MASS DAMPER

摘要

A tuned vibration mass damper for isolating vibrations from the steering wheel or other vehicle component includes an elastically cantilever mounted lead mass and a unitary thermoplastic bracket member made from a super tough plastic material and including a first or coupling portion for coupling the tuned vibration damper to a structure of the vehicle, a second portion for coupling the unitary bracket member to the lead mass, and an intermediate bight portion. The second coupling portion includes a plurality of cylindrically shaped legs extending through holes in the lead mass and having their ends formed (in a heading operation) to couple the unitary bracket member to the lead mass and a pair of travel limiters extending beyond the mass for preventing the mass from contacting other structures once the mass damper is installed.
