Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Schaltsystem für ein Stufengetriebe gemäß dem Oberbegriff des Patentanspruchs 1. Insbesondere bezieht sich die Erfindung auf ein Schaltsystem für ein Stufengetriebe, bei dem der Antrieb vom Antriebsstrang nicht abgekoppelt werden kann, was beispielsweise in der Regel bei einem Hydrostatgetriebe der Fall ist.The The present invention relates to a switching system for a stepped transmission according to the preamble of the claim 1. In particular, the invention relates to a switching system for a multi-step transmission, where the drive from the drive train can not be decoupled, which, for example, usually at a hydrostatic transmission is the case.
Aus dem Stand der Technik ist bekannt, Fahrantriebe für mobile Arbeitsmaschinen wie z. B. Mähdreschergetriebe als Hydrostatgetriebe auszuführen. Hierbei ist das Getriebe klauengeschaltet ausgeführt. Hierbei entsteht der Nachteil, dass bei maximalem Antriebsmoment die handgeschalteten Getriebegänge nicht mehr über Neutral in einen anderen Gang geschaltet werden können, da die Muffe durch die Hinterstoßung der Klauen verspannt ist.Out the prior art is known drive drives for mobile Working machines such. B. Combine transmission as Hydrostatgetriebe perform. Here, the gear is carried out claw-connected. This creates the disadvantage that at maximum drive torque the manual transmissions no longer over Can be switched to a different gear, because the sleeve is braced by the Hinterstoßung the claws is.

Bei der bekannten Vorrichtung ist der Überlastring auf einer Welle durch Federkraft in Richtung auf die Axialverzahnung drehfest vorgespannt, wobei bei Überschreiten eines vorgegebenen Drehmomentes an der Axialverzahnung und Überschreiten der Federvorspannkraft der Überlastring auf der Welle axial in Richtung einer Kupplungslösung verschiebbar ist. Des Weiteren ist vorgesehen, dass zwischen der Schiebemuffe, dem Überlastring und dem Schaltring kugelförmige Körper angeordnet sind, um die Schiebemuffe von den axialen Kräften der Axialverzahnung freizuhalten.at the known device is the overload ring on a Shaft by spring force in the direction of the axial teeth rotation biased, wherein when exceeding a predetermined Torque at the axial teeth and exceeding the spring biasing force the overload ring on the shaft axially in the direction of a Coupling solution is displaced. Furthermore, it is envisaged that between the sliding sleeve, the overload ring and the Switching ring are arranged spherical body, around the sliding sleeve of the axial forces of the axial toothing kept clear.

Hierbei werden alle oder ein Teil der Nebenaggregate durch ein eine Hydropumpe und einen Hydromotor umfassendes hydraulisches Getriebe angetrieben, wobei das Verteilergetriebe unmittelbar an den Antriebsmotor angeflanscht ist und mit diesem eine kompakte Baueinheit bildet. Das Getriebe umfasst Ausgangswellen zum Antrieb der Nebenantriebe, wobei in den Wellensträngen für die Nebenantriebe lastschaltbare Kupplungen angeordnet sind, so dass unabhängig vom Fahrantrieb die Nebenantriebe unter Last zu- und abschaltbar sind.in this connection All or part of the ancillaries are connected by a hydraulic pump and hydraulic motor comprising a hydraulic motor, wherein the transfer case is flanged directly to the drive motor is and forms a compact unit with this. The gear includes output shafts for driving the auxiliary drives, wherein in the Shaft strands for auxiliary drives power shiftable Clutches are arranged so that regardless of the traction drive the auxiliary drives can be switched on and off under load.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Schaltsystem für ein Stufengetriebe anzugeben, bei dem ein eingelegter Gang und verspanntem Antrieb leicht über die Schiebemuffe des Schaltelementes herausgenommen werden kann.Of the present invention is based on the object, a switching system specify for a multi-step transmission, in which one inserted Gear and tensioned drive slightly over the sliding sleeve of the switching element can be removed.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further embodiments and advantages of the invention are apparent from the dependent claims.
Demnach wird ein Schaltsystem für ein Stufengetriebe vorgeschlagen, welches zumindest ein Schaltelement umfasst, mittels dessen zumindest ein Losrad mit einer Welle drehfest verbunden werden kann, wobei das Schaltelement für jedes Losrad eine axial verschiebliche Stirnklaue umfasst, die mittels einer Schiebemuffe betätigbar ist und über zumindest ein kugelförmiges Element, das über eine Schräge eines axial fest angeordneten und eine Führungsfläche für die Schiebemuffe aufweisenden Rings radial betrachtet nach innen läuft, mit der Schiebemuffe zugehalten wird, so dass die Stirnklaue mit einer Gegenklaue des Losrades in Eingriff kommt.Therefore a switching system for a stepped transmission is proposed, which comprises at least one switching element, by means of which at least a loose wheel can be rotatably connected to a shaft, wherein the switching element for each idler gear an axially displaceable Includes frontal claw, which can be actuated by means of a sliding sleeve is and via at least one spherical element, over a slope of an axially fixed and a guide surface for the sliding sleeve having radially inwardly facing rings, is locked with the sliding sleeve, so that the frontal claw with a counter-claw of the idler gear comes into engagement.
Beim Herausnehmen des Ganges, d. h. beim Betätigen der Schiebemuffe im Öffnungssinne wird das zumindest eine kugelförmige Element von der Schiebemuffe freigegeben, derart, dass die Schiebemuffe wieder in die dem Losrad abgewandte Richtung verschoben wird, wodurch die Stirnklaue aus der Gegenklaue des Losrades herausgenommen wird.At the Removing the aisle, d. H. when operating the sliding sleeve in the opening sense, this will be at least a spherical one Element released by the sliding sleeve, such that the sliding sleeve is again shifted in the direction away from the idler gear, whereby The frontal claw is removed from the counter-claw of the idler gear.
