A impact resistant rim is configured to soften or minimize an impact, thereby reducing the risk of pinching or otherwise flattening the tire and/or damaging the rim. This impact resistant rim further reduces the effects of an impact by maintaining the integrity of the rim during and following the impact. In this rim design, a shock absorbing cord is inlaid, molded, an/or otherwise embedded inside opposing leading edges of the rim. The shock absorbing cord is designed to elastically and/or plastically deform during an impact.

The present invention discloses a burst-resistant tire with tubular embedded open-structure, comprising an outer ring and an inner ring. The outer ring is divided into a left outer ring and a right outer ring symmetrically arranged through a radial plane of a tire center. The left outer ring and the inner ring are provided with a left rim ring, a right rim ring is arranged between the right outer ring and the inner ring, and the left rim ring and the right rim ring are connected at the radial plane of the tire center. When touching the ground, a rim forms a buffer structure via left and right parts using a joint point between the rim and the outer ring as a center, thereby rapidly dispersing stress, avoiding force concentrating on a single point, causing overloading.

An aircraft wheel and brake system includes a wheel assembly mounted on an axle portion of landing gear of an aircraft. The aircraft wheel and brake assembly may include a brake assembly installed within an interior space defined by the axle portion of the landing gear. The brake assembly may occupy substantially all of an interior installation volume defined by the axle portion, thus increasing a brake mass that can be accommodated by a given axle/wheel size/configuration. The brake assembly may be accessible at an open outboard side of the axle portion, allowing for removal and replacement of the brake assembly without removal of the wheel assembly from the axle portion of the landing gear and/or lifting of the aircraft to facilitate removal of the wheel assembly. The wheel assembly may include a tire mounted on a rim assembly including multiple rim portions coupled by an interior fastening ring.

A spare wheel assembly comprising a tire and a rim to which the tire is attached is disclosed. The rim includes a center mounting plate having a center bore, inner and outer opposed flanges, and a disk between the center bore and the flanges. The disk includes a pair of elongated, curved slots formed on opposite sides of the center bore. Each of the slots is an ergonomically-formed hand hold for receiving fingers of an operator's hand. The inner and outer opposed flanges of the rim define perimeters of the rim between which the tire is held. The curved slots are concentric with respect to the perimeter of the outer flange and with respect to the center bore. A centerline is formed radially through the assembly. The disk is positioned on one side of the centerline and the mounting plate is positioned on the other side of the centerline.

A structurally supported tire includes a ground contacting annular tread portion, an annular hoop structure for supporting a load on the tire, a means for attachment to a vehicle rim, and a ply structure secured to a first axial limit and extending radially outward and between the hoop structure and the tread portion and further extending radially inward from between the hoop structure and tread portion to a second axial limit. The ply structure is secured to both the first axial limit and the second axial limit. The tread portion is secured to a radially outer surface of the ply structure. The hoop structure is secured to a radially inner surface of the ply structure.

A piezoelectric energy harvesting system for converting mechanical energy of a tire of a vehicle to electrical energy includes sets of piezoelectric beam assemblies, a tire electrical jack, a conductive bearing, and an electrical storage unit. The sets of piezoelectric beam assemblies are embedded in multiple layers of the tire of the vehicle and electrically connected in a parallel configuration. Each of the sets of the piezoelectric beam assemblies are electrically connected in a series configuration for converting mechanical strains into electrical energy. The tire electrical jack is mounted on a rim of the tire and receives the electrical energy generated by the sets of piezoelectric beam assemblies via output terminals. The conductive bearing transmits the electrical energy received by the tire electrical jack to the electrical storage unit, which filters, rectifies, adapts and stores the transmitted electrical energy for powering components of the vehicle.

An auxiliary wheel including a wheel hub and a tire, the wheel hub includes an outer wheel hub and an inner wheel hub and the tire is mounted on the outer wall of the outer wheel hub. The outer wheel hub and the inner wheel hub are detachably connected through a first connection component. When the first connection component unlocks the connection between the outer wheel hub and the inner wheel hub, relative rotation is generated between the outer wheel hub and the inner wheel hub with bearings disposed between the inner wheel hub and the outer wheel hub to reduce friction. Friction is reduced between the outer and inner wheels, thereby increasing the upper limit of the auxiliary wheel rotation speed. A nut and bolt arrangement is disposed in the nut groove to firmly fix the ring on the outer wall of the outer wheel.
