Wheel with increased interior lip depth
View Patent ↗Disclosed are various embodiments of one-piece, and multi-piece wheels configured to provide increased interior lip depth. In one embodiment, an outer periphery of a curved center portion of a wheel is attached to a wheel barrel in an inboard region, and a portion of the center portion extends into the outboard region of the wheel. At least a portion of the wall of the wheel barrel preferably comprises a gradual slope, instead of a traditional wheel mounting drop, and thus the interior lip depth is not obstructed by the interior bulge generally created by such a drop. In other embodiments, a wheel mounting drop is configured to permit multi-piece wheels to be joined at or near one of the drop walls to allow the wheel center to be positioned further in the inboard direction than in traditional wheels.
1. A wheel configured to be mounted to a vehicle, the wheel comprising:
(a) a substantially circular inboard rim adapted to form a seal against a tire wall;
(b) a substantially circular outboard rim adapted to form a seal against a tire wall;
(c) a wheel barrel comprising an exterior surface and an interior surface, the wheel barrel extending between the inboard and outboard rims, and the interior surface of the wheel barrel comprising a first diameter near the outboard rim and a second diameter near the inboard rim, the first diameter being larger than the second diameter so that a majority of the interior surface between the inboard rim and the outboard rim comprises a substantially frusto-conical shape; and
(d) a wheel center, attached to the interior surface of the wheel barrel near the inboard rim, wherein at least a portion of the wheel center is positioned closer to the outboard rim than the inboard rim.
2. The wheel of claim 1 wherein a majority of the surface area of the wheel center has a curved shape.
3. The wheel of claim 1 wherein a portion of the wheel center is positioned near the outboard rim.
4. The wheel of claim 1 wherein the inboard and outboard rims have approximately the same diameter.
5. The wheel of claim 1 wherein the ratio of the distance between the outboard and inboard rims and the distance from the outboard rim to the point of attachment of the wheel center is between about 1 and 1.35.
6. The wheel of claim 5 wherein the ratio of the distance between the outboard and inboard rims and the distance between the inboard rim to the further inboard point on the wheel center is between about 1 and 1.25.
7. The wheel of claim 1 wherein the wheel comprises separable inner and outer portions.
8. The wheel of claim 7 wherein the curved wheel center is unitary with the outer portion of the wheel.
9. The wheel of claim 1 wherein the wheel center is unitary with the outer portion of the wheel.
10. The wheel of claim 1 wherein the wheel center is separable from the wheel barrel.
11. The wheel of claim 1 , wherein the interior surface of the wheel barrel comprises a substantially linear slope from the first diameter to the second diameter.
12. The wheel of claim 1 , wherein the entirety of the interior surface of the wheel barrel comprises a substantially frusto-conical shape.
