Abstract

The draw key (diving-key) transmission for engines or drive units, with gearwheels in permanent mesh, belongs to the category of mechanical transmissions with synchronisation. Conventional transmissions used in motor vehicles employ a fork shift. Here, the process of gear selection involves a change in direction of motion. By virtue of the fact that this draw key transmission involves a simple backward and forward motion of the gear lever, gear changing is considerably simpler and the draw key transmission is suitable for automation. At the same time, the advantages of mechanical transmissions are retained. This draw key transmission operates with the hollow main shaft (1) and selector rod (2), which can be displaced in the hollow main shaft, and individual gears are selected by means of its small keys (4). Power transmission takes place via these small keys and a flange (3) on the hollow main shaft. Synchroniser rings (8), both with the ability to move freely on the hollow main shaft, are arranged between gearwheels (7). Balls or detent pins in small keys actuate the synchroniser rings and lock the gearwheels once a gear has been selected. Intermediate rings (6) determine the path of the gearwheels or can be integrated into the gearwheels. Axial springs (9) between the gearwheels and the synchroniser rings determine the path of the synchroniser rings and allow synchronisation during selection. <IMAGE>

Description

Es sind Ziehkeilgetriebe z. B. aus der DE-32 11 108 A1 bekannt, bei denen axial in Nuten der Schaltwelle geführte Keile bewegt werden, die in eine Innenverzahnung der zu schaltenden Zahnräder eingreifen. Derartige Ziehkeilgetriebe sind auch mit Kugeln oder Rollen ausgeführt worden. Es ist auch vorgeschlagen worden, Zwischenringe zwischen den Rädern anzuordnen, um ein Synchronisieren des zu schaltenden Rades zu erzielen.There are pull wedge gears z. B. from DE-32 11 108 A1 known, in which axially in grooves the shift shaft guided wedges are moved into a Engage the internal teeth of the gears to be switched. Such pull wedge gears are also with balls or rollers been carried out. It has also been suggested to use intermediate rings to be placed between the wheels in order to synchronize to achieve the wheel to be switched.

Leider durch anstoßmäßige, wechselhafte und dynamische Kraftbelastung eine Getriebes sind diese Ziehkeilgetriebe wegen ihrer Kraftübertragungsweise nicht genug zuverlässig.Unfortunately through offensive, changeable and dynamic load these pull wedge gears are a transmission their way of power transmission is not reliable enough.

Die Erfindung bezieht sich auf derartige Getriebe und hat sich zur Aufgabe gesetzt die Zuverlässigkeit und Drehmomentübertragung durch feste und besser ausgedehnte Kraftübertragung wesentlich zu erhöhen.The invention relates to such transmissions and has the task is reliability and torque transmission through fixed and better extended power transmission to increase significantly.

Die Lösung der Aufgabe besteht darin, daß gemäß Kennzeichen des Patentanspruch 1 die Übertragungskräfte nicht nur durch die Hohlhauptwelle (1), sondern auch durch die Schaltstange (2) übertragen werden.The solution to the problem is that according to the characterizing part of claim 1, the transmission forces are transmitted not only by the hollow main shaft ( 1 ) but also by the shift rod ( 2 ).

Das Ziehkeilgetriebe, wie es in der Figur gezeigt ist, weist auf dauernd kämmende Zahnräder (7), Synchronringe (8) zwischen den Zahnrädern (7), eine Hohlhauptwelle (1), die längliche Ausschnitte aufweist, eine schiebbar in der Hohlhauptwelle (1) angeordnete Schaltstange (2) und kleine, auf der Schaltstange (2) angeordnete Keile (4), die entlang der Ausschnitte der Hohlhauptwelle (1) gleiten, hierbei die Zahnräder (7) arretieren und dadurch die Gänge wechseln. Kugeln oder Mitnehmerstifte in kleinen Keilen (4) sind vorgesehen zum Betätigen der Synchronringe (8) und zum Arretieren der Schaltstange (2). The pull wedge gear, as shown in the figure, has permanently intermeshing gears ( 7 ), synchronizer rings ( 8 ) between the gears ( 7 ), a hollow main shaft ( 1 ), which has elongated cutouts, which can be pushed in the hollow main shaft ( 1 ) arranged shift rod ( 2 ) and small wedges ( 4 ) arranged on the shift rod ( 2 ) that slide along the cutouts of the hollow main shaft ( 1 ), locking the gears ( 7 ) and changing gears. Balls or driving pins in small wedges ( 4 ) are provided for actuating the synchronizer rings ( 8 ) and for locking the shift rod ( 2 ).

Zwischen den Zahnrädern (7) und den Synchronringen (8) sind die Synchronisation zulassende Axialfedern (9) vorgesehen. Ein fest mit der Hohlhauptwelle (1) verbundener Flansch (3), der in Längsnuten der Schaltstange (2) eingreift, überträgt das Drehmoment sowohl durch die Hohlhauptwelle (1), als auch durch die Schaltstange (2).Between the gears (7) and the synchronizer rings (8) permitting the synchronization of axial springs (9) are provided. A flange ( 3 ) which is firmly connected to the hollow main shaft ( 1 ) and which engages in the longitudinal grooves of the shift rod ( 2 ) transmits the torque both through the hollow main shaft ( 1 ) and through the shift rod ( 2 ).

Dieses Ziehkeilgetriebe kann betrachtet werden als eine neue Bereicherung einer Reihe von Getrieben im KFZ- und Maschinenbau.This pull wedge gear can be considered a new one Enrichment of a number of gearboxes in automotive and mechanical engineering.
