Vehicle steering wheel vibration damping structure with airbag module
A recently granted patent (Publication Number: US11964720B2) discloses a vehicle steering wheel vibration damping structure designed to reduce steering wheel vibrations. The structure includes an airbag module serving as a damper mass, a steering wheel, and vibration damping parts that mount the airbag module to the steering wheel surrounding the center of steering. The damping parts consist of a first part positioned above the center of steering and a second part positioned below, with the first part having a lower spring constant or elastic modulus compared to the second part.
Furthermore, the patent details the specific composition of the damping parts, with the first part incorporating symmetrically arranged damping rubber on both sides of the center of steering, while the second part includes damping rubber with a higher hardness. Additionally, the structure includes individual springs attached to each damping part to provide elastic support, with the first spring having a lower spring constant than the second spring. The design also incorporates deadweight on the airbag module side near the installation height of the second damping part, with the deadweight positioned below this height to enhance vibration damping. The airbag module itself features a module base with a lighter upper region made of synthetic resin and a heavier lower region made of metal, contributing to the overall vibration damping effectiveness of the steering wheel device.
