Abstract
A non-pneumatic tire and wheel assembly incorporates a tire tread and a conventional vehicle wheel with an elastomer tire body element and integral wall elements extending radially inward from the tire body element for sealing engagement with the wheel. The tire body element includes multiple concentric layers with alternating spokes. A bonded multilayer cover may be employed which is received within a recess in an outer surface of the tire body element from the tire tread. An attachment plate is engaged to the cover and attached to the wheel.
Claims8
A non-pneumatic tire and wheel assembly comprising:
- a tire tread;
- a vehicle wheel incorporating a rim with inner and outer bead rings;
- a molded elastomer tire body element engaged at an outer circumference by the tread and having a plurality of concentric layers with alternating spokes;
- and,
- integral wall elements extending radially inward from the tire body element for sealing engagement with the wheel, the integral wall elements including beads for sealing engagement on the bead rings to form a pneumatic chamber.
A vehicle non-pneumatic tire and wheel assembly comprising:
- a vulcanized rubber tire tread having an outer sidewall;
- a steel wheel having a rim with inner and outer bead rings, said outer bead ring having a relief;
- a urethane tire body element engaged at an outer circumference by the tread and having an outer circumferential engagement dome engaging a mating depression in an inner wall of the tread, and further having two concentric layers with spokes alternating for symmetrical adjacent support of spokes in adjacent layers, the layers having an outer surface recessed from the outer sidewall of the tread and integral wall elements extending radially inward from the concentric layers, said integral wall elements terminating in inner and outer beads for engagement with the inner and outer bead rings of the wheel forming a pneumatic chamber;
- a bonded multilayer cover received within the recess from the outer sidewall of the tread;
- and,
- an attachment plate bonded to the cover and received within the relief of the outer bead, said ring attached to the wheel with releasable fasteners.
