Abstract: A vehicle tire contains a tread part, a bead region which is radially formed inside the tread part and having a bead core, a bead filler formed radially outside the bead core, and a bead reinforcing layer extending over a periphery of the vehicle tire and containing at least one resistance carrier spirally wound radially outwardly from the inside towards the periphery. A further bead reinforcing strip is formed radially inside the bead core, the further bead reinforcing strip extending axially over the entire axial length of the bead core and being radially outwardly folded back towards the two axial outer sides of the bead core. The further bead reinforcing strip having a first folded-back section extending up to a radial extension height from a vertex of the wheel rim and a second folded-back section up to a radial extension height from the vertex X of the wheel rim.

Abstract: A method controls the level of a pneumatic level-control system of a motor vehicle including at least two axles, at least one pneumatic spring (2a, 2b) per axle, optionally one or more pressure accumulators (3), at least one pressure sensor (24), elements (16, 18, 20, 22) for determining the distance between at least one wheel and/or an axle and the vehicle body, a control unit (10) and a compressor (12). The axle levels are controlled in sequence and adjusted from a starting level to a target level. During a positive adjustment operation the compressor (12) is at least operated temporarily and/or a connection of at least one pneumatic spring (2a, 2b) to the pressure accumulator (3) is established.

Abstract: A pneumatic spring and damper unit (1) has working chambers (2,3) which are filled with compressed air and are partially defined by rolled bellows or corrugated bellows. The working chambers are superimposed and connected through throttle valves, arranged inside a common pot-shaped cylindrical housing (4), and separated by a cylindrical piston (7), in such a way that one working chamber (2) is arranged on the front side of the piston and the other working chamber (3) is arranged on the rear side of the piston. The piston and the piston rod (5) are respectively sealed by roller bellows inside the cylindrical housing and guided therein, and the piston rod and the piston are interconnected by an articulation (6).

Abstract: A belt package for a pneumatic vehicle tire has at least two belt plies. The belt plies are built up in at least two sub-packages, which are automatically placed on a belt drum and automatically spliced independently of one another. The sub-packages are then joined together to form the complete belt package.

Abstract: Method and apparatus for positioning bead cores during a building of a radial tire carcass in a tire-building machine. The method includes positioning first and second bead cores on respective first and second core-centering devices, on a first side of a carcass drum and centering the first and second bead cores. Further, the method includes grasping, with a second core-setting device, the second bead core and transporting the second core-setting device and the second bead core to a second side of the carcass drum. Additionally, the method includes grasping, with a first core-setting device, the first bead core; and setting the first and second bead cores onto the tire carcass by the first and second core-setting devices.

Abstract: A method that can be used in the automated construction of a vehicle tire, using butt spliced tire components consisting of material webs, for example textile cords or steel cords that are embedded in a rubber mixture, to produce a carcass insert of the vehicle tire. The end sections of the cut material web can be clamped in a splicing device with pairs of upper and lower splicing elements, which can be displaced in relation to one another and the sections can be butt spliced.

Abstract: In a self-contained ride level control system for a motor vehicle, the accumulator pressure is controlled as follows: determination of the current pressure Ps(current) of the compressed air accumulator (4); definition of at least one level whereto the vehicle can be lifted or lowered; determination os the air volume required for lifting or lowering the motor vehicle from the current level and bringing it to a given level; determination of the subsequent accumulator pressure Ps(later) for reducing the current accumulator pressure Ps(current) if the motor vehicle is lifted from its current level up to the given level or determination of the subsequent accumulator pressure Ps(later) for increasing the current accumulator pressure Ps(current) if the motor vehicle has been lowered from the current level to the given level; filling the compressed air accumulator (4) with compressed air if the subsequent pressure Ps(later) is below a lower threshold value Ps (U) and emptying the compressed air accumulator if the sub

Abstract: A transportation and production system is used in building tire blanks having at least one carcass ply, an inner layer, sidewalls, two bead cores with core profiles, a belt assembly with at least two belt plies and a tread. Drums can be positioned on transportation devices and moved along at least one continuous transportation path, having stations to be delivered to for building tire components. Selected building stations have at least two respective stations that can be traveled to alternately.

Abstract: The invention relates to a sulfur-vulcanizable rubber compound, in particular for treads of tires, which contains at least one diene rubber, liquid polybutadiene with a molecular weight of 1500-10000 g/mol and a vinyl content of 15-50%, at least one polar filler, at least one high-structure black with an iodine adsorption number of 115-200 g/kg and a DBP number of 125-160 mL/100 g and at least one glyceride and/or one factice for good abrasion characteristics, good wet traction and good traction on ice and snow with good dry braking at the same time.

Abstract: A radial pneumatic vehicle tire, in particular a truck tire, includes a carcass insert having at least one ply and reinforcing elements of steel cord or a material of similar strength. The carcass insert is turned back in a bead region about a bead core to form a turn-up. At least one fabric reinforcing ply with tension-resistant, textile reinforcing elements, reinforces the bead region, runs around the bead core, has one side directly contacting the bead core and another side directly contacting the carcass insert and reaches on an inner tire side between a bead filler and the carcass insert, up to a height measured radially relative to a rim transition point of between 0.1 and 0.47 of a cross-sectional height of the tire and ending on an outer tire side, between the bead filler and the turn-up of the carcass insert, at a distance radially inside the turn-up.

Abstract: A compressor for a tire-repairing kit contains a second toothed wheel provided with a journal. The journal is functionally connected to a piston in such a way that the piston moves up and down when the second toothed wheel rotates. The inertial forces of the piston carrying out the up and down movement are compensated by a counterweight which is embodied in an integral manner with the second toothed wheel and is fixedly connected thereof.

Abstract: Vehicle pneumatic tire includes a carcass having sidewalls and a tread rubber. A sidewall area is covered on an outside by a sidewall rubber strip. A moiré pattern is arranged on the sidewall rubber strip and is formed by a superimposition of at least two linear non-identical families of curves. A first family of curves of the at least two linear non-identical families of curves is formed by undulatory curves having regular wave form. A second family of curves of the at least two linear non-identical families of curves is formed by undulatory curves having irregular wave form. This abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
