Description

Elektrisches Steuerventil für druckluftgesteuerte Bremsen und Reibungskupplungen. Zweck der vorliegenden Erfindung ist ein elektrisch gesteuertes Ventil, das die Luftpressung in den Druckzylindern proportional dem Ausschlage des Steuerhebels in beliebiger Größe zwischen Null und Maximum einstellt und damit eine leichte und vollkommene Regelbarkeit der Brems- und Kupplungskräfte erzielt.Electric control valve for brakes and friction clutches controlled by compressed air. The purpose of the present invention is an electrically controlled valve that the Air pressure in the pressure cylinders proportional to the deflection of the control lever adjusts in any size between zero and maximum and thus a light and Complete controllability of the braking and clutch forces is achieved.

Das Mittel besteht in der Hauptsache darin, daß ein - Steuerschieber zum Ein- und Auslassen der Druckluft unter dem Einfiusse der Kraft eines kleinen Elektromotors und unter dem Drucke des Kolbens eines Hilfszylinders steht, der mit dem Druckzylinder der Bremse oder Kupplung verbunden ist, und daß das Drehmoment des Motors durch einfache Veränderung der Stromstärke mittels eines Schalters einstellbar ist.The main thing is that a - control slide to let in and out the compressed air under the influence of the force of a small one Electric motor and is under the pressure of the piston of an auxiliary cylinder, which is with the pressure cylinder of the brake or clutch is connected, and that the torque of the motor can be set by simply changing the amperage using a switch is.

Das in Abb. i dargestellte Ausführungsbeispiel dient für Bremsen und Kupplungen, bei denen die Luftpressung im Druckzylinder proportional der Motorstromstärke zunimmt, wie das Druckdiagramm in Abb. z zeigt. Das Ausführungsbeispiel nach Abb. 3 ist dagegen bestimmt für Bremsen und Kupplungen, deren Kraft nach_ Abb. q. mit zunehmender Stromstärke abnimmt.The embodiment shown in Fig. I is used for brakes and Couplings in which the air pressure in the pressure cylinder is proportional to the motor current increases, as the pressure diagram in Fig. z shows. The embodiment according to Fig. 3, on the other hand, is intended for brakes and clutches, the force of which is shown in Fig. Q. with increasing amperage decreases.

Bei der Ausführung nach Abb. i befindet sich in dem Ventilgehäuse i, das an die vom Druckluftbehälter kommende Leitung a angeschlossen ist, der Muschelschieber 3, der je nach seiner Stellung den zum Bremszylinder q. führenden Kanal 5 mit dem Druckluftbehälter mit dein Auslaßkanal 6 verbindet odex gegen beide absperrt. Auf der Schieberstange 7 sitzen die luftdichten Kolben 8 und 9 von gleichem Durchmesser, so daß der im Gehäuse herrschende Luftbehälterdrack keine Verstellkraft auf den Schieber ausübt. Durch den Kanal i o steht der Kolben 8 unter der im Bremszylinder jeweilig vorhandenen Luftpressung. Dieser Kolbenkraft entgegen wirkt die Kraft des Motors i i, der durch .ein Zahnradgetriebe gegen den Kolben 9 drückt. In der Mittelstellung des Schiebers, in der bei;de Kräfte sich das Gleichgewicht halten, ist der zum Bremszylinder führende Kanal gegen Luftbehälter und Außenluft abgeschlossen, so daß im Bremszylinder jede zwischen Null und Luftbehälterdruck liegende Pressung herrschen kann, die .eindeutig bestimmt wird durch die Kraft bzw. Stromstärke des Motors. Ist z. B. die Stromstärke J,, und die Kraft des Motors gleich Null, so muß auch der Druck P., im Bremszylinder Null sein, da der Schieber durch den Kolben in die Auslaßstellung bewagt wird. Erhält der Motor dagegen Strom, so öffnet der Schieber den Einlaß und läßt so viel Druck üi den Bremszylinder treten, bis die Kolbenkraft tles Hilfszylinders die Motorkraft überwindet und den Schieber in die Abschlußstellung zurückbewegt. Wird die Stromstärke konstant auf einen bestimmten Wert gehalten, so hält das Steuerventil! den Druck im Bremszylinder auch bei etwaigen Undichtigkeiten auf den eindeutig hestimmten Wert, indem die beiden Kräfte von Motor und Hilfskolben selbsttätig durch Einlassen oder Auslassen den Druck regeln und den Schieber in die Abschlußstellung zurückbringen.In the version according to Fig. I is located in the valve housing i, which is connected to line a coming from the compressed air tank, the mussel valve 3, which depending on its position, to the brake cylinder q. leading channel 5 with the Compressed air tank with your outlet channel 6 connects odex shut off against both. on the airtight pistons 8 and 9 of the same diameter sit on the slide rod 7, so that the prevailing air tank rack in the housing no adjusting force on the Pusher exercises. The piston 8 is below that in the brake cylinder through the channel i o respective existing air pressure. This piston force is counteracted by the force of the Motor i i, which presses against piston 9 through .ein gear transmission. In the middle position of the slide, in which the two forces are in equilibrium, is that of the brake cylinder leading channel closed against air reservoir and outside air, so that in the brake cylinder any pressure lying between zero and air tank pressure can prevail, which is unambiguous is determined by the force or amperage of the motor. Is z. B. the amperage J ,, and the power of the motor is zero, so must the pressure P., in the brake cylinder Must be zero, as the slide is moved into the outlet position by the piston. Receives if the motor, on the other hand, has current, the slide opens the inlet and allows so much pressure üi press the brake cylinder until the piston force of the auxiliary cylinder exceeds the motor force overcomes and moves the slide back into the final position. Will the amperage kept constant at a certain value, the control valve holds! the pressure in the brake cylinder even if there are any leaks on the clearly hestimmten Value, by the two forces of the engine and auxiliary piston automatically by letting in or Release Regulate the pressure and return the slide to the closed position.

Bei dem zweiten Ausführungsbeispiel nach Abb. 3 steht der Muschelschieber 3 unter dem Einfluß von drei Kräften, und zwar unter einer konstanten Kraft der Druckluftbehälterpressung und unter den beiden veränderlichen Kräften vom Motor und Bremszylinderdruck. Der an dem Muschelschieber angreifende Kolben 8 ist mit dem Zahnradgetriebe. des Motors i i verbunden. Diese Ausführung unterscheidet sich in der Wirkung von der ersten nur dadurch, daß die Luftpressung, wie Diagramm in Abb. q. zeigt, dem Behälterdruck gleich wird, wenn die Stromstärke Null ist, und sie wird Null, wenn die Stromstärke am größten ist.In the second embodiment according to Fig. 3, the mussel slide is in place 3 under the influence of three forces, namely under a constant force of Compressed air tank pressure and under the two variable forces from the engine and brake cylinder pressure. The piston 8 engaging the mussel slide is with the gear transmission. of the engine i i connected. This version is different in the effect of the first only by the fact that the air pressure, as shown in the diagram in Fig.q. shows the tank pressure becomes equal when the current is zero, and it becomes zero when the current is greatest.
