Erfindungsgemäß gelöst wird die Aufgabe, indem die Rückholmittel zumindest zwei Federelemente aufweisen, welche entgegen einer Auslenkung des Betätigungsorgans aus der Ruhestellung bzw. Nullstellung um die Betätigungsorgan-Schwenkachse wirksam und radial zur Längsachse der Schaltstange einander gegenüberliegend angeordnet sind.According to the invention, the object is achieved in that the return means have at least two spring elements, which are arranged opposite to a deflection of the actuator from the rest position or zero position about the actuator pivot axis and opposite to each other radially to the longitudinal axis of the shift rod.
Aufgrund der symmetrischen Anordnung der Federelemente zur Längsachse der Schaltstange, ergibt sich eine günstige bzw. symmetrische Krafteinleitung in Bezug auf die Längsachse der Schaltstange. Dadurch, dass zwei Federelemente verwendet werden, erübrigt sich ein störungsanfälliger Mechanismus, welche die Erzeugung einer Rückstellkraft bei einer Auslenkung des Betätigungsorgans in beiden Schwenkrichtungen aus der Ruhestellung ermöglicht.Due to the symmetrical arrangement of the spring elements to the longitudinal axis of the shift rod, there is a favorable or symmetrical force introduction with respect to the longitudinal axis of the shift rod.

In this way, simply constructing spring elements can be used, which must be effective only in a direction of loading.
Eine besonders spielfreie Anlage der Federelemente ergibt sich bei einem bevorzugten Ausführungsbeispiel der Erfindung, bei welchem die Federelemente zumindest in der Ruhestellung des Betätigungsorgans eine sich gegenseitig kompensierende Vorspannung aufweisen.A particularly play-free installation of the spring elements results in a preferred embodiment of the invention, in which the spring elements, at least in the rest position of the actuating member have a mutually compensating bias.
Vorzugsweise sind die Rückholmittel derart ausgebildet, dass durch eine Auslenkung des Betätigungsorgans um die Betätigungsorgan-Schwenkachse in einer Schwenkrichtung ein erstes Federelement verformbar ist, wobei das zweite Federelement mittels eines Endanschlags an einer Verformung gehindert ist. Außerdem ist durch eine Auslenkung des Betätigungsorgans um die Betätigungsorgan-Schwenkachse in der entgegengesetzten Schwenkrichtung das zweite Federelement verformbar, wobei das erste Federelement mittels eines Endanschlags an einer Verformung gehindert ist. Dank der bei Verlassen der Ruhestellung wirksamen Endanschläge für die Federelemente kann das Betätigungsorgan in der Ruhestellung mittels der Federelemente spielfrei vorgespannt sein, die Rückstellkräfte aber jeweils durch nur ein Federelement erzeugt werden, ohne dass das andere Federelement eine teilweise kompensierende Federkraft bewirkt. Es ergeben sich Rückholmittel, welche schon bei kleinsten Auslenkungen des Betätigungsorgans hoch wirksam sind.Preferably, the return means are designed such that a first spring element is deformable by a deflection of the actuating member about the actuating member pivot axis in a pivoting direction, wherein the second spring element is prevented by means of an end stop on a deformation. In addition, by a deflection of the actuating member about the actuating member pivot axis in the opposite pivoting direction, the second spring element deformable, wherein the first spring element is prevented by means of an end stop at a deformation. Thanks to the effective when leaving the rest position stops for the spring elements, the actuator can be biased backlash in the rest position by means of the spring elements, but the restoring forces are each generated by only one spring element without the other spring element causes a partially compensating spring force. There are return means, which are highly effective even at the smallest deflections of the actuator.
In der Praxis bewährt hat sich eine Ausbildung der Federelemente als Axialfederelemente, insbesondere als Druck- und/oder als Federelemente. Als besonders einfach und kostengünstig zeichnet sich eine Variante der Erfindung aus, bei welcher die Federelemente als Schraubendruckfedern ausgebildet sind.Has proven useful in practice, a design of the spring elements as Axialfederelemente, in particular as a pressure and / or as spring elements. As particularly simple and inexpensive, a variant of the Invention, in which the spring elements are designed as helical compression springs.
Besonders günstige Verhältnisse ergeben sich, wenn die Spannachsen bzw. Federachsen der Federelemente parallel zur Längsachse der Schaltstange verlaufen und demnach senkrecht zu der ihnen zugeordneten Betätigungsorgan-Schwenkachse. Dabei ist zu berücksichtigen, dass eine Auslenkung des Betätigungsorgans um die Betätigungsorgan-Schwenkachse ausgehend von der Ruhestellung um einen Winkel bis zu 20° zur Ausführung üblicher Steuerungsmaßnahmen ausreichend ist. In diesem Winkelbereich bewirkt eine Auslenkung des Betätigungsorgans um die senkrecht zur Längsachse der Schaltstange verlaufende Betätigungsorgan-Schwenkachse hauptsächlich eine Verlagerung der Anlageflächen für die Federelemente entlang der Längsachse der Schaltstange. Daher ist es besonders vorteilhaft, wenn die Spannachse der Federelemente parallel zur Längsachse der Schaltstange verlaufen und dadurch die Federelemente eine Hauptkomponente der Verlagerung der Anlageflächen für die Federelemente entlang ihrer Spannachsen aufnehmen können.Particularly favorable conditions arise when the clamping axes or spring axes of the spring elements are parallel to the longitudinal axis of the shift rod and therefore perpendicular to their associated actuator pivot axis. It should be noted that a deflection of the actuator to the actuator pivot axis is sufficient starting from the rest position by an angle of up to 20 ° to perform conventional control measures. In this angular range, a deflection of the actuator about the perpendicular to the longitudinal axis of the shift rod extending actuator pivot axis mainly causes a displacement of the contact surfaces for the spring elements along the longitudinal axis of the shift rod. Therefore, it is particularly advantageous if the clamping axis of the spring elements extend parallel to the longitudinal axis of the shift rod and thereby the spring elements can accommodate a major component of the displacement of the contact surfaces for the spring elements along their clamping axes.
Die vorstehend genannten und nachfolgend beschriebenen Vorteile der erfindungsgemäß ausgebildeten Rückholmittel ergeben sich in besonderem Maße, wenn zwei Betätigungsorgan-Schwenkachsen vorgesehen sind und beiden Betätigungsorgan-Schwenkachsen je zwei Federelemente zugeordnet sind, welche jeweils paarweise radial zur Längsachse der Schaltstange einander gegenüberliegend angeordnet sind. Es ergibt sich insgesamt eine symmetrische und robuste Anordnung der Rückholmittel.The above-mentioned and below-described advantages of the present invention formed return means are particularly true when two actuator pivot axes are provided and two actuator pivot axes are each associated with two spring elements, which are each arranged in pairs radially to the longitudinal axis of the shift rod opposite each other. This results in a total symmetrical and robust arrangement of the return means.
Im Falle eines besonders bevorzugten Ausführungsbeispiels der Erfindung sind sämtliche Betätigungsorgan-Bewegungsachsen und Schaltstangen-Bewegungsachsen jeweils mit separaten Rückholmitteln versehen. Die durch die Rückholmittel erzeugbaren Rückstellkräfte sind vorzugsweise derart aufeinander abgestimmt, dass die Gefahr, ungewollt eine Bewegungsachse beim Betätigen einer anderen mit zu betätigen, reduziert wird. Zu diesem Zweck sind die für den Bediener am Betätigungsorgan spürbaren Rückstellkräfte zumindest teilweise unterschiedlich groß, beispielsweise sind die Rückstellkräfte für die Betätigungsorgan-Schwenkachsen spürbar kleiner als diejenigen für Schaltstangen-Schwenkachsen. Insbesondere sind die Rückstellkräfte, welche sich beim Auslenken des Betätigungsorgans um eine Betätigungsorgan-Schwenkachse ergeben, wesentlich kleiner als die Rückstellkräfte, welche sich beim Auslenken des Betätigungsorgans um eine - zumindest in der Ruhestellung des Betätigungsorgans parallele - Schaltstangen-Schwenkachse ergeben.In the case of a particularly preferred embodiment of the invention, all actuator movement axes and shift rod movement axes are each provided with separate return means. The restoring forces that can be generated by the return means are preferably matched to one another in such a way that the risk of unintentionally actuating a movement axis when another is actuated is reduced. For this purpose, the restoring forces felt by the operator on the actuating member are at least partially different in size, for example, the restoring forces for the actuating member pivot axes are noticeably smaller than those for switching rod pivot axes. In particular, the restoring forces, which result in the deflection of the actuator to an actuator pivot axis, much smaller than the restoring forces, which result in the deflection of the actuator to a - at least in the rest position of the actuator parallel - shift rod pivot axis.
Durch eine besonders symmetrische Krafteinleitung, und damit durch eine besonders robuste Bauart zeichnet sich eine Ausführungsart der Erfindung aus, bei welcher die den Betätigungsorgan-Schwenkachsen zugeordneten Federelemente einenends an ein und demselben Bauteil abgestützt sind. In einem besonders bevorzugten Ausführungsbeispiel ist dieses Bauteil von einem Lagerring gebildet, an dessen gegenüberliegenden Stirnseiten jeweils ein Paar der Federelemente anliegt.By a particularly symmetrical introduction of force, and thus by a particularly robust design, an embodiment of the invention is characterized in which the actuator members pivot axes associated spring elements are supported at one end to one and the same component. In a particularly preferred embodiment, this component is formed by a bearing ring, on whose opposite end faces in each case a pair of spring elements abuts.
Vorzugsweise ist die Schaltstange an dem Grundkörper um eine mit der der Längsachse der Schaltstange zusammenfallende Schaltstangen-Drehachse drehbar gelagert. Auch die Schaltstangen-Drehachse ist vorteilhafterweise mit Rückholmitteln versehen, welche entgegen einer Auslenkung um die Schaltstangen-Drehachse aus einer Ruhestellung wirksam sind. Eine besonders kompakte Konstruktion des Handsteuergeräts ergibt sich, indem die Rückholmittel, welche der Drehachse zugeordnet sind, und die Federelemente, welche einer der Betätigungsorgan-Schwenkachsen zugeordnet sind, zumindest teilweise entlang der Längsachse der Schaltstange miteinander überlappen.Preferably, the shift rod is rotatably mounted on the base body about a coincident with the longitudinal axis of the shift rod shift rod rotation axis. Also, the shift rod rotation axis is advantageously provided with return means, which counter to a deflection about the shift rod rotation axis from a rest position are effective. A particularly compact construction of the manual control device results in that the return means, which are associated with the axis of rotation, and the spring elements, which are associated with one of the actuator pivot axes, at least partially overlap each other along the longitudinal axis of the shift rod.

Der Grundkörper 14 ist an seiner Oberseite bzw. an der dem Betätigungsorgan 2 zugewandten Seite mit einem Anbauflansch 16 versehen. Die Schaltstangen-Lagereinrichtung 15 weist einen Schaltstangen-Schwenkbügel 17, ein ringförmiges Schaltstangen-Gelenkstück 18 sowie eine Schaltstangen-Gelenkhülse 19 auf.Furthermore, the

Das über den Befestigungsteller 3 fest mit dem Betätigungsorgan 2 verbundene Betätigungsorgan-Gelenkstück 5, ist mittels zweier Schwenklagerstifte 21, welche einenends in zylindrischen Ausnehmungen 22 an dem Betätigungsorgan-Gelenkstück 5 und anderenends in zylindrischen Ausnehmungen 23 an dem Lagerring 6 angeordnet sind, um eine erste Betätigungsorgan-Schwenkachse 24 schwenkbar gelagert (

Das Betätigungsorgan 2 ist des Weiteren mitsamt der Schaltstange 10 um bzw. entlang vier verschiedenen Schaltstangen-Bewegungsachsen relativ zu dem Grundkörper 14 bewegbar gelagert. So ist die Schaltstange 10 um eine mit der Längsachse 12 der Schaltstange 10 zusammenfallende Schaltstangen-Drehachse 34 an dem Schaltstangen-Gleitstück 13 und an der Schaltstangen-Gelenkhülse 19 drehbar gelagert. Außerdem ist die Schaltstange 10 mitsamt dem Betätigungsorgan 2, welches über die Betätigungsorgan-Aufnahmehülse 7 drehfest und axial unverschieblich mit der Schaltstange 10 verbundenen ist, entlang der Längsachse 12 der Schaltstange 10 an dem Schaltstangen-Gleitstück 13 und an der Schaltstangen-Gelenkhülse 19 verschiebbar geführt (Schaltstangen-Translationsachse 35).The actuating

In der Ruhestellung bzw. Nullstellung des Handsteuergeräts 1 verläuft die erste Schaltstangen-Schwenkachse 36 senkrecht zur Längsachse 12 der Schaltstange 10. In dieser Ruhestellung verläuft sie auch parallel zur ersten Betätigungsorgan-Schwenkachse 24.In the rest position or zero position of the

Insgesamt ist das Betätigungsorgan 2 folglich gegenüber dem Grundkörper 14 um die erste und zweite Betätigungsorgan-Schwenkachse 24, 29, die Schaltstangen-Drehachse 34, die erste und zweite Schaltstangen-Schwenkachse 36, 37 sowie entlang der Schaltstangen-Translationsachse 35 bewegbar. Insgesamt ergibt sich folglich ein 6-Achs-Handsteuergerät.Overall, the
Die Betätigungsorgan-Schwenkachsen 24, 29 und die Schaltstangen-Drehachse 34 schneiden sich in einem mittigen Angriffspunkt 38 des Betätigungsorgans 2. Aus den
Dahingegen schneiden die erste und zweite Schaltstangen-Schwenkachse 36, 37 die Schaltstange 10 in einem deutlich größeren Abstand zum mittigen Angriffspunkt 38 des Betätigungsorgans 2, so dass sich das Betätigungsorgan 2 bei einer Schwenkbewegung um eine der Schaltstangen-Schwenkachsen 36, 37 auf einer Kreisbahn mit einem relativ großen Radius bewegt. Zwar ist der Abstand bzw. Schwenkhebel je nach Lage des Betätigungsorgans 2 entlang der Schaltstangen-Translationsachse 35 verschieden. In allen Stellungen des Betätigungsorgans 2 entlang der Schaltstangen-Translationsachse 35 ist der Abstand bzw. Schwenkhebel aber trotzdem wesentlich größer als derjenige der Betätigungsorgan-Schwenkachsen 24, 29.In contrast, the first and second shift
Dank dieser Maßnahme können die Betätigungsorgan-Schwenkachsen 24, 29 und die Schaltstangen-Schwenkachsen 36, 37 unabhängig voneinander betätigt werden. Außerdem sind die Rückstellkräfte der nachstehend beschriebenen Rückholmittel derart aufeinander abgestimmt, dass eine Betätigung insbesondere der Betätigungsorgan- und der Schaltstangen-Schwenkachsen 24, 29, 36, 37 unabhängig voneinander ohne Schwierigkeiten möglich ist, indem die Rückstellkräfte, welche sich beim Auslenken des Betätigungsorgans 2 um eine der Betätigungsorgan-Schwenkachsen 24, 29 ergeben, für den Bediener spürbar kleiner sind als diejenigen Rückstellkräfte, welche sich beim Auslenken des Betätigungsorgans 2 um eine der Schaltstangen-Schwenkachsen 36, 37 ergeben.Thanks to this measure, the actuator pivot axes 24, 29 and the shift rod pivot axes 36, 37 can be operated independently. In addition, the restoring forces of the return means described below are coordinated so that an operation in particular the Betätigungsorgan- and the shift rod pivot axes 24, 29, 36, 37 independently without difficulty is possible by the restoring forces, which in the deflection of the
