Abstract:
A vehicle wheel with a one-piece rim and tubeless pneumatic tire comprises an emergency rolling surface on a radially exterior shell of the rim, an elastic bead, and a one-piece toroidal chamber at each axial front end of the rim. Each chamber includes a closed radially interior chamber wall, a closed radially exterior chamber wall, a closed axially interior chamber wall, and an axially exterior chamber wall axially closed in a radially exterior area defining a radially inwardly directed flange and open in a radially interior area. A filler ring is radially secured in each chamber on the radially interior chamber wall. Each side wall of the tire extends inwardly from the axially exterior wall through the opening, and the head is embedded in the chamber such that the bead lies across the axial extent of the filler ring, the head and the filler ring completely filling the chamber.
Abstract:
A pneumatic tire for a vehicular tire and wheel assembly that includes a rigid wheel rim, which is provided with essentially radially inwardly extending rim flanges, rim seating surfaces disposed on the radially inner side of the rim ring and inclined in the transverse direction, and a recessed mounting bed for each tire bead, and that also includes a pneumatic tire of elastomeric material, with bead seating surfaces of the tire beads being disposed adjacent to the rim flanges on the rim seating surfaces, and with the carcass of the tire being anchored in the beads by being looped about pressure-resistant bead cores. In order despite manufacturing-related tolerance differences of the rims and tires to obtain an improved bead seating, each bead is provided with recesses disposed therein in such a way that when the tire is mounted on the rim and inflated to the operating pressure, a base portion of the bead that rests against the rim seating surface exerts thereon a compression pressure in the range of from 8 to 56%.
Abstract:
A wheel rim includes a collar and a seat separate from the collar. Betweenhe collar and a bead, there is provided, axially in the mounting plane, a clearance which facilitates the mounting of the bead on the inside of the edges of the wheel rim. Then, the seat is inserted which eliminates the mounting clearance and keep the bead centered in relation to the wheel rim.
Abstract:
A vehicle wheel and pneumatic tire assembly having a counter-weight. The assembly includes a rigid rim having essentially radially inwardly extending rim flanges, a pneumatic vehicle tire, the beads of which are mounted on the radially inner side of the rim next to the rim flanges, and respective cover rings that occupy any space disposed axially inwardly of each tire bead. In order after a counter-weight has been mounted to prevent dirt or water from penetrating between the tire bead and the cover ring, a mounting element, which serves to support the counter-weight, extends into a slot of the cover ring. The base of this slot is disposed within the cover ring.
Abstract:
The free end regions of the carcass of the tire form bead regions by extending these free end regions around a bead core. Each bead region of the tire carcass is seated on a related seat or seat surface formed at the tire rim. A first end region of a bead ring anchors the associated bead region on the associated seat and a second end region of this bead ring is locked in a locking groove formed at the related edge region of the tire rim. The bead ring is preferably made of spring steel and may be provided with cuts or cutouts in its second end region to facilitate the mounting thereof at the tire rim. The first end region of the bead ring may be vulcanized into or otherwise connected with the tire carcass. The seat may be formed at the inner circumferential surface or at the outer circumferential surface of the tire rim.
Abstract:
A covering ring for a vehicle wheel. The bead seating surfaces of a tire are mounted on the radially inner periphery of the rim. In order to prevent dirt and/or water from entering the space between the tire bead and the rim well, the covering ring has a width which covers the space between the tire bead, that portion of the rim which extends axially outwardly from the rim well, and the rim well. Also provision is made that the radially inner surface of the covering ring, when viewed in the transverse direction, extends horizontally or is laterally inclined toward the outside. Also provision is made that the radially inner diameter of the covering ring at no point of the space, which is to be covered, be greater than the radially inner diameter of the mounted tire in the bead region.
