Abstract:
A filler ring for a vehicle wheel and pneumatic tire assembly, in which the beads of the tire are mounted on the radially inner periphery of a drop-center wheel rim adjacent essentially radially inwardly extending rim flanges. The filler ring fills a space located between a tire bead and a wall of the drop-center. The filler ring is provided with a plurality of circumferentially extending hollow chambers that are disposed in two planes which are superimposed over one another in a radial direction and are separated from one another via a diagonal rib. Each of the planes of hollow chambers is provided with at least two hollow chambers that are successively arranged in an axial direction. The filler ring has a side wall that rests against a tire bead and extends perpendicular to the axis of rotation, and an oppositely disposed inclined wall that extends at approximately 80.degree. to the axis of rotation. The diagonal rib extends between a radially inner half of the side wall and a radially outer half of the inclined wall. To better prevent shifting of the filler ring radially inwardly, the diagonal rib forms an angle of less than 75.degree.-85.degree. with a radially inner half of the inclined wall.
Abstract:
A vehicle wheel has a wheel body or hub, an annular rigid rim mounted on it and an elastic inflatable tire mounted on the rim, the beads of the tire engaging annular recesses present on the inner face of the rim. The rim is provided with side flanks of the same curvature matched to the curvature which the flanks of the tire take up in operation, and between which is provided an annular engaging surface extending over the whole width of the rim from flank to flank, this surface giving the wheel good emergency characteristics. The inserts in the beads of the tire do not need any thickened beads which would adversely affect the resilience of its side walls, but only need to be made constructionally and to hold the reinforcing cords. The rim is made in one piece of a light material such as plastics or aluminum and can form an air reservoir for compressed air which is under high pressure and which automatically replenishes the tire when needed.
Abstract:
A vehicle wheel having a rigid rim on which can be mounted a pneumatic rubber tire. The tire beads are adapted to be disposed on the radially inner side of the rim ring. Deep mounting beds are located axially inwardly of the rim seating surfaces for the tire bead. In order to prevent the penetration of water and dirt into the deep mounting beads, the tire beads each have a cross-sectional shape which on the one hand during mounting allow the tire bead to enter the mounting space having the deep bed, and on the other hand in the operating position of the tire close off the mounting space having the deep bed region.
Abstract:
A vehicle wheel having a rigid wheel rim upon which a pneumatic belted tire is mounted. The beads of the tire contain pull-resistant cores, and are secured by a wheel flange against sliding laterally from the seating surfaces. A recess for receiving a tire bead during mounting of the tire is located adjacent to the seating surface on that side facing the rim middle. The seating surfaces are arranged on the inner periphery of the rim adjacent to a radially inwardly extending wheel flange. The base of the recess has a larger diameter than do the seating surfaces. The mantle surfaces of the rim adjacent to the recess are essentially even or smooth supporting surfaces for the tire zenith or crown portion during emergency operation of the tire. The middle portion of the rim, between the mantle surfaces, is also embodied at least partially as a supporting surface for the tire zenith portion during emergency operation of the tire, and the supporting surface lies essentially at the level of the mantle surfaces.
Abstract:
The drawings illustrate a tire and wheel arrangement wherein the wheel rim is formed to include radially outwardly diverging walls having annular "run-flat" shoulders formed on the outer periphery thereof. Inwardly directed walls with arcuate shaped inner end portions extending generally toward one another are formed on the shoulders. The tire is formed to include inverted bead portions which mount and seal around the respective inner end portions, accommodating the positioning of the run-flat shoulders within the tire.
Abstract:
A vehicle wheel for pneumatic tires. The rim of the wheel has radially inwardly extending rim flanges, and adjacent thereto, along the inner periphery, has seats inclined in cross section for a belted tire, and adjacent thereto, has recessed portions. The recessed portions adjoining the seats extend at least partially inclined in cross section. The angle of inclination of the recessed portions with respect to the axial direction is equal to or greater than the corresponding inclination angle of the seats. The recessed portions, in the axial direction, have a dimension which is equal to or greater than that of the axial segments of the seats.
Abstract:
A bead core for a pneumatic vehicle tire that is designed to have its beads disposed on the radially inner periphery of a rim. The bead core is in the form of an endless ring that has an essentially round cross-sectional shape. To increase the bead-seating reliability, it is proposed that the inner core of the bead core be hollow or be formed by a lightweight ring that serves as a spacer element. At least one layer of load-carrying cords is disposed about the inner core. These load-carrying cords have a solid cross-sectional area or a hollow cross-sectional shape.
Abstract:
A one-piece rim for a vehicle wheel, especially a truck wheel, on which a pneumatic tire is to be mounted. The rim ring is provided laterally outwardly with rim flanges which extend essentially radially inwardly. Disposed next to these rim flanges, on the radially inner side of the rim ring, are respective seating surfaces for a tire bead. To secure the tire beads on the rim, even in extreme driving situations, the rim ring includes two parts which are undetachably connected with one another and/or the wheel-center disk. Provided laterally inwardly of each rim flange is a respective one-piece clamping ring, which has an outer diameter which is greater than the inner diameter formed by the rim flanges. Spring or snap rings are provided for fixing the clamping rings in position against the tire beads.
