Abstract
A number of variations may include a torsional vibration damper having an input side, having an output side and having an energy store for the rotationally elastic coupling of the input and output sides in a circumferential direction, wherein, on the input or output side, there is arranged a mass part that is rotatable relative to the input or output side counter to the restoring force of a restoring apparatus.

A torsional vibration damper having an input side, having an output side and having an energy store for a rotationally elastic coupling of the input and output sides in a circumferential direction, wherein, on the input or output side, there is arranged a mass part that is rotatable relative to the input or output side counter to a restoring force of a restoring apparatus, wherein the restoring apparatus has at least one pivotable lever element providing an actuating force to be transmitted to the mass part so as to generate the restoring force acting on the mass part, the lever element being pivotable about an articulation point which is adjustable or displaceable with variation of a lever ratio of the lever element, wherein the energy store has multiple support shoes or connecting shoes which are rotatable relative to the input or output side and which serve for the support and connection of one or more spring elements of the energy store.
A torsional vibration damper having an input side, having an output side and having an energy store for a rotationally elastic coupling of the input and output sides in a circumferential direction, wherein, on the input side or the output side, there is arranged a mass part that is rotatable relative to the input or output side counter to a restoring force of a restoring apparatus, wherein the restoring apparatus has at least one pivotable lever element providing an actuating force to be transmitted to the mass part so as to generate the restoring force acting on the mass part, the lever element being pivotable about an articulation point which is adjustable or displaceable with variation of a lever ratio of the lever element, and wherein the restoring apparatus has a spring device for generating the actuating force, the spring device having a first spring element and a second spring element which act on the lever element oppositely to one another and which are in the form of helical compression springs, wherein the first spring element and the second spring element extend along a common longitudinal axis.
A torsional vibration damper having an input side, having an output side and having an energy store for a rotationally elastic coupling of the input and output sides in a circumferential direction, wherein, on the input or output side, there is arranged a mass part that is rotatable relative to the input or output side counter to a restoring force of a restoring apparatus, wherein the restoring apparatus has at least one pivotable lever element providing an actuating force to be transmitted to the mass part so as to generate the restoring force acting on the mass part, the lever element being pivotable about an articulation point which is adjustable or displaceable with variation of a lever ratio of the lever element;
- and
- wherein at least one support part is provided which is connected rotationally conjointly to the mass part and which, supporting the mass part at an inside in a radial direction, is supported in a region of a diameter which is smaller than a greatest outer diameter of that side of the input or output side which faces outward toward the mass part in the radial direction, which support part is supported at the inside in the radial direction in a region of the same diameter as the input or output side, the support part being of disk-shaped form, at least partially having a smaller extent in an axial direction than the mass part, and being arranged between two disks of the input or output side as viewed in the axial direction.
