Abstract:
1. A torsional vibration damper comprising: a divided flywheel including a primary flywheel connectable with a drive shaft of an engine and a secondary flywheel connectable with an input shaft of a transmission through a friction clutch, wherein the primary and secondary flywheels are rotatably supported relative to each other by a bearing and are movable relative to each other about an axis of rotation in opposition to the operation of at least one energy storage device, whereby both flywheels have regions by means of which the energy storage device is disposed in a circumferential direction of the torsional vibration damper and is compressible, at least one of the relatively rotatable flywheels has a wall region that bounds an annular chamber and that axially overlaps at least radially outer regions of the energy storage device and extends along the energy storage device, wherein the energy storage device includes at least two circumferentially arranged energy storage components and is radially outwardly supported by at least one support element that is arranged between the energy storage device and the wall region and that is movable along the wall region upon compression of the energy storage device, whereby the support element has at least one support shoe engaging at least one region of the energy storage device, and at least one roller body is provided between the support shoe and the wall region for rolling movement along a surface carried by the support shoe and including an intermediate element provided between the wall region and the at least one roller body, wherein the intermediate element is movable along the wall region and forms a support surface for the at least one roller body.
