Abstract

A start-up element comprises a torsional vibration damper (2) which can be coupled to a drive (16), said damper having a drive-side input element (37), which can be rotated against an effect of a first spring element arrangement (40a) around an axis of rotation (10) in respect of an intermediate transfer (48, 49), and having an output-side output component (42) which can be rotated against the effect of a second spring element arrangement (40b) around the axis of rotation (10) in respect of the intermediate transfer (48, 49) which output element is coupled to an output (8) of the start-up element in a rotationally fixed manner. A hydrodynamic coupling device (4) has a turbine wheel (22) and a turbine wheel flange (26) connected for conjoint rotation therewith, wherein the turbine wheel flange (26) is coupled to the output (8) in a rotationally fixed manner by means of a first mechanical connection (32). A vibration damper (6) has an absorber carrying element (46a) carrying at least one absorber weight (47), which absorber carrying element is coupled in a rotationally fixed manner to the intermediate transfer (48, 49) by means of a second mechanical connection (44), wherein said absorber carrying element (46a) extends opposite a radial direction (28) standing perpendicular to the rotational axis (10) as far as a component of the output (8).

Description

technical field [0001] Embodiments of the invention relate to a starting element, in particular a starting element with a hydraulic coupling element comprising a torsional vibration damper and a vibration damper. Background technique [0002] Starting elements for transmitting torque from a drive unit to a downstream drive train, such as a transmission, are known in various embodiments. For automatic starting, fluid coupling elements are often used, ie hydrodynamic circuits without torque conversion (hydrodynamic clutches) or hydrodynamic circuits with torque conversion (torque converters). In order to increase the energy efficiency after starting, it is mechanically closed by the converter lock-up clutch in the so-called closing operation in order to prevent flow losses and optimize the consumption of fuel or drive energy. [0003] Such a starting element or starting converter is often combined with a torsional vibration damper, which can be designed as a single-stage or m...
