Abstract
A vibration absorber includes an absorber mass and at least one spring element formed of an elastomer material. The absorber mass is arranged for movement on the spring element and is movable with a phase displacement relative to vibrations introduced due to operating conditions. The spring element is fixed on a vibration generator. A supplementary spring is assigned to the spring element and acts in parallel therewith to compensate for temperature effects. The supplementary spring has a spring stiffness. An aid is provided for changing the spring stiffness of the supplementary spring.
