Implementations disclosed and claimed herein provide systems and methods for identifying and mitigating lug nut loosening. In one implementation, an indicator body of an indicator has a top surface connecting a front surface and a back surface. A first side of the indicator body is disposed opposite a second side of the indicator body. A receiver extends from the top surface into an interior of the indicator body. The receiver is configured to form a translational relationship of the lug nut with the indicator through a mating fit of the lug nut within the receiver. The translational relationship generates a corresponding rotation of the indicator body in response to a rotation of the lug nut. The corresponding rotation of the indicator body provides an indication that the lug nut is loose.

Systems, methods, tangible non-transitory computer-readable media, and devices associated with the operation of a vehicle are provided. For example, a wheel unit system can receive vehicle data including information associated with states of a vehicle. Further, the vehicle can include wheel wells associated with wheel units that are configured to generate indications associated with the states of the vehicle. The wheel unit system can also determine indications to generate on the wheel units based at least in part on the vehicle data. Furthermore, the wheel unit system can generate the indications on the wheel units. The indications can, for example, include visual indications or auditory indications.

A training wheel assembly includes an assembly frame and a training wheel rotatably attached to the assembly frame. The training wheel has a wheel axle extending therefrom and defining an axis about which the training wheel rotates, and an annular hub concentric with the wheel axle and rotationally fixed therewith. A plurality of successive ratcheted teeth facing the assembly frame form a circumferential inner edge of the wheel. An elastically deflectable tongue is attached to the assembly frame and is selectively extendible into a rotational path of motion of the ratcheted teeth, whereby upon rotation of the training wheel with respect to the assembly frame about the axis, contact of the elastically deflectable tongue with successive teeth of the plurality of ratcheted teeth generates an audible sound indicating that the training wheel is rotating.

An anti-rolling wheel includes: a ring-shaped main wheel; an inner frame positioned inside the main wheel, wherein the inner frame comprising at least two auxiliary wheels that come into contact with an inner surface of the main wheel and rotate when the main wheel is driven; and a sliding block provided to be movable under the guide of the inner frame.

A tire support rim for track roller associated with a flange is provided with a circular tire (2), and a support rim (1) for an annular track roller producing a flange. The rim (1) defines a peripheral edge intended to bear a tire, a medial edge in contact with the medial portion of the roller, and two opposite faces producing, on the one hand, an open face and, on the other hand, a bearing face positioned against the surface of the flange of the roller. The rim (1) incorporates a cooling device having at least one circulation duct for air passing through the thickness of the rim from an orifice (51) of the open face such that the duct has a portion at the medial edge and a portion positioned radially on the bearing face between the medial and peripheral edges.

Adapter for a rolling assembly, of axis of rotation X-X′, comprising a tire (2), a rim (3), and an adapter (100), said adapter comprising an axially inner end (10), an axially outer end (11) and a body (12), wherein said axially outer end comprises an outer reinforcing element (15) which is a structure substantially of revolution about the axis X-X′ comprising a plurality of windings of at least one wire that are arranged axially beside one another over several layers radially superposed on one another. The section of the outer reinforcement (15) has a ratio of moments of inertia Ix/Iy of greater than 1.3 for an axial width of between 6 and 9 mm, where Ix is the moment of inertia around a first axis passing through its centre of gravity and parallel to the axis of rotation X-X′, and Iy is the moment of inertia around a second axis passing through its centre of gravity and perpendicular to the first axis.

A non-pneumatic tire includes a wheel portion, a tread ring portion, a plurality of flexible spokes extending between and attached to the wheel portion and the tread ring portion, and plurality of bump stops positioned between the wheel portion and the tread ring portion. The bumps stops are configured to limit deformation and/or compressive strain of the plurality of flexible spokes. The plurality of bump stops includes a plurality of tower bump stops, a plurality of triangular-shaped bump stops, and/or a plurality of roof-top shaped bump stops.

An object to provide a brake device for a caster that has a simple structure, provides reliable braking, has no risk of damaging the circumferential surface of a roller, and has high durability. The brake device for a caster includes: a plurality of projecting parts formed concentrically at regular intervals on opposite side-surfaces of a roller in a direction in parallel with the axis, and levers set across the roller at both side-panels of a fork so as to be opposed to the projecting parts, and a claw formed at a tip of each of the levers so as to be opposed to the projecting parts, wherein the levers are operated so that the claw is engaged with a concave part formed between the projecting parts, thereby locking rotation of the roller.

A wheel lug nut locking attachment, lug nut position locator device, or lug nut locking device is provided, wherein the attachment or devices include a thermochromic material which provides an indication of excess heat generation in the wheel assembly of a tractor trailer. A warning system to alert an operator of the present of excess heat in the wheel assembly is provided. In a preferred embodiment, the device also acts to lock a wheel lug nut to an adjacent wheel lug nut, so as to prevent or reduce rotation of the wheel lug nut. A plurality of thermochromic lug nut locking devices can be fitted to a single wheel so that all of the lug nuts are operatively locked to an adjacent lug nut. The resulting locking system can be rapidly installed on each lug nut on all wheels, so as to provide improved vehicle safety aspects.

A wheel knuckle for supporting a wheel of a vehicle includes an upper member for connection to a vehicle suspension system, and a hub for supporting a bearing assembly. A displacement control member is provided for promoting displacement of the upper member towards a front of the vehicle in the event of a frontal collision. The displacement control member comprises a distal end for positioning proximal to a rim of the wheel. The distal end of the control member is disposed at a vertical height which is lower than a rotational axis of the wheel.
