| 20110285195 | SET OF TWIN WHEELS - The present invention concerns a twin wheel set including twin wheel, intermediate ring and fixing means for coaxial mounting of the twin wheel set on a wheel of a vehicle, where twin wheel as well as vehicle wheel include a rim, preferably a steel rim with tyre. The new feature of the invention consist of the fixing means at least comprising an adjustable clamping ring, preferably a steel ring, for bearing on the rim periphery of the twin wheel at the side facing away from the vehicle wheel, preferably against at least one face on the inner peripheral area of the rim on a twin wheel. By using the outer side of the rim for contact with the adjustable clamping ring, there is achieved an independency of welding means thereon to which clamping devices are to be fixed on the twin wheel itself. By using a clamping ring which is not fixed to the twin wheel, a kind of universal clamping ring can be applied which possibly may be adapted to different sizes of twin wheels, and which therefore implies less need for keeping may different articles in stock at the producer. | 11-24-2011 |
| 20120074762 | MULTI-DIAMETER TIRE AND WHEEL ASSEMBLY FOR IMPROVED VEHICLE MILEAGE WITH PASSIVE TRANSFER BETWEEN TIRE DIAMETERS - The invention is a replacement wheel/tire assembly for a vehicle where the new assembly maximizes the balance between travel efficiency or mileage of the vehicle and traction requirements of the vehicle tires for safety and/or high performance. The invention yields an efficient driving mode on large diameter tires and a performance driving mode on small diameter tires, with passive and automatic transfer between these modes. Multi-diameter tire and wheel assembly comprises: at least one large diameter tire, at least one large diameter wheel, at least one small diameter tire, at least one small diameter wheel, and a wheel connection means. The number of wheels is equal to the number of tires in each multi-diameter tire and wheel assembly. Each large diameter tire is mounted and inflated onto one large diameter wheel and each small diameter tire is mounted and inflated onto one said small diameter wheel. Wheels are connected together in adjacent concentric fashion so that the centers of each said wheel and each said tire are aligned on the central longitudinal axis running down the center of said multi-diameter tire and wheel assembly. Multi-diameter tire and wheel assembly may be attached to a vehicle hub using existing studs located on the vehicle hub and existing lug nuts. | 03-29-2012 |
| 20120280560 | DUAL WHEEL AXLE ASSEMBLY - A dual wheel axle assembly includes an axle, a hub coupled to the axle, a rotor coupled to the hub, a surface of the axle assembly inboard of the hub, and an adapter. The adapter is coupled to the rotor or the hub. The adapter has an encoder ring portion positioned at a first distance from the surface of the axle assembly, wherein the first distance is substantially equal to a second distance from a corresponding surface of a single wheel axle assembly to an encoder ring portion of the single wheel axle assembly without the adapter. | 11-08-2012 |
| 20120292979 | DUAL WHEELS WITH COMMON HUB ADAPTER - A dual wheel assembly for a vehicle having a common hub adapter. The assembly includes an inner wheel having an inner rim; an outer wheel having an outer rim; and a hub portion having a central cylindrical portion disposed between first and second end face portions, wherein the inner rim is mounted to the first end portion, and the outer rim is mounted to the second end face portion. The assembly may further include radially spaced apart holes disposed on the central cylindrical portion, wherein the spaced apart holes have end openings on opposite sides thereof and first and second fasteners extending in opposite directions in an alternating arrangement from the first and second end portions of the hub portion. Each of the first fasteners extends through an end opening of a spaced apart hole and the inner rim, and each of the second fasteners extends through an end opening of a spaced apart hole and the outer rim. | 11-22-2012 |
| 20130140875 | Vehicle Wheel - A wheel for a vehicle, including a rim ( | 06-06-2013 |
| 20130162007 | INDEPENDENT DUAL WHEEL DIRECT DRIVE AXLES, BETWEEN THE DUALS GEAR BOX, AND INDEPENDENT SERVO DRIVE STEERING FOR BETWEEN THE DUAL DIRECT DRIVE SUSPENSIONS - A rear dual wheel direct drive axle assembly ( | 06-27-2013 |
| 20150042148 | DUAL TIRE SHIELD AND RUNFLAT - The Dual Tire Shield of the invention mounts between dual tires and helps to prevent debris from getting into the gap between dual tires and/or damaging the tires when it does so. In some embodiments it can also serve as a runflat for dual tires. Debris can become wedged between the sidewalls of dual tires that face each other, or “inner sidewalls” of such tires. The dual tire shield prevents debris from getting stuck between the inner sidewalls of the dual tires and thereby prevents flats caused by sidewall puncture or bead de-seating due to such debris. The device accomplishes this by: Blocking debris from entering the gap between duals and/or prevent debris from being wedged in the gap; keeping such debris from contact with one or both of the tires even if wedged therebetween; and/or ejecting debris from between the tires. Further, the dual tire shield may be made rigid enough and/or include rigid portions so as to act as a runflat in case a tire goes flat regardless of the reason. | 02-12-2015 |
