Definitions
- the invention relates to a pneumatic vehicle tire, in particular a commercial vehicle tire, having a tread, which has a tread cap and a tread base, each made of a rubber compound, and having at least one multi-layer belt structure with at least one Undertread covering the belt edges and separating them from the tread base.
- Strip made of a rubber mixture.
- Reinforcing member ends (belt edges), the occurring high deformations and the associated mechanical stresses belt edges are also exposed to high structural loads.
- the stresses and strains can result in belt edge loosening and belt edge separation which not only compromise retreadability but can also result in complete belt detachment until the tire is destroyed.
- carbon blacks are used in the tread base rubber composition which have lower activity (a lower BET surface area and a lower CTAB surface area) than the carbon blacks used in the tread cap blend.
- the total filler content is also in the base mix lower than that in the cap mix. Therefore, the hardness of the tread base is often less than the hardness of the tread cap.
- EP-A-1 031 441 it is proposed to effectively lower the temperature of rubber compounds in the belt-near region of pneumatic vehicle tires to arrange a rubber compound whose profile is at least 5% higher than that on the groove surface and / or in the region of the tire shoulders
- Thermal conductivity of the surrounding rubber compounds To increase the thermal conductivity of the mixtures, fillers such as aluminum, magnesium, copper, tin, nickel or metal-containing substances such as zinc oxide, aluminum hydroxide and the like are proposed as additives in addition to carbon black.
- the invention is based on the object, a particularly effective measure for
- the tread base has at least 20% higher thermal conductivity than the tread cap and at least 10% higher thermal conductivity than the orertread strip.
- the higher thermal conductivity of the tread base can be achieved by the use of acetylene black in the starting mixture.
- the tread base contains at least 25 parts by weight, in particular between 42 and 60 parts by weight of acetylene black, based on 100 parts by weight of rubber in the starting mixture.
- the tread base For the crack resistance of the tread base, it is favorable if its Shore A hardness is lower by at most two points than that of the tread cap. This measure prevents unwanted stress concentrations and, above all, avoids fatigue cracking in the tread base.
- the crack resistance of the tread base can also be favorably influenced by the use of certain rubber types. It is advantageous if the tread base is made of a rubber mixture, which 55 to 100
- the tread base is made of a rubber mixture
- the sulfur content is between 0.5 to 2.5 times the accelerator proportion.
- the orertread strip (s) are preferably made of a rubber compound containing a steel cord adhesion system. This measure promotes good adhesion of the Undertread strip (s) to the steel cord cutting edges of the belt plies.
- the tread base should be located in the tire so that it lies completely inside the tire and does not reach into the lateral outer regions of the tire.
- the abrasion resistance of the tread base can be increased by using, in addition to acetylene black, between 5 and 20 parts by weight of a type N 326 carbon black and / or a type N 339 carbon black.
- Fig. 1 and Fig. 2 partial cross-sections through a tire in the region of the tread and the belt with two different embodiments of the invention.
- the drawing figures show in cross-section one of the upper side wall portions and the subsequent tread region of a commercial vehicle tire.
- the illustrated conventional components of the tire are standard constructions, for example the carcass ply 2, which is provided in particular with steel cords as strength members, the airtight inner layer 1, the belt bandage consisting of four plies 3, 4, 5 and 6 and the side wall 10. Between the belt bandage, the carcass ply 2 and the side wall 10 is a shoulder pad 11 is introduced.
- the tread consists of a tread cap 9 and a tread base 8, the edges of the belt layers 4, 5 and 6 are covered with a Undertread strip 7 (Fig.1) and T (Fig. 2).
- tire components for example, the bead areas, may be performed in a known manner.
- the fourth, radially outermost belt ply 6 has the smallest width of all plies and is the so-called protective ply, which already ends relatively far from the shoulder regions of the tire.
- the first belt layer 3 is the so-called blocking position
- the second belt layer 4 and third belt layer 5 are the so-called working positions.
- All belt layers 3, 4, 5 and 6 consist of a rubber compound, the Gürtelgumm ist embedded reinforcements, in particular steel cord.
- the steel cords in each of the layers 3, 4, 5, and 6 are parallel to each other, but enclose an angle with the circumferential direction of the tire. This angle is generally 5 ° to 25 ° for the steel cords of the fourth belt ply 6, for the steel cords of the second and the third
- Belt layer 4, 5 between 15 ° and 25 °, wherein the steel cords of the belt layers 4, 5 intersect each other, and for the steel cords of the first belt layer 3 between 45 ° and 70 °.
- a belt pad 12 made of a rubber compound is inserted between the lateral edge portions of the second and the third belt ply 4, 5.
- the cover strip 7, 7 ' which usually covers the edge portions of the belt plies 5, 6, the belt cushion 12 and the edge of the belt ply 4, consists of a rubber compound and prevents it
- Further belt construction variants with 3 to 5 belt plies or 4- or 5-ply variants with belt ply angles exclusively between 5 ° and 25 ° are possible for use. Even belt variants in which one or two layers have an angle of 0 ° to 5 ° can be used.
- the tread base 8 extends radially inside the cap 9 laterally to the side walls 10 and has a substantially constant thickness, which is at least 1 mm, at most up to 8 mm.
- the tread base 8 is made of a particularly thermally conductive rubber compound, its thermal conductivity is at least 20% higher than the thermal conductivity of the tread cap 9. Compared with the rubber mixture used for the Undertread strip 7, T, the tread base 8 at least one 10% higher thermal conductivity.
- the thermal conductivity of the tread base 8 is achieved by the use of acetylene black as a filler.
- the proportion of acetylene black in the mixture for the base 8 is at least 25 parts by weight, based on 100 parts by weight of rubber in the mixture.
- At least one further type of carbon black can be used in addition to acetylene black.
- the total amount of carbon black should be at least 40 parts by weight based on 100 parts by weight of rubber in the mixture.
- only acetylene black can be used.
- the optimum proportion of acetylene black in the mixture is between 42 and 60 parts by weight.
- Acetylene black is produced by thermal decomposition of acetylene and is characterized by an above-average proportion of graphite-like structures and a very low content of oxygen-containing groups.
- Acetylene blacks typically have a DBP number (dibutyl phthalate number) in accordance with ASTM D 2414 from 150 to 260 cm3 / 100 g and an iodine adsorption number according to ASTM-D 1510 greater than 85 g / kg.
- the particle diameters of the primary particles are between 30 and 45 nm.
- the further carbon blacks optionally added to the tread base mixture are preferably abrasion-resistant carbon blacks whose proportion is from 5 to 20 parts by weight.
- High abrasion resistant carbon blacks are furnace carbon blacks characterized by a high structure with small particle size. These carbon blacks exhibit an iodine adsorption number 75-105 g / kg and a DBP the number of 60 to 160 cm3 / 100 g. Particularly suitable are N 326 or N 339 type carbon blacks.
- the Shore A hardness of the tread base 8 should be at most 2 points lower than that of the tread cap 9. This measure prevents unwanted stress concentrations in the runway base 8 during operation of the tire and avoids
- the hardness of the tread base 8 should be between Shore-A 55 and Shore-A 70.
- the lower crack resistance of the tread base 8 can also be somewhat compensated by the use of natural rubber.
- butadiene rubber can be used as the second rubber component in the mixture for the tread base 8, since this rubber type has excellent tear resistance and tear propagation resistance at low elongation amplitudes.
- the proportion of butadiene rubber should not exceed 35 parts by weight.
- other types of rubber can basically be used in rather small amounts may be added, for example styrene-butadiene copolymer (SBR 1 E-SBR, S-SBR), synthetic polyisoprene (IR) and polybutadiene (BR), the total amount of other rubber types should not exceed 10 parts by weight.
- the vulcanization system used is a sulfur accelerator system in which the sulfur content is 0.5 to 2.5 times as high as the accelerator fraction.
- sulfur accelerator system for example, thiuram derivatives or morpholine derivatives can be used as sulfur donors. Due to the low tear strength of the tread base 8, direct contact of the tread base 8 with the cut edges of the cords in the belt plies 3 to 6 should be avoided.
- the Undertread Strip 7, T prevents direct contact and is preferably made from a rubber compound that ensures high tear resistance.
- the rubber mixture for the Undertread Strip 7, T should either contain no acetylene black or only a small proportion of acetylene black of at most 15 parts by weight.
- the Undertread strip 7, T has a substantially constant
- Thickness of 0.1 to 3 mm. It can be provided, as shown in FIG. 1, that in each case a strip 7 covers substantially only the edge regions of the belt layers 4, 5, and 6, but it can be provided that the strip 7 'over the entire width of the belt or tread runs, as shown in Fig. 2.
- the higher heat build-up in the mixture of the strip 7, T due to the steel cord adhesion system is in any case more than compensated by the high thermal conductivity of the tread base 8.
- Table 1 contains a blend example (M1) for a typical tread cap blend and two blend examples (M2 and M3) of a tread base blend made in accordance with the present invention. The amounts given are parts by weight (phr) based on 100 parts by weight of rubber in the mixture. From the mixtures test specimens were prepared by vulcanization at 160 0 C. These specimens are used to determine some typical material properties for the rubber industry, the values of which are given in Table 2. The following test procedures were used for the tests on the test specimens:
