Rotary vibration damper for motor vehicle gearbox has spring seat element with arrangement for reducing wear on components that come into contact with spring seat element

摘要

The rotary vibration damper has a spring (7) inserted between the primary side inertial mass and a secondary side inertial mass (9) with the intermediate insertion of a spring seat element (55). The spring seat element has an arrangement (65a) for reducing wear on components that come into contact with the spring seat element. An independent claim is also included for a gearbox for a motor vehicle with an inventive device.
