Abstract

A pneumatic vehicle tire has at least a tread with an outer tread cap with a profiled tread surface, an inner tread base and at least one electrically conductive conductivity strip. The conductivity strip extends in a radial direction from the tread base, through the tread cap, to the tread surface. The tire further includes an electrically non-conductive belt bandage arranged under the tread base and the belt bandage has a multiplicity of gaps, a multi-ply belt, a carcass and side walls. The gaps in the belt bandage are filled with an electrically conductive material.

First claim

What is claimed is:

1. A pneumatic vehicle tire comprising:
a tread including: an outer tread cap defining a profiled tread surface; an inner tread base; and, at least one electrically conductive conductivity strip;
said conductivity strip extending in a radial direction from said inner tread base through said outer tread cap to said profiled tread surface;
an electrically non-conductive belt bandage arranged below said inner tread base and having a plurality of gaps formed therein;
said plurality of gaps of said belt bandage being filled with electrically conductive material;
a multi-layered belt;
a carcass;
side walls; and
wherein said tread base is made of a first electrically conductive material; and,
said at least one electrically conductive conductivity strip is made of a second electrically conductive material different from said first electrically conductive material of said the tread base.

2. The pneumatic vehicle tire of claim 1 , wherein said electrically conductive material of said plurality of gaps is an electrically conductive rubber mixture.

3. The pneumatic vehicle tire of claim 1 , wherein said tread base is made of a predetermined material; and, said gaps are filled with said predetermined material.

4. The pneumatic vehicle tire of claim 1 , wherein said belt bandage includes at least one ply of a woven fabric.

5. The pneumatic vehicle tire of claim 4 , wherein said woven fabric of said belt bandage is formed from one of the following: nylon or a hybrid material of nylon and aramid.

6. The pneumatic vehicle tire of claim 1 , wherein said gaps form a total area of at least 10 mm 2 .

7. The pneumatic vehicle tire of claim 1 , wherein at least one of said gaps has a width (b) lying in a range of 0.2 to 1.5 cm.

8. The pneumatic vehicle tire of claim 7 , wherein said width (b) of said one gap is 1.0 cm.

9. A pneumatic vehicle tire comprising:
a tread including: an outer tread cap defining a profiled tread surface; an inner tread base; and, at least one electrically conductive conductivity strip;
said conductivity strip extending in a radial direction from said inner tread base through said outer tread cap to said profiled tread surface;
an electrically non-conductive belt bandage arranged below said inner tread base and having a plurality of gaps formed therein;
said plurality of gaps of said belt bandage being filled with electrically conductive material;
a multi-layered belt;
a carcass;
side walls; and
wherein two mutually adjacent ones of said gaps are separated by a distance lying in the range of 0.2 to 1.5 cm.

10. A pneumatic vehicle tire comprising:
a tread including: an outer tread cap defining a profiled tread surface; an inner tread base; and, at least one electrically conductive conductivity strip;
said conductivity strip extending in a radial direction from said inner tread base through said outer tread cap to said profiled tread surface;
an electrically non-conductive belt bandage arranged below said inner tread base and having a plurality of gaps formed therein;
said plurality of gaps of said belt bandage being filled with electrically conductive material;
a multi-layered belt;
a carcass;
side walls;
wherein said plurality of gaps are formed at regular intervals from one another;
wherein said plurality of gaps are subdivided into groups formed to be at regular intervals from one another; and
wherein two mutually adjacent ones of said groups are separated by a distance lying in a range of 0.2 to 1.5 cm.

11. The pneumatic vehicle tire of claim 1 , wherein said carcass includes electrically conductive carcass cords; and, said gaps filled with electrically conductive material form an electrical contact between said electrically conductive cords and said electrically conductive strip.

12. The pneumatic vehicle tire of claim 9 wherein said tread base is made of a first electrically conductive material; and,
said at least one electrically conductive conductivity strip is made of a second electrically conductive material different from said first electrically conductive material of said the tread base.

13. The pneumatic vehicle tire of claim 1 , wherein the electrically conductive material of the plurality of gaps is the first electrically conductive material.

14. The pneumatic vehicle tire of claim 1 , wherein the plurality of gaps establishes electrical contact between a road and the carcass.

15. The pneumatic vehicle tire of claim 1 , further comprising a plurality of circumferential grooves formed in the profiled tread surface.

16. The pneumatic vehicle tire of claim 1 , wherein the plurality of gaps are continuous in a circumferential direction.

17. The pneumatic vehicle tire of claim 1 , wherein the plurality of gaps are arranged in a sequence of three gaps and/or eight gaps.

18. The pneumatic vehicle tire of claim 9 , wherein said electrically conductive material of said plurality of gaps is an electrically conductive rubber mixture.

19. The pneumatic vehicle tire of claim 10 , wherein said belt bandage includes at least one ply of a woven fabric.

20. The pneumatic vehicle tire of claim 10 , wherein the plurality of gaps establishes electrical contact between a road and the carcass.
