Aus der
Bei Kupplungssystemen, die auf einem Clutch-by-wire-Prinzip beruhen, erfolgt das Betätigen einer Kupplung durch einen Elektromotor, der unter anderem auch von einem, durch den Fahrer betätigtes Kupplungspedal geregelt wird. Der Fahrer soll allerdings beim Ein- und Auskuppeln den gleichen Kraft-Weg-Verlauf am Pedal spüren, wie bei einem konventionellen Ausrücksystem. Der Geberzylinder des konventionellen Ausrücksystems soll hierbei durch ein Bauteil ersetzt werden, welches den gleichen Kraft-Weg-Verlauf wie das konventionelle Ausrücksystem auf das Kupplungspedal erzeugt. In clutch systems based on a clutch-by-wire principle, a clutch is actuated by an electric motor which is also controlled, inter alia, by a driver-operated clutch pedal. The driver should, however, feel the same force-displacement curve on the pedal when engaging and disengaging, as in a conventional release system. The master cylinder of the conventional release system is to be replaced by a component which generates the same force-displacement curve as the conventional release system on the clutch pedal.
Es ist ein Pedalkraftsimulator bekannt, bei welchem eine, vom Fahrpedal kommende translatorische Bewegung in eine rotatorische Bewegung umgewandelt wird. Mit dieser Drehbewegung wird ein als Schraubenfeder ausgebildeter Energiespeicher um seine Achse auf Biegung beansprucht, wodurch in Abhängigkeit vom Pedalweg eine Kraft auf das Fahrpedal wirkt. Die Kraft die dabei auf die Translations-Rotationseinheit wirkt ist sehr groß.A pedal force simulator is known in which a translational movement coming from the accelerator pedal is converted into a rotational movement. With this rotational movement designed as a helical spring energy storage is claimed around its axis to bending, which acts as a function of the pedal travel a force on the accelerator pedal. The force acting on the translational rotation unit is very large.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Kraftsimulation an einem Betätigungselement eines Fahrzeuges anzugeben, bei welcher die auf die Translations-Rotationseinheit wirkende Kraft reduziert wird.The invention has for its object to provide a device for force simulation on an actuating element of a vehicle, in which the force acting on the translational rotation unit force is reduced.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Energiespeicher aus mindestens einer Schraubenfeder und mindestens einer Druckfeder gebildet ist. Dies hat den Vorteil, dass durch die Druckfeder eine Vorlast am Pedal eingestellt wird, wodurch die von der Schraubenfeder aufzubringenden Kräfte, die zur Erzeugung der gewünschten Kraft am Betätigungselement notwendig sind, reduziert werden. Dies hat zur Folge, dass die Translations-Rotationseinheit weniger belastet wird.According to the invention the object is achieved in that the energy storage is formed from at least one coil spring and at least one compression spring. This has the advantage that a preload on the pedal is adjusted by the compression spring, whereby the forces to be applied by the coil spring, which are necessary for generating the desired force on the actuating element, are reduced. This has the consequence that the translational rotation unit is less stressed.
Vorteilhafterweise umschließt die Schraubenfeder die Druckfeder. Durch die parallele Erstreckung von Schrauben und Druckfeder wird Bauraum gespart, so dass die Vorrichtung nicht mehr Platz benötigt als ein Geberzylinder eines konventionellen Aktorsystems. Advantageously, the coil spring surrounds the compression spring. Due to the parallel extension of screws and compression spring space is saved, so that the device does not require more space than a master cylinder of a conventional actuator system.
In einer Variante weist die Translations-Rotations-Einheit eine Drehhülse auf, die ein, mit dem Betätigungselement in einer Wirkverbindung stehendes Verstellelement umfasst, wobei sich die mindestens eine Schraubenfeder außen an der Drehhülse abstützt, während die mindestens eine Druckfeder in die Drehhülse eingreift und sich an dem, durch die Drehhülse durchgreifenden Verstellelement abstützt. Durch die Abstützung der Druckfeder an dem Verstellelement, wird die Vorspannung an dem Fahrpedal einfach realisiert, da es über das Betätigungselement direkt mit dem Fahrpedal verbunden ist. In a variant, the translation-rotation unit has a rotary sleeve, which comprises a, with the actuating element in an operative connection adjusting element, wherein the at least one coil spring is externally supported on the rotary sleeve, while the at least one compression spring engages in the rotary sleeve and on which, by the rotary sleeve by cross-adjusting element is supported. By supporting the compression spring on the adjusting element, the bias voltage to the accelerator pedal is easily realized, since it is connected via the actuator directly to the accelerator pedal.
In einer Ausgestaltung ist die Translations-Rotations-Einheit über je ein Lager von einer schraubenförmig ausgebildeten Kontur geführt, wobei die Lager aufeinander abrollen und die schraubenförmig verlaufende Kontur eine vorgegebene Steigung aufweist. Mittels dieser schraubenförmig ausgebildeten Kontur wird die translatorische Bewegung des Betätigungselementes in die rotatorische Bewegung umgewandelt, mittels welcher der Energiespeicher in Form der Schraubenfeder aufgedreht, d.h. tordiert, wird. Durch diese Anordnung wird auf die Drehhülse ein Drehmoment proportional zum Torsionswinkel der Schraubenfeder ausgeübt. In one embodiment, the translation-rotation unit is guided over a respective bearing of a helically shaped contour, wherein the bearings roll on each other and the helical contour has a predetermined slope. By means of this helically shaped contour, the translatory movement of the actuating element is converted into the rotational movement, by means of which the energy store in the form of the helical spring turned up, i. is twisted, will. By this arrangement, a torque proportional to the torsion angle of the coil spring is exerted on the rotary sleeve.
In einer Ausführungsform verläuft die Steigung der schraubenförmig verlaufenden Kontur unstetig. Auf diese Weise wird ein gewünschter Kraft-Weg-Verlauf an der Vorrichtung eingestellt.In one embodiment, the pitch of the helical contour is discontinuous. In this way, a desired force-displacement curve is set on the device.
Um am Fahrpedal das gleiche Gefühl, wie bei einem konventionellen System einzustellen, ist die Steigung der schraubenförmig verlaufenden Kontur zu Beginn des Betätigungsweges des Betätigungselementes steiler ausgebildet als gegen Ende des Betätigungsweges. Je steiler die Steigung der schraubenförmig ausgebildeten Kontur ist, desto größer wird das an der Translations-Rotations-Einheit anliegende Drehmoment in eine axiale Kraft umgewandelt, die dann der Nutzer an dem Betätigungselement wahrnimmt. In order to set the same feeling on the accelerator pedal, as in a conventional system, the slope of the helical contour at the beginning of the actuating travel of the actuating element is formed steeper than the end of the actuation path. The steeper the slope of the helically shaped contour, the greater the torque applied to the translation-rotation unit is converted into an axial force, which then perceives the user on the actuator.
In einer Ausführungsform ist die schraubenförmig ausgebildete Kontur innen an der Drehhülse ausgebildet. Da sich die Kontur entlang des Abrollpunktes des Lagers zur Drehhülse erstreckt, rotiert nur die Drehhülse. In one embodiment, the helically shaped contour is formed inside the rotary sleeve. As the contour along the Unwinding point of the bearing extends to the rotary sleeve, rotates only the rotary sleeve.
Vorteilhafterweise ist jedes der beiden aufeinander abrollenden Lager auf einem Stift gelagert, wobei ein Lager auf der in der Drehhülse positionierten schraubenförmigen Kontur abrollt, während das andere Lager an dem Gehäuse entlang einer axial verlaufenden Bahn abrollt. Dies hat den Vorteil, dass eine Verdrehsicherung für das Verstellelement eingestellt wird.Advantageously, each of the two successive rolling bearings is mounted on a pin, with one bearing rolling on the helical contour positioned in the rotary sleeve, while the other bearing rolls on the housing along an axially extending path. This has the advantage that an anti-rotation for the adjustment is set.
In einer anderen Ausführungsform ist die schraubenförmig ausgebildete Kontur an einem, die Drehhülse umfassenden Gehäuse ausgebildet. In another embodiment, the helically formed contour is formed on a, the rotary sleeve comprehensive housing.
In einer Weiterbildung sind jedes der beiden aufeinander abrollenden Lager auf einem Stift gelagert, wobei ein Lager auf der, an dem Gehäuse ausgebildeten schraubenförmigen Kontur abrollt, während das andere Lager auf der Drehhülse abrollt. Dadurch werden zunächst beide Lager bei einer Bewegung des Betätigungselementes in axialer Richtung verschoben. Die schraubenförmige Kontur drückt dabei das erste Lager in radialer Richtung gegen das zweite Lager, welches wiederum auf die Drehhülse drückt, was wiederum auf die Schraubfeder führt, wodurch diese tordiert. In a further development, each of the two successive rolling bearings are mounted on a pin, wherein a bearing rolls on the, formed on the housing helical contour, while the other camp rolls on the rotary sleeve. As a result, first both bearings are displaced in a movement of the actuating element in the axial direction. The helical contour presses the first bearing in the radial direction against the second bearing, which in turn presses on the rotary sleeve, which in turn leads to the coil spring, causing them twisted.
In einer weiteren Ausgestaltung ist die Translations-Rotations-Einheit über ein Lager von der schraubenförmig ausgebildeten Kontur geführt, wobei die schraubenförmig verlaufende Kontur eine vorgegebene Steigung aufweist, wobei an dem Gehäuse eine Gleitschiene positioniert ist, welche mit dem Verstellelement eine Reibstelle bildet. Das Drehmoment, das die um ihre Achse auf Biegung beanspruchte Schraubenfeder erzeugt, stützt sich an einer linearen Gleitführung am Gehäuse ab, wodurch in Abhängigkeit vom Drehmoment eine Hysterese erzeugt wird. Durch diese Reibstelle wird eine hinreichend große Hysterese eingestellt, um die Pedalkraft realistisch zu gestalten.In a further embodiment, the translational-rotational unit is guided via a bearing of the helically shaped contour, wherein the helically extending contour has a predetermined slope, wherein on the housing a slide rail is positioned, which forms a friction point with the adjusting element. The torque generated by the helical spring, which is bent around its axis, is supported by a linear sliding guide on the housing, which produces hysteresis depending on the torque. By this friction point a sufficiently large hysteresis is set to make the pedal force realistic.
Vorteilhafterweise weist das Verstellelement zur Bildung der Reibstelle eine Kontaktfläche auf, welche sich auf der Gleitschiene bewegt. Die so erzeugte Hysterese steigt in Abhängigkeit mit der erzeugten Pedalkraft an.Advantageously, the adjusting element for forming the friction point has a contact surface which moves on the slide rail. The hysteresis thus generated increases depending on the generated pedal force.
In einer Weiterbildung hängt ein Reibkoeffizient der Reibstelle von einem Material der Kontaktfläche und der Gleitschiene ab. Durch die Wahl des Materials lässt sich der Reibkoeffizient und somit die Größe der Hysterese beliebig einstellen.In a further development, a friction coefficient of the friction point depends on a material of the contact surface and the slide rail. By choosing the material, the friction coefficient and thus the size of the hysteresis can be set as desired.
