Abstract
Bei einem Getriebe mit zumindest einer Schaltschiene (1), an der zumindest eine Schaltgabel (6) angeordnet ist, soll die Schaltschiene (1) im Querschnitt rund ausgebildet sein.In a transmission with at least one shift rail (1), on which at least one shift fork (6) is arranged, the shift rail (1) should have a round cross-section.
Description
Die Erfindung betrifft ein Getriebe nach dem Oberbegriff des Anspruchs 1.The invention relates to a transmission according to the preamble of claim 1.
Aus dem Stand der Technik wird zunächst auf die
Derartige Schaltschienen mit Schaltgabeln dienen in Fahrzeuggetrieben zum Schalten in die einzelnen Gänge. Hierzu werden Schaltmuffen durch ein Verschieben der Schaltschiene und Schaltgabel bewegt, wobei dieses Schieben durch einen Schaltfinger erfolgt, der wiederum, beispielsweise mit dem Ganghebel, verbunden ist.Such shift rails with shift forks are used in vehicle transmissions for switching in the individual gears. For this purpose, shift sleeves are moved by moving the shift rail and shift fork, this pushing is done by a shift finger, which in turn, for example, with the gear lever, is connected.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Getriebe der o. g. Art zu schaffen, bei dem das Getriebeelement aus Schaltschiene und Schaltgabel wesentlich verbessert ist. Die Steifigkeit soll erhöht, die Herstellung verbilligt und das Getriebeelement insgesamt leichter werden.The present invention is based on the object, a transmission of o. G. To create type in which the transmission element of shift rail and shift fork is significantly improved. The stiffness should be increased, the production cheaper and the transmission element as a whole easier.
Zur Lösung der Aufgabe führen die Merkmale nach den Ansprüchen 1 und 2. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.To achieve the object, the features according to
Eine runde Schaltschiene besitzt ein Optimum an Formsteifigkeit und ein Optimum an Widerstandsmoment. Aus diesem Grunde bietet sich die erfindungsgemässe Schaltschiene vor allem auch für automatisierte Getriebe an.A round shift rail has an optimum of stiffness and an optimum resistance moment. For this reason, the inventive shift rail offers above all for automated transmissions.
Bevorzugt weist die Schaltschiene einen Rohrabschnitt auf, auf den zumindest einseitig, bevorzugt beidseitig, eine Hülse als Lager aufgesetzt ist. Erfindungsgemäss soll diese Hülse aus Kunststoff bestehen, d. h., die Hülse kann auf das bzw. die Enden des Rohrabschnittes aufgespritzt werden. Dabei ist es beim Aufspritzen auch gleich möglich, der Hülse Ausnehmungen einzuformen, die dem Eingriff von Rastierungselementen dienen können.Preferably, the shift rail on a pipe section on which at least one side, preferably on both sides, a sleeve is placed as a bearing. According to the invention, this sleeve is made of plastic, d. h., The sleeve can be sprayed onto the or the ends of the pipe section. It is also possible during spraying, einzuformen the sleeve recesses that can serve the engagement of Rastierungselementen.
Ein weiterer Erfindungsgedanke der vorliegenden Erfindung, der insbesondere sehr gut mit einer rohrförmigen Schaltschiene verwirklicht werden kann, bezieht sich auf die Verbindung zwischen Schaltgabel und Schaltschiene. Erfindungsgemäss erfolgt die Verbindung durch eine Abdeckung, welche die Schaltschiene übergreift. Dabei soll die Abdeckung der Schaltschiene flächig anliegen, d. h., die Abdeckung umgreift bogenförmig die rohrförmige Schaltschiene in einem relativ grossen Teilbereich, so dass es sich anbietet, die Abdeckung mit der rohrförmigen Schaltschiene zu verkleben. Die heute bekannten Klebstoffe können aufgrund der flächigen Anlage von Abdeckung an Schaltschiene eine hervorragende Verbindung bewirken.Another inventive concept of the present invention, which can be realized particularly well with a tubular shift rail, refers to the connection between the shift fork and shift rail. According to the invention, the connection is made by a cover which engages over the shift rail. The cover of the shift rail should lie flat, d. h., The cover engages arcuately the tubular shift rail in a relatively large portion, so it is convenient to glue the cover with the tubular shift rail. The adhesives known today can cause an excellent connection due to the flat contact of cover to shift rail.
Ferner liegt die Abdeckung mit entsprechenden Schenkelstreifen flächig den Schenkeln der Schaltgabel von aussen her an. Dementsprechend ist die Kontur der Abdeckung in diesen Bereichen auch der Aussenkontur der Schenkel der Schaltgabel angepasst. Die Aussenfläche der Schenkel der Schaltgabel ist ebenfalls flächig ausgestaltet. Auch hier kann somit eine Verbindung durch Verkleben erfolgen.Furthermore, the cover with corresponding leg strip is flat against the legs of the shift fork from the outside. Accordingly, the contour of the cover in these areas is also adapted to the outer contour of the legs of the shift fork. The outer surface of the legs of the shift fork is also configured flat. Again, therefore, a connection can be made by gluing.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung; diese zeigt in ihrer einzigen Figur eine perspektivische Ansicht einer Schaltschiene mit weiteren angeformten Funktionselementen.Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing; this shows in its single figure, a perspective view of a shift rail with other molded functional elements.
