Die Erfindung wird zweckmäßigerweise gemäß den Merkmalen nach Anspruch 6 in Leuchtweiteregelungsanlagen angewendet.the features of claim 2, the metal plate is unnecessary when the annular disc depending on the overpressure or Underpressure of the pressure source either inside the pressure chamber or outside it engages on the piston rod. The invention is expediently applied in accordance with the features of claim 6 in headlight range control systems.
Zeichnungdrawing
Ein Ausführungsbeispiel der Erfindung ist in der einzigen Figur dargestellt und in nachfolgender Beschreibung näher erläutert. Die einzige Figur zeigt das Ausführungsbeispiel mit Blockschaltbild und axial geschnittenem, hydraulischem Motor im vergrößerten Maßstab.An embodiment of the invention is shown in the single figure and in more detail in the following description explained. The single figure shows the embodiment with a block diagram and an axially cut, hydraulic Motor on an enlarged scale.
Ein hydraulischer Motor 10 ist im wesentlichen bezüglich der Achse 9 rotationssymmetrisch und über eine Leitung 11 mittelbar an einem Saugrohr 12 eines nicht dargestellten Verbrennungsmotor angeschlossen. In der Leitung 11 sind ein Rückschlagventil 13 und ein Druckregler 15 zwischengeschaltet. Ein Vorratsbehälter 14 der Leitung 11 wird vom Unterdruck im Saugrohr 12 evakuiert, so daß der Druckregler 15 mit einem vorbestimmten Unterdruck beaufschlagbar ist.A hydraulic motor 10 is essentially rotationally symmetrical with respect to the axis 9 and via a line 11 indirectly connected to an intake manifold 12 of an internal combustion engine, not shown. In the line 11 are a Check valve 13 and a pressure regulator 15 are interposed. A reservoir 14 of the line 11 is from Negative pressure in the suction pipe 12 is evacuated, so that the pressure regulator 15 can be acted upon with a predetermined negative pressure is.
Der Motor 10 hat eine erste und zweite Gehäuseschale 16, 17, zwischen denen eine Membran 18 eingespannt ist, die die Form einer Lochscheibe hat. Diese hat einen starren Abschnitt 19, dessen Innenbereich ein Ringwulst 20 verstärkt. Eine Kolbenstange 21 hat eine Hülse 22, deren einer Endabschnitt als Kugelpfanne ausgebildet ist und deren anderer Endabschnitt in einen Anschlag 23 übergeht. An diesem und an der Gehäuseschale 17 stützt sich eine Schraubenfeder 2k ab, die das Bestreben hat, die Kolbenstange 21 in Pfeilrichtung 25 zu drücken. Die Kolbenstange 21 mit dem Anschlag 23 bestehen aus elastischem Kunststoff.The motor 10 has a first and second housing shell 16, 17, between which a membrane 18 is clamped, which has the shape of a perforated disk. This has a rigid section 19, the inner area of which is reinforced by an annular bead 20. A piston rod 21 has a sleeve 22, one end section of which is designed as a ball socket and the other end section of which merges into a stop 23. A helical spring 2k is supported on this and on the housing shell 17 and tends to push the piston rod 21 in the direction of arrow 25. The piston rod 21 with the stop 23 are made of elastic plastic.

Die Gehäuseschale 17, die Membrane 18 und der Anschlag der Kolbenstange 21 bilden eine Druckkammer 26, die eine Tülle 27 mit der Leitung 11 verbindet; in der Druckkammer 26 herrscht mithin ein Unterdruck, der durch den Druckregler 15 in einem bestimmten Bereich verstellbar ist.The housing shell 17, the membrane 18 and the stop the piston rod 21 form a pressure chamber 26 which connects a grommet 27 with the line 11; in the pressure chamber 26 there is therefore a negative pressure which can be adjusted by the pressure regulator 15 in a certain range.
Eine aus elastischem Kunststoff hergestellte Ringscheibe 28 ist in axialer Richtung entsprechend dem Ringwulst 20 der Membrane 18 abgekröpft und hat einen äußeren Bereich und einen in axialer Richtung federnden Lochbereich 30, der in eine äußere Ringnut 31 der Hülse 22 der Kolbenstange 21 nach Art einer Rastanordnung einrastet.An annular disk 28 made of elastic plastic is in the axial direction corresponding to the annular bead 20 of the diaphragm 18 cranked and has an outer area and an axially resilient hole area 30, in an outer annular groove 31 of the sleeve 22 of the piston rod 21 engages in the manner of a latching arrangement.
Die Membran 18 wird mittels der Rastanordnung an der Kolbenstange 21 dadurch befestigt, daß man die Ringscheibe zuerst über den federnden Endabschnitt der Kolbenstange schiebt, dabei weitet sich der Lochbereich 30 radial auf; die Ringscheibe 28 wird dann soweit geschoben, bis deren Lochbereich 30 in die Ringnut 31 einrastet und sich an deren Schulter 32 abstützt, so daß der äußere Bereich 29 den Wulst 20 und einen Teil des starren Abschnittes 19 der Membran 18 an den Anschlag 23 der Kolbenstange 21 drückt.The membrane 18 is fastened to the piston rod 21 by means of the latching arrangement in that the annular disk is first pushed over the resilient end section of the piston rod, the hole area 30 expanding radially; the annular disk 28 is then pushed until its hole area 30 engages in the annular groove 31 and is supported on its shoulder 32 so that the outer area 29 rests the bead 20 and part of the rigid section 19 of the membrane 18 against the stop 23 of the piston rod 21 presses.
Der hydraulische Motor wird vor allem als Stellglied für das Einstellen der Leuchtweite vom nicht gezeichneten Fahrzeugscheinwerfern verwendet. Hierbei ist der Zylinder 16, ortsfest an einem Scheinwerferabschnitt befestigt und die Kolbenstange 21 ist unter vorzugsweise Zwischenschaltung eines Stößels mit dem Scheinwerferreflektor gekuppelt.The hydraulic motor is mainly used as an actuator for adjusting the headlight range of the vehicle headlights (not shown) used. Here, the cylinder 16 is fixedly attached to a headlight section and the Piston rod 21 is coupled to the headlight reflector, preferably with the interposition of a plunger.
