Abstract

The description relates to a control element consisting of (n) solenoid valves (1, 2, 11, 12, 31-33) which can be brought into more than (n) three different combinations of positions including the initial position via only (n) control lines (4a, 4b, 14a, 14b, 1'-3'). To this end, a diode (3, 13, 15, 34) is connected in series with at least one valve and the control lines (4a, 4b, 14a, 14b, 1'-3') are connected to the d.c. source in different pole arrangements for the other two combinations of positions.

Description

Stellglied Actuator
Stand der TechnikState of the art
Es ist z.B. aus der DE-OS 1655 318 bekannt, das Einlaß- und das Auslaßven¬ til eines ABS einseitig parallel an Masse zu legen und das Einlaßventil mit seiner anderen Seite mit einem ersten Ausgang eines Ansteuergerätes und das Auslaßventil mit einem zweiten Ausgang des Ansteuergerätε zu verbinden. Zwischen den beiden Ansteuerleitungen ist eine Diode derart eingeschaltet, daß ein Signal auf der vom ersten Ausgang kommenden Ansteuerleitung nur das Einlaßventil und ein Signal auf der vom zweiten Ausgang kommenden Ansteuer¬ leitung beide Ventile betätigt.It is e.g. known from DE-OS 1655 318 to connect the inlet and outlet valve of an ABS to ground on one side in parallel and to connect the other side of the inlet valve to a first output of a control unit and the outlet valve to a second output of the control unit. A diode is connected between the two control lines in such a way that a signal on the control line coming from the first output actuates only the inlet valve and a signal on the control line coming from the second output actuates both valves.
Vorteile der ErfindungAdvantages of the invention
Im Grunde genommen sind bei der Lösung gemäß dem Stand der Technik drei Leitungsverbindungen notwendig. Bei der Erfindung sind demgegenüber bei zwei Ventilen nur noch zwei Leitungen notwendig, was den Vorteil von weni¬ ger Kontakten, geringere Zahl von Kabelbaumleitungen und kleinere Stecker mit geringerer Kontaktanzahl hat.Basically, three line connections are necessary in the solution according to the prior art. In contrast, in the case of the invention, only two lines are required for two valves, which has the advantage of fewer contacts, a smaller number of wiring harness lines and smaller plugs with a smaller number of contacts.
FigurenbeschreibungFigure description
Anhand der Fig. 1 und 2 der Zeichnung werden zwei Ausführungsbeispiele der Erfindung mit zwei Ventilen erläutert.1 and 2 of the drawing, two exemplary embodiments of the invention with two valves are explained.
Fig. 3 zeigt ein Ausführungsbeispiel mit drei Ventilen und drei Ansteuer¬ leitungen.3 shows an exemplary embodiment with three valves and three control lines.
In Fig. 1 ist mit 1 ein Einlaßventil (2/2-Magnetventil) und mit 2 ein Aus¬ laßventil (3/2-Magnetventil) eines ABS bezeichnet. Mit dem Auslaßventil 2 liegt eine Diode 3 in Reihe. Wird an den Ansteuerklemmen 4a und 4b die gleiche Spannung, also z.B. die Spannung 0 angelegt, so bleiben die Ventile in ihrer Ausgangsstellung und es ist Druckaufbau möglich. Wird an die Klem¬ me 4a der positive Pol der Gleichspannungsquelle gelegt und an Klemme 4b der negative Pol, dann kann wegen der Sperrwirkung der Diode 3 nur das Ven¬ til 1 ansprechen. Der vorhandene Druck wird dann gehalten. Werden die Pole der Gleichspannungsquelle dagegen vertauscht, dann entfällt die Sperrwir¬ kung der Diode 3 und beide Ventile sprechen an. Der Bremsdruck wird abge¬ baut.In Fig. 1, 1 denotes an inlet valve (2/2 solenoid valve) and 2 denotes an outlet valve (3/2 solenoid valve) of an ABS. With the outlet valve 2 is a diode 3 in series. If the same voltage, for example voltage 0, is applied to the control terminals 4a and 4b, the valves remain in their starting position and pressure build-up is possible. If the positive pole of the DC voltage source is connected to terminal 4a and the negative pole to terminal 4b, only valve 1 can respond due to the blocking action of diode 3. The existing pressure is then maintained. If, on the other hand, the poles of the DC voltage source are interchanged, the blocking effect of the diode 3 is eliminated and both valves respond. The brake pressure is reduced.
Fig. 2 unterscheidet sich von Fig. 1 dadurch, daß das Auslaßventil 12 der¬ art ausgebildet ist, daß es in seiner Schaltstellung Druckabbau die Halte¬ funktion des Einlaßventils 11 nicht benötigt und dadurch, daß auch mit dem Einlaßventil 11 eine gegenüber der Diode 13 umgekehrt gepolte Diode 15 in Reihe liegt. Wird die positive Polung der Gleichspannungsquelle an die Klemme 14a gelegt und der negative an Klemme 14b, so wird nur das Ventil 11 geschaltet. Bei umgekehrter Polung wird wegen der nun vorhandenen Sperrwir¬ kung der Diode 15 nur das Auslaßventil 12 betätigt.Fig. 2 differs from Fig. 1 in that the outlet valve 12 is designed such that it does not require the holding function of the inlet valve 11 in its pressure reduction position and in that the inlet valve 11 also has a function opposite the diode 13 reverse polarity diode 15 is in series. If the positive polarity of the DC voltage source is applied to terminal 14a and the negative one to terminal 14b, only valve 11 is switched. If the polarity is reversed, only the outlet valve 12 is actuated because of the blocking effect of the diode 15 now present.
In Fig. 3 sind zwei Einlaßventile 31 und 32 und ein Auslaßventil 33 paral¬ lel an eine Leitung 1' angeschaltet die andere Klemme der Einlaßventile 31 und 32 sind mit Ansteuerleitungen 2' und 31 verbunden. Die zweite Klemme des Auslaßventils 33 ist über Dioden 34 mit den Ansteuerleitungen 2' und 3' verbunden. Dieses Stellglied könnte bei einer Luftfederung eines Kraftfahr¬ zeuges Anwendung finden, wobei das Ventil in seiner Ausgangslage mit einer Druckquelle verbunden ist und bei Ansteuerung an eine Drucksenke angeschal¬ tet wird. Der andere Ausgang des Ansteuerventils ist über die beiden in Äusgangslage geschlossenen Einlaßventile mit der Luftfederung der beiden Wagenseiten verbunden.In Fig. 3, two intake valves 31 and 32 and an exhaust valve 33 are paral¬ lel 'turned the other terminal of the intake valves 31 and 32 are connected to drive lines 2' to a line 1 1 and 3, respectively. The second terminal of the outlet valve 33 is connected to the control lines 2 'and 3' via diodes 34. This actuator could be used in an air suspension of a motor vehicle, the valve in its starting position being connected to a pressure source and being activated when actuated to a pressure sink. The other outlet of the control valve is connected to the air suspension of the two sides of the car via the two inlet valves which are closed in the initial position.
Die Tabelle der Fig. 3 zeigt die Wirkungsweise der Schaltung bei verschie¬ denen Ansteuerungen mit + oder - Signalen auf den einzelnen Ansteuerleitun¬ gen. Rechts ist aufgelistet, welche Ventile ansprechen. Bei den letzten drei Zeilen wird Druck abgebaut, bei den drei Zeilen davor Druck aufgebaut. The table in FIG. 3 shows the mode of operation of the circuit in the case of various controls with + or - signals on the individual control lines. On the right is listed which valves respond. Pressure is released in the last three lines, pressure is built up in the three lines before.
