Vehicle shaft for damping oscillations comprises planar sections on its periphery with piezo-modules applied over the whole surface of the planar sections

摘要

Vehicle shaft (1) comprises planar sections on its periphery with piezo-modules (3) applied over the whole surface of the planar sections. Preferred Features: The shaft has groves for receiving the piezo-modules. The piezo-modules have piezoelectric elements arranged over each other in layers. The piezoelectric elements are in the form of fibers embedded in a thin flexible support foil of each module.
