Definitions
- the invention relates to a method for producing sound absorbers for vehicle tires and their material composition.
- the sound absorbers serve as sound absorbers that can be used or retrofitted for vehicle tires, which can be adapted to tires of different vehicles using simple means and an efficient method.
- the conveying device serves to convey the band-shaped sound absorber to a tire inner side of a tire by means of a feeding section for feeding the band-shaped sound absorber into a conveying section.
- the conveying section is designed to convey the belt-shaped sound absorber from an upper opening through which the belt-shaped sound absorber can be received via the feeding section to a lower opening through which the belt-shaped sound absorber can be discharged, whereby in the conveying section a rotatable core is arranged.
- Flanks protruding therefrom are formed on a surface of the rotatable core, and the core is rotated about an axis of rotation by a drive.
- the flanks run helically on the surface of the core.
- a band-shaped sound absorber fed via the feed section is wound up onto the core, limited laterally by the flanks.
- the strip-shaped sound absorber wound onto the core is conveyed in a conveying direction when the core is twisted.
- the band-shaped sound absorber conveyed in this way is thus guided from the conveying section via a discharge section to an assembly area.
- the sound shielding element has at least one plate or layer in an adjacent room and/or for covering sound-reflecting or sound-generating components. This has a large number of very small openings.
- the plate thickness or layer thickness is between 0.01 and 50 mm, the average diameter or the width of the openings is between 0.001 and 2 mm and the hole area ratio is between 0.001 and 20%.
- This sound shielding element takes up little space and is easy to produce and can be attached to many places in the car.
- it is disadvantageous that attachment in the immediate vicinity of the noise-acoustic source of interference caused by tire noise is not possible.
- the attachment of the sound shielding element is complex and the application is limited to its respective physical training.
- a vehicle tire which has a ring of material bonded inside it to the inner surface opposite the tread.
- the ring of material adheres to a self-sealing sealant. At least immediately after it has been applied, this sealant has the tack required for the material ring to adhere.
- the sealant which also serves as an adhesive, is applied after the tire has been heated, ie immediately during the manufacturing process. It is therefore not possible to retrofit the soundproofing measures on tires that have already been completed. Another disadvantage of this solution is the use of environmentally harmful foams.
- a sound absorbing element for a wheel of a vehicle or motor vehicle with a gas-filled cavity arranged between the rim and the tire Is known from the prior art after WO 2020/207915 A1 a sound absorbing element for a wheel of a vehicle or motor vehicle with a gas-filled cavity arranged between the rim and the tire.
- a ring-shaped base body made of textile material designed for this purpose is applied flat to the base of the rim. Extensions are arranged on an outer side of the base body and protrude into the cavity at least when the wheel is rotating at a sufficiently high speed.
- the sound-damping element has the property of damping the structure-borne noise emitted by the rim and the noise propagating outside of the cavity. The noise emission of the wheel is reduced in this way and the mechanical stress on the rim and/or the tire is prevented as far as possible.
- the complicated structure of the soundproofing element and the limitation of the application to its respective intended physical structure there are also disadvantages in this solution, the complicated structure of the soundproofing element and
- the noise-suppressing body is fixed to a tire-side cavity surface and is also covered by a waterproof protective member.
- the noise-suppressing body has a volume that is 0.4 to 20% of the entire volume of the tire cavity and is formed of sponge material. This sponge material extends in the circumferential direction and is installed in the tire inner cavity formed by the tire and the rim.
- the sound-suppressing body consists of a tire-side sound-suppressing body having a bottom surface fixed to the tire or a rim-side sound-suppressing body having a bottom surface fixed to the rim.
- the areal gravity of the tire-side sound-suppressing body or the centroid of area weight point of a sound-suppressing body main part is set in a predetermined range by the sound-suppressing body.
- Adhesive coated with peeling paper is applied to the underside of the noise-cancelling body.
- a disadvantage of this arrangement is the limitation of use to the point in time of the assembly process in the manufacture of commercial tires.
- This solution is unsuitable for sound-absorbing retrofits on tires with different dimensions using renewable raw materials as sound absorbers.
- the object of the invention is therefore to create a sound absorber for vehicle tires that can be used or retrofitted, which is composed of environmentally friendly materials, can be combined with other sound-suppressing materials by means of a fixed connection before assembly and can be combined with one another by means of an efficient process in terms of shape, size and properties Tires of different vehicles can be adjusted.
- the material surfaces of the noise-suppressing body are efficiently designed to be self-adhesive and provided with removable protective films, and when the tires are retrofitted, the materials are joined together in layers and/or next to one another by producing adhesive bonds.
- the method proves to be advantageous if at least one of the materials to be connected to one another from renewable raw materials in layers and/or next to one another consists of hemp fibers. Depending on the availability of the raw materials, it is also advantageous if at least one of the materials to be connected to one another from renewable raw materials in layers and/or next to one another is made of biological polyester.
- the use of the method for a wide-ranging adaptation to tires of different dimensions becomes effective when materials of the same type or selected for different sound-suppressing properties are combined to achieve the specified soundproofing and are adhesively bonded to one another in layers and/or next to one another.
- renewable raw materials are used as materials, the surfaces of which are designed in such a way that they can be adhesively bonded to one another.
- the materials of the sound absorber are designed in the form of strips, which is economically effective in terms of handling and the cost of materials, and the surfaces on the top and bottom of the strip are provided with self-adhesive properties.
- a wide range of applications for using the sound absorber on tires with different dimensions is effectively achieved if the sound absorber is adhesively bonded together in layers from at least two band-shaped materials each having different or the same sound-insulating properties.
- a quick and easy retrofitting of the differently dimensioned tires with the sound absorbers that can be assembled from the individual materials is efficiently achieved if at least two band-shaped materials each having different or the same sound-insulating properties are adhesively joined next to one another on a base body.
- a design of the sound absorber that is advantageous for the retrofitting process is achieved by the band-shaped materials having different or similar sound-insulating properties being applied to supply rolls, the respective upper and lower sides of which are designed to be self-adhesive and provided with a removable protective film, the required sound-insulating effect being achieved by the layered and/or adjacent adhesive arrangement of the selected materials Body is formed, which corresponds to the respectively specified sound insulation properties of the tires.
- the representation of figure 1 shows an embodiment of the sound absorber in the form of a strip.
- a surface section with a non-adhesive surface 1 and a surface section with a self-adhesive surface 2 are reproduced in the partial schematic representation of the tape on one of the surfaces running along the tape.
- a protective film 3 partially peeled off the surface of the tape.
- the section of non-stick surface 1 shown serves as a work surface when retrofitting the tires.
- Renewable raw materials are used as the material for the sound absorber. These can be made of hemp fibers or biological polyester, for example. In the specific embodiment, these materials can be designed as polyester nonwovens.
- the band-shaped sound absorbers can each be formed with self-adhesive surfaces 2 on the top and bottom.
- One of the self-adhesive surfaces 2 is used for tire-side attachment and the other self-adhesive surface 2 is used for adhesive connection with other sound absorbers made of the same materials or different materials.
- the schematic representation of figure 2 shows two prepared sections of the band-shaped sound absorber, which are connected to one another in order to achieve a predetermined sound-damping effect adapted to the tire.
- the self-adhesive surfaces of the first strip section 5 and the second strip section 4 are used for the connection to one another.
- One of the outwardly facing surfaces of the combination of the band sections 4, 5 is used to create the connection with the rim inside the tire cavity.
- the removable protective films 3 applied to the top and bottom of the respective band-shaped sound absorber serve to protect the adhesive surfaces applied to the band surfaces.
- the figure 3 shows a possible combination of several sound absorbers made from the same and/or different sound-absorbing materials.
- several sound absorbers divided into band sections 4, 5, 6, 7 were adhesively connected to one another during retrofitting.
- the lowermost strip section 7 is adhesively connected to the rim and the further strip sections 4, 5 and 6 are adhesively applied to the strip section 7.
- the sound-damping materials used can alternatively have the same or different sound-damping values.
- the number and physical dimensions of the required sound absorbers depend on the soundproofing values to be achieved.
- the band-shaped sound-absorbing materials can be rolled up on a supply roll and cut into band sections during assembly preparation.
- the required strip sections are then adhesively connected to the rim next to one another and/or one above the other.

Nachteilig ist an dieser Anordnung die Nutzungsbeschränkung auf den Zeitpunkt des Montageablaufes bei der Herstellung kommerzieller Reifen. Für schalldämpfende Nachrüstungen an unterschiedlich dimensionierten Reifen unter Anwendung nachwachsender Rohstoffe als Schallabsorber ist diese Lösung ungeeignet.A disadvantage of this arrangement is the limitation of use to the point in time of the assembly process in the manufacture of commercial tires. This solution is unsuitable for sound-absorbing retrofits on tires with different dimensions using renewable raw materials as sound absorbers.
Die Aufgabe der Erfindung besteht deshalb in der Schaffung eines einsetzbaren bzw. nachrüstbaren Schallabsorbers für Fahrzeugreifen, der sich aus umweltschützenden Materialien zusammensetzt, vor der Montage mit weiteren schallunterdrückenden Materialien mittels einer feste Verbindung miteinander kombinierbar und mittels eines effizienten Verfahrens in Form, Größe und Eigenschaften an Reifen unterschiedlicher Fahrzeuge angepasst werden kann.The object of the invention is therefore to create a sound absorber for vehicle tires that can be used or retrofitted, which is composed of environmentally friendly materials, can be combined with other sound-suppressing materials by means of a fixed connection before assembly and can be combined with one another by means of an efficient process in terms of shape, size and properties Tires of different vehicles can be adjusted.
Gelöst wird diese Aufgabe mit dem geschaffenen Herstellungsverfahren zur Herstellung von Schallabsorbern an Reifen und den dazu gestalteten Schallabsorbern zur Durchführung des Verfahrens entsprechend den beschreibenden Merkmalen der Patentansprüche 1 und 4. Vorteilhafte Weiterbildungen des Verfahrens beschreiben die kennzeichnenden Merkmale der Patentansprüche 2 bis 5. Effiziente Weiterbildungen der Schallabsorber werden mit den kennzeichnenden Merkmalen der Patentansprüche 6 bis 9 beschrieben. Bei der Durchführung des Verfahrens kommen als Materialien für die Zusammensetzung des geräuschunterdrückenden Körpers nachwachsende Rohstoffe zur Anwendung, deren Oberflächen so beschaffen sind, dass sie mit den Oberflächen weiterer, gleichartige oder andere schallunterdrückende Eigenschaften aufweisender Materialien sowie gleichermaßen auch mit der reifenseitigen Hohlraumoberfläche verbunden werden können. Effizient werden die Materialoberflächen des geräuschunterdrückenden Körpers selbstklebend ausgebildet und mit abziehbaren Schutzfolien versehen sowie bei der Nachrüstung der Reifen die Materialien durch Herstellung von Klebeverbindungen schichtweise und/oder nebeneinanderliegend zusammengefügt. Vorteilhaft erweist sich das Verfahren, wenn mindestens eines der aus nachwachsenden Rohstoffen schichtweise und/oder nebeneinanderliegend miteinander zu verbindenden Materialien aus Hanffasern besteht. Je nach Vorhandensein der Rohstoffe ist es auch von Vorteil, wenn mindestens eines der aus nachwachsenden Rohstoffen schichtweise und/oder nebeneinanderliegend miteinander zu verbindenden Materialien aus biologischem Polyester hergestellt sind. Die Nutzung des Verfahrens für eine breit angelegte Anpassung an unterschiedlich dimensionierte Reifen wird dadurch effektvoll, wenn gleichartige oder nach unterschiedliche schallunterdrückende Eigenschaften ausgewählte Materialien zwecks Erzielung der vorgegebenen Schalldämpfung kombiniert zusammengestellt sowie schichtweise und/oder nebeneinanderliegend klebend miteinander verbunden werden. Für einen effizienten Aufbau der für das Verfahren geschaffenen Schallabsorber kommen als Materialien nachwachsende Rohstoffe zur Anwendung, deren Oberflächen derart ausgebildet sind, dass sie miteinander haftend verbunden werden können. Wirtschaftlich effektiv hinsichtlich der Handhabung und des Materialaufwandes werden die Materialien des Schallabsorbers bandförmig ausgebildet und die auf der Ober- und Unterseite des Bandes befindlichen Oberflächen mit selbstklebenden Eigenschaften versehen. Eine breite Anwendungspalette für die Nutzung der Schallabsorber an unterschiedlich dimensionierten Reifen wird effektvoll dadurch erreicht, wenn der Schallabsorber aus mindestens zwei bandförmig ausgebildete und jeweils unterschiedliche oder gleiche schalldämmende Eigenschaften aufweisende Materialien haftend schichtweise zusammengefügt ist. Eine schnelle und einfache Nachrüstung der unterschiedlich dimensionierten Reifen mit den aus den einzelnen Materialien zusammenstellbaren Schallabsorbern wird effizient erreicht, wenn mindestens zwei bandförmig ausgebildete und jeweils unterschiedliche oder gleiche schalldämmende Eigenschaften aufweisende Materialien auf einem Grundkörper haftend nebeneinanderliegend zusammengefügt werden. Eine für das Nachrüstverfahren vorteilhafte Gestaltung der Schallabsorber wird erreicht, indem die unterschiedliche oder gleichartige schalldämmende Eigenschaften aufweisenden bandförmigen Materialien auf Vorratsrollen aufgebracht sind, deren jeweilige Ober- und Unterseiten selbstklebend ausgebildet und mit einer abziehbaren Schutzfolie versehen sind, wobei durch die hergestellte schichtweise und/oder nebeneinanderliegende haftende Anordnung der ausgewählten Materialien der erforderliche geräuschdämmende Körper gebildet wird, der den jeweilig vorgegebenen Schalldämmeigenschaften der Reifen entspricht.This problem is solved with the created production method for the production of sound absorbers on tires and the designed sound absorbers for carrying out the method according to the characterizing features of
