Torsion vibration damper, especially for two mass oscillation wheel; has primary side and rotatable secondary side that rotates about axis against action of damper arrangement

摘要

The damper has a primary side (12) and a rotatable secondary side (14) that rotates about an axis (A) against the action of a damper arrangement (16). The primary side has a disc element (18) connected by at least one fixing screw (20) to rotate with a drive shaft (24). The secondary side is axially or radially supported in a bearing arrangement (54) connected to rotate with the drive shaft. The bearing arrangement a first bearing section (66,76) for a drive input shaft (78) under an intermediate arrangement of a first rotation bearing (80). An axial projection is provided at the first bearing section for the first rotation bearing.
