Abstract

An installation for damping vibrations in the drive connection of a motor vehicle by a vibration absorber which includes, in coaxial arrangement with the cardan shaft, an annular vibrating mass, a carrier flange adapted to be secured to the cardan shaft, and a resilient body of an elastomeric material which effects the vibration coupling of the vibrating mass with the carrier body of the carrier flange; stiffening elements are inserted into the resilient body which serve as stiffening elements effective in the radial direction; additionally apertures are provided in the resilient body on both sides of the stiffening elements which enable an intentional reduction of its torsional stiffness so that a resonant frequency rate f.sub.r /f.sub.t of 2.5 or more can be realized for the vibration absorber.
