Thermoplastic wheel hub and non-pneumatic tire

A non-pneumatic wheel having a front and a rear comprising:

• an outer band, the outer periphery of said outer band having a tread for ground contact;
• an inner band;
• a plurality of web elements positioned between and connecting said outer band and said inner band;
• a thermoplastic 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 thermoplastic ribs extending radially outwardly from said center hub;
• and
• a thermoplastic cylindrical tire mount connected to said ribs and extending axially and substantially parallel to a central axis for mounting said inner band thereon.

A non-pneumatic wheel having a front and a rear comprising:

• an outer band, said outer band having a tread for ground contact;
• an inner band;
• a plurality of web elements positioned between and connecting said outer band and said inner band;
• a thermoplastic center hub for attachment to a wheel bearing of a vehicle, said center hub comprising a base wall extending radially and a side wall extending circumferentially and axially about said base wall, a central shaft aperture extending axially though said base wall and a plurality of lug apertures spaced radially from and circumferentially about said central shaft aperture and extending axially through said base wall and said side wall;
• a plurality of thermoplastic ribs extending radially outwardly from said side wall and spaced circumferentially about said center hub, said ribs having a uniform wall thickness;
• a thermoplastic cylindrical tire mount connected to said ribs and extending axially in substantially a cylinder such that said center hub is recessed relative to an outer axial periphery of said tire mount and cantilevered by said ribs to said tire mount, said tire mount having a substantially uniform wall thickness and a non-smooth outer tire mounting surface for mounting a non-pneumatic tire thereon;
• a plurality of compression limiters disposed in said lug apertures, one of said compression limiters being disposed in one of said lug apertures, each of said compression limiters having a cylindrical body extending axially with an aperture extending therethrough to receive a threaded fastener of the wheel bearing and being integral, unitary, and one-piece;
• and
• said center hub, said ribs, and said tire mount are made of a polymeric material reinforced by a plurality of fibers to be integral, unitary, and one-piece and said compression limiters being made as one-piece of at least one of a metal, composite, and ceramic material and secured to said center hub to be integral therewith.
