This disclosure relates to hybrid wheels for vehicles. More specifically, this disclosure concerns, wheel assemblies for the off road power sports product market, trailers and light trucks.
Off road power sport vehicles, trailers, and light trucks are utilized for both work and recreation purposes. Consumers purchasing all-terrain vehicles (ATV), utility terrain vehicles (UTV), rugged terrain vehicles (RTV), side-by-side vehicles, trailers, or light trucks often consider not only function and performance, but also style of a vehicle and accessories.
Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, with emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Described below are various embodiments of the present systems and methods for wheel assembly. Although particular embodiments are described, those embodiments are mere exemplary implementations of the system and method. One skilled in the art will recognize other embodiments are possible. All such embodiments are intended to fall within the scope of this disclosure. Moreover, all references cited herein are intended to be and are hereby incorporated by reference into this disclosure as if fully set forth herein. While the disclosure will now be described in reference to the above drawings, there is no intent to limit it to the embodiment or embodiments disclosed herein. On the contrary, the intent is to cover all alternatives, modifications and equivalents included within the spirit and scope of the disclosure.
The present disclosure relates to rim and wheel assemblies for the off road power sport product market, trailers, and light trucks. Power sport products include all-terrain vehicles (ATV), utility terrain vehicles (UTV), rugged terrain vehicles (RTV), and side-by-side vehicles. For example, off road vehicles can be utilized for ranching or farming tasks, towing heavy loads, hauling cargo or tools to remote locations, hunting, or other sporting activities. Wheels designed for these vehicles must be able to endure the rough conditions that most users will be operating the vehicles. Likewise, trailers and light trucks may be used for similar tasks. These vehicles may have various tire pressures, use a tire liner, be foam filled, or other configuration. Consumers often consider not only function and performance, but also style of the vehicle and accessories. Customization of the vehicles is desired with some owners seeking more visually appealing wheels.
Aluminum alloy wheels are often used on vehicles such as automobiles and light weight trucks to provide a clean upscale appearance. Owners of off road power sport vehicles or utility vehicles, such as light trucks or trailers, are seeking a similar appearance, but using aluminum alloy wheels for an off road application can be impractical. A wheel that provides the strength and durability of steel and appearance of an aluminum, magnesium, alloy, carbon fiber, polyamide, or other composite wheel is desirable.
In various aspects, a hybrid wheel is provided to address such interests. The hybrid wheel can include a functional rim, a center disc, and a decorative wheel face insert. The functional wheel rim can be made from steel, high strength steel, a composite material or an alloy. In various aspects the functional wheel rim is made of a high strength material, with yield strength of about 35 ksi—about 86 ksi, and any range in between. A non-limiting example of a high strength material is high strength steel. The center disc can be made from steel, high strength steel, a low strength mild steel, a composite material, or an alloy. In various aspects, the center disc is made of a high strength material. In various aspects, the center disc is made of the same material as the material for the functional wheel rim with a yield strength of about 35 ksi—about 86 ksi. The wheel face insert can be made of aluminum, aluminum alloy, magnesium, polyamide, composite, carbon fiber, plastic, or some other material that can be used to provide a decorative insert such as providing the appearance of aluminum and/or an aluminum wheel on the first surface. In various aspects, the wheel face insert is made of a material that is different than the material for the functional wheel rim. In various aspects, the wheel face insert is made of a material having a lower strength than the material of the functional wheel rim. In some aspects, wheel face insert can be one piece. In other aspects, to accommodate deeper wheel offsets, the wheel face insert can include a rim flange cap ring and at least a wheel center face insert.
