Abstract
A tuned vibration absorber is disclosed that includes a base, a spring mounted to the base, and a mass mounted to the spring. The absorber is particularly, advantageous when mounted to a specific vehicle component via a mounting bolt that is already employed to mount that particular component. For example, a tuned vibration absorber may be mounted to a cam cover bolt on a cam cover in order to absorb undesirable vibrations at a particular frequency.
Claims21
