Abstract
Description
Die Erfindung geht aus von einer Betätigungseinrichtung für ein Schaltgetriebe gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention is based on an actuating device for a Manual transmission according to the features of the preamble of claim 1.
Zur
Verbesserung der Schaltqualität
eines Getriebes ist beispielsweise aus der
Aufgabe der Erfindung ist es, eine Betätigungseinrichtung eines Schaltgetriebes mit einem Schalthebel zu entwickeln, die in der Lage ist, die Weiterleitung hochfrequenter Schalt- bzw. Synchronstörungen auch beim Aufbringen unterschiedlich hoher Schaltkräfte durch den Fahrer zu vermeiden.task The invention is an actuator to develop a gearbox with a shift lever that in is capable of forwarding high-frequency switching or synchronous interference, too to avoid when applying different high switching forces by the driver.
Die Aufgabe wird durch die im Anspruch 1 angegeben Merkmale gelöst.The The object is achieved by the features specified in claim 1.
Durch die erfindungsgemäße Betätigungseinrichtung kann auch beim Aufbringen unterschiedlich hoher Schaltkräfte die Weiterleitung hochfrequenter Schaltstörungen, die sich in Form von Schwingungen, Vibrationen oder Kratzen beim Schalten bemerkbar machen, wirksam unterbunden werden. Je größer die Betätigungskraft ist, die über den Getriebe- Handschalthebel auf die Betätigungseinrichtung aufgebracht wird, desto größer ist die Auslenkung des keilförmigen Schaltzapfens innerhalb der Schalthülse. Durch die Auslenkung des Schaltzapfens vergrößert sich die Anlagefläche des Schaltzapfens gegenüber der elastischen Anschlagfläche, so dass damit auf gewünschte Art und Weise eine stark progressiv verlaufende Federkennlinie umsetzbar ist, die – wie Untersuchungen gezeigt haben- beim Aufbringen unterschiedlich hoher Schaltkräfte sich besonders positiv auf die gewünschte Dämpfung auswirkt.By the actuating device according to the invention can also when applying different high switching forces the Forwarding of high-frequency switching noise, which takes the form of vibrations, Vibration or scratching when switching noticeable, effective be prevented. The bigger the operating force is that over the Gear shift lever applied to the actuator the bigger it gets the deflection of the wedge-shaped Shifter within the shift sleeve. By the deflection of the switching pin increases the contact surface of the switching pin opposite the elastic stop surface, so that with it on desired Way a highly progressive spring characteristic feasible is that - how Investigations have shown- when applying different levels Shifting forces themselves especially positive for the desired Damping effect.
Durch die in den Unteransprüchen angegebenen Merkmale sind weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Betätigungseinrichtung möglich.By in the subclaims specified features are further advantageous embodiments and Further developments of the actuator possible.
Zur Umsetzung einer leicht montierbaren Betätigungseinrichtung wird als elastische Anschlagfläche ein Rundkörper vorgeschlagen, der in der Schalthülse eingesetzt ist.to Implementation of an easily assembled actuator is called elastic stop surface a round body proposed, which is inserted in the shift sleeve.
In Weiterbildung des elastischen Rundkörpers wird vorgeschlagen, dass dieser Teil eines Formstückes aus thermoplastischem Elastomer ist.In Further development of the elastic round body is suggested that this part of a fitting made of thermoplastic elastomer.
Um Überlastungen bzw. einen vorzeitigen Verschleiß der elastischen Anschlagfläche zu vermeiden, sind in der Schalthülse zwei seitliche Anschläge vorgesehen, an die – nachdem aufgrund der Schaltkräfte die elastische Anschlagfläche entsprechend verformt worden ist – die Kraft bzw. das Schaltmoment direkt vom Schaltzapfen über die Schalthülse auf die Schaltwelle übertragen wird. Zusätzlich kann damit auch die durch die elastische Anschlagfläche erreichte Filterfunktion bei harten und schnellen Schaltvorgängen außer Kraft gesetzt werden. Dies hat keine spürbaren Nachteile für den Schaltkomfort, da die Schaltstörungen nur bei normalen und langsamen Schaltvorgängen störend in Erscheinung treten.To overloads or to prevent premature wear of the elastic stop surface, are in the shift sleeve two lateral stops provided to the - after due to the switching forces the elastic stop surface has been deformed accordingly - the force or the switching torque directly from the switching pin over the shift sleeve transferred to the shift shaft becomes. In addition, can so that the filter function achieved by the elastic stop surface be overridden during hard and fast shifts. This has no noticeable Disadvantages for the shifting comfort, since the switching disturbances only with normal and slow switching operations disturbing appear.
