Abstract:
Tire assemblies are disclosed. In one embodiment a tire insert assembly includes an elastomeric tire insert constructed to be received within a tire, the tire having sidewalls and a tread portion. An upper crown surface of the tire insert and a lower surface of the tire define an outer chamber and the tire insert defines an inner chamber. The tire insert may be configured to support a substantial portion of the sidewall of the tire when the inner chamber is inflated.

Abstract:
A tyre apparatus is provided, the apparatus including a tyre body for attachment to a wheel rim to define a first inflatable volume. An inner chamber defines a second inflatable volume which is located within the first inflatable volume of the tyre body. A first fluid communication path is provided between the first and second inflatable volumes and a second fluid communication path is provided between the first inflatable volume and the atmosphere. A first valve opens and closes the first fluid communication path, and a second valve opens and closes the second fluid communication path. The tensile strength and pressure-containing capacity of the material structure of the second inflatable volume is greater than that of the tyre first inflatable volume. A first fluid pressure within the first inflatable volume of the tyre body is optimisable by opening the first valve to allow pressure transfer from the second inflatable volume into the tyre body, and/or opening the second valve to allow pressure to vent from the tyre body to atmosphere. A vehicle wheel and active tyre pressure control system incorporating the tyre apparatus are also provided.
Abstract:
The present invention relates to an explosion-proof tire, comprising a safety airbag, trigger sensors and a safety switch, wherein the safety airbag is arranged between a tire and a hub; the hub is provided with grooves; trigger devices of the safety airbag are arranged in the grooves; one end of each trigger sensor sticks into the tire; and the other end thereof is connected with a trigger device. The safety switch is arranged on the valve stem of the tire; and positive and negative electrodes on the valve stem are each connected with a trigger device.The safety switch disclosed by the present invention ensures that the safety airbag will not be triggered accidentally, and when a vehicle tire bursts, the safety airbag provided can instantly provide enough support force to ensure traffic safety.
Abstract:
An object of the invention is to provide a tire tube which has excellent air impermeability and such excellent durability that the occurrence of cracks in the tube main body is prevented in a contact surface between the tube main body and an inner circumferential surface of the tire. The tire tube of the invention includes a tube main body having a multilayer structure in which at least one rubber layer and at least one thermoplastic resin layer made of a thermoplastic resin or a thermoplastic elastomer composition obtained by blending an elastomer in a thermoplastic resin are laminated together. In at least a region where the tube main body is in contact with the inner circumferential surface of the tire tread part, the rubber layer is placed as the outermost layer of the multilayer structure, and the thermoplastic resin layer is placed inside the outermost layer.
Abstract:
A self-locking device having continuous locking positions comprises bases (21, 31), self-locking components (22, 32), first locking blocks (23, 33, 33′) and second locking blocks (23a, 33a, 33a′). Inner walls of the bases (21, 31) comprise first frictional contact surfaces (21W, 31W) and fourth frictional contact surfaces (21M, 31M). The self-locking components (22, 32) have second frictional contact surfaces (22M, 32M) and third frictional contact surfaces (22W, 32W), and are at least partially located in the bases (21, 31), so that the second frictional contact surfaces (22M, 32M) face the first frictional contact surfaces (21W, 31W), and the third frictional contact surfaces (22W, 32W) face the fourth frictional contact surfaces (21M, 31M). The first locking blocks (23, 33, 33′) are disposed between the first frictional contact surfaces (21W, 31W) and the second frictional contact surfaces (22M, 32M), and contact the first frictional contact surfaces (21W, 31W) and the second frictional contact surfaces (22M, 32M). The second locking blocks (23a, 33a, 33a′) are disposed between the third frictional contact surfaces (22W, 32W) and the fourth frictional contact surfaces (21M, 31M), and contact the third frictional contact surfaces (22W, 32W) and the fourth frictional contact surfaces (21M, 31M). The first locking blocks (23, 33, 33′) and the second locking blocks (23a, 33a, 33a′) are in such a structure that the self-locking components (22, 32) are capable of moving along a first direction (F1) relative to the self-locking bases (21, 31) under the effect of an external force, and are locked in a second direction (F2) opposite to the first direction (F1). In this way, the self-locking components (22, 32) can be locked at any one of the continuous locking positions. Also disclosed is a tool (7A-7C) for locking and unlocking the self-locking device. The self-locking device is capable of implementing fast locking and unlocking, which is convenient to use.

Abstract:
It is an object of the present invention to provide a useful inner structural supporter type run flat tire having enough structural strength for controlling the steering wheel to some extent when the tire goes flat and having easy structure for installing to the rim wheel. A wheel 10 has a flange 11 with a bead part of a tubeless tire fitted thereto and a container 12 having a diameter smaller than that of the flange 11, and comprises a rim valve for adjusting the air pressure of the tubeless tire, and a second rim valve for adjusting air pressure in an inner tire 20. The inner tire 20 is stored in the container 12. While the inner tire 20 is stored in the container 12, the tubeless tire 30 is fitted to the flange of the tire wheel 10, air is fed into the inner tire 20 via the second rim valve until the air pressure reaches a predetermined value, so the inner tire 20 is inflated inside the tubeless tire 30, and an inner tire is provided as the inner tire in the outer tubeless tire space.
Abstract:
The present invention relates to a vehicle wheel having inner and outer tires which can allow a vehicle to be moved to a place of safety or a near service station by forming the inner and outer tires and by maintaining balance and steering control of the vehicle by means of the inner tire positioned inside the outer tire even when the outer tire blows out or gets torn. The vehicle wheel comprises a rim connected with an axle of a vehicle, an outer tire having a large diameter mounted on an outer circumferential surface of the rim and an inner tire having a small diameter positioned inside the outer tire and mounted on the rim, wherein a first air compression chamber formed between the outer circumferential surface of the rim and the inner tire and a second air compression chamber formed between the outer and inner tires.
