Abstract
An insert has a body which defines a cavity with a filler held in the cavity. Relative movement between the body and the filler helps dampen vibrations in a component when the insert is carried in the component and when the component is vibrated.
Claims24
A product comprising:
- an insert having a body defining a cavity that extends from a first end that is closed to a second end that is closed, the insert having a filler held in the cavity, wherein relative movement between the body and the filler help dampen vibrations in a component when the insert is carried by the component and when the component is vibrated.
A product comprising:
- a component that is manufactured by a casting process;
- and
- at least one insert carried at least partially within the component, the at least one insert having a body defining a cavity with a filler held in the cavity, wherein the at least one insert helps dampen vibrations in the component when the component is vibrated.
A method of making a product, the method comprising:
- providing a body that is hollow between a first end and a second end;
- at least partially filling the body with a filler;
- closing the first end and the second end to define a cavity and to trap the filler within the body;
- and
- inserting the body at least partially within a component.

A product comprising:
- a brake rotor comprising:
- a cheek portion;
- a hub portion extending from the cheek portion;
- and
- an insert being cast over by the cheek portion to be bounded on all sides by the cheek portion, the insert having a body extending from a first end that is closed to a second end that is closed, the body defining a cavity between the first end and the second end, a filler being held within the cavity to help dampen vibrations in the brake rotor, the filler being composed of a first material and the body being composed of a second material, the first material having a lower melting temperature than that of the second material.
2 more elements
A method comprising:
- providing a self-contained dampening device in a body portion of a component;
- and
- inserting the self-contained dampening device in the body portion to dampen the component.
