A shear band comprising a three-dimensional spacer structure, wherein the three-dimensional spacer structure is formed from a first and second layer of material, each layer of material having first reinforcement members which extend in a first and direction, and second reinforcement members which extend in a second direction, wherein each layer of material is connected to each other by a plurality of connecting reinforcement members which extend in a third direction, wherein the shear band further comprises a first membrane layer located radially outward of the three-dimensional spacer structure. The invention further comprises a non-pneumatic tire which includes the above described shear band.

A non-inflatable tire for an agricultural implement, including a sole, a tread, and a pair of sidewalls connecting the sole to the tread is provided. A first sidewall extends from the sole to the tread, while the second includes an internal portion which extends from the sole to the tread and an external portion projecting from the tread. The first sidewall and the tread are designed so as to jointly hold the external portion of the second sidewall in line with the internal portion.

An airless flexible tire comprising a belt, drive lugs, and traction lugs. The drive lugs extend inwardly from the belt and form annularly spaced, rigid, high torque points. The traction lugs extend outwardly from the belt and are annularly offset from the drive lugs so as to form flexible sections that deflect radially inwardly when the tire engages the ground. Each traction lug has an effective height as a function of its actual height, the angle that the traction lug extends relative to a radial axis, the angle of the traction lug's distal surface, and the amount the tire deflects radially inwardly near the traction lug so as to at least partially equalize a rolling radius of the wheel to reduce torque generated near the high torque points.

In view of the above, the disclosure provides a non-pneumatic tire capable of enhancing a load supporting performance and a shock absorbing effect and improving a braking and traction performance. The present disclosure provides a non-pneumatic tire comprising a band part and a spoke part; where, a band part includes an inner band and an outer band that is separated from the inner band and surrounds an outer peripheral surface of the inner band; and where, a spoke part includes a plurality of first spokes that is arranged in a circumferential direction between the inner band and the outer band and connects the inner band and the outer band. Furthermore, according to another embodiment, a spoke part may include second spokes that connected to first spokes adjacent to each other at wherein first embodiment.

A mounting wheel (3) for a motor vehicle comprising an internal surface (2) and an external surface (4), the internal surface (2) not being visible when the mounting wheel (3) is mounted on the motor vehicle, and at least one fixing element (7) configured to attach the mounting wheel (3) to the motor vehicle. The fixing element (7) is arranged on the internal surface (2) of the mounting wheel (3) so that the fixing element (7) is not visible when the mounting wheel (3) is mounted on the motor vehicle.

The disclosed technology generally relates to a tire, and more particularly to a non-pneumatic tire that has handling performance similar to a pneumatic tire, supports the load of a vehicle and improves riding comfort by employing a parametric structure. In one aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that functions as a structural support between the rim and the tread, in which the spoke unit is formed by circularly arranging spokes. The spokes have a single closed-loop longitudinal cross-section circumscribed to the rim and around the center of the tire.

A structurally supported tire includes a ground contacting annular tread portion, an annular hoop structure for supporting a load on the tire, and a ply structure secured to a vehicle rim and the tread portion. The hoop structure is secured to a radially inner surface of the ply structure. The hoop structure includes a first double layer of steel cords and a second double layer of steels cords sandwiching a first layer of non-woven reinforcement, a second layer of non-woven reinforcement, and a single layer of steel cords.

The present invention discloses a rubber composition, a processing method thereof, and a foamed rubber product produced by the rubber composition and a production method thereof. The rubber composition comprises a rubber matrix and essential components, wherein, based on 100 parts by weight of the rubber matrix, the rubber matrix comprises a branched polyethylene with a content represented as A, in which 0<A100 parts; and an EPM and an EPDM with a total content represented as B, in which 0B<100 parts, and the essential components comprises 0.5-10 parts of a crosslinking agent, and 1.5-25 parts of a foaming agent. The rubber composition is useful in the production of sponge seal strip, foamed rubber compound of high expansion ratio, shock absorbing foamed rubber sheet, light-colored high-strength foamed sheet, foam-solid composite seal strip, and solid cycle tires internally filled with foamed elastomer. The branched polyethylene replaces a part or all of the ethylene-propylene rubber in the foaming rubber composition, which can increase the melt strength, the foamability and particularly the pre-foamability of the rubber composition, and make the rubber product has a lower compression set.

A method and apparatus for molding non-pneumatic wheels is provided. The exemplary method and apparatus allow for the use of the same molding system to manufacture wheels with different hub constructions. Different configurations of removable mold elements are utilized within the same molding system to provide wheels with different hub constructions.
