Torsional vibration damper mounted in power train of motor vehicle, has energy storage device comprising rolling components that are arranged between disc shaped primary structure and rotatable annular secondary structure

摘要

The torsional vibration damper (1) has a disc shaped primary structure (10) that is positioned with respect to a main axis (X) of rotation. A rotatable annular secondary structure (20) is connected with disc shaped primary structure through an energy storage structure (30). The rolling components of energy storage device are arranged between disc shaped primary structure and rotatable annular secondary structure.
