ARRANGEMENT FOR VIBRATION DAPING IN A STEERING COLUM

摘要

The invention relates to an arrangement for damping vibrations in a vehicle steering wheel mounted on a steering main shaft connected to a pair of steered wheels via a steering linkage. According to a preferred embodiment, the steering main shaft comprises an inner or outer hollow portion along its longitudinal axis, which portion is filled with a granular material to a predetermined level. This level is proportional to the shape and cross-sectional area of the hollow portion and also the frequency range of the vibrations to be damped. By measuring the dimensions of the hollow portion, the volume of a predetermined material with a given density which is required in order to damp vibrations in a frequency range applying for the vehicle can be calculated.
