Abstract

Friction plate and frustoconical elements in synchromesh gears are made of a material which has a high thermal conductivity, such as a low-alloyed Cu alloy, Cu-Zn alloy and high strength Al alloy. Pref. the friction plate is made of a Cu alloy type Cuzn40Al of compsn. 56.5-59.5% Cu, 0.4-1.6% Al, 0.4-1.8% Mn, balance zn, and the frusto-conical elements of type CuNi2si having the compsn. 1.6-2.5% Ni, 0.5-0.8% Si, balance Cu. Synchromesh gears incorporating these alloys have a longer life. The friction surfaces are not affected by microthermal processes which occur in synchromesh gears. The faces of the ring and cone retain their structure as overheating is avoided.

Description

Die Erfindung betrifft die Verbesserung von Synchronisations-The invention relates to the improvement of synchronization

einrichtungen von Getrieben.devices of gearboxes.

Es ist bekannt, eine Reibscheibe einer Synchronisiereinrichtung aus einer Bronzelegierung (DT-AS 1 630 912) oder einem Messing und das Gegenstück aus Stahl zu machen.It is known to make a friction disc of a synchronizer a bronze alloy (DT-AS 1 630 912) or a brass and the counterpart To make steel.

Die bekannten Synchronisiereinrichtungen haben sich in vielen Fällen bewährt. Durch die weseiitlich gestiegene Synchronisationsarbeit mancher Getriebe tritt aber bei der üblichen Paarung ein Versagen der Synchronisation ein. Dieses Versagen ist durch Glättung am Gegenstück aus Stahl (Stahlkonus), durch Abfall des Reibungskoeffizienten und damit Anstieg der Synchronisationszeit gekennzeichnet. Der Gleichlauf der Zahnkränze wird nicht mehr ordnungsgemäß erreicht, so daß es zu Geräuschentwicklung und Beschädigung des Getriebes kommt.The known synchronizers have proven themselves in many cases proven. Due to the significant increase in the synchronization work of some transmissions however, the synchronization fails with the usual pairing. This Failure is due to smoothing on the steel counterpart (steel cone), due to the falling off of the Coefficients of friction and thus increase in synchronization time. The synchronism of the sprockets is no longer achieved properly, so that it there is noise and damage to the gearbox.

Die Aufgabe der Erfindung besteht darin, für die im Reibschluß miteinander kuppelnden Teile solche Legierungen vorzuschlagen, daß die Wirkung der Synchronisationseinrichtung auch bei hoher und extremer Beanspruchung erhalten bleibt.The object of the invention is for those in frictional engagement with one another Coupling parts propose such alloys that the effect of the synchronization device is retained even under high and extreme stress.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Die darin genannten Legierungen sind durch die Deutschen Industrienormen, DIN 17 666, Tabelle 2 DIN 17 660, Tabelle 3 (nur Cu Zn 40 All und Cu Zn 40 Al 2) und DIN 1725, Blatt 1, Tabelle 1 (nur Al Zn Mg Cu 0,5 und Al Zn Mg Cu 1,5) mit DIN 1725, Blatt 2, Tabellen 1, 2 und 3 zwar bereits bekannt; auch ist es bereits bekannt, wie eingangs erwähnt, eine Reibscheibe aus einer Bronzelegierung herzustellen, Jedoch konnten diesen Fundstellen keine Anregung entnommen werden, die betreffenden Legierungen in der erfindungsgemäßen Weise zu verwenden.This object is achieved by the features of claim 1. The alloys named therein are certified by the German industrial standards, DIN 17 666, table 2 DIN 17 660, table 3 (only Cu Zn 40 All and Cu Zn 40 Al 2) and DIN 1725, sheet 1, table 1 (only Al Zn Mg Cu 0.5 and Al Zn Mg Cu 1.5) with DIN 1725, Sheet 2, Tables 1, 2 and 3 are already known; it is also already known As mentioned at the beginning, to produce a friction disk from a bronze alloy, however no suggestion could be derived from these sources, the alloys in question to be used in the manner according to the invention.

Erfindungsgemäß bleiben die Eigenschafto der Reibflächen einer Synchronisiereinrichtung durch mikrothermische Vorgänge unbeeinflußt erhalten und die funktionsgerechte Ubertragung der Schaltkräfte sind gewährleistet. Die miteinander reibenden Flächen von Synchronring und Gegenstück behalten ihre Struktur, da eine Uberhitzung der kontaktierenden Flächen wegen der die Wärme ableitenden, miteinander kuppelnden Teile nicht auftreten kann. Die obersten Schichten dieser Flächen können daher nicht erweichen und schmelzen, so daß die sogenannte Glättung unterbleibt und der Reibungskoeffizient die zur Synchronisation erforderliche Höhe beibehält.According to the invention, the properties of the friction surfaces of a synchronizing device remain preserved unaffected by microthermal processes and the functional transmission the switching forces are guaranteed. The surfaces of the synchronizer ring that rub against each other and counterpart retain their structure because of overheating of the contacting surfaces can not occur because of the heat dissipating, interconnecting parts. The uppermost layers of these surfaces can therefore not soften and melt, so that the so-called smoothing is omitted and the coefficient of friction is necessary for synchronization Maintains required height.

Jede der genannten Legierungen sind für den Synchronring und das Gegenstück verwendbar. Der Synchronring und das Gegenstück können aus derselben Legierung bestehen oder auch aus verschiedenen Legierungen.Each of the alloys mentioned are for the synchronizer ring and the counterpart usable. The synchronizer ring and the counterpart can consist of the same alloy or from different alloys.

Preisgünstige Legierungen und ihre besonders geeignete Verwendung sind aus den Unteransprüchen 2 und 3 ersichtlich.Inexpensive alloys and their particularly suitable use are apparent from the subclaims 2 and 3.
