Die Erfindung betrifft eine Schaltvorrichtung für Zahnräderwechselgetriebe von Kraftfahrzeugen mit einer zum Gangschalten längsverschiebbaren und zur Gangvorwahl drehbaren Schaltwelle, mehreren Schaltgabeln, einem mit der Schaltwelle fest verbundenen Schaltfinger, der wahlweise mit einer der Schaltgabeln in Eingriff gebracht werden kann, und einem die' jeweils außer Eingriff befindlichen · Schaltgabeln blockierenden, auf der Schaltwelle gelagerten Sperrglied, welches in Richtung des Vor- ip wählens mit dem Schaltfinger gekoppelt und gegen Bewegung in Richtung des Schaltens gesichert ist. ■The invention relates to a switching device for gear change transmissions of motor vehicles with a shift shaft that is longitudinally displaceable for gear shifting and rotatable for gear preselection, several Shift forks, a shift finger firmly connected to the shift shaft, which can optionally be connected to one of the Shift forks can be brought into engagement, and one of the 'respectively disengaged Shifter forks blocking, on the selector shaft mounted locking member, which in the direction of the fore ip dialing is coupled to the shift finger and secured against movement in the direction of shifting. ■
Eine aus der österreichischen Patentschrift 193 255 bekannte Schaltvorrichtung der beschriebenen Art besitzt eine mittels einer Bohrung auf der Schaltwelle drehbar gelagerte Sperrplatte, die durch einen zur Schaltwelle konzentrischen Schlitz und einen den Schlitz durchsetzenden, am Getriebegehäuse festen Bolzen gegen Verschieben in Schaltrichtung und gegen Verkanten gesichert ist.A switching device of the type described known from Austrian patent specification 193 255 has a locking plate rotatably mounted by means of a hole on the shift shaft, which is supported by a for Shift shaft concentric slot and a slot that penetrates the slot and is fixed to the transmission housing The bolt is secured against shifting in the switching direction and against tilting.
Als Aufgabe ist bei der Erfindung gestellt, eine einfachere Ausbildung zu erreichen durch ein Sperrglied, das ohne zusätzliche konstruktive Mittel gegen Verschieben in Schaltrichtung und gegen Verkanten gesichert ist und welches sich in einfacher Weise aus einem Blech herstellen läßt.The object of the invention is to achieve a simpler design by means of a locking member, this without additional constructive means against shifting in the switching direction and against tilting is secured and which can be produced in a simple manner from sheet metal.
Die Erfindung besteht darin, daß das Sperrglied aus einer rechteckigen, mit einem vom Schaltfinger durchsetzten, in Richtung der Schaltbewegung verlaufenden Schlitz versehenen Grundplatte. — wie an sich bekannt — besteht, die, wie ebenfalls für sich bekannt, zwei parallele, von ihr abgebogene und von der Schaltwelle durchdrungene Lagerschenkel sowie zwei ebenfalls von ihr abgebogene Sperrfinger aufweist, und daß das Sperrglied durch Anliegen der Lagerschenkel an zwei Lageraugen des Getriebegehäuses für die Schaltwelle gegen Verschieben gesichert ist.The invention consists in that the locking member consists of a rectangular, with one of the shift finger interspersed base plate provided with a slot running in the direction of the switching movement. - like on known - consists of, as is also known, two parallel, bent from it and Bearing legs penetrated by the selector shaft and two locking fingers also bent by it has, and that the locking member by abutment of the bearing legs on two bearing eyes of the gear housing for the selector shaft is secured against shifting.
Ein weiteres Merkmal der Erfindung besteht darin, daß das Sperrglied in seiner Abwicklung aus einem Blech mit rechteckiger Grundform und vier an die Rechteckseiten anschließenden Lappen besteht, welche paarweise nach entgegengesetzten Seiten der Rechteckebene umgebogen sind und die beiden Lagerschenkel sowie die beiden Sperrfinger bilden.Another feature of the invention is that the locking member in its development from a Consists of sheet metal with a rectangular basic shape and four tabs attached to the sides of the rectangle, which are bent in pairs to opposite sides of the plane of the rectangle and the two Form bearing legs and the two locking fingers.
Aus der deutschen Patentschrift 548 565 ist eine Vorrichtung zum Verriegeln der Schaltgabeln von
Zahnräderwechselgetrieben bekannt, die ein Sperrglied mit einem als ebenes Blech ausgebildeten Grundkörper
aufweist. Es sind besondere Teile zur Lagerung des Sperrgliedes an dem Getriebegehäuse erforderlich,
welche zusätzlich eine vom Erfindungs-Schaltvorrichtung für Zahnräderwechselgetriebe
von KraftfahrzeugenFrom the German patent specification 548 565 a device for locking the shift forks of gear change transmissions is known, which has a locking member with a base body designed as a flat sheet metal. There are special parts required for mounting the locking member on the gearbox housing, which also have a switching device from the invention for gear change transmissions

The shift finger penetrating the locking plate forms the gear-side End of a conventional gear stick supported by a ball.
Eine aus der deutschen Auslegeschrift 1116 544 bekannte Schalt- und Sperrvorrichtung für Geschwindigkeitswechselgetriebe enthält eine Sperrplatte mit zwei parallelen, seitlich abgebogenen und von einer Schaltachse durchdrungenen Lagerschenkeln. Die bekannte Sperrplatte ist zusammen mit dem Schaltglied zum Vorwählen der Gänge seitlich verschiebbar auf der Schaltachse gelagert. Eine am Getriebegehäuse befestigte Führungsplatte ist dazu vorgesehen, die Sperrplatte gegen Drehen zu sichern. Die bekannte Sperrplatte wirkt anders als das Sperrglied nach der Erfindung und ist dementsprechend unterschiedlich ausgebildet.A switching and locking device for speed change transmissions known from German Auslegeschrift 1116 544 contains a locking plate with two parallel, laterally bent and one by one Switching axis penetrated bearing legs. The known locking plate is together with the switching element for preselecting the gears, mounted on the shift axis so that it can be moved laterally. One on the gearbox attached guide plate is provided to secure the locking plate against rotation. The well-known Locking plate acts differently than the locking member according to the invention and is accordingly different educated.
