Abstract
A component defines at least one chamber that is confined by the component. The chamber has an inner surface. A filler material is disposed inside the chamber. Relative movement between the inner surface and the filler material helps dampen vibrations and other oscillations if and when the component is vibrated.
Claims20
A product comprising:
- a component defining at least one chamber confined by the component, the at least one chamber defined at least in part by an inner surface, a filler material being disposed within the at least one chamber, wherein relative movement between the inner surface and the filler material helps dampen vibrations in the component when the component is vibrated.
A product comprising:
- a brake rotor comprising:
- a hub portion;
- and
- a cheek portion extending from the hub portion and defining a chamber confined by the cheek portion, the chamber defined at least in part by an inner surface, a filler material being disposed within the chamber, wherein relative movement between the inner surface and the filler material helps dampen vibrations in the brake rotor when the brake rotor is vibrated.
