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.
Abstract:
The invention provides a non-pneumatic tire which can improve a riding quality, a noise performance and the like while improving a durability, and can further sufficiently suppress a buckling of a ground portion between spokes, because a circumferential fluctuation of a tire rigidity is hard to be generated due to a positional relationship between a spoke position and a center position of the ground surface, and a strain can be dispersed into each of portions of a support structure body. In a non-pneumatic tire T comprising a support structure body SS supporting a load from a vehicle, the support structure body SS includes an inner annular portion 1, an intermediate annular portion 2 concentrically provided in an outer side of the inner annular portion 1, an outer annular portion 3 concentrically provided in an outer side of the intermediate annular portion 2, a plurality of inner coupling portions 4 coupling the inner annular portion 1 and the intermediate annular portion 2, and a plurality of outer coupling portions 5 coupling the outer annular portion 3 and the intermediate annular portion 2, and the number of the outer coupling portions 5 is larger than the number of the inner coupling portions 4.
Abstract:
A compound solid tire capable of preventing a core tire from being displaced from a cover tire and preventing the side part of the cover tire from opening, comprising the core tire formed of an annular elastic body and the annular cover tire having an inner peripheral surface fitted to the outer peripheral surface of the core tire, the cover tire further comprising a tread part and side parts, wherein the inner peripheral length of the cover tire at the inner peripheral surface center position is set to 92 to 99.5% of the outer peripheral length of the core tire at the outer peripheral surface center position.
Abstract:
A resilient tire that supports a load without internal air pressure includes a ground contacting tread portion and sidewall portions extending radially inward from said tread portion and anchored in bead portions adapted to remain secure to a wheel during rolling of the tire. A bias ply carcass extends between the beads to support the sidewalls. A reinforced annular band is disposed radially inward of the tread portion. The band comprises an elastomeric shear layer at a radially outer side of the bias ply carcass and a membrane adhered to a radially outward side of the elastomeric shear layer. Each of the bias ply and membrane has a longitudinal tensile modulus sufficiently greater than the shear modulus of the shear layer so that when under load the ground contacting portion of the tire deforms to a flat contact region through shear strain in the shear layer while maintaining constant the length of the membranes.
Abstract:
A puncture proof vehicle tire comprising two symmetrical halves mounted on a divided felly, wherein the tread and the foot of each tire half are connected by a resilient, reinforcing connecting portion which comprises a plurality of supporting members having been formed by axial cut-outs. It is preferred to arrange the axial cut-outs in such a way, that the supporting members of the connecting portion are segment-like and alternately arranged in opposite directions and thus in successive segments are orientated alternately towards the felly edge and the felly center.
