The embodiments herein relate generally to automotive accessories. In particular, embodiments of the disclosed invention relate to devices that prevent brake dust away from an external surface on a tire rim.
A disc brake is a wheel brake which slows rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of calipers. The brake disc is usually made of cast iron, but may be made of composites such as reinforced carbon-carbon or ceramic matrix composites. The brake disc is connected to the wheel and/or the axle. To stop the wheel, friction material in the form of brake pads, mounted on a device called a brake caliper, is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop.
When braking force is applied, the act of abrasive friction between the brake pad and the rotor wears both the rotor and pad away. The “brake dust” that is seen deposited on wheels, calipers and other braking system components consists mostly of rotor material. Brake dust can damage the finish of most wheels if not washed off. Generally, a brake pad that aggressively abrades more rotor material away, such as metallic pads, will create more brake dust. Another solution, to removing brake dust is the brake dust seal.
Prior to embodiments of the disclosed invention, prior art brake dust seals were flimsy and had vent or holes which permitted brake dust to be deposited on the rim surface of a wheel. This problem was further exacerbated by the lack of a firm seal on the brake dust seal. Embodiments of the disclosed invention solve these problems.
A brake dust seal is configured to protect a wheel with a rim from brake dust coming from a brake proximate the wheel. The brake dust seal includes a solid panel covering a back of the wheel and connected to the wheel with a pliable seal that prevents the brake dust from getting to an outside of the rim.
In some embodiments, a mesh is joined to the pliable seal which is corrugated to provide cooling to the brake. A solid panel outer diameter is approximately equal to a rim inner diameter and a solid panel inner diameter is approximately three inches less than the solid panel outer diameter. The pliable seal can be firmly pinched in place by tightening lug nuts on the wheel.
The detailed description of some embodiments of the invention is made below with reference to the accompanying figures, wherein like numerals represent corresponding parts of the figures.
By way of example, and referring to
As noted above, brake dust seals are attached to wheels. Here, wheel W comprises tire T mechanically coupled to rim R. Rim R further comprises hub H. Wheel W is mechanically coupled to a brake with lug nuts (not shown) as is well known in the art.

Solid panel 12 has a solid panel outer diameter and a solid panel inner diameter. Likewise, rim R has a rim inner diameter and a rim outer diameter. In some embodiments, the solid panel outer diameter is approximately equal to the rim inner diameter. The solid panel inner diameter is three inches less than the solid panel outer diameter. Pliable seal 16 is about one and one half inches in diameter. In some embodiments, solid panel 12 can be held in place by tightening lug nuts on wheel W.
While these components can be made of known materials in a known manner, the following materials have been shown to be effective. Solid panel 12 should be made from aluminum. Corrugated covering 18 can also be made from aluminum. Pliable seal 16 can be made from one half inch neoprene. In some embodiments, coupler 20 is a ¼ inch steal coupler.
Corrugated covering 18 can be used to dissipate heat from solid panel 12. However, corrugated covering 18 may not be used in all embodiments, when corrugated cover 18 is used it is held in place with pliable seal 16.
Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
