Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A bead ring assembly for vehicle tires comprising a ring-shaped rubberized wire bundle consisting of several wire layers arranged on top of one another, and a bead apex comprising elastomeric material arranged adjacent the wire bundle and adapted to extend in the direction of a side wall of a tire, wherein the wire bundle is wound from a single wire; the number of wire turns lying alongside each other is different in at least two of the wire layers which lie on top of one another; the number of wire turns lying alongside each other in the wire layer at the bead apex side is smaller, by at least two turns, than the number of wire turns lying alongside each other in the wire layer lying directly underneath it; and the bead apex lies on wire turns lying alongside each other of both the wire layer at the bead apex side and the wire layer lying directly underneath it in a form matched manner.
Claim 2
Dependent Claim
164 words
A bead ring assembly for vehicle tires comprising a ring-shaped rubberized wire bundle consisting of several wire layers arranged on top of one another, and a bead apex comprising elastomeric material arranged adjacent the wire bundle and adapted to extend in the direction of a side wall of a tire, wherein the wire bundle is wound from a single wire; the number of wire turns lying alongside each other is different in at least two of the wire layers which lie on top of one another; the number of wire turns lying alongside each other in the wire layer at the bead apex side is smaller, by at least two turns, than the number of wire turns lying alongside each other in the wire layer lying directly underneath it; and the bead apex lies on wire turns lying alongside each other of both the wire layer at the bead apex side and the wire layer lying directly underneath it in a form matched manner.
Claim 3
Dependent Claim
20 words
The bead ring assembly according to claim 1 wherein the diameter of the single wire is larger than 1 mm.
Claim 4
Dependent Claim
26 words
The bead ring assembly according to claim 1 wherein the diameter of the single wire is in the range of larger than 1 to 1.5 mm.
Claim 5
Dependent Claim
19 words
The bead ring assembly according to claim 1 wherein the wire bundle is constructed with a substantially hexagonal cross-section.
Claim 6
Dependent Claim
57 words
The bead ring assembly according to claim 1 wherein two wire turns are used for the wire layer at the bead apex side, and the two wire turns lie on the axial side intended to be disposed towards the inner wall of a tire, with the bead apex axially overlapping the two wire turns at one side.
Claim 7
Dependent Claim
48 words
The bead ring assembly according to claim 1 wherein a single wire turn is used for the wire layer at the bead apex side and the bead apex axially overlaps the wire turn on one side and contacts the underlying wire layer lying directly beneath the wire turn.
Claim 8
Dependent Claim
20 words
The bead ring assembly according to claim 6 wherein the bead apex axially overlaps both sides of the wire turn.
Claim 9
Dependent Claim
44 words
The bead ring assembly according to claim 1 wherein the ring area defined by the radially inwardly disposed wire layer tapers down conically in an axial direction, the ring area being adapted to taper in the direction of the inner side of the tire.
Claim 10
Dependent Claim
30 words
The bead ring assembly according to claim 8 wherein the angle of inclination of the ring area surface is approximately 5° relative to the axis of the bead ring assembly.
