PNEUMATIC VEHICLE TIRE

摘要

The invention is directed to a pneumatic vehicle tire having a carcass and a belt built up on the radial outside of the carcass. The tire includes a profiled tread which is built up on the belt on the radial outside of the belt. The belt is formed from at least four belt plies which are arranged one on top of the other from the radial inside to the radial outside. The first belt ply and the second belt ply are crossing working plies. The reinforcing elements of the first and second belt plies are arranged at an angle of 10° to 45° to the circumferential direction. The reinforcing elements of the fourth belt ply are arranged at an angle of 40° to 75° to the circumferential direction and the reinforcing elements of the third belt ply are arranged at an angle of 0° to 5° to the circumferential direction.

1. A pneumatic vehicle tire for utility vehicles, the pneumatic vehicle tire defining a circumferential direction (U) and a radial direction (R), the pneumatic vehicle tire comprising:
a carcass; at least four belt plies arranged resting one on top the other radially inward to radially outward and said plurality of belt plies conjointly defining a tire belt configured radially outside said carcass; a profiled tread constructed radially outside said belt and built up on said belt; said at least four belt plies including a first belt ply arranged furthest inwardly in the radial direction of said at least four belt plies; said first belt ply having a plurality of parallel first reinforcement members embedded in rubber; said at least four belt plies including a second belt ply arranged on said first belt ply, a third belt ply arranged on said second belt ply and a fourth belt ply arranged on said third belt ply; said second belt ply having a plurality of parallel second reinforcement members embedded in rubber; said third belt ply having a plurality of parallel third reinforcement members embedded in rubber; said fourth belt ply having a plurality of parallel fourth reinforcement members embedded in rubber; said first belt ply and said second belt ply being configured as working plies; said first reinforcement members each having an orientation which, together with the circumferential direction (U), encloses an angle α lying in a range of 10°≦α≦45°; said second reinforcement members each having an orientation which, together with the circumferential direction (U), encloses an angle γ lying in a range of 10°≦γ≦45°; said first reinforcement members having an opposite axial direction of inclination to said second reinforcement members as viewed in the circumferential direction U; said fourth reinforcement members each having an orientation which, together with the circumferential direction (U), encloses an angle ε lying in a range of 40°≦α≦75°; and, said third reinforcement members each having an orientation which, together with the circumferential direction (U), encloses an angle β lying in a range of 0°≦β≦5°.
