Abstract
Description
Beschreibungdescription
Die Erfindung betrifft eine Scheibenbremse für ein Rad eines Fahrzeugs, insbesondere Schwerlastkraftwagen oder Omnibus, mit Merkmalen entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a disc brake for a wheel a vehicle, especially heavy goods vehicles or buses, with features corresponding to the preamble of claim 1.
Bei herkömmlichen Scheibenbremsen besteht das Problem, durch die Verbindung Radnabe/Bremsscheibe in Form eines angegossenen Topfes starke Ausdehnungsbehinderungen bei Erwärmung der Bremsscheibe gegeben sind, was z. B. zu welligen Bremsflächen führt. Eine Besserung dieses Problems tritt durch eine Trennung von Bremsscheibe und Nabe über eine radial freie Welle-Nabe-, z. B. Nut-Feder-Verbindung, ein. Ein sicherer Verbund zwischen der Radnabe und der Bremsscheibe besteht in der Regel dann, wenn diese kalt oder nur mäßig erwärmt ist. Sobald sich jedoch die Bremsscheibe stark erhitzt, entsteht eine Dehnungsfuge zwischen Radnabe und Bremsscheibe, was zu einem rotatorischen Flattern der Bremsscheibe und einer Erhöhnung des Schallpegels aufgrund des oszillierenden Anschlagens der dann etwas voneinander beabstandeten Formschlussorgane führt.With conventional disc brakes the problem by connecting the wheel hub / brake disc in the form of a cast pot strong expansion constraints when the Brake disc are given what z. B. leads to wavy braking surfaces. A This problem improves by separating the brake disc and hub over a radially free shaft-hub, e.g. B. tongue and groove connection. There is a secure bond between the wheel hub and the brake disc usually when it is cold or only moderately warmed. However, as soon as the brake disc is very hot, there is an expansion joint between the wheel hub and brake disc, causing the brake disc to flutter rotationally and an increase of the sound level due to the oscillating striking of the then slightly spaced form-locking organs leads.
Es ist demgegenüber daher Aufgabe der Erfindung, eine Scheibenbremse zu schaffen, bei der mit einfachen und kostengünstigen Mitteln ein sicherer Verbund der Bremsscheibe auch dann, wenn diese stark erhitzt ist, mit der Radnabe gewährleistet ist.In contrast, it is therefore an object of the invention to create a disc brake with simple and inexpensive Averaging a secure bond of the brake disc even if this is strongly heated, with the wheel hub is guaranteed.
Diese Aufgabe ist bei einer Scheibenbremse erfindungsgemäß durch eine Konstruktion mit den im Kennzeichen des Anspruchs 1 angegebenen Merkmalen gelöst.This object is achieved according to the invention in a disc brake a construction with the specified in the characterizing part of claim 1 Features resolved.
Vorteilhafte Ausgestaltungen dieser Lösung sind in den Unteransprüchen angegeben.Advantageous embodiments of this Solution are in the subclaims specified.
Erfindungsgemäß sind in der zentralen Durchgangsbohrung der Bremsscheibe eine gleichmäßige Innenverzahnung und am Umfang der Radlager-Außenhülse eine entsprechend angepasste gleichmäßige Außenverzahnung gegeben, die so gefertigt sind, dass zwischen ihnen ein definierter Spalt verbleibt, in den ein Wellring aus Federstahl eingesetzt ist. Der Clou an dieser Erfindung ist, dass sich die Verzahnungen am Radlager und der Bremsscheibe im kalten Zustand praktisch spielfrei am Wellring abstützen, der Wellring sich aber bei starker Erwärmung, die durch eine entsprechend starke Erwärmung der Bremsscheibe initi iert wird, in Wellentäler der Verzahnungen hinein ausdehnen kann und so auch bei heißem Zustand der Bremsscheibe deren einwandfreier Sitz auf der Verzahnung am Radlager ohne das bisher auftretende Zahnklappern sichergestellt ist.According to the invention are in the central through hole the brake disc has a uniform internal toothing and on the circumference of the wheel bearing outer sleeve correspondingly adjusted uniform external teeth given that are made so that between them a defined Gap remains in which a corrugated ring made of spring steel is inserted. The highlight of this invention is that the teeth on Wheel bearings and the brake disc are virtually free of play when cold support on the corrugated ring, the corrugated ring, however, is exposed to strong heating caused by a corresponding strong warming the brake disc is initiated into the troughs of the gear teeth can expand and so even when the brake disc is hot their perfect fit on the toothing on the wheel bearing without that previously occurring tooth rattling is ensured.
Nachstehend ist die Erfindung anhand zweier in der Zeichnung dargestellter Ausführungsbeispiele noch näher erläutert. In der Zeichnung zeigen:The invention is illustrated below two embodiments shown in the drawing explained in more detail. In the drawing shows:
