Abstract

A hybrid wheel for vehicles that includes a unitary lug structure, with a mount face and a dish section of the lug structure extending therefrom. The lug structure is usually a cast aluminum alloy. A wheel structure including a high strength polymer encapsulates a portion of the lug structure dish section. Rim ring(s) are included in the wheel structure and are preferably made of a fiber reinforced high strength polymer.

First claim

What is claimed is:

1. A hybrid wheel, comprising:
a unitary lug structure having a mount face and a dish section extending from the mount face;
a wheel structure comprised of a polymer encapsulating a portion of the lug structure dish section and extending from the lug structure,
the wheel structure having an inner rim section and an outer rim section;
a lip section of the unitary lug structure within the inner rim section of the wheel structure, wherein the polymer of the inner rim section of the wheel structure encapsulates the lip section of the unitary lug structure;
a plurality of lug openings in the unitary lug structure mount face,
a lug reinforcement rib in the unitary lug structure mount face adjacent each lug opening, and
a plurality of wheel structure reinforcement ribs in the wheel structure extending from the lug structure.

2. The hybrid wheel of claim 1 ,
further comprising an outer rim ring within the outer rim section, wherein the polymer of the outer rim section encapsulates the outer rim ring.

3. The hybrid wheel of claim 2 ,
wherein the outer rim ring is comprised of a polymer.

4. The hybrid wheel of claim 2 ,
further comprising a strengthening ribbon within the outer rim ring.

5. The hybrid wheel of claim 3 ,
wherein the outer rim ring polymer includes glass fiber orientated substantially cylindrically around the outer rim ring.

6. The hybrid wheel of claim 3 ,
wherein the outer rim ring polymer includes glass fiber orientated substantially radially from a radial center of the hybrid vehicle wheel.

7. The hybrid wheel of claim 1 ,
wherein the unitary lug structure is comprised of a cast aluminum alloy.

8. The hybrid wheel of claim 1 ,
further comprising a plurality of lightening openings in the unitary lug structure mount face.

9. A method of manufacturing a hybrid wheel, comprising:
casting a unitary lug structure having a mount face, a dish section extending from the mount face, and a lip section;
injection molding a wheel structure comprised of a polymer to encapsulate a portion of the lug structure dish section such that the wheel structure extends from the unitary lug structure, and wherein the wheel structure has an inner rim section and an outer rim section;
wherein injection molding the wheel structure includes encapsulating the lip section of the unitary lug structure in the inner rim section of the wheel structures;
forming a plurality of lug openings in the unitary lug structure mount face,
providing a lug reinforcement rib in the unitary lug structure mount face adjacent each lug opening, and
providing a plurality of wheel structure reinforcement ribs in the wheel structure extending from the lug structure.

10. The method of manufacturing a hybrid wheel of claim 9 ,
further comprising injection molding an outer rim ring within the outer rim section, wherein the polymer of the outer rim section encapsulates the outer rim ring.

11. The method of manufacturing a hybrid wheel of claim 10
wherein the outer rim ring is comprised of a polymer.

12. The method of manufacturing a hybrid wheel of claim 11 ,
further comprising providing a strengthening ribbon within the outer rim ring.

13. The method of manufacturing a hybrid wheel of claim 11 ,
wherein the outer rim ring polymer includes glass fiber orientated substantially cylindrically around the outer rim ring.

14. The method of manufacturing a hybrid wheel of claim 11 ,
wherein the outer rim ring polymer includes glass fiber orientated substantially radially from a radial center of the hybrid vehicle wheel.

15. The method of manufacturing a hybrid wheel of claim 9 ,
wherein the unitary lug structure is comprised of a cast aluminum alloy.

16. The method of manufacturing a hybrid wheel of claim 9 , further comprising providing a plurality of lightening openings in the unitary lug structure mount face.

17. The hybrid wheel of claim 1 ,
wherein the inner rim section of the wheel structure includes a bead; and
the lip section of the unitary lug structure includes a radially outer portion within the bead of the inner rim section.

18. A hybrid wheel, comprising:
a unitary lug structure having a mount face and a dish section extending from the mount face,
a wheel structure comprised of a polymer encapsulating a portion of the lug structure dish section and extending from the lug structure,
the wheel structure having an inner rim section and an outer rim section,
a lip section of the unitary lug structure within the inner rim section of the wheel structure, wherein the polymer of the inner rim section of the wheel structure encapsulates the lip section of the unitary lug structure,
wherein the unitary lug structure includes a return section and a bend connecting the lip section to the dish section, and
wherein the return section, bend, and dish section define a concave gully of the unitary lug structure.
