A torsional vibration damper for incorporation into the torque transmission path between two components or subassemblies, especially for a hydrodynamic coupling device, includes at least two disk-like damper members. Each damper member has a radially outward coupling region and a radially inward coupling region, and at least one deformation region extending between the radially outward coupling region and the radially inward coupling region. Each deformation region is elastically deformable at least in some areas to permit a relative circumferential movement between the radially outward coupling region and the radially inward coupling region.
A torsional vibration damper for incorporation into a torque transmission path between two components, said vibration damper comprising at least two disk-like damper members, each damper member having a radially outward coupling region and a radially inward coupling region, and at least one deformation region extending between the radially outward coupling region and the radially inward coupling region, each said deformation region being elastically deformable to permit a relative circumferential movement between the radially outward coupling region and the radially inward coupling region, at least one said radially inward coupling region and at least one said radially outward coupling region having tooth-like formations for mating with respective first and second components wherein the radially outward coupling region of one of said damper members mates with one of the two components, the radially inward coupling region of another of said damper members mates with the other of the two components, and the radially inward coupling region of the one damper member is connected to the radially outward coupling region of the another damper member via at least one further said damper member so that said damper members act in series for transmission of torque between said two components.
A hydrodynamic coupling device comprising a torsional vibration damper in a torque transmission path between a clutch member of a lockup clutch arrangement and a turbine wheel, said torsional vibration damper comprising at least two disk-like damper members, each damper member having a radially outward coupling region and a radially inward coupling region, and at least one deformation region extending between the radially outward coupling region and the radially inward coupling region, each said deformation region being elastically deformable to permit a relative circumferential movement between the radially outward coupling region and the radially inward coupling region, at least one of said radially inward coupling regions having tooth-like formations which mate with one of said clutch member and said turbine wheel, at least one of said radially outward coupling regions having tooth-like formations which mate with the other of said clutch member and said turbine wheel.
A hydrodynamic coupling device comprising a torsional vibration damper in a torque transmission path between a turbine wheel shell and a turbine wheel hub, said torsional vibration damper comprising at least two disk-like damper members, each damper member having a radially outward coupling region and a radially inward coupling region, and at least one deformation region extending between the radially outward coupling region and the radially inward coupling region, each said deformation region being elastically deformable to permit a relative circumferential movement between the radially outward coupling region and the radially inward coupling region, at least one of said radially inward coupling regions having tooth-like formations which mate with said turbine wheel shell, at least one other of said radially inward coupling regions having tooth-like formations which mate with said turbine wheel hub, at least two of said radially outward coupling regions being directly connected so that said at least two of said disk-like damper members act in series for transmission of torque between said turbine wheel shell and said turbine wheel hub.
