The present disclosure generally relates to a brake dust seal configured to protect a wheel with a rim from brake dust coming from brake pads near the wheel.
Most passenger vehicles rely upon disk brakes having a wheel rotor that rotates with the corresponding wheel. Two stationary brake pads are positioned closely on the inside and outside of the rotor. In response to a braking command, a caliper asserts a closing force on the brake pads to grip the rotor, causing frictional slowing of the rotor and thus the wheel. The abrasive material of the brake pads wears off during use creating brake dust that tends to discolor the exposed portions of the wheel rim.
The description of the illustrative embodiments can be read in conjunction with the accompanying figures. It will be appreciated that for simplicity and clarity of illustration, elements illustrated in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements are exaggerated relative to other elements. Embodiments incorporating teachings of the present disclosure are shown and described with respect to the figures presented herein, in which:
A wheel shield includes a central disk having a central wheel hub opening surrounded by annularly spaced stud holes that correspond to a pattern presented by a vehicle. The central disk includes an outwardly open fastening surface such as a channel positioned around an outer diameter of the central disk. The wheel shield includes a radially-compressible ring such as radially extending filaments. In one or more embodiments, the radially-compressible ring has an inner diameter attached in the outwardly open fastening surface of the central disk and sized to engagingly contact an inner diameter of a vehicle wheel rim to restrict movement of brake dust to an exposed outer surface of the vehicle wheel rim while still allowing for the movement of air for cooling.
The purpose of the wheel shield is to prevent corrosive particles that result from braking mechanisms of automobiles (commonly known as brake dust) from reaching and collecting on the outer visible portion of an automobile wheel. This is accomplished by placing the shield between the automobile wheel and the braking mechanism, so that the particles are contained to the inner, non-visible side of the wheel.
The brake dust shield can be made up of two main components. A circular solid panel and an outer ring-shaped brush made from a plurality of filaments. The solid panel and the brush filaments work in conjunction to create a shield between the automobile braking mechanism and the outer visible portion of the wheel. Though a solid panel has been used in similar applications, they pale in comparison to the versatility of the wheel shield's ability to conform to many different wheel sizes, profiles, and designs when the filaments are added to the perimeter of the solid panel. The flexibility of the filaments allows the shield to conform to nearly any wheel profile, size or design without compromising its intended function and eliminates the need to manufacture a custom panel specific to the wheel to be protected. In addition, the loose filaments allow for the movement of air for cooling of the disk brake components. Both main components of the invention can be made from a number of different materials.
By surrounding the solid panel with a ring-shaped brush, the bristles create a wall that substantially blocks a large portion of dust and particles while still being air permeable. With an air permeable wall, the vehicle's movement can create the air flow necessary to cool the inner brake components while also enabling the removal of much of the dust and debris that would otherwise accumulate during use.
The brush may also be made of any suitable material and configured with filaments that are of sufficient length and thickness that the ring-shaped brush remains flexible to help conform to the shape of the wheel and substantially air permeable. In one or more embodiments of the invention, the brush may be made of synthetic bristles, such as nylon, or natural bristles, such as hair.
In one or more embodiments of the invention, the brush bristles (filaments) extend toward the vehicle wheel rim and may be long enough to touch the vehicle wheel rim. The bristles create an air permeable wall suitable to allow air to flow through while blocking a substantial portion of dust and particles. In alternate embodiments of the invention, the bristles do not extend far enough to touch the vehicle wheel rim while connected to the wheel. The series of bristles of the ring-shaped brush create an air permeable wall capable of allowing air to flow through or around the series of bristles.
In one or more embodiments of the invention, the outer ring-shaped brush component is not permanently affixed to the circular solid panel and is easily replaced with replacement outer ring-shaped brush components when the brush begins to lose efficiency due to wear and tear or clogging with dust, dirt, grime or other contaminants.
Solid panel may be comprised of many different materials including but not limited to, metal, plastics, rubbers, carbon fiber, fiber glass, or any other suitable material.
The outer ring-shaped brush has a brush inner diameter and brush outer diameter while the vehicle wheel rim has a rim inner diameter and a rim outer diameter. In one or more embodiments, the brush outer diameter is approximately equal to the rim outer diameter. In one or more embodiments, the filaments of the outer ring-shaped brush are about one inches to 12 inches in length. In some embodiments, solid panel can be held in place by tightening lug nuts on the vehicle wheel rim.
Filament may be comprised of many different types of material as well. Including but not limited to: metal, plastic, rubber, fiber glass, carbon fiber, nylon, animal hair, silicone, etc. Filament material may be coupled to solid panel in a number of different ways. One of which being a circular channel or track fastened to perimeter of solid panel with filament fastened in channel. The wheel shield can be held in place with the same studs and lugs that hold the wheel in place.
The solid panel is adapted for receiving the hub of an automobile. In one or more embodiments, the wheel shield is placed on the vehicle hub just as the wheel would be, then followed by the wheel and secured when wheel lug nuts are tightened, pinching it between the wheel and the hub.
Some, or all of wheel shield may be painted or customized as to preferred aesthetic appeal.
In some instances, the solid panel maybe altered with openings or holes to allow air to pass through for cooling purposes. A suitable, replaceable filter material may be placed over said openings or holes to prevent brake dust from passing through.
In some instances, a heat resistant insulation type material may be used with filament, to prevent filament from being exposed to extreme heat generated by braking mechanism of automobile.
