摘要： A non-pneumatic tire includes an annular inner ring, an annular outer ring, and a support structure extending from the annular inner ring to the annular outer ring. The support structure includes a plurality of spokes, webbing, cells, or other open-sided support structure. The tire includes a bump stop. The bump stop includes an inner member radially extending from a radially outer surface of the annular inner ring. The inner member has a radially outer surface facing a radially inner surface of the annular outer ring. The bump stop includes an outer member radially extending from a radially inner surface of the annular outer ring. The outer member has a radially inner surface facing a radially outer surface of the annular inner ring.

摘要： A non-pneumatic tire includes a plurality of axially adjacent wheel portions. Each wheel portion has an inner ring, an outer ring, and a flexible, interconnected web extending between the inner ring and the outer ring. The flexible, interconnected web includes a plurality of web sectors disposed circumferentially about the tire to form a generally annular web. Each of the plurality of web sectors is hingedly connected to a pair of oppositely adjacent web sectors.

摘要： This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be greater than the average thickness (T2) of the rim part. In other words, the relation T1>T2 holds.

摘要： A method of assembling spokes into a non-pneumatic tire (10) is provided in which a shear band (16) is located outward from a hub (12) in a radial direction. A segment (20) is present that has a plurality of spokes (22), and both inner and outer radial bonding ends (24, 26). The plurality of spokes (22) engage both of these bonding ends (24, 26). The outer radial bonding end (24) is attached to the shear band (16) using adhesive (28), and the inner radial bonding end (26) is attached to the hub (12) using adhesive (28). This segment (20) extends less than 360 degrees about the central axis (14) in a circumferential direction.
