Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Türbetätigungseinrichtung nach der Gattung des Hauptanspruchs. Eine derartige Türbetätigungseinrichtung ist bekannt - Bosch-Druckschrift VDT-AKB 130/2, Blatt 1 (2.67).The invention relates to a door operating device according to the preamble of the main claim. Such a door operating device is known - Bosch publication VDT-AKB 130/2, sheet 1 (2.67).

Bei solchen Türbetätigungseinrichtungen tritt das Problem auf, daß bei der Betätigung der Notsteuerung der Arbeitszylinder auch auf der Schließseite entlüftet wird. Beim Zurückschalten des Nothahns erhält dann die Schließseite Druck, und die Tür schließt schlagartig, weil auf der Gegenseite kein Druck ist. Dadurch sind aber schon schwere Unfälle entstanden.In such door actuators, the problem arises that when the emergency control is actuated, the working cylinder is also vented on the closing side. When the emergency valve is switched back, the closing side is given pressure and the door closes suddenly because there is no pressure on the opposite side. This has already resulted in serious accidents.

Er ist auch bereits eine speziell für Eisenbahntüren bestimmte Einrichtung bekannt, bei der vom Zugführer durch Betätigung eines Magnetventils alle Türen gemeinsam geschlossen werden (DE-A-2 807 050). Dort ist eine Notbetätigung angesprochen, mit der es dem Fahrgast ermöglicht wird, durch Entlüften des Systems eine mechanische Verriegelung der Tür zu lösen, um die Tür zu öffnen. Eine Sicherung vor schlagartigem Schließen ist aber nicht vorgesehen.It is also already known to be a facility specially designed for railway doors, in which the train driver closes all doors together by actuating a solenoid valve (DE-A-2 807 050). An emergency actuation is addressed there, with which the passenger is able to release a mechanical lock of the door by venting the system in order to open the door. Protection against sudden closing is not provided.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Türbetätigungseinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die normale Betätigung vom Fahrzeugführer in Schließ- und Öffnungsrichtung kombiniert ist mit einer Notbetätigung, welche die Schließleitung drucklos macht. Durch die Notbetätigung kann der Fahrgast die Tür von Hand zwar ebenfalls öffnen und schließen, aber der Nothahn ist nicht in seine Ausgangsstellung zurückbewegbar, weil er verrastet ist, bis der Fahrzeugführer das Türventil in Tür-Öffnungsstellung bringt. Dann wird der Druck im Arbeitszylinder zuerst auf beiden Seiten aufgebaut, und die Verrastung des Nothahnes wird erst gelöst, wenn ein gewisser Druck erreicht ist, damit die Tür nicht schlagartig schließt. Dadurch ist erreicht, daß ausgehend vor jeder Stellung des Arbeitszylinders und in jeder Richtung eine Endlagendämpfung des Arbeitszylinders wirksam ist.The door actuation device according to the invention with the characterizing features of the main claim has the advantage that the normal actuation by the driver in the closing and opening direction is combined with an emergency actuation, which depressurizes the closing line. The emergency operation also allows the passenger to open and close the door by hand, but the emergency valve cannot be moved back to its original position because it is locked until the driver puts the door valve in the open position. Then the pressure in the working cylinder is first built up on both sides, and the locking of the emergency valve is only released when a certain pressure is reached so that the door does not close abruptly. It is thereby achieved that, starting from each position of the working cylinder and in every direction, end position damping of the working cylinder is effective.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Eine Tür 1 ist über eine Kolbenstange 2 mit einem doppelwirkenden Kolben 3 eines Zweikammer-Arbeitszylinders 4 verbunden. Die zwei Kammern 5 und 6 des Arbeitszylinders 4 sind über Anschlüsse an je eine Luftleitung 7 bzw. 8 angeschlossen, von denen die von der Öffnungsseite x des Arbeitszylinders 4 ausgehende Leitung 7 unmittelbar zu einem Türventil 9 führt, das als 3/2-Wege-Magnetventil ausgebildet ist und an das ein Vorratsbehälter 20 als Druckquelle angeschlossen ist.A door 1 is connected via a piston rod 2 to a double-acting piston 3 of a two-chamber working cylinder 4. The two chambers 5 and 6 of the working cylinder 4 are connected via connections to an air line 7 or 8, of which the line 7 starting from the opening side x of the working cylinder 4 leads directly to a door valve 9, which as a 3/2-way Solenoid valve is formed and to which a reservoir 20 is connected as a pressure source.

Die andere, von der Schließseite y des Arbeitszylinders 4 ausgehende Leitung 8 führt zu einer Notsteuerung 10 und dort zu einem als 3/2-WegeVentil 11 ausgebildeten Mehrwegeventil, das von Hand betätigbar ist. Die Betätigung des Ventils 11 kann entweder durch einen Knebel oder einen Drehknopf erfolgen, wobei die Betätigung vorzugsweise so arbeiten soll, daß sie nur in einer Richtung Kraft übertragen kann.The other line 8 starting from the closing side y of the working cylinder 4 leads to an emergency control 10 and there to a multi-way valve designed as a 3/2-way valve 11 which can be operated by hand. The valve 11 can be actuated either by a toggle or a rotary knob, the actuation preferably being to operate in such a way that it can only transmit force in one direction.

Als 3/2-Wege-Ventil 11 hat sich ein Drehschieberventil bewährt, das mit einer Drehfeder versehen ist. Beim Betätigen wird die Drehfeder gespannt, und am Ende der Verdrehung wird eine Radial-Verriegelung 12 (Figuren 2 und 3) erreicht, und diese Verriegelung ist über ein Arbeitsglied 13 pneumatisch lösbar, wonach der pneumatische Druck auch die Rückführung des 3/2-WegeVentils 11 in seine Ausgangsstellung unterstützt. Ein solches 3/2-Wege-Ventil ist in der DE-OS 24 39 589 beschrieben.A rotary slide valve, which is provided with a torsion spring, has proven itself as a 3/2-way valve 11. When actuated, the torsion spring is tensioned, and at the end of the rotation, a radial lock 12 (Figures 2 and 3) is reached, and this lock can be released pneumatically via a working member 13, after which the pneumatic pressure also returns the 3/2-way valve 11 supported in its starting position. Such a 3/2-way valve is described in DE-OS 24 39 589.

Dem Arbeitsglied 13 ist eine Drossel 14 vorgeschaltet. Die Drossel 14 kann auch durch eine Feder 14' am Arbeitsglied 13 ersetzt sein. Drossel 14 oder Feder 14' bilden eine druck- oder zeitabhängige Verzögerungseinrichtung. Arbeitsglied 13 und Drossel 14 liegen in einer Zweigleitung 15, die Verbindung mit der Luftleitung 7 hat, die einerseits mit der Öffnungsseite x des Arbeitszylinders 4 und mit dem Türventil 9 verbunden ist und die andererseits über eine Leitung 16 an einen dritten Anschluß des Ventils 11 angeschlossen ist.A throttle 14 is connected upstream of the working member 13. The throttle 14 can also be replaced by a spring 14 'on the working member 13. Throttle 14 or spring 14 'form a pressure or time-dependent delay device. Working member 13 and throttle 14 are in a branch line 15, which has connection to the air line 7, which is connected on the one hand to the opening side x of the working cylinder 4 and with the door valve 9 and on the other hand connected via a line 16 to a third connection of the valve 11 is.

WirkungsweiseMode of action

Die Figuren 1 bis 4 zeigen die Türbetätigungseinrichtung in verschiedenen Stellungen. Es sind deshalb für gleiche Teile die gleichen Bezugszahlen verwendet.Figures 1 to 4 show the door operating device in different positions. The same reference numbers are therefore used for the same parts.

In der Figur 1 hat das Türventil 9 eine derartige Stellung, daß die Tür 1 geschlossen ist. Es wird nun angenommen, daß der das Türventil 9 verstellende Magnet keinen Strom erhält, dann kann das Türventil 9 nicht umschalten und die Fahrgäste können nicht aussteigen.In Figure 1, the door valve 9 has such a position that the door 1 is closed. It is now assumed that the magnet adjusting the door valve 9 receives no current, then can do not switch the door valve 9 and the passengers cannot get out.

Die Figur 2 zeigt den Zustand der Türbetätigungseinrichtung, wenn von irgend jemand die Notsteuerung 10 betätigt wurde. Das von Hand betätigbare 3/2-Ventil 11 nimmt dann seine andere Stellung ein, in der nun auch die Schließseite y des Arbeitszylinders 4 entlüftet wird, und zwar über das 3/2-Ventil 11, die Leitungen 16 und 7 und das Türventil 9. Dadurch kann die Tür 1 mit dem doppelt wirkenden Kolben 3 in dem Arbeitszylinder 4 ohne Widerstand in Offenstellung verschoben werden. Die Fahrgäste können aussteigen.FIG. 2 shows the state of the door operating device when the emergency control 10 has been operated by someone. The manually operated 3/2 valve 11 then assumes its other position, in which the closing side y of the working cylinder 4 is now also vented, specifically via the 3/2 valve 11, the lines 16 and 7 and the door valve 9 As a result, the door 1 with the double-acting piston 3 in the working cylinder 4 can be moved into the open position without resistance. The passengers can get out.

Die Figur 3 zeigt, daß bei verriegeltem 3/2-Ventil 11 die Tür in jeder Stellung zwischen « zu und « offen stehen kann. Das Ventil 11 steht in Kurzschlußstellung. Damit ist die Vorschrift erfüllt, daß eine Betätigung der Notsteuerung keine druckmittelbewirkte Bewegung der Tür nach sich zieht. Die Stromversorgung des Magneten des Türventils 9 ist wieder intakt ; deshalb kann das Türventil 9 in Stellung « Öffnen geschaltet werden. Dadurch werden die beiden Arbeitskammern 5 und 6 des Arbeitszylinders 4 gleichmäßig belüftet. Die Tür 1 bleibt aber stehen wie sie stand.FIG. 3 shows that when the 3/2 valve 11 is locked, the door can be open in any position between “closed and”. The valve 11 is in the short-circuit position. This fulfills the requirement that actuation of the emergency control does not result in pressure-induced movement of the door. The power supply to the magnet of the door valve 9 is intact again; therefore the door valve 9 can be switched to the «open» position. As a result, the two working chambers 5 and 6 of the working cylinder 4 are evenly ventilated. Door 1 remains as it was.

In der Figur 4 ist nun zu sehen, daß sich durch den beispielsweise über die Drossel 14 verzögerten Druckanstieg am Arbeitsglied 13 die Verriegelung gelöst hat und das 3/2-Ventil 11 der Notsteuerung 10 wieder in seine Ausgangsstellung zurückgekehrt ist. Die Schließseite y des Arbeitszylinders 4 wird entlüftet, und die Tür 1 geht in Offenstellung. Es ist also ein wichtiges Merkmal der erfindungsgemäßen Einrichtung, daß die Notsteuerung 10 nur dann in ihre Ausgangsstellung zurückgeht, wenn das Türventil 9 vorher seine Offenstellung eingenommen hatte. Damit ist erreicht, daß ausgehend von jeder Stellung des Arbeitszylinders und in jeder Richtung die Endlagendämpfung im Arbeitszylinder wirksam ist. In der Offenstellung kann eine Betätigung der Notsteuerung kein Schließen der Tür und keine Verriegelung der Notbetätigung bewirken, weil das Arbeitsglied 13 der Verriegelung 12 unter Druck steht (Stellung nach Figur 4). Zum Schließen der Tür 1 muß nun erst wieder das Türventil 9 in die Stellung nach Figur 1 gebracht werden.In FIG. 4 it can now be seen that the locking on the working member 13 has been released by the pressure increase delayed, for example, via the throttle 14, and the 3/2 valve 11 of the emergency control 10 has returned to its starting position. The closing side y of the working cylinder 4 is vented and the door 1 goes into the open position. It is therefore an important feature of the device according to the invention that the emergency control 10 only returns to its starting position if the door valve 9 had previously assumed its open position. This ensures that the end position damping in the working cylinder is effective starting from every position of the working cylinder and in every direction. In the open position, actuation of the emergency control cannot bring about a closing of the door and no locking of the emergency actuation, because the working member 13 of the lock 12 is under pressure (position according to FIG. 4). To close the door 1, the door valve 9 must first be brought into the position shown in FIG. 1.
