Torsional vibration damper has at least one energy storage device with polished region on windings at least in segments of its section facing guide device

摘要

The device has at least one damping device with input and output pats, one of which has a guide device for at least one energy storage device that enables relative movement of the energy storage device in the peripheral direction and support at least essentially in the radial direction against the action of a revolution rate-related centrifugal force. At least one energy storage device (86) has a polished region (148) on windings at least in segments (142) of its section (144) facing the guide device.
