Description
Die vorliegende Erfindung betrifft eine Schaltkupplung mit Mehrfachsynchronisierung, insbesondere für Schaltgetriebe in Kraftfahrzeugen, gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a clutch with multiple synchronization, in particular for manual transmissions in motor vehicles, according to the preamble of patent claim 1.
Eine Schaltkupplung mit Mehrfachsynchronisierung beschreibt beispielsweise die
Aus der
Die Aufgabe der Erfindung besteht darin, eine Schaltkupplung bereitzustellen, bei der mit fertigungstechnisch einfachen Mitteln ein noch präziserer Synchronisierungsablauf gegeben ist.The object of the invention is to provide a clutch in which an even more precise synchronization sequence is given with manufacturing technology simple means.
Die Aufgabe ist durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The object is solved by the features of patent claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.
Erfindungsgemäß wird vorgeschlagen, dass die Laschen des Zwischenrings in den Ausnehmungen des Gangzahnrads den Zwischenring zentrierend geführt sind. Damit wirkt der Zwischenring nicht nur als Drehmomentübertragungselement, sondern zusätzlich als radiales Führungselement mit definierter Zuordnung der Synchronringe und deren Reibverhalten. Dies vermeidet zum Beispiel zuverlässig Funktionsstörungen, wie ein „Aufschwingen” des Systems oder ein sogenanntes NVH (Noise, Vibration, Harshness), das heißt als Geräusch hörbare oder als Vibration spürbare Schwingungen. Gegebenenfalls ist eine derartige Führung des Zwischenrings auch bei bestehenden Schaltkupplungen problemlos nachrüstbar.According to the invention it is proposed that the tabs of the intermediate ring in the recesses of the gear gear, the intermediate ring are guided centering. Thus, the intermediate ring acts not only as a torque transmitting element, but also as a radial guide element with a defined assignment of the synchronizer rings and their friction behavior. This avoids, for example, reliable malfunctions, such as a "swinging" of the system or a so-called NVH (noise, vibration, harshness), that is, as a sound audible or vibration felt vibrations. Optionally, such a guide of the intermediate ring can be easily retrofitted even with existing clutches.
Erfindungsgemäß sind zur Zentrierung des Zwischenrings die Laschen jeweils mit einem Radialanschlag der korrespondierenden Ausnehmungen in Anlage. Bevorzugt kann der Radialanschlag eine radial innere und/oder äußere Flanke der jeweiligen Ausnehmung sein.According to the invention, the tabs are each in contact with a radial stop of the corresponding recesses for centering the intermediate ring. Preferably, the radial stop may be a radially inner and / or outer edge of the respective recess.
Gegebenenfalls kann dabei der Endbereich der Laschen in einen etwa zylindrischen Abschnitt übergehen, um Radialkräfte bzw. Führungskräfte zuverlässig und weitgehendst verschleißfrei im Gangzahnrad abzustützen.Optionally, the end region of the tabs can pass into an approximately cylindrical section in order to support radial forces or guiding forces reliably and largely wear-free in the gearwheel.
Erfindungsgemäß ist der Zwischenring mit den Laschen im Querschnitt betrachtet abgeknickt ausgebildet, wobei die abgeknickten Führungsabschnitte etwa parallel zu einer korrespondierenden Wand der Ausnehmungen im Gangzahnrad ausgerichtet sind.According to the invention, the intermediate ring with the tabs is formed bent in the cross-section, wherein the bent guide sections are aligned approximately parallel to a corresponding wall of the recesses in the gear wheel.
Schließlich kann in einer bevorzugten Ausgestaltung der Erfindung bzw. besonders kostengünstig und verschleißfest der Zwischenring aus Stahlblech mit im Pressverfahren hergestellten Führungsabschnitten hergestellt sein.Finally, in a preferred embodiment of the invention or particularly inexpensive and wear-resistant, the intermediate ring made of sheet steel can be produced with guide sections produced by the pressing process.
