Abstract: The disclosure relates to a belt pulley decoupler for a motor vehicle drive train that includes a hub constituent part configured for attachment to a crankshaft of an internal combustion engine, a flexible drive element pulley supported in a spring-damped manner relative to the hub constituent part, and a vibration absorber. The vibration absorber includes a mounting plate that extends from a fastening region, which is supported on the hub constituent part and connected to the hub constituent part in a positively locking and/or non-positive manner, radially outwards to a collar region which receives at least one mass element. The fastening region has a plate portion which is supported axially on a flange element of the hub constituent part and which is held relative to the hub constituent part via an axially running dome portion formed either by the mounting plate or the flange element.

Abstract: A drive wheel, comprising a drive disk, which has a traction-means connection region; and a shaft connection region, which can be rotated relative to the traction-means connection region against damping action of a torsional vibration damping device having a spring accommodation chamber. The spring accommodation chamber is filled with lubrication medium and is closed via a cover. The cover has a groove facing the drive disk and containing a sealing means.

Abstract: A pulley decoupler for an accessory drive comprises input and output parts. The output part and the input part are rotatable about a common axis of rotation and are rotatable to a limited extent relative to one another. A centrifugal pendulum device is provided for damping torsional vibrations with a centrifugal pendulum flange that can be rotated about the axis of rotation and has at least one pendulum mass displaceable under centrifugal force relative to the centrifugal pendulum flange. The at least one pendulum mass is acted on by a friction force generated by a first friction device having a first spring and at least one first friction element.

Abstract: A belt pulley decoupler for a motor vehicle drive train, having a hub, a traction pulley having a traction-means receiving contour and being accommodated to rotate about an axis of rotation relative to the hub. The decoupler may include a plurality of bow springs supporting the traction pulley relative to the hub in a direction of rotation, at least one first bow spring being arranged offset in an axial direction and/or a radial direction of the axis of rotation to a second bow spring acting parallel to the first bow spring, and a vibration damping device conjointly connected by means of a carrier to the hub and accommodated on a sleeve-like receiving region of the carrier. The receiving region of the carrier projecting in the axial direction, at least partially, beyond the torque transfer region of the traction pulley.

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 pulley decoupler for an auxiliary unit drive, comprising: an input part comprising a hub; an output part comprising a pulley, wherein the output part and the input part are rotatable about a common axis of rotation; and a flange which is connected to the hub or the pulley by press-fit teeth. An auxiliary unit drive and a drive motor having a corresponding pulley decoupler are provided.

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.
