Abstract: A ring portion of a torque converter shell having a first segment at a distal end of the ring portion, a second segment at a second end of the ring portion adjacent an annular portion of the shell, and a ribbed portion located axially between the first segment and the second segment, and extending in a radial direction beyond the first and second segments.

Abstract: A damping device for damping speed irregularities of a rotating shaft includes an armature having at least one armature part made of a non-ferromagnetic, electrically conductive material. An exciter configured to permeate the armature part in at least some regions with a magnetic flux. The armature, together with the at least one armature part, is movably supported relative to the exciter, transversely to the direction of the magnetic flux. In one region permeated by the magnetic flux in a position of normal use, the armature part has at least one opening in which a ferromagnetic flux-guide member is located.

Abstract: A method for controlling the adjustment of a continuously variable transmission in which pairs of conical disks are adjustable relative to each other so that transmission ratios can be set continuously between first and second shafts on which the respective conical disk pairs are positioned. In respective absolute end positions of the adjustable disks the transmission ratio assumes an extreme value. A control system provides that in a first adjustment range the adjustable disks are always kept within relative end positions that are at least at a defined distance from the absolute end positions. In a second operating state, the adjustment of the adjustable disks is controlled in such a way that the adjustable disks can be moved within a second adjustment range over the entire adjustment distance to the absolute end positions, so that in the second operating state a maximum possible spread of the transmission is utilized.
