A lug nut loosening assembly includes a coupler that has a well therein for insertably receiving a free end of a lug wrench. The coupler has an axle aperture therein and an axle is insertable through the axle aperture. A pair of wheels is each of the wheels is positionable on the axle when the axle is inserted through the axle aperture wherein each of the wheels is configured to rest on a support surface upon which the vehicle is parked. each of the wheels rolling along the support surface when the vehicle is rolled rearwardly and when the lug wrench is positioned on the lug nut and is inserted into the sleeve wherein the pair of wheels is configured to transfer the rearward motion of the vehicle into counter-clockwise rotation of the lug wrench for breaking free the lug nut.

A wheel drive unit for a vehicle includes a connecting member separably coupled to a constant velocity joint, a hub housing accommodating the constant velocity joint, and a hub cap to seal the hub housing. In particular, a fixing groove is formed around a first end of the constant velocity joint, and the connecting member is fitted in the fixing groove in a ring shape. When the hub cap is separated from the hub housing, the connecting member can be easily disassembled from the constant velocity joint such that inner components of the wheel drive unit can be easily replaced and repaired.

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.

A hub removal assembly for disengaging a hub stuck to an axle. The hub removal assembly includes a rectangular bar having a central sinkhole. An elongated lead screw having a proximal end and a distal end. The proximal end of the lead screw is transversely screwed into the central sinkhole. The distal end of the elongated lead screw is configured as a head that can be turned by a pneumatic tool.

A wheel assembly includes a rim having a primary tire bead retention ridge; a plurality of secondary bead retention members; and a plurality of sealing members. The plurality of secondary bead retention members are removably coupleable to receptacles of the rim such that a portion of each secondary bead retention member extends into a pressurized portion of the wheel, is positioned behind a tire bead seat, and extends radially beyond the primary tire bead retention ridge.

A lug nut loosening assembly includes a coupler that has a well therein for insertably receiving a free end of a lug wrench. The coupler has an axle aperture therein and an axle is insertable through the axle aperture. A pair of wheels is each of the wheels is positionable on the axle when the axle is inserted through the axle aperture wherein each of the wheels is configured to rest on a support surface upon which the vehicle is parked. each of the wheels rolling along the support surface when the vehicle is rolled rearwardly and when the lug wrench is positioned on the lug nut and is inserted into the sleeve wherein the pair of wheels is configured to transfer the rearward motion of the vehicle into counter-clockwise rotation of the lug wrench for breaking free the lug nut.

The ultralight two track train that does not derail, made up of one or more ultralight wagons and aerodynamic, oval or semi-oval transverse profiles, characterized in that the wagons carry vertical or inclined wheels or pulley wheels in their lower area and supported by the chassis of the wagons, which rest and roll on a pair of vertical or inclined rails, the channels of the pulley wheels are supported and held on the head of circular, semicircular or semi-oval section of the rails, the heads of the rails being trapped with the pulley wheels, adding pairs of wheels that use a common axis, the rails are coupled and fixed tongue and groove to the sleepers or to some monolithic structures or channels, the sleepers are fixed using the track system on concrete slab, using electrical supply means, propellant means and reducing means of the front, rear and lateral resistance of the wagons, adding wheels with permanent magnets or with electromagnets that are attached, or run close and attracted by the rails.

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 wheel assembly has a wheel with a hub. A rotation surface disposed in the hub has a bore. A sleeve insertable in the bore of the rotation surface has an outer surface with a circumferential groove and first and second opposite axial ends. The first axial end has a shoulder extending radially outward. A resilient ring disposed in the circumferential groove is compressible to a compression diameter sufficient to enable the sleeve to be inserted in the bore of the rotation surface. The resilient ring is expandable to an expansion diameter greater than the inner surface diameter of the bore of the rotation surface when unconstrained. The circumferential groove is spaced from the shoulder at a distance sufficient to enable the resilient ring to expand to the expansion diameter when the sleeve is inserted in the bore of the rotation surface and the shoulder is adjacent the rotation surface.

This application discloses an apparatus 100 for use with an electrically, hydraulically and/or pneumatically driven torque tool for tightening or loosening inaccessible threaded fasteners including a drive extension assembly 110, a reaction assembly 120 and a socket assembly 130. Advantageously the present invention uses an external reaction member which holds on to two (2) or four (4) adjacent studs while turning a fastener with an extended drive ball and socket joint connection. It more efficiently distributes/reduces the side loads and system strains from the reaction forces on the bolts by bringing the reaction point much closer to the fastener being turned. It allows for a plurality of fastener approach angles and is adaptable to a plurality of fastener obstructions. It's relatively lightweight, easy to maneuver from fastener to fastener and overall user friendly.
