Definitions
- the invention relates to an actuating device for a motor vehicle clutch according to the preamble of claim 1.
- the object of the invention is to provide a fastening device of the type characterized in the preamble of claim 1, which causes a steep increase in power assistance after the dead center position has been exceeded.
- the stored spring force from the tension spring acts as a support torque on the pedal, in particular when it is actuated.
- This support causes a steep response after passing through the dead center position, which is essentially achieved by the arrangement and mounting of the push rod and the tension spring. So the push rod can pivot around the bearing point on the lever arm of the pedal and the spring around its fixed point on the body with the push rod. Even with a small pivoting angle of the pedal, this advantageously has a leaping effect magnifying support moment.
- the actuating device achieves a quick response behavior with a steeply increasing support torque and good tunability when using a few simple components.
- the actuating device for a clutch consists essentially of a clutch pedal 1 with pedal plate 2, which is articulated about a pivot axis 3 on the vehicle body 4.
- the pedal 1 has a protruding lever arm 5 which is connected via a bearing point 6 formed by a pivot bearing to a push rod 7, on which a tension spring 10 articulated on the vehicle body 4 in a fixed point 9 is held in an opposite bearing 8.
- the push rod 7 consists of a U-shaped bracket, the legs 13, 14 of which each have the bearings 6 and 8.
- the spring 10 is arranged embedded between these legs 13, 14.
- the bearing 6 of the push rod 7 on the lever arm 5 is arranged with the smallest possible distance a from the fixed point 9 of the tension spring 10. As can be seen in more detail in FIG. 1, the distance a corresponds approximately to half the width b of the lever arm 5.
- the push rod 7 pivots with the pedal 1 in the direction of the arrow 15 around the bearing 6 and the tension spring 10 around the fixed point 9, which contracts during this process.
- position B of the push rod 7 the end position of the pedal 1 is reached, the support lever arm having reached its maximum value and an action line 16 extending at an acute angle ⁇ to the action line 11.
- FIG. 3 shows the course of the line of action between the pedal position when the clutch is engaged and the clutch is disengaged.
- the line of action 11 with the clutch disengaged causes a lever arm 17, by means of which a restoring moment of the pedal 1 for holding in the rest position is generated.
- the pedal 1 is actuated in the direction of the arrow 15, the line of action 11 passes through the bearing 3 of the pedal 1 and establishes a dead center position with a line of action 11a.
- an action line 16a After passing through this position, for example, an action line 16a generates a support moment for the pedal 1 via the lever arm 18, which increases depending on the pivoting angle of the pedal 1 in the direction of the arrow 15 and can reach its maximum value with the action line 16 and the lever arm 19.
- the course of the support torque over the pedal travel results from the coordination of the kinematics and the spring characteristics, so that, as described above, the maximum value can also be reached before the line of action and with the line of action 16 there is even a lower support torque.

Abstract
Description
Die Erfindung bezieht sich auf eine Betätigungseinrichtung für eine Kraftfahrzeugkupplung nach dem Oberbegriff des Anspruchs 1.The invention relates to an actuating device for a motor vehicle clutch according to the preamble of claim 1.
Aus der DE-AS 11 52 896 ist eine Betätigungseinrichtung für Kraftfahrzeugkupplungen bekannt, bei der das Pedal unter der Wirkung einer vorgespannten Zugfeder steht, die je nach der Lage des Pedals über eine Druckstange eine Kraftunterstützung bewirkt. Bei in Ruhelage befindlichem Kupplungspedal übt die Feder eine das Pedal in dieser Lage haltende Rückstellkraft aus und bei Betätigen des Pedals sowie nach Überschreiten einer Totpunktstellung gibt die Feder eine die Fußkraft unterstützende Kraft ab. Durch die Festlegung des einen Endes der Druckstange mit der Feder am Fahrzeugaufbau sowie des relativ großen Abstands dieser Lagerpunkte zum vorderen Lagerpunkt der Druckstange am Pedal ergibt sich bei einem relativ großem Schwenkwinkel des Pedals durch den sich bildenden Hebelarm eine Kraftunterstützung, die nach Überschreiten der Totpunktstellung nur schwach ansteigt.From DE-AS 11 52 896 an actuating device for motor vehicle clutches is known in which the pedal is under the action of a prestressed tension spring which, depending on the position of the pedal, causes a force support via a push rod. When the clutch pedal is in the rest position, the spring exerts a restoring force that holds the pedal in this position, and when the pedal is actuated and after a dead center position is exceeded, the spring releases a force that supports the foot force. By defining one end of the push rod with the spring on the vehicle body and the relatively large distance of these bearing points from the front bearing point of the push rod on the pedal, a force support results from the lever arm that is formed at a relatively large pivoting angle of the pedal arm, which only occurs after the dead center position has been exceeded increases slightly.
Aufgabe der Erfindung ist es eine Befestigungseinrichtung der im Oberbegriff des Anspruchs 1 gekennzeichneten Art zu schaffen, die nach Überschreiten der Totpunktstellung einen steilen Anstieg der Kraftunterstützung bewirkt.The object of the invention is to provide a fastening device of the type characterized in the preamble of claim 1, which causes a steep increase in power assistance after the dead center position has been exceeded.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved according to the invention by the characterizing features of claim 1. The dependent claims contain further advantageous features.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß die gespeicherte Federkraft aus der Zugfeder als Unterstützungsmoment auf das Pedal insbesondere dann wirkt, wenn es betätigt wird. Diese Unterstützung bewirkt nach Durchlaufen der Totpunktstellung ein steiles Ansprechverhalten, was im wesentlichen durch die Anordnung und Lagerung der Druckstange sowie der Zugfeder erzielt wird. So kann die Druckstange um den Lagerpunkt am Hebelarm des Pedals und die Feder um ihren aufbauseitigen Festpunkt mit der Druckstange verschwenken. Dies bewirkt schon bei einem geringen Verschwenkwinkel des Pedals in vorteilhafter Weise ein sich sprunghaft vergrößerndes Unterstützungsmoment. Diese Wirkung wird noch verstärkt durch die im geringstmöglichen Abstand zueinander angeordneten Lagerpunkte der Druckstange am Hebelarm und der Zugfeder am Fahrzeugaufbau 10, daß die Kraftwirkungslinie, deren Verlauf durch die Lagerpunkte vorgegeben ist, sich entsprechend dem Verschwenkwinkel des Pedals ausbildet und ein größerer Hebelarm einstellt.The main advantages achieved by the invention are that the stored spring force from the tension spring acts as a support torque on the pedal, in particular when it is actuated. This support causes a steep response after passing through the dead center position, which is essentially achieved by the arrangement and mounting of the push rod and the tension spring. So the push rod can pivot around the bearing point on the lever arm of the pedal and the spring around its fixed point on the body with the push rod. Even with a small pivoting angle of the pedal, this advantageously has a leaping effect magnifying support moment. This effect is further enhanced by the bearing points of the push rod on the lever arm and the tension spring on the
Zusammenfassend wird durch die Betätigungseinrichtung ein schnelles Ansprechverhalten mit einem steil ansteigenden Unterstützungsmoment und eine gute Abstimmbarkeit bei Verwendung von wenigen, einfachen Bauteilen erzielt.In summary, the actuating device achieves a quick response behavior with a steeply increasing support torque and good tunability when using a few simple components.

Die Betätigungseinrichtung für eine nicht näher dargestellte Kupplung besteht im wesentlichen aus einem Kupplungspedal 1 mit Pedalplatte 2, welches um eine Schwenkachse 3 am Fahrzeugaufbau 4 angelenkt ist. Das Pedal 1 weist einen hinausragenden Hebelarm 5 auf, der über ein von einem Schwenklager gebildeten Lagerpunkt 6 mit einer Druckstange 7 verbunden ist, an welcher in einem gegenüberliegenden Lager 8 eine am Fahrzeugaufbau 4 in einem Festpunkt 9 angelenkte Zugfeder 10 gehalten ist.The actuating device for a clutch, not shown in detail, consists essentially of a clutch pedal 1 with
Wie Fig. 1 näher zeigt, nimmt die Druckstange 7 in der ausgerückten Stellung A der Kupplung eine solche Lage ein, daß eine Kraftwirkungslinie 11, welche durch die Lager 6 und 8 sowie durch den Festpunkt 9 der Feder 10 verläuft, eine Rückstellung des Pedals 1 in Pfeilrichtung 12 bewirkt.1 shows, in the disengaged position A of the clutch, the
Die Druckstange 7 besteht aus einem U-förmigen Bügel, dessen Schenkel 13, 14 jeweils die Lager 6 und 8 aufweisen. Zwischen diesen Schenkeln 13, 14 ist die Feder 10 eingebettet angeordnet.The
Das Lager 6 der Druckstange 7 am Hebelarm 5 ist mit einem geringstmöglichen Abstand a zum Festpunkt 9 der Zugfeder 10 angeordnet. Wie in Fig. 1 näher zu erkennen ist, entspricht der Abstand a etwa der halben Breite b des Hebelarmes 5.The bearing 6 of the
Beim Betätigen des Kupplungspedals 1 aus der Grundstellung gemäß Fig. 1 in Pfeilrichtung 15 zum Einrücken der Kupplung wird die Lage der Kraftwirkungslinie 11 verändert, wodurch sich ein vergrößerndes Unterstützungsmoment auf das Pedal 1 einstellt.When the clutch pedal 1 is actuated from the basic position according to FIG. 1 in the direction of
Wie Fig. 2 zeigt, verschwenkt sich mit dem Pedal 1 in Pfeilrichtung 15 auch die Druckstange 7 um das Lager 6 sowie die Zugfeder 10 um den Festpunkt 9, welche sich bei diesem Vorgang zusammenzieht. In der Stellung B der Druckstange 7 ist die Endstellung des Pedals 1 erreicht, wobei der Unterstützungshebelarm seinen maximalen Wert erreicht hat und eine Wirkungslinie 16 unter einem spitzen Winkel α zur Wirkungslinie 11 verläuft.As shown in FIG. 2, the
In Fig. 3 ist der Verlauf der Wirkungslinie zwischen der Pedalstellung bei eingerückter Kupplung und ausgerückter Kupplung gezeigt. Die Wirkungslinie 11 bei ausgerückter Kupplung bewirkt einen Hebelarm 17, durch den ein Rückstellmoment des Pedals 1 zur Haltung in der Ruhelage erzeugt wird. Beim Betätigen des Pedals 1 in Pfeilrichtung 15 durchläuft die Wirkungslinie 11 das Lager 3 des Pedals 1 und stellt eine Totpunktstellung mit einer Wirkungslinie 11a her. Nach Durchlaufen dieser Stellung erzeugt z.B. eine Wirkungslinie 16a über den Hebelarm 18 ein Unterstützungsmoment des Pedals 1, das in Abhängigkeit von dem Verschwenkwinkel des Pedals 1 in Pfeilrichtung 15 anwächst und seinen Höchstwert mit der Wirkungslinie 16 und dem Hebelarm 19 erreichen kann. Der Verlauf des Unterstützungsmomentes über dem Pedalweg ergibt sich aus der Abstimmung der Kinematik und der Federkennwerte, so daß wie vorstehend beschrieben, der Höchstwert auch schon vor der Wirkungslinie erreichbar ist und mit der Wirkungslinie 16 sich sogar ein geringeres Unterstützungsmoment einstellt.3 shows the course of the line of action between the pedal position when the clutch is engaged and the clutch is disengaged. The line of
Bei einem Verschwenken des Pedals 1 in Pfeilrichtung 15 bewegt sich die Druckstange 7 in Abhängigkeit von dieser Pedalbewegung auf einem Bogen 20 in der Weise, daß die Wirkungslinie immer durch die Lagerpunkte 6, 8 und 9 verläuft. Bei einem "Loslassen" des Pedals 1 und einem Verschwenken in Pfeilrichtung 12 stellt sich das Pedal 1 sowie die Druckstange 7 mit Feder 10 in die Grundstellung A zurück.When the pedal 1 is pivoted in the direction of the
