Abstract:
A vehicle wheel including a wheel rim, a pneumatic tire comprising a tread and first and second side walls, wherein each of the first and second side walls comprise a bead having a bead core, an emergency running support body including an emergency running surface and first and second axial outer wall sections, the emergency running support body further comprising the shell-shaped ring body adapted to be disposed within the tire and to support the tire in case of damage, a first ring-shaped supporting element, and a second ring-shaped supporting element, whereby the first axial outer wall section is supported on the wheel rim via the first ring-shaped supporting element and the second axial outer wall section is supported on the wheel rim via the second ring-shaped supporting element, wherein the shell-shaped ring body is one of removably connected and removably attached to one of the first ring-shaped support element and the second ring-shaped support element, and wherein one of the first ring-shaped supporting element and the second ring-shaped supporting elements is one of elastically deformable and swivelable in an axial direction.
Abstract:
The tire for a vehicle comprises a main body of the tire made from a rubber composite material and a rim to form a toroidal space therein, accommodates a toroidal pneumatic tube expandable due to its elasticity in the space for liquid, and the pneumatic tube has a smaller volume than that of a form obtained by depressing the space for liquid to a desired level by a road surface at the point of time when the tube is filled with air at a specified pressure required for supporting a load imposed on the tire, and the space for liquid in the depressed form which is outside of the tube is filled with liquid so that a desired ground contact area of the tire can be obtained under the load.
Abstract:
A pneumatic tire includes an inflatable tire tube having a plurality of inflatable cell units arranged in an annular formation. A check valve is provided in a cell inlet opening of each cell unit. A control chamber is disposed adjacent to each cell unit and includes a diaphragm member provided therein so as to partition the control chamber into first and second fluid compartments. The first and second fluid compartments of the control chambers are respectively connected to and communicated with those of adjacent control chambers. Each check valve has a first portion extending into one of the cell units and a second portion extending into the first fluid compartment of one of the control chambers. A first tire valve is provided to charge air into and to release air from the second fluid compartment of each of the control chambers so as to move the respective diaphragm member to correspondingly open and close the check valves. A second tire valve is provided to charge air into and to release air from the first fluid compartment of each of the control chambers so as to inflate or deflate the cell units when the respective check valves are open.
Abstract:
A safety tube assembly for a pneumatic tire, the assembly including a plurality of balloons being contiguously disposed on the underside of a tread portion of the tire and an annular primary tube accommodated within the circumference of the balloons whereby each of the small balloons becomes an independent chamber interposed between the primary tube and the underside of the tread portion. Another feature of the invention is the provision of a puncture-resistant band surrounding the small balloons for dual protection against puncture of the pneumatic tire.
