Abstract
An exemplary embodiment includes an automotive brake component, such as a brake drum or a brake rotor, and an inlay coupled to the automotive brake component. The inlay constituting at least a portion of a braking surface that is acted upon during a braking event. The inlay damping vibrations in the automotive brake component when the component is vibrated.
Claims19
A product comprising:
- a drum for a drum brake assembly, the drum having a web portion and a hoop portion extending from the web portion;
- and
- at least one inlay located at the hoop portion and constituting at least a portion of a braking surface contacting a braking component, the inlay damping vibrations in the drum when the drum is vibrated.
A product comprising:
- a drum for a drum brake assembly, the drum comprising a first material and having a hoop portion;
- and
- at least one inlay located at the hoop portion and comprising a second material that is different than the first material, the inlay constituting at least a majority of an exposed braking surface contacting a braking component, wherein relative movement between the drum and the inlay damps vibrations in the drum when the drum is vibrated.
A method of making a product, the method comprising:
- placing an inlay in a mold cavity;
- positioning the inlay in the mold cavity so that, when finished, the inlay constitutes an exposed braking surface that during a braking event contacts a braking component;
- and
- filling the mold cavity with a molten material that, when solidified, will make a drum for a drum brake assembly, the drum having a web portion and a hoop portion extending from the web portion, the inlay being located at the hoop portion.
