Abstract: The vehicle wheel rim with integral spare tire includes a main wheel and an integral spare tire. The main wheel includes a main rim well, an inner and outer flange, and a center disc. A main tire may be mounted onto the main wheel and the main wheel may be bolted onto a hub on an axle of a vehicle. The integral spare tire includes a safety rim well, safely rim, and safety tire with the safety tire mounted on the safety rim. The integral spare tire is coupled to the inside of the main wheel. The dimensions of the main wheel, main tire, and integral spare tire are such that when the main tire is inflated the integral spare tire does not touch the road surface. However if the main tire goes flat the integral spare tire will touch the road surface and will support the vehicle.

Abstract: This invention relates to a universal brake system (UBS) that combines features from an adjustable wheel traction system (WTS) and an improved anti-lock brake (ABS) system. The WTS provides a plurality of extendable and retractable spikes contained in a wheel assembly or wheel adapter to increase traction (friction) between a vehicle's wheel and its supporting surface. To further improve wheel traction each wheel spike has different types of changeable heads for different types of terrain and road surfaces. When operating in dry road mode, the UBS operates as an anti-lock braking system except the spikes can operate during emergency braking to provide additional traction between the tire and wheel support surface.

Abstract: A loose terrain traction assist device for wheeled vehicles includes a generally frusto-conical structure having a proximal portion with a diameter smaller than an overall diameter of a tire of a vehicle, a distal portion that extends outwardly from the wheel, and an outer surface defined between the proximal portion and the distal portion. The traction assist device also includes an attachment arrangement for releasably coupling the frusto-conical structure to a wheel assembly of the vehicle, such that at least part of the frusto-conical structure is adapted to engage with terrain during operation of the vehicle in loose terrain and to not engage with terrain during operation of the vehicle on normal terrain.

Abstract: Device used to free a vehicle that is stuck in terrain or to reduce such risk through the use of an additional tread disposed parallel to each wheel of the vehicle. The additional tread can be an air chamber (2 or 10a and 10b) covered or not with a tire (11) or a band comprising different coupling profiles (13, 14 or 15). The tread is mounted onto an anti-sink rim comprising a conical profile (1.2) and a flange (1.1) centered in and applied against the outer side of the wheel disc by special bolts (6) inserted in respective openings in the flange and rim. The diameter of the system is smaller than that of the wheel to facilitate mounting and to avoid interference with the vehicle body. The conical shape of the rim profile (1.2) lends stiffness and enables the rims to be stacked for reduced storage volume in trunk.

Abstract: For fastening an auxiliary wheel to the wheel of a vehicle, bolts are fixed to the auxiliary wheel, which bolts are aligned substantially parallel to the wheel axle of the auxiliary wheel. Each of the bolts has a head which can be inserted into slot-shaped recesses provided on the wheel of the vehicle and can be pushed into the slot-shaped recesses. The head of the bolts is hereby held in the slot-shaped recesses. The auxiliary wheel is locked in this position through locking apparatus. A simple mounting and dismounting of an auxiliary wheel to the wheel of a vehicle is thereby obtained.

Abstract: Novel wheel assemblies for use in track drive systems in a tracked vehicle, in support of improving uniformity of pressure distribution across the width of the track, between the track and the underlying ground surface, where track installed on the vehicle is wider than the wheel bodies which are supplied as original equipment with the tracked vehicle. Such improved uniformity of pressure is achieved by adding, to the wheels of such tracked vehicle, auxiliary wheel bodies which extend the widths of the wheels to widths more reflective of the width of the track being used in such vehicle. In cases where different track widths are sequentially employed on a given vehicle, auxiliary wheel assemblies of respective different widths can be sequentially mounted, removed, and the like to reflect the widths of the tracks being employed.

Abstract: A dual wheel assembly is formed by an inner wheel (10) and an outer wheel (30) coaxially mounted on a common hub (11). The inner wheel (10) has an inner tire (13) mounted on an inner wheel rim (12). The outer wheel (30) has an outer tire (13A) mounted on an outer wheel rim (32). The wheels (13, 13A) are of the same size, but the diameter of the outer wheel rim (32) is smaller than the inner wheel rim (12), to permit the inner tire (13) to pass over the outer wheel rim (32), thereby enabling the inner tire (13) to be removed without first removing the outer wheel rim (32). Removable bead seats (37, 40) are provided between the outer wheel rim (32) and its tire (13A). These bead seats are thicker than the corresponding bead seat(s) on the inner wheel (10) to compensate for the reduced diameter of the outer wheel rim.

Abstract: A roller is designed for adaptation into a blasthole drill and is specifically designed for use in conjunction with a rotary carriage to allow the carriage to move up and down a blasthole drill mast as needed. The roller is made of a substantially non-deformable material combined with a deformable material. Under light loads, the deformable material contacts and supports the load to provide enhanced operation of the roller. Under heavy loads, the deformable material advantageously deforms to a point which allows the substantially non-deformable material and deformable material to contact and cooperatively support the load.

Abstract: The safety wheel assembly uses spacer mounting nuts to allow the mounting of a spare or second wheel and tire on an existing motor vehicle wheel mount assembly. The primary wheel and tire of a vehicle are normally mounted using lug or mounting bolts. These bolts are then used to secure the primary tire with the spacer mounting nut which thereby provides for mounting the spare wheel and tire outwardly of the primary wheel relative to the vehicle. The two tires and wheels are spaced such as not to contact one to the other. The spare tire is a smaller diameter than the primary wheel. For example the standard size spare tire of solid rubber may be mounted in such a position as such spare tires are of a smaller diameter. The spare tire may also have protruding elements on the tire surface to aid in travel under snow conditions.
