pin is formed via pressing into material of the one of the rotor end plate and the torque transmission element.

Abstract: A pulley decoupler for a drive train of a motor vehicle is disclosed for eliminating or reducing rotation-related irregularities transmitted by a crankshaft. The pulley decoupler comprises a pulley hub, an arc spring flange, and a torsional vibration damper flange of a torsional vibration damper. In embodiments, the pulley hub, the arc spring flange, and the torsional vibration damper flange are configured to be non-rotatably mounted on a crankshaft by at least one crankshaft screw. The pulley hub has an outer lateral surface region on which both the torsional vibration damper flange and the arc spring flange are received and on which they are configured to be non-rotatably mounted.

Abstract: A combustion engine component comprises an assembly of a belt pulley for driving auxiliary engine equipment and a torsional vibration damper. The assembly is adapted to be fixed on an engine crankshaft, wherein the belt pulley is of a so called decoupling type, arranged to be able to change its rotational angle relative to the crankshaft and the torsional vibration damper. The torsional vibration damper is partially positioned in a corresponding annular recess in the belt pulley, creating an annular cavity in the recess between the torsional vibration damper and the belt pulley. An annular seal ring is positioned in the annular cavity and is arranged to close off at least a part of the annular cavity from the air surrounding the assembly.
