Torsional vibration damper with a couplable damper system, as well as a drive train with torsional vibration damper

摘要

The invention relates to a torsional vibration damper (1) for damping rotational irregularities in a shaft (2) that can be driven by an internal combustion engine, with a damping device (3) which, in the torque flow from the shaft (2) to an output shaft (4), has a primary side (5th ) and a secondary side (6) provided for transmitting the torque to the output shaft (4), and an absorber system (8) which can be coupled to the damping device (3) via a clutch arrangement (7), the clutch arrangement (7) being in a first switching position produces an at least partial operative connection between the absorber system (8) and the damping device (3) and releases this operative connection in a second switch position, the absorber system (8) being supported on the secondary side (6) of the damping device (3), and a drive train (11) For an internal combustion engine-powered automobile, to supply torque from a drive source connected crankshaft (2) to an output shaft (13), with a torque flow between the crankshaft (2) and the output shaft (13) arranged, torsional vibration damper according to the invention.
