A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

A wheel having a longitudinal plane normal to an axis of rotation. The wheel has a rim with side surfaces on opposite sides of the longitudinal plane. A hub is concentrically disposed relative to the rim. Two unitary side elements are disposed on opposite sides of the longitudinal plane and are coupled to the rim and to end portions of the hub. Each of the unitary side elements has an annular sidewall, a flange portion, and a plurality of spokes that do not cross the longitudinal plane and that integrally interconnect the annular sidewall and the flange portion. An end portion of each spoke of the one side element is tied to the end portion of an aligned spoke of the other side element adjacent to the sidewall to restrict the tied end portions from moving away from each other.

The invention concerns an axle unit comprising a stub axle and a tube unit, wherein the stub axle at least in regions is configured rotationally symmetrically about a stub axis and has a channel which extends substantially parallel to the stub axis, wherein the tube unit is configured as a hollow body and extends substantially along a tube axis, wherein the tube unit has a recess running transversely to the tube axis, wherein a line element is provided which can be brought into fluid-tight connection with the channel and passed through the recess of the tube unit. A method for production of an axle unit is also given.

The present invention relates to an axle unit comprising an axle tube and an axle stub, wherein the axle stub is formed to be rotationally symmetrical with respect to a stub axis in some regions and has a channel which extends substantially parallel to the stub axis, wherein the axle stub has a first connection portion which has an engagement geometry for fluid-tight connection to the channel, wherein the axle tube is formed to be substantially rotationally symmetrical about a tube axis and wherein the axle tube and the axle stub are fixed on/to one another by way of a cross-member in such a way that the tube axis and the stub axis are spaced from one another.

A wheel assembly includes: a wheel set unit including a wheel bracket and a wheel; and a brake unit including a brake element disposed between the wheel bracket and the wheel, a threaded member sleeved movably on the brake element, and a screw extending threadably through the threaded member, extending through the brake element so as to prevent movement of the threaded member on the brake element, and pushable downwardly such that the brake unit moves downwardly to press resiliently against the wheel, so as to arrest rotation of the wheel. Only a single tool is needed to be accessed to a lower end of the screw so as to adjust a distance between the brake unit and the wheel.

A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange;

and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

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.

A jig for mounting a component on a structure is disclosed. The jig includes a frame having a base defining an elongated channel and adapted to be disposed substantially parallel to a surface. The jig also includes a support assembly for supporting the component to facilitate the mounting of the component on the structure. The support assembly extends vertically through the elongated channel and adapted to slide relative to the base along a length of the elongated channel.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

A tool for mounting a motor-vehicle wheel on a wheel hub includes a tubular body having a coupling portion arranged for coupling to the wheel hub, and a carrier portion for supporting the motor-vehicle wheel during a centering phase of the wheel on the hub. The tool has an inner tubular member and an outer tubular member rigidly connected to each other so as to be coaxial. At the coupling portion, the inner and outer tubular members are spaced apart so as to define a space arranged to receive an end portion of the wheel hub, in such a way that, in an operating condition, the end portion of the hub is interposed between the inner tubular member and the outer tubular member.
