Abstract
Abstract The vehicle wheel comprises a rim containing an external closed ring and an internal rim ring composed of three segments and connected to a segmentally separated or segment-shaped divided disc. The beads of the pneumatic tire lie in grooves disposed between the external closed ring and the internal rim ring. Each of these grooves is formed by a bead seat, a vertical web and the external closed ring. Due to the internal pressure of the air in the pneumatic tire, each tire bead is drawn against clamping surfaces of the associated groove and sealed in relation to the external closed ring.

Claim 1
Independent Claim
147 words
A vehicle wheel for mounting of a pneumatic tire having tire beads, particularly for commercial vehicles, comprising: a rim having an outer-situated rim part possessing a radially inner circumference against which bear the tire beads of the pneumatic tire; said rim being provided with a respective groove for receiving an associated tire bead of the pneumatic tire; said outer-situated rim part comprising an external, circumferentially closed ring, said rim further including an internal rim ring cooperating with said external circumferentially closed ring; said grooves being formed conjointly by said external circumferentially closed ring and said internal rim ring; said external circumferentially closed ring being separate from but engaging said internal rim ring and being separately insertable into said pneumatic tire; an attachment flange fixedly connected to said internal rim ring; and said internal rim ring together with said attachment flange being circumferentially separated and comprising three segments.
Claim 2
Dependent Claim
147 words
A vehicle wheel for mounting of a pneumatic tire having tire beads, particularly for commercial vehicles, comprising: a rim having an outer-situated rim part possessing a radially inner circumference against which bear the tire beads of the pneumatic tire; said rim being provided with a respective groove for receiving an associated tire bead of the pneumatic tire; said outer-situated rim part comprising an external, circumferentially closed ring, said rim further including an internal rim ring cooperating with said external circumferentially closed ring; said grooves being formed conjointly by said external circumferentially closed ring and said internal rim ring; said external circumferentially closed ring being separate from but engaging said internal rim ring and being separately insertable into said pneumatic tire; an attachment flange fixedly connected to said internal rim ring; and said internal rim ring together with said attachment flange being circumferentially separated and comprising three segments.
Claim 3
Dependent Claim
60 words
The vehicle wheel as defined in claim 1, wherein: said segments are arranged in circumferentially neighboring relationship to one another and defining adjacent each two neighboring segments, separation surfaces; and said separation surfaces of said segments in the region of said internal rim ring possessing a substantially V-shaped configuration in order to provide a mutual form-locking contact of said segments.
Claim 4
Dependent Claim
87 words
The vehicle wheel as defined in claim 2, wherein; said attachment flange comprises a disc provided with a centering bore; said separation surfaces of said segments being spaced at a predetermined distance from one another in the region of said disc to form slots; said slots extending from said internal rim ring to the region of said centering bore; and each said slot possesses a width dimensioned such that each of said segments can be pushed together to facilitate mounting of a pneumatic tire on the rim.
Claim 5
Dependent Claim
90 words
The vehicle wheel ad defined in claim 1, wherein: said internal rim ring possessing bead seats which extend substantial in conformity with the outer contour of the tire beads; a respective circumferentially extending substantially radially projecting web provided for reach groove and extending between said external circumferentially closed ring and said internal rim ring; and each said groove is formed by said external circumferentially closed ring, a respective one of said bead seats of said internal rim ring, and an associated one of said circumferentially extending substantially radially projecting webs.
Claim 6
Dependent Claim
24 words
The vehicle wheel as defined in claim 4, wherein: said circumferentially extending substantially radially projecting webs are arranged on said external circumferentially closed ring.
Claim 7
Dependent Claim
23 words
The vehicle wheel as defined in claim 4, wherein: said circumferentially extending substantially radially projecting webs are arranged on said internal rim ring.
Claim 8
Dependent Claim
69 words
The vehicle wheel as defined in claim 6, wherein: said internal rim ring has a central region; said external circumferentially closed ring possessing a recess; said internal rim ring possessing at said central region of the rim a circumferentially extending web means which engages in said recess of said external circumferentially closed ring; and said recess being configured in correspondence with said circumferentially extending web means for reception thereof.
Claim 9
Dependent Claim
47 words
The vehicle wheel as defined in claim 1, further including: means defining at least one form-locking connection for transferring torque and arranged between said internal rim ring and said separate external circumferentially closed ring; and said external circumferentially closed ring is constructed as a run flat ring.
Claim 10
Dependent Claim
