In a pneumatic, tired wheel having a tubeless tire mounted on the rim of the wheel, the improvement comprising a toroidal support device to enable the tired wheel to travel in a flat state. The support device comprises an inflatable, toroidal, inner tube located on the rim for elastically clamping the tire beads against the rim flanges, said tube radially extending from the well of the rim to or slightly beyond the radially outer edges of the rim flanges, and a toroidal support element whose radially internal, circumferential wall section is impervious to puncture and lies adjacent the radially external, circumferential area of the inner tube, and wherein the outer surface area of the support element is spaced from the inner surface area of the tire when the tire is in its inflated state so that under normal travel conditions the support element does not contact the inner surface area of the tire. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way.

In accordance with embodiments of the present disclosure an inner tube comprises an encasing configured to hold air. The encasing comprises a reinforcing structure configured such that, as the encasing is inflated, an overall major diameter of the inner tube is reduced. The inner tube also comprises an inflation valve coupled to the encasing and configured to allow inflation of the encasing. Further, the inner tube comprises a pressure valve coupled to the encasing. The pressure valve is configured to be biased closed and allow air to leave the encasing when a differential pressure between inside of the encasing and outside of the encasing reaches a threshold pressure level. In the same or alternative embodiments, the encasing also comprises a reinforcing structure configured such that, as the encasing is inflated, an overall major diameter of inner tube is reduced.
摘要:
A tube-type tire to be mounted on the rim of a (e.g., spoke-type) wheel such as that commonly used by a bicycle or a motorcycle, whereby the tube-type tire will operate without a conventional inner tube and as if it were tubeless. The tire includes a main tire section that is seated upon the generally flat shelf of the rim and a pneumatic sealing ring having an inner tube that is seated upon the beadwell of the rim. An air chamber of the inner tube of the sealing ring is inflated to a greater pressure than an air chamber of the main tire section so as to isolate the air chamber of the main tire section from the rim and force the main tire section against the vertical lip of the rim. The sealing ring also has an outer inflatable liner that is located in surrounding engagement with the inner tube to separate the inner tube from the air chamber of the main tire section. The outer liner has one or more O-ring seals projecting outwardly from the side walls thereof and a centering lip projecting downwardly from the side walls. The O-ring seals are moved into sealing engagement with the inside of the main tire section when the air chamber of the inner tube is inflated and the liner is expanded. The centering lips of the liner are seated upon the beadwell of the rim to cause the liner to be automatically centered over the inner tube.

Tire assembly for a bicycle rim, including a wheel tire with a tread surface and two tire beads, an inner tire disposed within the wheel tire, a tube disposed within the inner tire, and a valve arrangement for filling the tube and an intermediate space between the rim and the wheel tire with different air pressures. The inner tire in the filled and mounted condition bears on the tire beads of the wheel tire and presses the beads against the rim. The inner tire has a first through opening which in the mounted condition communicates with the intermediate space, and an insert part disposed between the rim and the tube and between the tube and the inner tire. The insert part forms an air duct between the rim and the tube and between the tube and the inner tire up to the through opening in the inner tire.
摘要:
The invention relates to a tire assembly for a bicycle rim, comprising a wheel tire with a tread surface and two tire beads which in the mounted condition bear on the interior side of the rim edges, an inner tire which in the mounted condition is disposed within the wheel tire, a tube which in the mounted condition is disposed within the inner tire, valve means for filling with different air pressures, on the one hand side, the tube and, on the other hand side, an intermediate space between the rim and the wheel tire, wherein the inner tire in the filled and mounted condition bears on the tire beads of the wheel tire at least in sections and presses said beads against the rim, wherein the inner tire is provided with a first through opening in its wall, wherein the first through opening in the mounted condition is in communication with the intermediate space between the rim and the wheel tire, and wherein an insert part is provided which in the mounted condition is disposed between the rim and the tube, and between the tube and the inner tire, and which at least in sections forms an air duct between the rim and the tube, and between the tube and the inner tire up to the through opening in the inner tire.
