A non-pneumatic tire, comprising a polyurethane composite layer which comprises a polyurethane matrix material and a thermoplastic expandable polymer material dispersed in the polyurethane matrix material. The polyurethane matrix material is obtained by a reaction comprising the following components: (A1) a polyisocyanate composition; (B1) at least one polyalkylene oxide-based polyether polyol having a number average molecular weight of 2000-7000 g/mol, calculated according to GB/T 7383-2007: test method for hydroxyl value, and containing 15-35 wt % of solid particles based on the total weight of the polyether polyol; (B2) one or more chain extenders; (B3) one or more catalysts; and (B4) one or more foaming agents. Also provided herein is a method for preparing a non-pneumatic tire, a process for manufacture of a non-motor vehicle, and a non-motor vehicle.

The present invention provides an annular beam of monolithic construction of one homogeneous material and a related efficient, low-cost non-pneumatic tire. Specific geometric design, combined with nonlinear elastomer physical properties, enable the suppression of all reinforcing belts, continuous fibers, or other strengthening layers in the annular beam. The annular beam consists of at least two bands that are continuous in the circumferential direction and connected by a web geometry. The non-pneumatic tire consists of the annular beam, a ground contacting portion, a central wheel, and a plurality of web spokes that connect the wheel and beam. When the tire is loaded to a design load against a flat surface over a design contact length, a contact area of essentially uniform pressure is produced, while the load is transmitted from the beam to the hub via tension in the web spokes. The tire can be economically manufactured.

A non-pneumatic tire includes a support structure for supporting a load from a vehicle. The support structure includes an inner annular portion, an outer annular portion concentrically provided on an outer side of the inner annular portion, and a plurality of connecting portions which connect the inner annular portion and the outer annular portion to each other and are provided in a tire circumferential direction independently of one another, the plurality of connecting portions are configured such that elongated plate-like first connecting portions and elongated plate-like second connecting portions are arrayed along the tire circumferential direction, a plate thickness is smaller than a plate width, a plate thickness direction is oriented to the tire circumferential direction, and a plate thickness at a tire radial direction inner end coupled to the inner annular portion is larger than a plate thickness at a tire radial direction center portion.

A wheel and tire assembly includes a plurality of support elements for supporting part of a load of a vehicle and an annular shear band extending circumferentially around the support elements. The band has a radially inner circumferential membrane, a radially outer circumferential membrane, and a shear layer interconnecting the inner membrane and the outer membrane. The shear layer has a plurality of closed cells for controlling shear deflection between the inner membrane and the outer membrane.

A wheel for an autonomous cleaning robot that maneuvers the robot on a floor surface includes a tire having first and second opposing outer edges and a middle portion having a tread pattern between the first and second outer edges, the tread pattern comprising a plurality of raised tread having trenches therebetween. Each of the plurality of raised tread includes a first raised tread portion extending from the first outer edge to the middle portion and substantially perpendicular to the first and second outer edges; a second raised tread portion extending at an angle away from the first raised tread portion; and a third raised tread portion extending from the second raised tread portion to the second outer edge and substantially perpendicular to the first and second outer edges, the third raised tread portion being laterally offset from the first raised tread portion.

A wheel assembly includes a mounting plate for attachment to a rotatable axle, a plurality of elongate friction members for engaging a tire assembly, a plurality of first angular flanges extending radially outward and circumferentially in a first direction from the mounting plate, and a plurality of second angular flanges extending radially outward and circumferentially in a second direction, opposite the first direction, from the mounting plate. Each elongate friction member is disposed axially between one of the first angular flanges and one of the second angular flanges.

A shear band that may be used e.g., in a non-pneumatic tire is provided. The shear band uses interlaced reinforcing elements positioned within a shear layer of elastomeric material. A variety of configurations may be used to create the interlaced positioning of the reinforcing elements including e.g., a horizontal diamond or vertical diamond configuration. The shear layer formed from a rubber composition having a very low hysteresis.

A method for producing a tire filled with a (meth)acrylic hydrogel, the method comprises a) providing a mixture comprising at least one water-soluble (meth)acrylic compound, water and an initiator, and b) filling the mixture in a tire in which the mixture polymerizes to form the (meth)acrylic hydrogel. The tire filling material is suitable for producing flat proof tires, enables fast and controlled cure and is insensitive towards dosage errors. Moreover, the tire filling material is environmental friendly and cost effective.

A tire for a vehicle has a structure in which a plurality of air blocks are detachably mounted in a circumferential direction of the tire. The tire is similar to an airless tire, in which a plurality of spokes are connected to and arranged between a tread rim part configured to come into contact with a road surface and a hub which is mounted to the wheel, and the tire is also similar to a pneumatic tire, in which an air block is replaceably inserted and mounted into an air block mounting space formed between the spokes.
