Description

The invention relates to a reinforcing strip for elastomeric products, in particular a reinforcing strip for reinforcing a bead region of a vehicle tire, wherein the reinforcing strip a plurality of first threads, which are arranged in a first layer substantially parallel to each other and embedded in elastomeric material, and a plurality of second threads which are arranged in a second layer substantially parallel to each other and embedded in elastomeric material, wherein the first threads and the second threads intersect at an angle, wherein the first threads and the second threads each comprise a polyamide monofilament. Furthermore, the invention relates to a tire having such a strength carrier band and a vehicle wheel having such a tire.

Reinforcing members for reinforcing various elastomeric products, in particular for a carcass and / or a chafer of vehicle tires, are known to the person skilled in the art in construction and material in a wide variety of designs. The reinforcements are embedded, for example by calendering, in a rubber mixture in order to be used as a rubberized reinforcement layer in the elastomer product can.

It is known to provide in vehicle pneumatic tires, a Wulstschutzband, which consists of a rubberized fabric strip that extends to above the rim flange and is guided around the tire bead. The bead protection tape has the task to protect the tire during assembly, disassembly and operation on the rim from damage.

The DE 3302867 A1 discloses a pneumatic vehicle tire which has a bead protection band in the region of the contact surfaces on the rim. The chafer contains a fiber-rubber mixture in which fibers made of polyamide 6.6 are firmly embedded in the rubber.

Commonly used as protection of the bead is also an antiperspirant tape comprising a plain weave fabric with monofilaments of polyamide 6.6 as threads. Such simple monofilaments of polyamide 6.6, however, have a high thermal shrinkage. This results in the tire heating to high local stresses in the threads, which reduces the durability and the associated protective function of the bead protection tape on the finished tire.

The object of the invention is to provide a reinforcement layer which has improved durability when used as a bead protection strip on the vehicle tire.

The object is achieved by the first threads and / or the second threads yarns formed from a polyamide monofilament or from two, three or more polyamide monofilaments, preferably from one or two polyamide monofilaments, more preferably from exactly two polyamide monofilaments , are and in that the yarns each have a twist.

A "yarn" is in the context of the present invention based on the DIN 60900 a line-shaped structure, which is formed from at least one monofilament. A yarn has a twist when either the one monofilament of the yarn is twisted or when the multiple monofilaments of the yarn are twisted together. A "polyamide monofilament" is a monofilament formed entirely or partially of polyamide.

Significant here is the special construction of the yarns. The first threads and / or the second threads are each formed either of exactly one polyamide monofilament, wherein the polyamide monofilament has a twist. Or the first threads and / or the second threads are each formed exactly from two, three or more polyamide monofilaments which are twisted together. By this twisting of the yarns yarns are provided which have a favorable tensile-elongation behavior both before and after the tire heating for vulcanization. Local stresses, which can be generated by the temperature shrinkage of the polyamide material in the heated strength carrier strip, are greatly reduced by this construction of the yarns. Such a strength carrier belt withstands far greater stress and places less demands on the physical and physico-chemical properties of the elastomer mixture surrounding the filaments. When used as a chafer of a vehicle tire, the durability of the bead protection strip is improved and thus the bead is better protected against damage.

It has proved to be advantageous if the yarns are each formed from a twisted polyamide monofilament.

It has proven to be particularly advantageous if the yarns are each formed from two twisted polyamide monofilaments.

It is expedient if the first threads and the second threads are formed as corresponding yarns. It is expedient if, in terms of their construction and their material, are the same. It is particularly expedient if the first threads and the second threads are each formed as yarns of two mutually twisted polyamide monofilaments.

As a particularly suitable material for the monofilaments of a bead protection tape is polyamide 6.6 or polyamide 6, preferably polyamide 6.6, has been found. These materials have excellent force-elongation properties, in particular for use as reinforcements of a bead protection band, at the same time low costs.

In a preferred embodiment, the first threads intersect with the second threads at an angle of at least 56 °, preferably from 80 ° to 100 °, more preferably from about 90 °. It is expedient if the first threads and / or the second threads in each case enclose an angle of at least 28 °, preferably 40 ° to 50 °, particularly preferably approximately 45 °, with the direction of the longitudinal extension of the band. As a result, an advantageous extensibility is achieved perpendicular to the longitudinal extent, which can lead to an improved application precision in the application of the tape to the intermediate products or the green tire. For a chafer on the tire, the longitudinal extent of the band corresponds to the circumferential direction of the tire. The extensibility is improved in the radial direction.

A further preferred embodiment is characterized in that the yarns have a twist of 180 tpm to 520 tpm, preferably from 280 tpm to 520 tpm, more preferably from 460 tpm to 480 tpm. As a result, an adapted to the thermal shrink optimum tensile-elongation behavior of the yarns is achieved. At a twist of less than 180 tpm (turns per meter), the geometric elongation of the yarns allowed by twisting is too low. A twist of more than 520 tpm, on the other hand, burdens the monofilaments too much, so that the durability of the yarns may decrease.

A preferred embodiment is characterized in that the yarns have a fineness of from 360 dtex to 1200 dtex, preferably 940 dtex. Yarns of such fineness have a good durability with low material usage.

It is advantageous if the yarns have a diameter of 0.25 mm to 1.20 mm, preferably from 0.40 mm to 0.70 mm, particularly preferably from 0.50 mm to 0.60 mm. A chafer with such yarns is particularly durable against damage during assembly or by stress through the rim.

It is convenient to mechanically, physically and / or chemically activate the surface of the filaments to ensure adhesion between the filaments and the elastomeric material. In order to ensure a reliable adhesion of the threads to the elastomeric material, it is expedient to coat the monofilaments and / or the threads with a bonding agent, e.g. a Haftimprägnierung to provide.

It has also turned out to be advantageous if the first threads and / or the second threads, in particular the threads, are arranged with a thread density of 35 epdm to 120 epdm, preferably 72 epdm to 110 epdm. The first threads and the second threads are preferably arranged with the same thread density.

A particularly simple embodiment is obtained when the reinforcement tape has two elastomeric layers, wherein the first threads in a first layer and the second threads are arranged in a different layer to the first layer. The first layer and the second layer can be produced separately from each other as precursors and then placed on top of each other.

A particularly small thickness of the reinforcement tape may result if the reinforcement tape comprises a textile fabric, preferably a textile fabric having a plain weave, a twill weave, also called a body weave, or an atlas weave, particularly preferably a textile weave having a plain weave, wherein the weave Has warp threads and weft threads and wherein the first threads are formed as warp threads and that the second threads are formed as weft threads of the fabric. As a result, in addition to the thickness of the band, the weight and the use of material are reduced to elastomeric material.

It is expedient in this case if the binding is binding and / or equilateral.

Such a strength carrier tape is ideal as a chafer for a vehicle tire. It can be a chafer for a pneumatic vehicle tire or a full vehicle tire, also known as solid tires. Such a chafer has excellent durability against tire assembly on a rim and disassembly of the tire from the rim and during operation. This is particularly advantageous for one-piece rims, as these make special demands on the tire during assembly and disassembly of the tire.

The invention further comprises a vehicle tire for mounting on a rim, wherein the Vehicle tire has a reinforcement layer according to the invention, in particular a bead protection strip. The bead protection band can be arranged as the outermost reinforcement layer in the bead region of the tire. The bead protection band can form the outer surface of the tire, in particular in the region of the contact surface of the tire on the rim. As a result, the tire is particularly well protected against damage during assembly of the tire on the rim and during disassembly of the rim as well as damage by the rim during operation of the tire.

An abutment surface of the tire on the rim is a surface of the tire which is adapted to abut the rim on the tire mounted on a rim. The rim may be a disc wheel or a vehicle rim or a measuring rim according to E.T.R.T.O. or T.R.A. or JATMA or other specifiers, preferably a measuring rim according to E.T.R.T.O., act. The rim can also be a disk wheel or a vehicle rim or measuring rim, which follows in its dimensions the specification of an individual wheel rim manufacturer. For example, specifications relating to rim shoulder dimensions, such as rim flange height, or rim or wheel rim dimensions, may be found in the corresponding descriptions of the rim in accordance with E.T.R.T.O., T.R.A. or JATMA or refer to the product specification of the respective rim manufacturer or disc wheel manufacturer. It may be a measuring rim according to E.T.R.T.O. act.

As a rule, the bead protection strip is arranged at a distance from a further layer of reinforcing material, in particular to the carcass and / or a bead reinforcement, by a rubber layer. The bead protection band is generally arranged annular in the direction of rotation.

The vehicle tire may be a vehicle tire comprising rubber of conventional design suitable for mounting on a rim. The tire may be suitable for a steep shoulder rim and / or for an oblique shoulder rim and / or for a flat shoulder rim. Particularly suitable is such a Wulstschutzband for tires in which special demands on the tire in terms of assembly and disassembly, the frequency of assembly and disassembly, the selected disc wheel or the rim and the conditions of use of the vehicle and thus the vehicle tires are provided.

It can be a pneumatic vehicle tire. In particular, such a pneumatic vehicle tire has two tension-resistant bead cores, a carcass which extends from one bead core to the other bead core and is anchored by looping around the tension-resistant bead cores. The bead area can have a bead protection band. The bead area can also be designed without bead protection band. The carcass may then have the reinforcement layer adjacent to the bead protection strip.

It may in particular be a pneumatic vehicle tire for a passenger car, for a light commercial vehicle, for a van, for a, in particular for heavy duty suitable, commercial vehicle, for an agricultural vehicle, for an industrial vehicle, for a forklift or for an earthmoving machine. It can be a pneumatic vehicle tire.

The vehicle tire may also be a full vehicle tire. The reinforcement strip may extend as a bead protection band from the contact surface of the tire on the bead seat surface to the contact surface of the tire on the rim flange. Also, such a tire has improved wear resistance with respect to the bead area due to a chafer.

In particular, it may be a full vehicle tire for an agricultural vehicle, for an industrial vehicle, for a forklift or for an earthmoving machine, or for other vehicles that move high loads at low speeds.

It can be a radial tire or a bias tire.

It is expedient for the vehicle pneumatic tire to have a bead protection strip which is guided from the inside axially from a first contact surface of the tire to a bead seat surface of the rim axially outward to a second contact surface of the tire on a rim flange of the rim. As a result, the transition from the first contact surface to the second contact surface is particularly well improved in its durability.

The durability of the tire, especially in the region of the second contact surface, is improved when an axially outer end of the bead protection band ends in the region of the second contact surface or radially outside the second contact surface. In a vehicle pneumatic tire mounted on a rim, it may extend radially outward of a rim flange height of the rim. With a small radial extent an improvement in durability is already possible with low material usage. At a radial extent beyond the second support surface and / or the rim flange height is the protection the bead further improved both during operation and during assembly or disassembly.

It is expedient if the axially outer end of the bead protection band is arranged radially within an axially outer end of a carcass ply turn-up and / or an axially outer end of a possibly arranged bead reinforcement.

If the radial height of the axially outermost end of the bead protection strip exceeds the rim flange height, then it is expedient if it exceeds this by 4 mm to 16 mm.

The durability of the tire v. A. is improved in the region of the first contact surface when the bead protection band is arranged at least within a partial region or at least in the entire region of the first contact surface.

Both in the case of full vehicle tires and also in the case of pneumatic vehicle tires, the bead protection strip can end within the region of the first bearing surface and extend radially outward with its axially outer end. In a pneumatic vehicle tire, however, it is preferred that the bead protection band loop around the bead from axially inside to axially outside and thus arranged in the entire region of the first contact surface and extend both ends of the bead protection band radially outward. If the bead region has a bead reinforcement, then it is expedient for the axially inner end of the bead protection strip to end radially inside an axially inner end of the bead reinforcement.

It is expedient if both beads of the vehicle tire have a reinforcement strip according to the invention as a bead protection strip. It is also expedient if the reinforcing strip is circumferentially arranged circumferentially and closed.

The invention further comprises a vehicle wheel comprising a disc wheel consisting of the rim and the wheel disc and a vehicle tire mounted on the rim.
