A semi-trailer wheel restraint system having at least one bearing or swivel, or a combination of bearing(s) and swivel(s), and one or more cable sections and one or more hub cab attachments for receipt into one or more wheel assemblies and through a hollow core of the trailer's axle. During a wheel bearing failure, the wheel restraint system keeps the loose wheel assembly near the end of the axle by anchoring it to the opposite-end's hub cap, thereby preventing a run-away wheel assembly and providing an operator of the truck an opportunity to safely stop the rig.

An axle kit apparatus for increasing the mobility of foldable sawhorse stands while allowing the tires used to be customizable. The invention consists of an axle that connects all of the pieces together. It is mounted with two fasteners that pass through the axle. Two spindles thread into the axle to allow them to be removable. Two objects with threaded apertures lock the spindles in place as well as provide the necessary preload to the bearing races of any tire used. The invention allows for any size spindle and tires to be used as long as the spindle can thread into the axle.

A casing (43) of an in-wheel motor drive device (10) includes a tubular body first casing (43g) disposed on one side in an axial (O) direction and a tubular body second casing (43a) disposed on the other side in the axial direction. Each of the body first casing and the body second casing has an annular abutting surface (43j) so that the annular abutting surfaces of the body first casing and the body second casing abut on each other in the axial direction. A hub carrier (18) has at its tip end a connecting portion (82s) for rotatable connection to a vehicle body-side member (81). The connecting portion is disposed so as not to overlap the abutting surfaces in the axial direction and so as to overlap the body first casing or the body second casing in the axial direction.

A downhole device (15) comprising: a body (10) with a bore; at least one wheel (20) or other retained component; an engagement member (40) for engaging the wheel with the body. A retaining member (31) retains the engagement member (40) in place, the retaining member (31) extending along the body (10) and in the line of the main axis of the engagement member (40) so that it abuts. Embodiments allow for more convenient and more reliable retaining of wheels or other components in the device especially reducing the need for using threaded connections, which are prone to failure

A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

An L-shaped bushing assembly having a retainer pin sleeve and axle sleeve. An L-shaped retainer pin is fitted to the retainer pin sleeve and provides a handle piece that projects through the walls of the bushing assembly and wheel that is maneuverable to retract and release the retainer pin and wheel from a grooved axle. The L-shaped retainer pin and bias spring are alternatively mounted in single and multi-channel slots to facilitate retainer pin mounting and/or containment of the retainer pin at a storage position. The retainer pin sleeve slots and/or a transverse open slot facilitate cooperation of a wheel removal tool with the retainer pin(s).

In accordance with one aspect of the present disclosure, a wheel end apparatus for a vehicle is provided that includes a wheel hub assembly configured to be mounted to a spindle and a wheel hub of the wheel hub assembly. The wheel end apparatus includes a coil of wire and at least one magnet of the wheel hub assembly configured to move relative to one another with rotation of the wheel hub around the spindle. The wheel end apparatus includes a wheel end device operably coupled to the coil of wire to receive electrical power generated by relative movement of the coil of wire and the at least one magnet. Further, the wheel end apparatus includes communication circuitry operably coupled to the wheel end device and configured to wirelessly communicate wheel end device information with a wheel end monitoring device.
