Abstract
Description
Felge für luftbereifte Fahrzeugräder Die Erfindung betrifft eine Tiefbettfelge für luftbereifte Fahrzeugräder, die in üblicher Weise so ausgebildet ist, daß das Tiefbett während der Montage des Luftreifens imstande ist, einen Reifenwulst aufzunehmen.Rim for vehicle wheels with pneumatic tires The invention relates to a drop center rim for pneumatic vehicle wheels, which is designed in the usual way so that the Deep bed is able to accommodate a tire bead during assembly of the pneumatic tire.
Eine so ausgeführte Felge bringt zwar den Vorteil einer erleichterten Montage mit sich, sie hat aber den Nachteil, daß der zwischen den Felgensitzflächen befindliche Teil nicht mehr als Notlaufanschlag für den defekt gewordenen Luftreifen verwendet werden kann.A rim designed in this way has the advantage of a lightened one Assembly with itself, but it has the disadvantage that between the rim seat surfaces The part located no longer acts as an emergency stop for the defective pneumatic tire can be used.
Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, die eingangs genannte Tiefbettfelge so zu verbessern, daß der Felgenkörper Notlaufeigenschaften vermittelt bzw. als Widerlager bei vergleichsweise großen auf den Reifenkörper einwirkenden Radialkräften dienen kann.The invention is essentially based on the object to improve called drop center rim so that the rim body emergency running properties mediated or as an abutment with comparatively large acting on the tire body Can serve radial forces.
Zuribsung dieser Aufgabe erhält erfindungsgemäß die Felge in dem zwischen den beiden Felgensitzflächen befindlichen Teil einen etwa W-förmigen Querschnitt.According to the invention, the rim receives this object in the between the part located on the two rim seat surfaces has an approximately W-shaped cross section.
Diese Querschnittsform hat einerseits einen mittig angeordneten Vorsprung zur Folga,em anderen zu beiden Seiten dieses Vorsprungs tiefbettartige Vertiefungen, die die Reifenwülste zum Zwecke der Erleichterung der Reif enmontage aufnehmen können, wobei es sich versteht, daß der mittig angeordnete Vorsprung V-förmigaaber auch abgerundet, gegebenenfalls aber auch mit einer elastischen Deckschicht versehen sein kann.On the one hand, this cross-sectional shape has a centrally arranged projection to follow, on the other, deep-bed-like depressions on both sides of this projection, which can accommodate the tire beads to facilitate tire fitting, it goes without saying that the centrally located projection V-shaped but also rounded, but optionally also provided with an elastic cover layer can be.
Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein vorzugsweise zur Anwendung kommendes Ausführungsbeispiel dargestellt ist.Further details of the invention are explained with reference to the drawing, in which an exemplary embodiment that is preferably used is shown is.
Die Abb. zeigt einen radialen Teilschnitt durch ein Fahrzeugrad. The illustration shows a partial radial section through a vehicle wheel.
Die in bekannter Weise aus Metall bestehende Felge 1 hat im Bereich ihrer beiden seitlichen etwa zylindrischen Ränder 2 die Sitzflächen 3i 4 für die Reifenwülste 5 eines im Betriebszustand nahezu zy7indrischen, schwach ballig ausgewölbten Luftreifens 6 mit Laufstreifen 7, der sich mittig zwischen den beiden Wülsten 5 befindet.The rim 1, which is made of metal in a known manner, has in the area its two lateral approximately cylindrical edges 2, the seats 3i 4 for the Tire beads 5 of an almost cylindrical, slightly convex arched shape in the operating state Pneumatic tire 6 with tread 7, which is centered between the two beads 5 is located.
Zwischen den beiden Rändern 2 ist die Felge 1 W-förmig gestaltet.Between the two edges 2, the rim 1 is designed in a W-shape.
und zwar so, daß die beiden außen liegenden Schenkel 8 den W sich von den Sitzflächen 4 aus gesehen nach innen auf die Drehachse der Felge erstrecken. An die beiden Schenkel 8 schließen sich nach innen hin trapezförmige Umfangsvertiefungen 9 an, zwischen denen die Felge an ihrem äußeren Umfang bei 10 etwa zylindrisch ausgeführt ist. insgesamt gesehen ergibt sich somit zwischen den beiden Händern 2 eine W-Form, wobei die axiale Erstreckung der beiden Umfangsvertiefungen 9 etwa der axialen Breite des Mittelteils bei 10 entlspricht.in such a way that the two outer legs 8 the W itself extending inwardly from the seat surfaces 4 onto the axis of rotation of the rim. Trapezoidal circumferential depressions close towards the inside on the two legs 8 9, between which the rim is approximately cylindrical on its outer circumference at 10 is. viewed overall, there is thus a W-shape between the two hands 2, wherein the axial extent of the two circumferential depressions 9 is approximately the axial width of the middle part at 10 corresponds.
Während die Vertiefungen 9 je in der Lage sind, einen Wulst 5 aufzunehmen, wenn der Reifen montiert werden soll, kann der zylindrische Mittelabschnitt 10 als Widerlager dienen, wenn bei vergleichsweise hohen Radialkräften der Reifenkörper durchfedern muß. Er findet dann im Mittelteil bei 10 eine Anlage, die durch elastische Deckschichten auf der Felge 1 elastisch nachgiebig gestaltet sein kann.While the depressions 9 are each able to accommodate a bead 5, when the tire is to be mounted, the cylindrical central portion 10 can be used as Abutments are used when the tire body is exposed to comparatively high radial forces must spring through. He then finds in the middle part at 10 a plant that is elastic Cover layers on the rim 1 can be designed to be elastically resilient.
Das Mittelteil bei 110 befindet sich auf einem Durchmesser, der kleiner ist als der Durchmesser, auf dem sich die Sitzflächen 4 befinden, um so bei der etwa zylindrischen Gestalt des Reifenkörpers ausreichend große Federwege zustande kommen zu lassenThe middle part at 110 is on a diameter that is smaller is than the diameter on which the seat surfaces 4 are located, so as in the approximately cylindrical shape of the tire body sufficiently large spring travel to let come
