Description
Druckluftsteuervorrichtung für die Kupplung von Kraftfahrzeugen Die Steuerung der Kupplung von Kraftfahrzeugen erfolgt bekanntlich normalerweise mittels einer mechanischen Übersetzung, die durch einen vom Fahrer bedienten Fußhebel betätigt wird.Pneumatic control device for the clutch of motor vehicles Die As is known, the clutch of motor vehicles is normally controlled by means of a mechanical translation, which is operated by a foot lever operated by the driver will.
Um bei sehr schweren Kraftfahrzeugen die Bedienung der Kupplung zu erleichtern, wurde bereits eine Druckmittelsteuervorrichtung vorgeschlagen, die aus einem Zylinder besteht, der über einen vom Kupplungsfußhebel des Fahrzeuges gesteuerten Verteiler aus einem Behälter mit Druckmittel beaufschlagt wird. Der Kolben dieses Zylinders rückt die Kupplung ein oder aus, wobei sowohl die mechanische Übertragung als auch die Steuerung des Druckverteilers durch den gleichen Kupplungsfußhebel bedient werden.In order to be able to operate the clutch in very heavy vehicles facilitate, a pressure medium control device has already been proposed that consists of a cylinder that is connected to one of the vehicle's clutch pedal controlled distributor is acted upon from a container with pressure medium. Of the Piston of this cylinder engages or disengages the clutch, both the mechanical Transmission and control of the pressure distributor through the same clutch pedal to be served.
Es ist ferner bekannt, einen durch den Kupplungsfußhebel zu betätigenden elektrischen Kontakt vorzusehen, dessen Aufgabe es ist, die Steuerung anderer elektrisch bedienter Vorrichtungen, wie z. B. die Steuerung des Wechselgetriebes; in Abhängigkeit von der Betätigung der Kupplung vorzunehmen. Die vorliegende Erfindung bezweckt, eine unmittelbare Vereinigung einer solchen Druckmittelsteuervorrichtung für Kraftfahrzeugkupplungen mit besagtem elektrischem Kontakt herzustellen, derart, daß die Betätigung dieses Kontaktes nicht durch den Kupplungsfußhebel, sondern unmittelbar durch den Kolben des Zylinders erfolgt, um dadurch eine bauliche Zusammenfassung der Steuerorgane zu erzielen. Dies bedeutet nicht nur eine wesentliche konstruktive Vereinfachung der Vorrichtung, sondern ermöglicht auch eine bedeutend größere Sicherheit im Betrieb.It is also known to be actuated by the clutch pedal to provide electrical contact, the task of which is to control others electrically operated devices such. B. the control of the gearbox; dependent on of operating the clutch. The present invention aims at a direct union of such a pressure medium control device for motor vehicle clutches with said electrical contact, such as that the actuation of this contact is not through the clutch pedal, but directly takes place through the piston of the cylinder, thereby creating a structural summary to achieve the tax organs. This doesn't just mean an essential constructive Simplification of the device, but also enables significantly greater security operational.
Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, daß außen am Kopf des mit Druckluft gespeisten Zylinders, dessen Kolben über geeignete Steuerorgane das Ein- bzw. Ausrücken der Kupplung bewirkt, ein Gehäuse angeordnet ist, in welchem der direkt durch besagten Kolben betätigte elektrische Kontakt untergebracht ist.The device according to the invention is characterized in that the outside at the head of the cylinder fed with compressed air, its pistons via suitable control elements causes the engagement or disengagement of the clutch, a housing is arranged in which the electrical contact operated directly by said piston is housed.
Zur besseren Verständlichmachung der Erfindung ist in den Zeichnungen eine beispielsweise Ausführungsform dargestellt, und zwar ist Fig. I ein Betriebsschema und die Fig. 2 und 3 ein axialer Längsschnitt bzw. eine Vorderansicht des Zylinders.For a better understanding of the invention is in the drawings an exemplary embodiment is shown, namely FIG. 1 is an operational diagram and Figures 2 and 3 are an axial longitudinal section and a front view of the cylinder, respectively.
Wie aus den Figuren hervorgeht, wird der Verteiler I mittels der Übersetzung 2 durch den Fußhebel 3 betätigt. Der Verteiler I wird über die am Anschluß 4' mündende Leitung 4 aus einem nicht dargestellten Druckluftbehälter gespeist. Weiter ist der Verteiler I mittels der Leitung 5 mit dem Zylinder 6 verbunden, dessen Kolben 7 mittels der in einer Gabel 9 endenden Stange 8 die das Ein- und Ausrücken der nicht dargestellten Kupplung bewirkenden Organe steuert. Außen am Zylinderkopf ist das Gehäuse Io angeordnet., welches durch die konkave äußere Wand II des Zylinderkopfes selbst sowie durch den Deckel 12 gebildet wird.As can be seen from the figures, the distributor I is by means of the translation 2 operated by the foot lever 3. The distributor I is via the terminal 4 'opening Line 4 fed from a compressed air tank, not shown. Next is that Distributor I connected by means of line 5 to cylinder 6, the piston 7 of which by means of the rod 8 ending in a fork 9, the engaging and disengaging of the not controls shown clutch causing organs. It's on the outside of the cylinder head Housing Io arranged. Which through the concave outer wall II of the cylinder head itself and is formed by the cover 12.
Die Wand II weist einen Sitz I3 auf, in welchem mittels der Schrauben I5 die Isolierplatte I4 befestigt ist, die die Kontaktplättchen I6 und I6' trägt, welche zusammen mit den Klemmen I7 und I7' fest mit der Isolierplatte I4 verbunden sind.The wall II has a seat I3 in which by means of the screws I5 the insulating plate I4 is attached, which carries the contact plates I6 and I6 ', which together with the terminals I7 and I7 'are firmly connected to the insulating plate I4 are.
Mit den Kontaktplättchen I6, I6' kann. die bewegliche Kontaktzunge I8 in Berührung kommen, welche mittels der Hülse I9 einstellbar -von der Stange 2o getragen wird, die dicht anliegend in der zylindrischen Bohrung 2I beweglich geführt ist, die in das Innere des Zylinders 6 mündet und in dem Vorsprung 22 der Wand II angeordnet ist. Die Stange 2o befindet sich unter der Wirkung der Feder 23 und steht mit dem Boden des Kolbens 7 in Berührung. Wenn der Kolben 7 seinen Hub durchführt, gestattet die in das Innere des Zylinders 6 eindringende Stange 2o infolge der Wirkung der Feder 23 die Berührung der Kontaktzunge I8 mit den Kontaktplättchen I6, I6'. Beim Rücklauf des Kolbens 7 wird diese Verbindnug unterbrochen. Im Gehäuse Io ist der Durchbruch 24 für die Zuführung des Verbindungskabels zu den Klemmen I7, I7' vorgesehen. Dieses Kabel führt zu dem elektrischen Steuerstromkreis für andere am Kraftfahrzeug angeordnete Vorrichtungen.With the contact plates I6, I6 'can. the movable contact tongue I8 come into contact, which can be adjusted by means of the sleeve I9 -from the rod 2o is carried, which fits tightly in the cylindrical bore 2I movable is guided, which opens into the interior of the cylinder 6 and in the projection 22 of the Wall II is arranged. The rod 2o is under the action of the spring 23 and is in contact with the bottom of the piston 7. When the piston 7 is his Performs stroke, the penetrating rod into the interior of the cylinder 6 allows 2o as a result of the action of the spring 23, the contact of the contact tongue I8 with the contact plate I6, I6 '. When the piston 7 returns, this connection is interrupted. In the case Io is the opening 24 for the feed of the connecting cable to the terminals I7, I7 'provided. This cable leads to the electrical control circuit for other devices arranged on the motor vehicle.
Die erfindungsgemäße Vorrichtung kann zwei Betriebsaufgaben erfüllen: a) Der Zylinder 6 kann einfach als Hilfsvorrichtung der mechanischen Steuerung der Kupplung dienen. Wie aus Fig.I hervorgeht, werden in diesem Fall sowohl die mechanische Steuerübersetzung als auch der Druckluftverteiler gleichzeitig durch den Fußhebel 3 betätigt.The device according to the invention can fulfill two operational tasks: a) The cylinder 6 can simply be used as an auxiliary device for the mechanical control of the Serve clutch. As can be seen from Fig.I, both the mechanical Control ratio and the compressed air distributor at the same time through the foot lever 3 actuated.
b) Der Zylinder 6 kann als alleiniges Druckluftsteuerorgan für die Kupplung dienen. Hierfür genügt es, den mechanischen Übersetzungsteil, der in Fig. I durch die strichpunktierte Linie 8' angedeutet ist, zu beseitigen.b) The cylinder 6 can be used as the sole compressed air control element for the Serve clutch. For this it is sufficient to use the mechanical translation part, which is shown in Fig. I is indicated by the dash-dotted line 8 'to eliminate.
