- the belt bandage may be formed in one or more layers, covers at least the belt edges and contains parallel and in
- Substantially circumferentially extending strength members in the form of cords embedded in a rubber composition are at the
- the reinforcing elements are embedded in rubber for such layers, for example, by a group of substantially parallel filiform reinforcing elements, which are usually pretreated by thermal and / or for better adhesion to the embedding rubber in the conventional manner with an impregnation impregnated in the longitudinal direction Calender or an extruder to coat with the rubber compound. Or it will be
- Reinforcements used which are tacky impregnated and can be processed without a calendered adhesive mixture.
- the tire When the tire is cambered and cured, the tire typically extends up to 2% in the shoulder area and up to 4% in the center area as compared to the unvulcanized blank when this blank is wound on a flat drum.
- Reinforcements which is used in the belt bandage, advantageously allow this survey, so initially can be stretched with less effort, but can be stretched after this initial strain to 4% for high speed capability with only greater effort. In a force-elongation diagram, the reinforcement should therefore have a flatter course and then a steeper course up to an extension of 4%.
- the belt bandage is single or multi-layered, covers the belt edges, and has parallel and approximately circumferentially extending reinforcements in the form of rubber-embedded cords. "Circumferential" means an angle of 0 ° to 5 ° with respect to the tire circumferential direction ,
- Twisted polyamide 6.6 filaments, yarns and cords are known from US 3,343,363 A as strength reinforcements for tires having an initial modulus of between 25 and 60 g / d and a tenacity of greater than 7.0 g / d at room temperature exhibit.

- US 5,115,853 A discloses 420 d x 2 (470 dtex x 2) nylon cords with a twist of less than 276 t / m and used in the belt bandage of pneumatic vehicle tires.
- Reinforcing layer which has improved high-speed properties and improved rolling resistance.
- the object is achieved in relation to the reinforcing layer in that the raw yarn of polyamide 6.6 has a fineness-related strength, which at an elongation of 4% in a range from 1.35 cN / dtex to 1.60 cN / dtex, that the Cord has a fineness-related strength, which at an elongation of 4% in a range of 1.2 cN / dtex to 2 cN / dtex and that the cord has a heat shrinkage at 177 ° in a range of 4.0% - 7, 0%, wherein the tenacity was determined according to ASTM D885-16 and the heat shrinkage at 177 ° C under a bias of 0.045 g / dtex with two minutes exposure time.
- Raw yarn means a multifilament yarn which is not yet hot-drawn.
- Core means reinforcements with multifilament yarns, which is the process of
- Reinforcement polyamide 6.6 of 1400x2 construction at 4% elongation shows the advantage of a higher fineness-related strength of the reinforcement (B) used in a reinforcement layer according to the invention compared to a standard reinforcement (A) in a reinforcement layer of the prior art:
- the polyamide 6.6 cords for the reinforcing ply according to the invention are obtained by the polyamide 6.6 raw yarn used having a fineness-related strength which at an elongation of 4% ranges from 1.35 cN / dtex to 1.60 cN / dtex and that this raw yarn is drawn in a range greater than 5% and less than 12% at temperatures between 230 ° C and 250 ° C and suitable coils with a voltage between 150g and 500g per
- the force-strain data of the cords are determined according to D885-16, according to the
- Tenacity at 4% elongation of 1.2 cN / dtex to 2.0 cN / dtex corresponds to a modulus of from 30.6 g / dtex to 51 g / dtex (34 g / d to 56.7 g / d).
- Modulus values are calculated as follows: Fineness-related strength at 4% elongation x 25 to obtain the required tenacity for 100% elongation.
- the fineness-related strength at 4% elongation [cN / dtex] is: tensile force at 4% elongation [cN] / fineness [dtex], the fineness of the entire reinforcement being used.
- the fineness of the entire reinforcing agent is calculated from the sum of the finenesses of the multifilament yarns of the cord.
- Example: A 700dtex x 2 construction cord has a fineness of 1400 dtex throughout.
- the heat shrinkage of yarns or cords is determined with a shrink meter manufacturer Testrite under a bias of 0.045 g / dtex at 177 ° C with 2 minutes exposure time.
- the raw yarn of polyamide 6.6 prefferably has a fineness-related strength which, at an elongation of 4%, lies in a range from 1.35 cN / dtex to 1.50 cN / dtex. If the forces were even higher, they could lead to problems during molding.
- the cord has a fineness of 300 to 4000 dtex. This fineness range represents an advantageous compromise in terms of strength on the one hand and rolling resistance or costs on the other. If the fineness were too low, ie the multifilament yarn was too thin, the strength would be too low. Would be that Multifilament yarn too thick, this would be detrimental to the rolling resistance of the tire and disadvantageous in terms of cost.
- the twist factor is a measure of the final twist per meter of the cord, based on the fineness of the cord.
- the twist factor is a measure of the twist per meter of multifilament yarn, based on the fineness of the multifilament yarn. This twist factor represents an advantageous compromise in terms of fatigue resistance and strength. A lesser twist factor would be detrimental to the
- Fatigue resistance a higher twist factor would mean lower strength of the strength member.
- the cord has the construction x2 or x3.
- a cord of 2 or 3 yarns has a better fatigue resistance than a twisted one
- each reinforcing layer of the reinforcing layer is a cord of two mutually twisted multifilament yarns, each having a yarn count of 1400 dtex.
- the cord thus has the construction 1400x2.
- the cord has a fineness-related strength, which at an elongation of 4% ranges from 1.3 cN / dtex to 1.4 cN / dtex.
- the cords are preferably arranged at a density of 90 epdm in the reinforcing ply.
- each reinforcing layer of the reinforcing layer is a cord of two mutually twisted multifilament yarns, each having a yarn count of 470 dtex.
- the cord thus has the construction 470x2.
- the cord has a fineness-related strength which, at 4% elongation, is in the range of 1.6 cN / dtex to 1.7 cN / dtex.
- the cords are preferably arranged in a density of 90 to 100 epdm in the reinforcing layer.
- Semi-finished product is damaged when cutting into the required strip width.
- jeer reinforcement of the reinforcing layer is a cord made of two mutually twisted multifilament yarns, each having a yarn count of 350 dtex.
- the cord thus has the construction 350x2.
- the cord has a fineness-related strength, which at an elongation of 4% is 1.9 cN / dtex.
- the cords are preferably arranged in a density of 110 to 130 epdm in the reinforcing layer. Due to the increased compared to the prior art module of PA6.6 Cordes this can be in a lower density in the
- the reinforcing layer is a belt bandage layer, wherein the
- the polyamide 6.6 cord is due to its physical properties especially for use in a
- the reinforcement layer may alternatively be a bead enhancer such as a chipper or flipper.
- the invention is solved with respect to the vehicle pneumatic tire by having a rubberized reinforcing layer as described above.
- the pneumatic vehicle tire has an improved rolling resistance. At a higher strength density in the
- the vehicle pneumatic tire also has an improved
- the reinforcing layers according to the invention have reinforcements made of polyamide 6.6 of construction 1400x2, which are arranged in a density of 90 epdm in the reinforcing layer.
- reinforcing layers of the prior art were tested, which have strength of standard polyamide 6.6 construction of 1400x2 in a density of 110 epdm. Table 2 below shows the results of these tests:
- Reinforcement layer despite a significantly lower density of reinforcements is about the same height as in the reinforcing layer of the prior art. It is also evident that advantages in terms of rolling resistance are achieved.
- the reference tire of the prior art has a rolling resistance of 100%, while the tire with the reinforcing layer according to the invention has reached 101.3%. Higher% values indicate better rolling resistance.
