Abstract

An improved vibration absorber that overcomes deficiencies of known heavy vibration absorbers that require exact manufacturing tolerance for the rigidity of the absorber in order to generate a sufficiently large frequency range of the vibration absorber. The new vibration absorber has the purpose of covering a larger frequency range with a lower weight by having the absorber mass disposed to be pivotable around a pivot at one end and on an opposite side supports itself on the vehicle body through at least one bearing arrangement. The absorber mass and/or the bearing arrangement are slideably arranged with respect to the pivot. The vibration absorber may be used in vehicles which have a natural vibration in the low frequency range.
