Embodiment Construction

[0045] figure 2 Shows a section through the tread area and the belt area of ​​a vehicle pneumatic tire for trucks having a conventional standard construction with a carcass 1 having as reinforcement The steel cords of the member; the air-impermeable inner layer 2; the multilayer belt assembly 3; and the shaped tread 6.

[0046] The belt assembly 3 has four belt layers 7 , 8 , 9 and 10 , of which the radially outermost fourth belt layer is the smallest in width among all the layers and forms a so-called protective layer 10 . The first belt layer is the so-called barrier layer 7 , the second and third belt layers are the so-called working layers 8 , 9 . The widest belt layer is the second belt layer 8 , which therefore completely covers the first belt layer 7 . The third belt layer 9 is slightly wider than the first belt layer 7 or has the same width as the first belt layer. The fourth belt layer 10 may further be implemented to have the same width as the third belt layer 9 ...

Abstract

The invention relates to a radial-type pneumatic vehicle tire, particularly a utility vehicle tire having a belt package (3) consisting of at least three layers (8, 9, 10), specifically two working layers (8, 9) and a protection layer (10), arranged radially on the outside in relation to the working layers (8, 9), wherein the protection layer (10) has reinforcing supports (11) consisting of one ormore steel filaments (12), which are stranded together, wherein the steel of the steel filaments (12) of the reinforcing supports (11) of the protection layer (10) has a strength class ST or a higherstrength class, the strength class ST having a tensile strength in MPa of 3980-2000 d and the strength class UT having a tensile strength in MPa of 4400-2000 d, and d being the diameter of a steel filament in mm.

Description

technical field [0001] The invention relates to a pneumatic vehicle tire of radial construction, in particular a commercial vehicle tire, having a belt assembly consisting of at least three layers, namely two working layers and a radially outer A protective layer of , wherein the protective layer has a reinforcing member consisting of one or more twisted steel filaments, wherein the steel of the steel filaments can be assigned a strength class. Background technique [0002] Commercial vehicle tires having a belt comprising two working layers and a protective layer are known to those skilled in the art. [0003] Typically, the belt of a commercial vehicle tire has four layers consisting of steel cords embedded in a rubber compound. In 4-layer belts, the radially innermost layer is designated as the "first belt layer" or, depending on its function, as the "barrier layer". A second belt layer and a third belt layer are arranged radially on the outside of the first belt layer,...
