Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein wirtschaftlich herstellbares und handliches Mehrgang-Getriebe zu schaffen.The present invention has for its object to provide an economically producible and handy multi-speed transmission.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass das Getriebe mehrere axial verschiebbare Schalträder aufweist, wobei jedes Schaltrad jeweils mit einem Schaltbügel zusammenwirkt und die Schaltbügel mittels dem Schaltschieber betätigbar sind. Dabei weisen die Schaltbügel jeweils eine, fest am Getriebegehäuse angeordnete, Schwenkachse auf, um eine definiert Schalt-Stellung der Schalträder und damit ein zuverlässiges Umschalten zu gewährteisten.According to the invention the object is achieved in that the transmission has a plurality of axially displaceable switching wheels, wherein each ratchet cooperates with a respective shift bracket and the shift bracket by means of the slide switch can be actuated. In this case, the switching bracket each have a fixedly arranged on the transmission housing, pivot axis to a defined switching position of the switching wheels and thus granted a reliable switching.

Dadurch, dass mehrere Schalträder zur Anwendung gelangen, weist das Getriebe mehr als zwei Gänge auf. Ferner sind durch die Betätigung des Schaltschiebers alle Schaltbügel betätigbar und dadurch eine hohe Handlichkeit sichergestellt. Durch ein axiales Verschieben des Schaltschiebers ist ein Umschalten des Getriebes von einer Getriebestufe in eine andere Getriebestufe sicher gewährleistet. Die federnd ausgebildeten Schaltbügel gewährleisten ein sicheres Umschalten, insbesondere beim Umschalten des Getriebes im Stillstand, da die Schaltbügel die entsprechenden Teile des Getriebes in Eingriff bringen, spätestens bei einem Antrieb des Getriebes.Due to the fact that several switching wheels are used, the transmission has more than two gears. Furthermore, all switching elements are actuated by the operation of the slide switch, thereby ensuring a high degree of maneuverability. By an axial displacement of the slide switch a switching of the transmission from one gear stage to another gear stage is assured. The spring-trained switching bracket ensure a safe switching, especially when switching the gearbox at a standstill, since the switch bracket bring the corresponding parts of the transmission into engagement, at the latest in a drive of the transmission.

Vorteilhafterweise sind am Getriebegehäuse zur Führung der Schaltbügel Lagerteile angeordnet, insbesondere Durchgangsbohrungen, zur bereichsweisen Aufnahme der Schaltbügel. Ferner ist durch die verschwenkbare Lagerung der Schaltbügel am Getriebegehäuse durch die Hebelwirkung eine Kraftumsetzung zwischen der auf den Schaltschieber wirkenden Betätigungskraft und der auf das jeweilige Schaltrad wirkenden Stellkraft möglich, je nach Positionierung der Schwenkachse am Getriebegehäuse.Advantageously, bearing parts are arranged on the gear housing for guiding the switch bracket, in particular through holes, for receiving the switch bracket in regions. Further, by the pivotal mounting of the switch bracket on the transmission housing by the leverage a force conversion between the force acting on the slide actuator and the force acting on the respective ratchet force is possible, depending on the positioning of the pivot axis on the transmission housing.

Vorteilhafterweise weist jeder Schaltbügel jeweils wenigstens ein Eingriffteil und wenigstens ein Schaltteil zum Schalten des korrespondierenden Schaltrades auf, wobei das Eingriffteil mit dem korrespondierenden Schaltrad zusammenwirkt und das Schaltteil als Übertragungsmittel der Betätigungskraft vom Schaltschieber zum Eingriffteil dient.Advantageously, each switching bracket each has at least one engaging part and at least one switching part for switching the corresponding switching wheel, wherein the engaging part cooperates with the corresponding ratchet and the switching member serves as a transmission means of the actuating force from the slide switch to the engaging part.

Der Schaltschieber weist vorzugsweise zur Lagerung des Schaltteils zumindest eine Ausnehmung auf, und stellt dadurch eine kompakte Bauweise des Getriebes sicher. Ausserdem ist eine Ausnehmung wirtschaftlich herstellbar und erleichtert die Endmontage des Getriebes.The slide switch preferably has at least one recess for supporting the switching part, thereby ensuring a compact design of the transmission. In addition, a recess is economical to produce and facilitates the final assembly of the transmission.

Die Ausnehmung ist vorzugsweise quer zur Längsachse des Getriebes und im Wesentlichen tangential zu den Schalträdern durchgehend ausgebildet, um eine einfache Endmontage und eine sichere Führung des Schaltteils im Schaltschieber sicherzustellen.The recess is preferably formed transversely to the longitudinal axis of the transmission and substantially tangentially to the switching wheels, to ensure a simple final assembly and secure guidance of the switching part in the slide switch.

Die Ausnehmung weist vorteilhafterweise in Längsrichtung eine Steuerkulisse zum Verschwenken der Schaltbügel um die Schwenkasche auf, um eine konstruktiv einfache und wirtschaftliche Ansteuerung der Schaltbügel durch den Schaltschieber sicherzustellen. Die Steuerkulisse verschwenkt je nach Position des Schaltschiebers einzelne Schaltbügel und verschiebt dadurch das zum jeweiligen Schaltbügel korrespondierende Schaltrad.The recess has advantageously in the longitudinal direction of a control link for pivoting the switch bracket to the swivel ash to ensure a structurally simple and economical control of the switch bracket by the slide switch. The control link pivots depending on the position of the slide switch individual switching bracket and thereby shifts the corresponding switching bracket corresponding ratchet.

Die Schaltbügel durchgreifen die Ausnehmung vorteilhafterweise mit ihrem jeweiligen Schaltteil, das als Verbindungsteil fungiert.The switch bracket pass through the recess advantageously with their respective switching part, which acts as a connecting part.

Die Ausnehmung quer zur Längsachse des Getriebes weist vorzugsweise eine Höhe auf, die im Wesentlichen dem Durchmesser des Schaltteils mit einem Spiel entspricht, um ein optimales Umschalten zu gewährleisten. Das Spiel ermöglicht bei der Herstellung des Getriebes eine höhere Toleranz und wirkt sich dadurch wirtschaftlich positiv auf die Herstellungskosten aus.The recess transversely to the longitudinal axis of the transmission preferably has a height which substantially corresponds to the diameter of the switching part with a game in order to ensure optimum switching. The game allows in the manufacture of the transmission a higher tolerance and thereby has a positive economic effect on the manufacturing cost.

Die Steuerkulisse weist vorteilhafterweise zwei Schaltstufen auf, wobei unterschiedliche und miteinander korrespondierende Schaltstufen durch eine Rampe miteinander verbunden sind.The control link advantageously has two switching stages, wherein different and mutually corresponding switching stages are connected to each other by a ramp.

In addition, the slide switch 3 on the side facing away from the gear housing 6 side surface on an actuating element 25 for setting the slide switch 3.

Durch den Schaltschieber 3 ist das Getriebe 1 zwischen drei unterschiedlichen Gängen schaltbar. In den Fig. 1b bis 3b ist der Schaltschieber 3 mit der Steuerkulisse 20 dargestellt, wobei die Schaltteile 15 im Querschnitt dargestellt sind, um deren Positionen in der Steuerkulisse 20 in den drei verschiedenen Gängen klar darzustellen. In der Fig. 1a ist das Getriebe 1 im ersten Gang und die beiden Schaltbügel 5a, 5b stehen senkrecht zur Längsachse L des Getriebes 1, wie dies insbesondere aus Fig. 1b ersichtlich ist. In der Fig. 2b ist der Schaltschieber 3 im Gegensatz zu den in Fig. 1a und 1b in Arbeitsrichtung A verschoben dargestellt und das Getriebe 1 im zweiten Gang. Der den Schaltschieber 3 durchgreifende Bereich des Schaltteils 15 des zweiten Schaltbügels 5b wurde in die zweite Schaltstufe 23 der Steuerkulisse 20 bewegt und der zweite Schaltbügel 5b dadurch um seine Schwenkachse S um einen Winkel α verschwenkt. Das Verschwenken des Schaltbügels 5b, insbesondere des Eingriffteils 14 führt zu einer axialen Bewegung des zweiten Schaltrads 4b.By the slide switch 3, the transmission 1 is switchable between three different gears. In the Fig. 1b to 3b the slide switch 3 is shown with the control link 20, wherein the switching parts 15 are shown in cross section to clearly represent their positions in the control link 20 in the three different gears. In the Fig. 1a is the transmission 1 in the first gear and the two shift yokes 5a, 5b are perpendicular to the longitudinal axis L of the transmission 1, as this particular Fig. 1b is apparent. In the Fig. 2b is the slide switch 3 in contrast to the in Fig. 1a and 1b shown displaced in the direction A and the transmission 1 in second gear. The switching slide 3 by cross-section of the switching part 15 of the second switching bracket 5b was moved to the second switching stage 23 of the control link 20 and the second switching bracket 5b thereby pivoted about its pivot axis S by an angle α. The pivoting of the switching bracket 5b, in particular of the engaging part 14 leads to an axial movement of the second switching wheel 4b.

Bei einer weiteren Bewegung des Schaltschiebers 3 in Arbeitsrichtung A des in Fig. 3a und 3b dargestellten Schaltschiebers 3, wird das Getriebe 1 in den dritten Gang geschaltet. Das Schaltteil 15 des ersten Schaltbügels 5a wird durch die Bewegung mittels der Rampe 24a auf die zweite Schaltstufe 23a der Steuerkulisse 20 bewegt, was zu einem Verschwenken (Winkel β) des ersten Schaltbügels 5a um seine Schwenkachse S führt.In a further movement of the slide switch 3 in the working direction A of in Fig. 3a and 3b shown switching slide 3, the transmission 1 is switched to the third gear. The Switching part 15 of the first switching bracket 5a is moved by the movement by means of the ramp 24a to the second switching stage 23a of the control link 20, which leads to a pivoting (angle β) of the first switching bracket 5a about its pivot axis S.

Das, insbesondere in Fig. 4 dargestellte, Getriebe 1 weist zwei, in Längsrichtung L des Getriebes 1, nacheinander angeordnete Planetengetriebe auf, wie sie aus dem Stand der Technik allgemein bekannt sind.That, especially in Fig. 4 illustrated, transmission 1 has two, in the longitudinal direction L of the transmission 1, successively arranged planetary gear, as are well known in the prior art.

In einem weiteren, in Fig. 7 dargestellten, Ausführungsbeispiel weist das Getriebe 1 anstelle zweier nacheinander geschalteten Planetengetriebe ein Planetengetriebe 31 und ein Stirnradgetriebe 32 auf.In another, in Fig. 7 illustrated embodiment, the transmission 1 instead of two successively connected planetary gear planetary gear 31 and a spur gear 32 on.
