Abstract
A flywheel, including a first rotating ring that is connectible to a drive shaft and a second rotating ring that is connectible to a driven shaft. The first and the second rotating rings are twistable relative to one another and are supported concentrically one inside the other. Provision is made between the first and the second rotating ring for a torsion spring to suppress torsional vibrations. A speed-adaptive absorber is affixed to the second rotating ring, the speed-adaptive absorber including at least one hub part that is rotatable about an axis of rotation, as well as a plurality of damper masses which are able to swivel at least in the circumferential direction about swivel axes that are set apart from the axis of rotation.
Claims19
A flywheel, comprising:
- a first rotating ring that is connectible to a drive shaft;
- a second rotating ring that is connectible to a driven shaft, the first and the second rotating rings being twistable relative to one another and being supported concentrically one inside the other about an axis of rotation;
- a torsion spring for the suppression of torsional vibrations, said torsion spring being located between the first and the second rotating rings;
- a speed-adaptive absorber, affixed to the second rotating ring, the speed-adaptive absorber comprising at least one hub part that is rotatable about the axis of rotation, as well as a plurality of absorber masses which are able to circumferentially swivel about swivel axes that are set apart from the axis of rotation
- wherein each absorber mass is supported in the hub part by two bolts that are spaced apart from each other in the circumferential direction and which extend parallel to the axis of rotation, the bolts being able to roll on curved paths which, in the region of the hub part, have a profile that is open in a U-shape in the direction of the axis of rotation, and which, in the area of the absorber masses, have a profile that is open in a U-shape in the opposite direction;
- the bolts being guided through a guideway on the sides facing away from the respective curved paths.
