| 20090127921 | PROCESS FOR THE PRODUCTION OF CELLULAR POLYURETHANE (PUR) CASTING ELASTOMERS FROM STORAGE-STABLE 1,5-NAPHTHALENEDIISOCYANATE (NDI) PREPOLYMERS - The present invention relates to a process for the production of cellular polyurethane (PUR) casting elastomers and moulded articles based on 1,5-naphthalenediisocyanate (NDI)-prepolymers. | 05-21-2009 |
| 20090267404 | Spare tire assembly - A wheel on a vehicle having a flat tire may be protected by attaching a first semi-cylindrical shell having a first planar end to the wheel, and attaching a second semi-cylindrical shell to the first semi-cylindrical shell. The first semi-cylindrical shell and the second semi-cylindrical shell are secured together so as to form a cylindrical shell of diameter having a cylindrical wall which covers a tread surface of the flat tire. The first semi-cylindrical shell is attached to the wheel to cover a first portion of a tread surface of the flat tire; and, after attaching the first semi-cylindrical shell, the wheel is rotated. The first portion of the tread surface does not contact a ground surface prior to the rotation step, but does contact a ground surface through the first semi-cylindrical shell after the rotation step. A connector for connecting the semi-cylindrical shells to the wheel is also disclosed. | 10-29-2009 |
| 20130300184 | AUXILIARY WHEEL, UNASSISTED LIFTING JACK AND APPARATUS FOR UNLOCKING AND LOCKING SELF-LOCKING DEVICE OF AUXILIARY WHEEL - Disclosed is an auxiliary wheel comprising a wheel hub and a tire. The auxiliary wheel is fixedly mounted on a wheel of an automotive vehicle in a manner that the auxiliary wheel and the wheel have a common rotary axis. The auxiliary wheel may further comprise one or more locking components located on the wheel hub, and the locking component is used to fix the auxiliary wheel on the wheel hub of the wheel, so that the auxiliary wheel is driven by the wheel hub of the wheel. The present invention further relates to an unassisted lifting jack used when the auxiliary wheel is mounted. The unassisted lifting jack comprises a climbing block and a supporting block connected in a rotary way, the climbing block and the supporting block have a common supporting bottom, and the climbing block has a slope provided to the auxiliary wheel for climbing. | 11-14-2013 |

| 20080252135 | LOOSE TERRAIN TRACTION-ASSIST DEVICE FOR WHEELED ALL-TERRAIN AND UTILITY VEHICLES - In one embodiment, the present invention is a loose terrain traction assist device for wheeled vehicles, comprising 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 means 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. | 10-16-2008 |
| 301400200 | Auxiliary tire mounted to one side of main wheel | 1 |
| 20090015058 | ANTI-SINK RIM - The invention relates to a device which is used to free a vehicle that has become stuck in terrain or to reduce the risk of same, through the use of an additional tread which is disposed parallel to that of each wheel of the vehicle. The additional tread can take the form of an air chamber ( | 01-15-2009 |
| 301400300 | Safety emergency tire or rim | 3 |
| 20090051213 | SAFETY TIRE AND HOLLOW RING BODY - It is to solve problems in a safety tire in which hollow particles also referred to as the foamable compositions are filled in the hollow ring-shaped partition wall and to provide a safety tire having a partition wall structure capable of sufficiently developing the function of the hollow particles. | 02-26-2009 |
| 20120112520 | BURST-PROOF SAFETY TYRE OF VEHICLE - The present invention relates to an explosion-proof security tyre for vehicles. The tyre includes an outer tyre, a split rim, a L-shaped sealing ring, a combined support loop and a valve core. The combined support loop includes a plurality layers of support rings they are sleeved by layer on layer and fixed with the rim. The size of the tyre can increased by the combined support loop so as to furthest shorten the distance between the inner wall of the outer tyre and the outer wall of the combined support loop at a normal pressure of tyre. At the moment that the tyre is burst, the combined support loop can support the outer tyre quickly and effectively, and control the change of acting radius of the tyre in a minimum range so as to ensure the basic performance of the tyre and to prevent accidents caused by sudden control loss of running direction and avoid potential security risks. Moreover, the split rim is benefit for mounting the combined support loop by layering, and is easy to be assembled and disassembled so that the tyre can be maintained and replaced by normal tools. | 05-10-2012 |
| 20140246896 | ENHANCED STATIC RUNFLAT SYSTEM ASSEMBLY - An enhanced static runflat system is disclosed. According to an exemplary embodiment of the present invention, at least one predefined structural stopper provided on the outer peripheral surface of the cylindrical section of the wheel rim, whereby at least one predefined structural stopper secures, an inner circumference of the annular static runflat to an outer circumference of the wheel for arresting a movement of the static runflat over the wheel rim | 09-04-2014 |
