Patent ID: 8657692

Claim:
A torsion vibration damper for a drive train of a motor vehicle, in particular a drive train of a hybrid vehicle, comprising: a spring support ( 10 ) and a force transmission flange ( 20 ) configured rotatable relative to the spring support ( 10 ), wherein at least one compression spring ( 30 ) is provided between the spring support ( 10 ) and the force transmission flange ( 20 ) for transferring a mechanical torque, wherein a housing ( 12 ) of the spring support ( 10 ) is configured so that in a radial direction of the torsion vibration damper ( 1 ) at least one longitudinal end of the compression spring ( 30 ) is supported at/in the spring support housing ( 12 ) and/or a clearance ( 40 ) remains between windings of a center section of the compression spring ( 30 ) and a wall of the spring support ( 10 ): wherein the compression spring ( 30 ) is a straight compression spring ( 30 ), wherein the spring support housing ( 12 ) includes a u-shaped ring channel ( 130 ) in which the straight compression spring ( 30 ) is partially received in a radial direction and in an axial direction of the torsion vibration damper ( 1 ), wherein an actuation hook ( 142 ) is provided for a support and/or an actuation of the straight compression spring ( 30 ) in the u-shaped ring channel ( 130 ) of the spring support housing ( 12 ) caused by the spring support housing ( 12 ), wherein a respective longitudinal end of the straight compression spring ( 30 ) contacts the actuation hook or is contactable at the actuation hook, and wherein the actuation hook ( 142 ) is provided at a support device ( 14 ) which is in particular configured as a support ring ( 14 ) which is attached in the spring support housing ( 12 ), wherein the actuation hook ( 114 ) of the support device ( 14 ) extends into the u-shaped ring channel ( 130 ).
