Description
Technical Field
The present invention relates to filtering devices and more particularly to a wheel dust filter for an automobile that is placed between the hub of the disk brake rotor and the wheel of the automobile that has a central mounting plate having a central mounting hole defined therethrough and a plurality of lug apertures formed through the mounting plate and spaced around the central mounting hole; a circular frame rim having four sequentially spaced, rim filter receiving channels; four radially projecting frame rim supports each having two rim support filter receiving channels, each rim support being in connection between the frame rim and the central mounting plate in a manner to define four filter apertures; and four filter elements constructed from open cell foam, each filter element being positioned within one of the four filter apertures in a manner such that portions of the perimeter edge of each filter element are positioned within a rim filter receiving channel and two rim support filter receiving channels.
Background of the Invention
Many automobiles have wheels that accumulate brake dust from the wheel brake assembly. The brake dust is created when particles of the brake shoe are abraded from the brake shoe surface during braking of the automobile. Because the accumulated brake dust can detract from the appearance of the automobile, it would be a benefit to have a device for preventing this accumulation. Because ease of installation is always an import consideration, it would be a further benefit to have a device for preventing accumulation of brake dust on the wheel of an automobile that was easily installed. In addition, because the holes formed through the wheels provide a pathway for cooling air to cool the brake assembly, it would be a further benefit to have a device for preventing the accumulation of brake dust on the wheel that allowed air transmission through the wheel while preventing the passage of brake dust particles.
Summary of the Invention
It is thus an object of the invention to provide a wheel dust filter that prevents the accumulation of brake dust on an automobile wheel.
It is a further object of the invention to provide a wheel dust filter that is easily installed.
It is a still further object of the invention to provide a wheel dust filter that allows air transmission through the wheel while preventing the passage of brake dust particles.
It is a still further object of the invention to provide a wheel dust filter that is placed between the hub of the disk brake rotor and the wheel of an automobile tire that has a central mounting plate having a central mounting hole defined therethrough and a plurality of lug apertures formed through the mounting plate and spaced around the central mounting hole; a circular frame rim having four sequentially spaced, rim filter receiving channels; four radially projecting frame rim supports each having two rim support filter receiving channels, each rim support being in connection between the frame rim and the central mounting plate in a manner to define four filter apertures; and four filter elements constructed from open cell foam, each filter element being positioned within one of the four filter apertures in a manner such that portions of the perimeter edge of each filter element are positioned within a rim filter receiving channel and two rim support filter receiving channels.
It is a still further object of the invention to provide a wheel dust filter that accomplishes some or all of the above objects in combination.
Accordingly, a wheel dust filter is provided. The wheel dust filter comprises a central mounting plate having a central mounting hole formed therethrough and a plurality of lug apertures formed through the mounting plate and spaced around the central mounting hole; a circular frame rim having four sequentially spaced, rim filter receiving channels; four radially projecting frame rim supports each having two rim support filter receiving channels, each rim support being in connection between the frame rim and the central mounting plate in a manner to define four filter apertures; and four filter elements constructed from open cell foam, each filter element being positioned within one of the four filter apertures in a manner such that portions of the perimeter edge of each filter are positioned within a rim filter receiving channel and two rim support filter receiving channels. In a preferred embodiment the central mounting plate, the frame rim supports and the frame rim are integrally formed from a plastic material. In another preferred embodiment, the perimeter edges of each of the filter elements is ultrasonically welded to the central mounting plate, two of the frame rim supports and the circular frame rim.
In use, the wheel dust filter is positioned over the brake assembly of an automobile wheel assembly by inserting the lugs of the wheel assembly through the lug apertures prior to positioning the wheel onto the wheel assembly in the convention fashion. The filter elements provide a pathway for cooling air to reach the brake assembly while minimizing migration of brake dust from the brake assembly to the exterior surface of the wheel.
