Abstract: A system for detection of non-pneumatic tire loading includes a non-pneumatic tire. The non-pneumatic tire includes a ground-contacting annular tread, a central rim, and at least one spoke disk disposed between the rim and the tread. The spoke disk includes an inner ring mounted on the central rim, an outer ring, and spokes extending radially between the inner ring and the outer ring. A shear band is disposed between the outer ring of the spoke disk and the tread. A flange is disposed on an outboard surface of the spokes of the spoke disk. Indicating means are formed on the outboard surface of the plurality of spokes of the spoke disk radially outwardly of the flange. The flange interfaces with the indicating means when the tire is in an overloaded state or is in need of replacement.

Abstract: The invention relates to a method and a device for producing an annular multiaxial laid fabric and to an annular object produced therewith. The object of the invention is therefore to create a method and a device for forming a multiaxial laid fabric for annular structures which has no twisting or displacement of the thread layers. Furthermore, it should no longer be necessary to close a butt join or overlap separately to form a closed ring of the multiaxial laid fabric. This object is achieved in that at least a lower thread layer (2a) and an upper thread layer in the form of an endless thread array or an endless single thread, or in the form of thread-array sections or single-thread sections, are laid around the entire circumference of two mutually spaced ring elements (3) with differing thread orientations, and the first and upper thread layers (2a, 2b) are then fixed to each other at points.

Abstract: A nonpneumatic tire and wheel assembly which includes a wheel, and a spoke ring structure having an inner ring that is mounted on an outer surface of the wheel. The spoke ring structure has a plurality of spoke members, and an outer tread ring is mounted on the outer circumference of the spoke ring.

Abstract: A non-pneumatic tire includes a shear band having a first membrane layer located radially inward of the outer annular tread, a second membrane layer located radially outward of the first membrane layer, wherein the first and second membrane layer are formed of a plurality of parallel reinforcement cords arranged at an angle of 10 degrees or less with respect to the tire equatorial plane, said outer annular tread further comprises a first angled belt located radially outward of the second membrane layer, and a second angled belt located radially outward of the first angled belt, wherein the first and second angled belt each have parallel reinforcement cords having a belt angle in the range of 15-30 degrees with respect to the tire equatorial plane, and wherein the angle of the second angled belt has an angle equal and opposite direction of the belt angle of the first angled belt.

Abstract: The invention provides in a first aspect a non-pneumatic tire and wheel assembly comprising an outer annular ring having a ground contacting tread portion and a shear band, one or more spoke disks, wherein each spoke disk is connected to the shear band, wherein each spoke disk has at least two spokes, wherein each spoke has a first leg and a second leg, wherein a continuous strip of reinforcement is received in the first leg and the second leg.
