Torsional oscillation damper has primary and secondary sides, drive element, planetary wheel, engaging and counter-engaging formations, and torque transmission element

摘要

The torsional oscillation damper (10) comprises a primary side (12) connected or connectable to a drive element (24) in order for both to rotate on a first pivot axis. A secondary side (14) rotates on the first pivot axis against the action of a damping arrangement (16) in relation to the primary side. At least one planetary wheel (44) rotates on a second pivot axis in a staggered position in relation to the primary side, and has an engaging formation (45) engaging with a counter-engaging formation (42) on the primary and or secondary side which have a disc-type torque transmission element (18) comprising at least two parts (52,54) connected in a connecting part (56).
