US Patent 11591005 Tunable dynamic absorber for attenuating vibration

A dynamic vibration absorber for reducing steering wheel vibration. The vibration absorber includes a resilient member that includes a resilient member inner surface that defines a center cavity that is configured to receive a steering column of a vehicle that generates vibration that is transferred to a steering wheel via the steering column, the center cavity being substantially coaxial with the steering column when attached thereto. The resilient member includes at least one resilient member outer surface that defines a resilient member outer diameter. The vibration absorber includes a rigid body that engages and is supported by the resilient member and that includes six degrees of freedom of movement relative to the steering column, the rigid body including a rigid body inner surface that defines a rigid body center cavity.
