A wheel hub for a utility vehicle includes a brake element abutment surface against which a brake element bears in an installed state, and a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and/or a receiving region for a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state.

A wheel assembly and method of assembling the same for use with an airless or non-pneumatic tyre. The assembly includes a rim member and at least one locking or retaining member. The rim member includes a first portion at least part of which is adapted to be attached to an axle in use, and at least part of the locking member is configured to detachably attach to at least part of the first portion of the rim member. Attachment to the rim member assists in retaining the tyre in position on rim member and/or the wheel assembly in use.

A wheel assembly includes a rigid wheel and an airless flexible tire with certain performance characteristics of a pneumatic tire. The rigid wheel includes a central portion and a plurality of circumferentially spaced mounting elements removably attached to a radially outer margin of the central portion. The tire is mounted on the wheel and engages the mounting elements such that portions of the tire not engaging the mounting elements are separated radially from the wheel by a space. The tire is configured such that portions of the tire not engaging the mounting elements flex inwardly toward the wheel when subject to ground engaging pressure, thereby minimizing ground penetration and soil disruption. The tire may include one or more tension elements embedded in the tire to increase the tire's strength and resilience.

A maintenance assembly for a wheel assembly of an amusement ride vehicle includes a foundational body, a wheel engagement section extending a first distance from the foundational body, and a datum section including a protrusion extending a second distance from the foundational body. The wheel engagement section is configured to contact a wheel surface of the wheel assembly, and the datum section is configured to contact a pad of the wheel assembly. Additionally, the wheel engagement section is rigidly positioned with respect to the datum section, and the second distance is greater than the first distance, such that the maintenance assembly provides a fixed distance between a surface of the datum section configured to contact the pad and a surface of the wheel engagement section configured to contact the wheel surface.

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that is fit and connected with rim and a nut cap bushing that is fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The hole wall surrounding the mounting hole is provided with a second tapered section. The mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together.

An axle extension member configured for attachment to an axle flange of a truck may be used to modify the truck from a standard track configuration to a wider track configuration to accommodate super single wheels. Methods for adjusting track width of a truck axle are also provided. The axle extension member includes an annular spacer portion and a spindle portion configured to receive an extended length axle shaft therethrough. The annular spacer portion is configured to abut and attach to an outboard face of the axle flange. At least one attachment feature is configured for attaching a disc brake assembly to the axle extension member.
