摘要： Disclosed is a dynamic damping device for a steering system of an automotive vehicle, which equipped with a telescopic steering column, including a plurality of mutually independent dynamic dampers, each including a mass member and a spring member for elastically supporting the mass member to the steering column or wheel. At least two of natural frequencies of the plurality of dynamic dampers are tuned to a higher and a lower frequency range in relation to a central value of a range of variation in a natural frequency of the steering wheel due to an expansion or contraction of the telescopic steering column, within the range of vibration in the natural frequency of the steering wheel. Further, a difference between adjacent ones of the natural frequencies of the plurality of dynamic dampers is made held within 10-40% of the central value of the range of vibration in the natural frequency of the steering wheel.

摘要： A double-mass type dynamic damper mounted on a rod-shaped oscillating member, which includes a first damper system and a second damper system that are tuned to two different frequency ranges. Each of the damper systems includes a cylindrical mass member disposed radially outwardly of the oscillating member, and an elastic support member for elastically supporting the mass member with respect to the oscillating member. The elastic support members of the two damper systems are disposed in series and connected to each other in the axial direction. The dynamic damper further includes an elastic connector formed by adjacent parts of the two elastic support members, for elastically connecting axially opposed faces of the two mass members. The two elastic support members have respective spring constants as measured in the radial directions, which spring constants are both larger than a shearing spring constant of the elastic connector that is subjected to shearing stresses upon relative displacement of the mass members in the radial directions.
