Abstract
A frequency-tuned vibration damper device and assembly which may be used in steering wheels for motor vehicles is provided. Elastomeric stiffening bridges or connectors, integrally formed in elastomeric damper bodies, are used to obtain different damping frequencies in different spatial directions (y, z). Stiffening in specific direction(s) (y) allows larger frequency differences to be achieved. Asymmetric elastomeric damper bodies are arranged to operate with a combination of compression-mode damping and shear-mode damping along a first axis (y), and dominantly with a shear-mode damping along a different, second direction (z).
