Abstract
Abstract A vehicle wheel equipped with an annular solid rubber tire having its marginal portions provided with beads resting in and held by lateral wheel flanges. The rubber tire extends around an annular channel into which the tire can partially deflect. The wheel flanges are spreadable away from each other by spring tension.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
236 words
In combination: a vehicle wheel comprising a split rim having separate independent rim discs without rigid connection to each other, each rim disc having lateral wheel flanges axially spaced from each other for receiving tire beads radially outwardly thereon and also having rim extensions respectively connected to and directed radially inwardly from said wheel flanges and defining with each other an annular space extending radially inwardly therebetween with regard to the largest diameter surface of said wheel flanges; a solid rubber tire having beads resting radially on the axial outside of, and held respectively by, said lateral wheel flanges, said wheel flanges exerting outwardly directed axial forces upon said beads by means of spring tension, and said tire exerting inwardly directed axial forces on said rim discs, said tire extending across said annular space and being adapted to be partially deflected thereinto during springing-in of said tire; and additional intermediate coaxial means located between said rim discs and radially inwardly between said wheel flanges for supporting and detachably connecting said rim discs and for resisting said inwardly directed axial forces of said tire, said solid rubber tire and said additional intermediate coaxial means being individual parts which are assembled together safely under tensile and pressure forces into a functional unit without the necessity of any bonding connections, said tire and said coaxial means being suitably capable of being taken apart again for interchange and replacement purposes.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
30 words
An arrangement in combination according to claim 1, in which said tire beads are provided with substantially non-extensible bead cores and are arranged on the outside of said wheel flanges.
Claim 4
Dependent Claim
35 words
An arrangement in combination according to claim 2, in which said tire includes a carcass extending from wheel flange to wheel flange and having strength carriers embedded therein connected to and interconnecting said bead cores.
Claim 5
Dependent Claim
44 words
An arrangement in combination according to claim 3, in which said tire includes a tread ring surrounding said carcass and being connected thereto, said tread ring having both sides thereof provided with annular grooves decreasing in cross section in the direction toward each other.
Claim 6
Dependent Claim
22 words
An arrangement in combination according to claim 1, in which said extensions are resiliently spreadable in the axial direction of said wheel.
Claim 7
Dependent Claim
26 words
An arrangement in combination according to claim 5, in which said additional intermediate coaxial means comprises an annular elastomeric body interposed between and interconnecting said extensions.
Claim 8
Dependent Claim
31 words
An arrangement in combination according to claim 6, in which said annular elastomeric body comprises stiffening insert means for preventing said extensions from being offset radially with regard to each other.
Claim 9
Dependent Claim
36 words
An arrangement in combination according to claim 6, which includes a wheel body arranged radially inwardly of said annular channel, and in which said extensions are connected to said wheel body by said annular elastomeric body.
Claim 10
Dependent Claim
26 words
An arrangement in combination according to claim 8, in which the annular elastomeric body extends around said wheel body and is partly surrounded by said extensions.
Claim 11
Dependent Claim
29 words
An arrangement in combination according to claim 6, in which said extensions have angled off portions extending toward each other and forming supporting means for said annular elastomeric body.
Claim 12
Dependent Claim
84 words
An arrangement in combination according to claim 6, in which said extensions include angled off sections angled off in opposite directions with regard to each other, and which includes a wheel body arranged radially inwardly of said annular channel in radially spaced relationship thereto and having its outer periphery forming an annular supporting surface, and an annular elastomeric body clamped-in between said last mentioned angled off sections and said peripheral annular supporting surface of said wheel body while partially surrounding said annular supporting surface.
