Description
Die Erfindung betrifft eine Schalteinheit, z.B. einen Schaltdom für ein mehrstufiges Schaltgetriebe, insbesondere für ein Kraftfahrzeug, mit einer Schaltwelle zum Schalten von Gangstufen.The invention relates to a switching unit, e.g. a shift dome for a multi-stage manual transmission, in particular for a motor vehicle, with a shift shaft for switching gear stages.
Bekannterweise ist zum Wählen und Schalten eines Gangs eine einzige axial verschiebbar und schwenkbar angeordnete Schaltwelle vorgesehen, an welcher ein Schaltfinger fest angeordnet ist, der in eine Schaltkulisse eingreift. Zur Anbindung der Schaltwelle an einen manuellen Schalthebel oder einen Aktuator ist in der Regel am Ende der Schaltwelle ein Schalthebel fest angeordnet sowie eine Eingriffsmöglichkeit für einen Wählhebel vorgesehen.As is known, a single axially displaceable and pivotable shift shaft is provided for selecting and shifting a gear, on which a shift finger is fixedly arranged, which engages in a shifting gate. To connect the gearshift shaft to a manual gearshift lever or an actuator, a gearshift lever is generally fixed at the end of the gearshift shaft and an engagement option for a gearshift lever is provided.
Eine derartige Anbindung ist beispielsweise durch die
Bei Schaltwellen, die eine kombinierte Funktion aufweisen, nämlich Wählen und Schalten einer Gangstufe, besteht das Problem, dass der Schalthebel beim Wählen der Schaltgasse durch eine axiale Bewegung immer mitbewegt wird.With shift shafts that have a combined function, namely the selection and shifting of a gear stage, there is the problem that the shift lever is always moved by an axial movement when the shift gate is selected.
Gattungsgemäße Schalteinheiten gehen aus
Der Erfindung liegt daher die Aufgabe zugrunde, eine Schalteinheit für ein mehrstufiges Schaltgetriebe zu schaffen, bei welcher die Funktionen „Schalten“ und „Wählen“ entkoppelt sind.The invention is therefore based on the object of providing a switching unit for a multi-stage manual transmission in which the “switching” and “selecting” functions are decoupled.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.
Es ist ein besonderer Vorteil der Erfindung, dass die Funktionen zum Wählen und Schalten von Gangstufen voneinander entkoppelt durchführbar sind. Durch diese Maßnahme müssen z.B. beim Wählen einer Schaltgasse die Massen der Schaltmittel, d. h. Schaltwelle, Schalthebel und Zusatzmasse, nicht mitbewegt werden, wodurch der Schaltkomfort erhöht wird.It is a particular advantage of the invention that the functions for selecting and shifting gear stages can be carried out in a manner that is decoupled from one another. With this measure, e.g. when choosing a shift gate, the masses of the switching means, d. H. Shift shaft, shift lever and additional mass, are not moved, which increases the shift comfort.
In vorteilhafter Weise ist die Schaltwelle schwenkbar, jedoch axial unverschiebbar in einem Schaltdomgehäuse der Schalteinheit gelagert. Ein in eine Schaltkulisse eingreifender Schaltfinger ist mittels einer Halterung drehfest mit der Schaltwelle verbunden und gegenüber der Schaltwelle axial verschiebbar auf der Schaltwelle angeordnet.In an advantageous manner, the selector shaft is pivotable, but axially immovable, in a shift dome housing of the shift unit. A shift finger engaging in a shift link is connected to the shift shaft in a rotationally fixed manner by means of a holder and is arranged on the shift shaft so as to be axially displaceable relative to the shift shaft.
Die Halterung ist vorzugsweise zylinderförmig ausgebildet und umfasst die Schaltwelle koaxial. Die Halterung weist eine Innenverzahnung auf, die in eine Außenverzahnung der Schaltwelle eingreift, wobei die Verzahnungen als Keilverzahnungen ausgebildet sind.The holder is preferably cylindrical and comprises the shift shaft coaxially. The holder has an internal toothing which engages in an external toothing of the selector shaft, the toothings being designed as splines.
Eine Axialbewegung des Schaltfingers entlang einer Drehachse der Schaltwelle wird durch eine parallel zur Schaltwelle angeordnete Schaltstange, z. B. eine zweite Schaltwelle erzeugt.An axial movement of the shift finger along an axis of rotation of the shift shaft is achieved by a shift rod arranged parallel to the shift shaft, e.g. B. generates a second switching shaft.
Die Schaltstange weist zwei in axialer Richtung voneinander beabstandet angeordnete Anschläge auf, die mit einer Halterung des Schaltfingers in Wirkkontakt stehen.The shift rod has two stops which are spaced apart from one another in the axial direction and are in operative contact with a holder of the shift finger.
