摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
