Description

Schraubensicherung für Kraftfahrzeugräder Die Erfindung bezieht sich auf eine Schraubensicherung für Kraftfahrzeugräder.Screw locking for motor vehicle wheels The invention relates on a screw locking device for motor vehicle wheels.

Die bekannten Verschraubungen, die zum Befestigen von Kraftfahrzeugrädern verwendet werden, sind meistens mit Kronenmuttern ver. sehen, die durch Splinte gesichert sind. Bei Verwendung ,solcher Schrauben entsteht infolge der Durchbohrung für den Splint eine Schwächung. Werden Spezialschrauben verwendet, so erfordert deren Herstellung einen besonders großen Aufwand an Arbeitszeit und Kosten. Auch das Anbringen und Läsen der Verschraubung erfordert infolge der Anwendung eines Splintes verhältnismäßig viel Zeit.The known screw connections for fastening motor vehicle wheels used are mostly provided with castle nuts, which see through split pins are secured. When using such screws is created as a result of the cannulation a weakening for the splint. If special screws are used, this is required their production requires a particularly large amount of time and money. Even the attachment and loosening of the screw connection requires as a result of the application of a Splintes a relatively long time.

Es sind auch bereits Verschraubungen mit Gegenmutter verwendet worden, doch haben sich diese nicht als genügend zuverlässig erwiesen.Screw connections with lock nuts have also already been used, but these have not proven to be sufficiently reliable.

Um diese Nachteile zu vermeiden,;sinderfindungsgemäß die Muttern, die in an sich bekannter Weise außen kegelig ausgebildet sind, um sich in die kegelig erweiterten Schraubenlöcher der Radwand einlegen zu können, durch eine Gegenmutter gesichert, die im unteren Teil geschlitzt und k egelig ausgebildet ist, so daß sie sich .beim Anziehen und beim Einlegen in eine :entsprechende kegelige Ausnehmung der unteren Mutter fest .an den Bolzen anlegt.In order to avoid these disadvantages; according to the invention, the nuts, which are designed to be conical on the outside in a known manner in order to be conical to be able to insert enlarged screw holes of the wheel wall by means of a lock nut secured, which is slotted and tapered in the lower part, so that they when tightening and when inserting into a: corresponding conical recess the lower nut tightly on the bolt.

Schraubensicherungen aus einer unteren Mutter und einer oberen Mutter, von denen sich die letztere mit einem kegeligen geschlitzten Unterteil iai eine entsprechend kegelige Ausnehmung der unteren Mutter einlegt, sind an sich bekannt.Screw locking from a lower nut and an upper nut, of which the latter has a conical slotted lower part iai one correspondingly conical recess of the lower nut inserts are known per se.

Der Erfindungsgegenstandistauf der Zeichnung beispielsweise dargestellt, und zwar in Abb. z vor dem Anziehen der Obermutter und in Abb. a nach dem Anziehen (beide Ausbildungen in Senkr.ech.tschnitt des Oberteils der Untermutter und der Radwand).The subject of the invention is shown in the drawing, for example, in Fig. z before tightening the upper nut and in Fig. a after tightening (Both trainings in vertical vertical section of the upper part of the lower nut and the Wheel wall).

Die Verschraubung wird gebildet aus der Obermuttera mit mehrfach geschlitztem unteren Außenkonusteil b und der Untermutter mit oberem Innenkonusteil i und einem unteren steilwandigen Außenkonustell jL, der sich in bekarmter Weise in die kegelig erweiterten Schraubenlöcher der Radwände einlegt.The screw connection is formed from the upper nut with multiple slits lower outer cone part b and the lower nut with upper inner cone part i and one lower steep-walled Außenkonustell jL, which is in a well-known manner in the conical Inserted enlarged screw holes of the wheel walls.
