Abstract

A thermoplastic wheel hub ( 10 ) includes a center hub ( 26 ) for attachment to a wheel bearing ( 20 ) of a vehicle. The center hub ( 26 ) has a central shaft aperture ( 28 ) extending axially therethough and a plurality of lug apertures ( 30 ) spaced radially from and circumferentially about the central shaft aperture ( 28 ). The thermoplastic wheel hub ( 10 ) also includes a plurality of ribs ( 40 ) extending radially outwardly from the center hub ( 26 ). The thermoplastic wheel hub ( 10 ) further includes a cylindrical tire mount ( 46 ) connected to the ribs and extending axially in substantially a plane for mounting a non-pneumatic tire ( 12 ) thereon.

Claims (12)

1. A thermoplastic wheel hub comprising:

a center hub for attachment to a wheel bearing of a vehicle, said center hub having a central shaft aperture extending axially therethrough and a plurality of lug apertures spaced radially from and circumferentially about said central shaft aperture;

a plurality of ribs extending radially outwardly from said center hub, in which pairs of the ribs form U-shaped apertures therebetween; and

a cylindrical tire mount connected to said ribs and extending axially for mounting a non-pneumatic tire thereon,

wherein said tire mount is an outermost layer of said wheel hub that is in direct contact with said plurality of ribs

wherein said center hub is cantilevered by said ribs to said tire mount and wherein each of said ribs have a reduced uniform wall thickness in aesthetic areas.

2. A thermoplastic wheel hub as set forth in claim 1 wherein said tire mount has a non-smooth outer tire mounting surface.

3. A thermoplastic wheel hub as set forth in claim 2 wherein said non-smooth outer tire mounting surface is adapted for adhering the non-pneumatic tire thereon by at least one of a surface roughness, mechanical bonding, surface treatment, and adhesion promoter.

4. A thermoplastic wheel hub as set forth in claim 2 wherein said non-smooth outer tire mounting surface includes at least one groove extending radially inward and axially along said tire mounting surface.

5. A thermoplastic wheel hub as set forth in claim 1 wherein said tire mount has a substantially uniform wall thickness.

6. A thermoplastic wheel hub as set forth in claim 1 wherein said ribs have a uniform wall thickness.

7. A thermoplastic wheel hub as set forth in claim 1 wherein said thermoplastic wheel hub is made from an injection molding process.
