The vibration absorbers have mounts for radial fastening of the vibration absorber to an inside surface of a wheel rim to be used on rails. A plurality of mounts are uniformly distributed over the circumference of the inside surface and are each coupleable to the wheel rim in an acoustically good conducting manner against a surface that matches the radius of curvature of the inside surface. On each mount at least one vibration absorber consisting of a sequence, running in the radial direction, of metal and plastic plates can be coupled in an acoustically effective manner by means of a coupling surface. The vibration absorbers and mount are releasably connected with one another and have a coupling surface that is always the same and is independent of the radius of curvature of the inside surface of the wheel rim.

Vibration absorber with mount

A resonance absorber for the damping of structure-borne vibrations has a number of freely swinging slats with different resonance frequencies. The slats are arranged on a common base which can be connected with a body to be damped, and are constructed as double slats comprising a damping coating which is in each case squeezed between the two slats elements.
