Abstract (en)
[origin: WO2019042695A1] The invention relates to a torsional vibration damper (1; 1a; 1b), which is provided with at least one energy storage device (46). Said energy storage device has an input (36), which is connected to a coupling system (18), an output (56; 56a; 56b), which can be rotationally deflected relative to the input against the action of at least one stored energy source (45), and a rotational angle stop (42), which limits the rotational deflection of the output (56; 56a; 56b) relative to the input (36). The torsional vibration damper (1; 1a; 1b) also has a damping system (55, 55b). Said damping system has at least one damper-mass support (49; 49b) for holding at least one damper mass (74; 74b) movable relative to the damper-mass support. The damper-mass support (49; 49b) of the damping system (55, 55b) acts as the output (56; 56a; 56b) of the energy storage device (46). The rotational angle stop (42) is provided at a position of the energy storage device (46) that is located before the at least one stored energy source (45) of said energy storage device (46) in the transmission direction of a torque transmitted by the coupling system (18), such that it is ensured that a torque supplied to the damper-mass support (49; 49b) via the at least one stored energy source (45) is limited to a predefined limit torque by the rotational angle stop (42).
