Abstract: A hybrid shaft is provided, particularly a hybrid shaft for a vehicle, for transmitting a torque. The hybrid shaft includes a hollow shaft made of metal, wherein the hollow shaft has at least one reinforcement layer made of fiber-reinforced plastic on an outer surface of the hollow shaft in at least one reinforcement section. The hollow shaft has an external diameter varying in a longitudinal direction of the hollow shaft inside the at least one reinforcement section.

Abstract: A rotor element or a star disk which is designed to be arranged on an electrically excited rotor of an electric machine, includes a base which is designed to be arranged in an insert between the axial end of a laminate stack of the rotor and at least one end winding of the rotor. At least one fin is fastened on the base and is designed to protrude in the insert through the at least one end winding axially out of the at least one end winding.

Abstract: A torque transmission device, includes an outer tube and an inner tube, which is inserted a certain distance into the outer tube. The outer tube is joined to the inner tube exclusively by way of a bonded joint in the torque transmission direction and in the longitudinal direction of the outer tube.

Abstract: A plate clutch for motor vehicles especially motorcycles, which are arranged to ensure its pressure plate is centered, to ensure that a release force is concentrically applied, and to permit use of a spring type which reduces clutch release force and thereby improves operator comfort. The plate clutch includes a primary gear driven by an engine and rotatably mounted on a clutch shaft, a clutch cage connected to the primary gear and corresponding driver connected to the clutch shaft, a pressure plate splined to the driver, a pressure pad rigidly connected to the pressure plate, a belleville spring supported on the driver and on the pressure pad, annular clutch plates, stacked between the pressure plate and the driver, a throwout bearing which transfers an axial release force to the pressure plate, and a pressure mushroom inserted into the internal ring of the throwout bearing and lying against it with an annular flange.
