Abstract
Einspannvorrichtung zur Reifenmontage von Kraftfahrzeugrädern, mit einem in die Felgenöffnung eingreifenden, mittels eines Spannbolzens mit der Radfelge verspannten Zentrierkonus, dadurch gekennzeichnet, dass der Zentrierkonus (3) aus einem einstückigen Kunststoffteil aus Polyoxymethylen besteht.Clamping device for tire assembly of motor vehicle wheels, with an engaging in the rim opening, clamped by a clamping bolt with the wheel rim centering cone, characterized in that the centering cone (3) consists of a one-piece plastic part made of polyoxymethylene.
Description
Die Erfindung bezieht sich auf eine Einspannvorrichtung zur Reifenmontage von Kraftfahrzeugrädern, mit einem in die Felgenöffnung eingreifenden, mittels eines Spannbolzens mit der Radfelge verspannten Zentrierkonus, nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a clamping device for tire mounting of motor vehicle wheels, with one in the rim opening engaging, clamped by a clamping bolt with the wheel rim Centering cone, according to the preamble of claim 1.

Aufgabe der Erfindung ist es, eine Einspannvorrichtung der eingangs genannten Art zu schaffen, welche eine deutlich erhöhte Dauerstandfestigkeit besitzt und dennoch das eingespannte Fahrzeugrad sicher gegen Beschädigungen, insbesondere die erwähnten Druckspuren, schützt.task The invention is a clamping device of the aforementioned To create type, which has a significantly increased creep strength and yet the clamped vehicle wheel safe against damage, especially those mentioned Pressure marks, protects.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 gekennzeichnete Einspannvorrichtung gelöst.These The object is achieved by the in claim 1 characterized jig solved.
Aufgrund der besonderen Gestaltung des Zentrierkonus als einstückig massives Kunststoffteil mit den spezifischen Materialeigenschaften von Polyoxymethylen oder einem Kunststoff mit hinsichtlich Zugfestigkeit, E-Modul, Reibungskoeffizient und Abriebfestigkeit ähnlichen Kennwerten wird erfindungsgemäß eine Einspannvorrichtung geschaffen, welche selbst unter den rauen Betriebsbedingungen einer serienmäßigen Reifenmontage einschließlich des Auswuchtens von Kraftfahrzeugrädern über lange Einsatzzeiten voll funktionsfähig bleibt, ohne dass im Einspannbereich Druckspuren oder ähnliche Schadstellen an der Radfelge entstehen, auch wenn diese aus Aluminium oder einem anderen, vergleichsweise weichen metallischen Werkstoff hergestellt ist. Dementsprechend hat sich die erfindungsgemäße Einspannvorrichtung bei der praktischen Erprobung als äußerst verschleißfest, montagefreundlich und dauerhaft einspannsicher und bauteilschonend erwiesen.by virtue of the special design of the centering cone as an integral massive Plastic part with the specific material properties of polyoxymethylene or a plastic with respect to tensile strength, Young's modulus, coefficient of friction and abrasion resistance similar Characteristics according to the invention is a clamping device created even under the harsh operating conditions of a standard tire assembly including the balancing of motor vehicle wheels over long periods of use functioning remains, without that in the clamping area pressure marks or similar Damage to the wheel rim occurs, even if it is made of aluminum or another, comparatively soft metallic material is made. Accordingly, the clamping device according to the invention in practical testing as extremely wear-resistant, easy to assemble and permanently secure against jamming and component protection.
Die Erfindung wird nunmehr anhand eines Ausführungsbeispiels in Verbindung mit den Zeichnungen näher erläutert. Es zeigen in stark schematisierter Darstellung:The Invention will now be based on an embodiment in conjunction closer with the drawings explained. It shows in a highly schematic representation:
Die
in den Fign. dargestellte Einspannvorrichtung dient zum Festspannen
und Zentrieren eines in üblicher
Weise mit einer zentralen Felgenöffnung
Der
Zentrierkonus
Die
beschriebene Einspannvorrichtung wurde in der Praxis in Verbindung
mit der Reifenmontage an Aluminium-Radfelgen
In weiterer, baulich und montagemäßig bevorzugter Ausgestaltung der Erfindung ist zwischen Spannbolzen und Zentrierkonus ein aus dem gleichen Kunststoff wie der Zentrierkonus bestehendes und einteilig an diesen angeformtes Zwischenstück angeordnet.In further, structurally and montagemäßig preferred Embodiment of the invention is between clamping bolt and centering cone one consisting of the same plastic as the centering cone and arranged in one piece on this molded intermediate piece.
