Description
Schaltvorrichtung für Kraftfahrzeuge Um die Umschaltung des Getriebes von Kraftfahrzeugen zu erleichtern, ist bereits vorgeschlagen worden, den Schaltvorgang elektromagnetisch zu steuern. Die bekannten Anordnungen dieser Art lösen die Aufgabe nur in sehr unvollkommener Weise. Teils beschränken sie sich auf die elektromagnetische Schaltung des Getriebes, so daß die Kupplung nach wie vor durch einen Fußhebel eingestellt werden muß, teils verwenden sie nicht einfach zu bedienende Stromschalter, so daß leicht Verwechselungen bei der Wahl der Schaltung eintreten können.Switching device for motor vehicles To switch the transmission of motor vehicles has already been proposed to facilitate the shifting process to be controlled electromagnetically. The known arrangements of this type solve the problem only in a very imperfect way. Partly they are limited to the electromagnetic Shifting the gearbox so that the clutch is still set by a foot lever must be, partly they do not use easy-to-use power switches, so that It is easy to get confused when choosing the circuit.
Nach der Erfindung wird eine sehr einfach zu bedienende und auch baulich einfache Anordnung durch Verwendung einer Druckknopfsteuerung erreicht, die derart wirkt, daß durch Niederdrücken eines Knopfes zuerst der Elektromagnet für die Kupplung und dann derjenige für das betreffende Schaltglied erregt wird, wobei die Erregung des Elektromagneten für die Kupplung sich selbsttätig wieder aufhebt.According to the invention, it is very easy to use and also structurally simple arrangement achieved by using a push button control, such acts that by pressing a button first the electromagnet for the clutch and then the one for the relevant switching element is excited, the excitation of the electromagnet for the clutch cancels itself again.
In der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt, und zwar zeigen: Abb. r die gesamte Schaltordnung und Abb. 2 einen Druckknopf in größerem Maßstabe.An embodiment of the invention is shown schematically in the drawing shown, namely: Fig. r shows the entire circuit arrangement and Fig. 2 a Push button on a larger scale.
Das Getriebe besteht in bekannter Weise aus der Motorwelle a mit der Kupplung b und den axial verschiebbaren Schalträdern c, d, e, f sowie der Kardanwelle g mit den Gegenrädern h, i, k,1. Ferner gehören dazu die Umkehrräder m und n für den Rückwärtsgang. Die Räder e, k bilden den ersten Vorwärtsgang, die Räder d, i den zweiten Gang und die Räder c, h den dritten Gang. Aus der Zeichnung ist ersichtlich, daß die verschiedenen Schaltungen durch axiale Verschiebung der Gestänge o und p aus der gezeichneten Mittelstellung nach rechts oder links erfolgen kann. Diese Verschiebung wird durch die Elektromagnete q, bis 'q4 bewirkt, sobald die zugehörigen Druckknöpfe rl bis r4 bewegt werden. Die Knöpfe r1 bis r4 sind so miteinander verriegelt, daß beim Eindrücken eines Knopfes ein vorher etwa eingeschaltet gewesener Knopf selbsttätig ausspringt. Diese bekannte Einrichtung ist in der Zeichnung fortgelassen worden. Jeder Druckknopf r besitzt, wie Abb. 2 zeigt, eine Kontaktnase s, welche beim Niederdrücken des Knopfes zunächst mit der Kontaktfeder t in Berührung kommt, wodurch der Magnet a für die Kupplung erregt wird. Sobald der Knopf r in seiner tiefsten Stellung angekommen ist und den Kontakt v für einen der Elektromagnete q geschlossen hat, ist der Kontakt zwischen s und t wieder aufgehoben, so daß die Kupplung b wieder einfallen kann.The transmission consists in a known manner of the motor shaft a with the clutch b and the axially displaceable shift gears c, d, e, f as well as the cardan shaft g with the mating gears h, i, k, 1. This also includes the reversing gears m and n for reverse gear. The wheels e, k form the first forward gear, the wheels d, i the second gear and the wheels c, h the third gear. From the drawing it can be seen that the various switching operations can be carried out by axially displacing the rods o and p from the center position shown to the right or left. This shift is effected by the electromagnets q to q4 as soon as the associated pushbuttons rl to r4 are moved. The buttons r1 to r4 are locked together so that when a button is pressed, a button that was previously switched on automatically pops out. This known device has been omitted from the drawing. As Fig. 2 shows, each push button r has a contact lug s which, when the button is depressed, first comes into contact with the contact spring t, as a result of which the magnet a for the clutch is excited. As soon as the button r has reached its lowest position and has closed the contact v for one of the electromagnets q , the contact between s and t is canceled again, so that the clutch b can engage again.
Die Wirkungsweise der Einrichtung ist wie folgt: Will man z. B. den ersten Vorwärtsgang einschalten, dann drückt man den Knopf r2 nieder. Dadurch wird zunächst der Kontakt zwischen s und t geschlossen und die Kupplung b ausgerückt. Dann wird durch Schließen des Kontaktes v der Magnet q2 erregt und damit die Schaltung herbeigeführt; gleichzeitig wird der Kontakt zwischen s und t wieder unterbrochen, so daß die Kupplung b wieder einfällt.The operation of the device is as follows: If you want z. B. the switch on first forward gear, then press button r2. This will initially the contact between s and t is closed and clutch b is disengaged. Then, by closing the contact v, the magnet q2 is excited and thus the circuit brought about; at the same time the contact between s and t is interrupted again, so that the clutch b engages again.
