Device for damping rotating shaft vibrations of vehicle, has piezoelectric element with electrical connections to circuit with heat dispersing elements to which generated electrical energy is fed

摘要

The device has a piezoelectric element (2) for application to a shaft (1) and that has electrical connections (3,4) and an electric circuit (5) with at least one heat dispersing element connected to the electrical connections so that electrical energy generated in the piezoelectric element is fed to the heat dispersing element(s). An Independent claim is also included for a vehicle component, especially a shaft, with an integral damper.
