Definitions
- the invention relates to a vehicle wheel compared to a conventional
- Vehicle wheel generates much lower running noise.
- the invention further relates to a method for filling the tire interior in order to design a conventional vehicle wheel according to the invention.
- the tubeless tire is placed on a rim with special devices in such a way that the radially circumferential bead of the tire lies against the inside of a rim shoulder arranged on the periphery of the rim and a toroidal tire interior enclosed by the tire and the rim is formed.
- the interior of the tire can be filled with a filling gas, usually compressed air, via a valve arranged on the rim.
- the filling pressure is an essential parameter for the running properties of the vehicle wheel.
- the invention has for its object to develop a vehicle wheel according to the preamble of claim 1 in such a way that the running noise of the vehicle wheel is significantly reduced and to provide a method with which the inventive development can be implemented in a simple manner on a conventional vehicle wheel.
- the invention is based on the knowledge that the tire interior of a vehicle wheel represents a resonance space which significantly amplifies the running noises which emanate essentially from noise sources to be located on the tread.
- the invention is further based on the finding that driving noise can be significantly reduced if the resonance effect of the tire interior is eliminated or at least substantially reduced by filling it with a sound-absorbing filler.
- the interior of the tire is filled in a known manner with a filling gas under pressure, in particular compressed air.
- the filling material must have a granular consistency that adapts to the deformation of the tire and must not be sharp-edged so as not to damage the inner skin of the tire.
- the filling material In order to ensure the long-term stability of the filling material, the filling material must remain dimensionally stable under the flexing movement of the tire and must also be resistant to the temperature increase of the tire which occurs at high driving speeds.
- Claims 2 to 14 relate to advantageous developments of the vehicle wheel according to the invention.
- the filler material can essentially completely fill the tire interior.
- a valve system designed in accordance with claims 4 to 6 can be provided for simultaneously filling the tire interior with the filling material and the filling gas. Furthermore, it is conceivable to provide two separate filling chambers for the granular filling material and the filling gas in the tire interior.
- the filling material in addition to a high Sound absorption value has a largely homogeneous grain size of small diameter and is flame retardant.
- Foamable plastic materials in particular polystyrene, are particularly suitable as filling material.
- the inflation gas After mixing the tire inflation gas with the granular filling material, the inflation gas is optionally. compressed and the mixture of filling material and filling gas blown into the tire interior.
- Claims 15 and 16 relate to advantageous developments of the method according to the invention.
- a foamable plastic material is used as the filling material, a corresponding step for foaming the plastic material according to claim 16 can precede the method according to claim 14.
- FIG. 1 shows in section a first exemplary embodiment of a peripheral portion of the vehicle wheel according to the invention
- FIG. 2 shows in section a second exemplary embodiment of a peripheral section of the vehicle wheel according to the invention
- FIGS. 1 and 2 shows a partial enlargement of a partial area of FIGS. 1 and 2;
- FIG. 4A and B a schematic representation of a valve arrangement according to the invention for filling the tire interior.
- Fig. 1 shows a first embodiment of the vehicle wheel according to the invention.
- a rim 1 has in its peripheral area a rim shoulder 2 which extends essentially in the axial direction and which connects to the spoke-like connecting parts 3 Axle of the vehicle wheel, not shown, is connected.
- the rim shoulder 2 has two radially encircling rim flanges 4 and 5, on which it is connected to the bead 11, 12 of a tire 10.
- the bead 11, 12 of the tire 10 can have a reinforcement in the form of a bead core 13, 14.
- the rubber coating of the tire has tread-like depressions 16 on the tread 15.
- the rim shoulder 2 and the tire 10 enclose a gas-tight inner space 6 which can be filled with a filling gas, in particular compressed air, via a valve 7 in the rim 1.
- the inflation pressure prevailing in the inner space 6 is a tire-specific parameter which essentially determines the running properties of the tire.
- the tire interior 6 is essentially completely filled with a granular, dimensionally and temperature-resistant filler material in accordance with the first exemplary embodiment of the invention shown in FIG. 1.
- the filling material has a substantially greater sound absorption, so that the tire interior 6 is acoustically damped and its resonance effect is eliminated or at least substantially reduced.
- the interior of the tire 6 is filled with a filling gas, in particular compressed air, so that the static and dynamic properties of the tire do not change, but at most are insignificant, compared to conventional filling with compressed air. Driving comfort is therefore not restricted in any way by the filling material.
- the granular consistency of the filling material which is essential to the invention, ensures that the filling material becomes the
- filling the interior of the tire with a granular filling material has the advantage that the filling material is not decomposed by the flexing work of the tire, but the flexing work of the tire only causes a redistribution of the filling material at most .
- the filling material used is dimensionally and temperature-resistant even under prolonged use.
- the dimensional stability can be achieved in particular by using an elastically deformable material.
- the temperature resistance is essential due to the temperature increase of the tire at a high vehicle speed.
- the joining material has a high sound absorption value, so that the resonance damping of the tire interior is particularly effective.
- the filler material used has a largely homogeneous grain size of small diameter.
- the filling material can in particular be spherical with a diameter of less than 1 mm.
- the inflation gas can distribute itself evenly in the tire interior 6 and thus exerts a uniform pressure on the wall of the tire.
- the filling material must therefore not hinder the flow of the filling gas as a result of the deformation of the tire caused by the flexing movement. Therefore the grain size of the filling material must not be too small.
- the filling material essentially completely fills the tire interior 6 in the exemplary embodiment according to FIG. 1.
- the volume fraction of the filling material is preferably more than 90%.
- the exemplary embodiment shown in FIG. 2 shows a second exemplary embodiment of the vehicle wheel according to the invention.
- the exemplary embodiment shown in FIG. 2 has two toroidal filling chambers 6a, 6b in the tire interior.
- One of them, here the filling chamber 6b arranged on the side of the support surface 15, is essentially completely filled with the granular filling material already described, while the other filling chamber 6a arranged on the axis side is only filled with a filling gas, in particular compressed air.
- the two filling chambers 6a and 6b are separated by a membrane-like partition 8.
- the membrane-like partition 8 ensures pressure equalization between the two filling chambers 6a and 6b.
- the embodiment shown in FIG. 2 improves the deformability of the tire during the flexing movement thereof. Furthermore, the filling material can be introduced into the chamber 6b when the tire is being produced and remains in it even when the tire is changed.
- the chamber filled with the filling material can also be provided on the rim side.
- the area 9 of the tire interior 6 or the filling chamber 6b is shown enlarged in sections.
- the individual particles 20 of the granular filling material can be seen.
- the particles of the filling material are advantageously arranged in high density, so that the tire interior 6 or the filling chamber 6b is almost completely filled with the particles.
- the intermediate volumes 21 formed between the particles 20 of the filling material can be flowed through by the filling gas.
- an elastically deformable plastic material of low density is particularly suitable as filler material.
- a foamable plastic material e.g. Polystyrene under the
- Trademark Styrofoam ⁇ is distributed. If necessary, addition of other plastic components besides polystyrene can also be used. Pentane or another hydrocarbon gas can be used as the blowing agent. If polystyrene is used as the filling material, a bulk density of 20 to 40 kg / m ⁇ can be achieved. Foamable plastic materials have the advantage that the grain size of the filling material can be influenced within wide limits by the foaming process and a relatively homogeneous grain size is obtained.
- the filling chamber 6a is filled with the filling gas in a known manner via a valve 7 arranged on the rim 1.
- the pressure regulation of the filling gas to be introduced into the tire interior 6 next to the filling material of the one shown in FIG. 1 Vehicle wheel can also be done via a conventional valve 7.
- the tire interior 6 can advantageously be filled simultaneously with the filling material and with the filling gas.
- the basic principle of a valve arrangement required for this is shown chemically with reference to FIGS. 4A and 4B.
- a fill valve 30 and a pressure regulating valve 31 are let into the rim 2.
- the filling valve 30 is closed in the idle state by means of a spring 32.
- the inflation pressure of the tire interior 6 acts on the closing element 33
- Pressure regulating valve 31 is also closed by a closure element 35 which is pressed against the wall of the rim 2 in the idle state by means of a spring 34.
- the pressure of the tire interior also acts on the closure element 35.
- the closure element 35 can be opened via a dome 36.
- the filling valve 30 is designed in such a way that the particles 20 of the filling material can enter the tire interior 6 through its cross section, that is Pressure regulating valve 31 is designed only for filling or emptying the filling gas of the tire interior.
- the particles of the filling material are held by the pressure regulating valve 31 by a sieving device 37.
- FIG. 4B shows the valve arrangement described with reference to FIG. 4A during the
- the filling valve 30 After mixing the tire inflation gas with the granular filling material, the mixture reaches the filling valve 30 via a delivery hose 38.
- the pressure of the filling gas opens the closure element 33 of the filling valve 30 and the filling gas, together with the particles 20 of the filling material, reaches the filling valve
- the pressure regulating valve 31 is used for this purpose. Pressure on the dome 36 allows the closure element 35 of the pressure regulating valve 31 to be opened and the excess filling gas to escape.
- the sieving device 37 prevents the particles 20 of the filling material from escaping. During the filling process, the density of the particles of the filling material in the tire interior 6 thus increases.
- the desired pressure of the filling gas can be set via the pressure regulating valve 31.
- the pressure regulating valve 31 can also be operated in such a way that it only opens when the desired filling pressure of the filling gas has been exceeded.
- valve arrangement shown in FIGS. 4A and 4B is only to be understood schematically. The actual, technical embodiments can differ considerably from the illustration.
- the filling valve 30 and the pressure regulating valve 31 can be constructed in a structural unit, in particular coaxially or axially parallel. his.
- the method for filling the tire interior can be preceded by a known method for foaming the plastic material when using a foamable plastic material as the filler material. It is useful when Foaming to remove any by-products that may arise (eg water) before filling (eg by drying).
- the filling material can be easily recycled or reused after appropriate cleaning.
- the solution according to the invention is not only suitable for vehicle wheels with tires, but is suitable for significantly reducing the running noise of vehicles of all kinds, in particular also of rail vehicles.
- the rail body and the sleeper body can also be filled.
