Abstract: A driving disc with a hub and a disc rim which are rotatably supported inside one another, with at least two wound wire springs which are mounted substantially coaxially relative to the hub and disc rim and whose one end is secured in the direction of rotation relative to the hub and whose respective other end is secured in the direction or rotation relative to the disc rim.

Abstract: A spring plate for a valve spring of an internal combustion engine, which spring plate can be connected directly to the valve stem of a charge changing valve while engaging an annular groove in the valve stem. An annular disc is arranged on the valve spring and two supporting tongues which are directed radially inwardly from the annular disc and whose inner ends, in a plan view of the spring plate, comprise recesses for engaging an annular groove.

Abstract: A method of producing assembled camshafts from a tubular member and components slid on to same and having through-holes and outer functional faces, wherein the components are provided with through-holes which have been machined by non-chip-forming operations and on which an outer contour is preferably finish-machined; wherein the tubular member can be clamped in so as to be centred on a reference axis B; wherein the components are slid on and are centred via their outer contour on the reference axis of the clamping means of the tubular member; wherein, between the through-holes and the tubular member, a compensating and joining gap is provided and wherein; between the components and the tubular member with material being added, a material locking connection or a press fit connection is provided by expanding the tubular member.

Abstract: An assembled camshaft comprising a tubular shaft and a plurality of components each provided with a through-aperture, more particularly cams which have been slid on to the tubular shaft and are fixed thereon at a distance from one another, wherein, between the components, the tubular shaft comprises inwardly formed side indentations, wherein at least individual indentations extend underneath at least one of the components.

Abstract: A helical compression spring (3) with two end turns (7) and a transition area adjoining each end turn (7) as an axle spring for wheel suspensions of motor vehicles, for example, for wheel suspensions with a wheel-guiding MacPherson strut unit (5) which has a helical compression spring (3) and a shock absorber (4), and which is connected, on the one hand, to the body (1), and on the other hand, to the wheel (2), and with a suspension arm (6). The helical compression spring (3) has its vibration strength and the service life greatly increased by the end turns (7) and/or transition regions being machined by worked hardening by rolling and/or by work hardening by hammering.

Abstract: An assembled camshaft (11) wherein at least one oil distributing sleeve (14, 26) for a camshaft setting device (15) is secured in a force-locking way to a plastically expanded portion of a shaft tube (12), wherein the oil distributing sleeve (14) includes a seat face (31) centered on the axis A of the shaft tube (12) and/or a radial contact face (32) for the camshaft setting device (15), which radial contact face (32) is aligned in a normal way relative to the axis A of the shaft tube (12).

Abstract: A driving disc with a hub and a disc rim which are rotatably supported inside one another, with at least two wound wire springs which are mounted substantially coaxially relative to the hub and disc rim and whose one end is secured in the direction of rotation relative to the hub and whose respective other end is secured in the direction or rotation relative to the disc rim.

Abstract: A spring plate for a valve spring of an internal combustion engine, which spring plate can be connected directly to the valve stem of a charge changing valve while engaging an annular groove in the valve stem.

Abstract: A tensioning device for attraction mechanism including a receiving and mounting housing, a roller carrier pivotably connected to the mounting housing, a bearing which radially supports the roller carrier relative to the mounting housing, a spring between the roller carrier and the mounting housing for applying a tensioning force, and a damping device. The damping device includes a damping bush which, by friction, dampens any movement between the roller carrier and the mounting housing in such a way that damping is greater in the direction of an increasing tension force than in the direction of decreasing tension force. A flat band spring applies the friction force to the damping bush. The flat band spring is secured, at a first end, to the receiving and mounting housing in a rotationally fast way, and at a second end to the damping bush in a rotationally fast way.

Abstract: A method and device for joining assembled hollow shafts which consist of a tube and several attachable parts such as cams, flanges, bearing sleeves, pulse generating devices, toothed gears and chain gears slid on to the tube, wherein the tube, inside the attachable parts, is radially plastically expanded in individual portions by applying internal pressure in such a way that the attachable parts are secured to the tube by a permanent press fit, wherein the attachable parts and the tube are individually positioned and fixed relative to one another and wherein the tube is sequentially plastically expanded in individual portions associated with the individual attachable parts.
