Description

Elektromagnetische Stellvorrichtung Electromagnetic actuator
Die Erfindung betrifft eine elektromagnetische Stellvorrichtung, beispielsweise für automatisierte Schaltgetriebe in Kraftfahrzeugen mit einem Elektromagneten und einem beweglichen Anker.The invention relates to an electromagnetic actuator, for example, for automated manual transmission in motor vehicles with an electromagnet and a movable armature.
In automatisierten Schaltgetrieben werden Aktuatoren mit verschiedenen Betätigungsprinzipien verwendet, um Schalt- und Wählpositionen zu erreichen. Eine Vorrichtung zur Betätigung eines Kraftfahrzeugschaltgetriebes, das eine H-Schaltung aufweist, ist beispielsweise aus der DE 199 44 601 A1 bekannt und umfasst eine Antriebseinrichtung, die in Antriebsverbindung mit einer die Schaltbewegung ausführenden Clbertragungseinrichtung verbunden ist, wobei eine Schaltauslöseeinheit zum Betätigen der Antriebseinrichtung und ein Schaltcomputer, der mit der Antriebseinheit und der Schaltauslöseeinheit verbunden ist, vorgesehen sind. Die Antriebseinrichtung umfasst zwei Kolben- Zylinder-Einheiten, die mit einem Druckfluid, insbesondere Druckluft, beaufschlagbar und, durch den Schaltcomputer gesteuert, in drei Bewegungsstellungen einstellbar sind.In automated manual transmissions actuators are used with different operating principles to achieve switching and selection positions. A device for actuating a motor vehicle shift transmission, which has an H-circuit, is known for example from DE 199 44 601 A1 and comprises a drive device which is connected in drive connection with a switching movement exporting Clbertragungseinrichtung, wherein a switching trip unit for actuating the drive means and a Switching computer, which is connected to the drive unit and the switching trip unit, are provided. The drive device comprises two piston-cylinder units, which can be acted upon with a pressurized fluid, in particular compressed air, and, controlled by the switching computer, can be set in three movement positions.
Eine weitere Stellanordnung für ein automatisiertes Getriebe ist in der DE 199 45 805 A1 beschrieben, bei der die Wähl- und Schaltbetätigung des Getriebes mittels jeweils eines Elektromotors erfolgt, die Stellorgane zur Auswahl einer bestimmten Wählposition sowie zum Ein- und Auslegen des gewünschten Ganges aufgrund von Befehlen eines Steuerungscomputers betätigen. Von besonderer Bedeutung bei derartigen Stellanordnungen ist, dass die genutzten Aktuatoren die gewünschte Wähl- bzw. Schaltposition exakt einnehmen und bis zum nächsten Schalt- oder Wählbefehl auch sicher beibehalten.A further actuating arrangement for an automated transmission is described in DE 199 45 805 A1, in which the selection and switching operation of the transmission is effected by means of an electric motor, the actuators for selecting a specific selection position and for engaging and disengaging the desired gear due to Press commands on a control computer. Of particular importance in such arrangements is that the actuators used to take the desired selection or switching position exactly and safely maintained until the next switching or selection command.
Aus der DE 201 00 950 U1 ist schließlich eine elektromagnetische Stellvorrichtung der eingangs erwähnten Art bekannt, deren beweglicher Anker bei Erregung einer Magnetspule angezogen wird und ein hydraulisches oder pneumatisches Steuerventil öffnet und bei Unterbrechung der Stromzufuhr zur Magnetspule durch Federdruck in die Schließstellung des Ventils bewegt wird. Diese bekannte elektromagnetische Stellvorrichtung ist daher als Aktuator zur Betätigung einer Vorrichtung in einem Getriebe, das drei definierte Stellungen aufweisen soll, beispielsweise eine Stellung zum Einlegen eines ersten Ganges, eine Neutralstellung und eine Stellung zum Einlegen eines zweiten Ganges, nicht geeignet.From DE 201 00 950 U1 finally an electromagnetic actuator of the type mentioned above is known, the movable armature is attracted to energization of a solenoid and a hydraulic or opens the pneumatic control valve and is moved by interrupting the power supply to the solenoid coil by spring pressure in the closed position of the valve. This known electromagnetic actuating device is therefore not suitable as an actuator for actuating a device in a transmission which is to have three defined positions, for example a position for engaging a first gear, a neutral position and a position for engaging a second gear.
Der Erfindung liegt die Aufgabe zugrunde, eine elektromagnetische Stellvorrichtung mit drei exakt definierten Schaltstellungen zu schaffen.The invention has for its object to provide an electromagnetic actuator with three well-defined switching positions.
Gemäß den Merkmalen des Hauptanspruchs betrifft die Erfindung daher eine elektromagnetische Stellvorrichtung, beispielsweise für automatisierte Schaltgetriebe in Kraftfahrzeugen, mit einem Elektromagneten und einem beweglichen Anker. Zur Lösung der gestellten Aufgabe ist vorgesehen, dass der Elektromagnet als doppelspuliger Umkehrhubelektromagnet ausgebildet und der Anker durch Erregung jeweils einer Spule in entgegengesetzte Extremstellungen bewegbar ist, am Anker oder einem damit verbundenen Fortsatz ein eine Mittelstellung zwischen den beiden Extremstellungen definierendes Rastelement angeordnet ist und ein steuerbares Verriegelungselement mit dem Rastelement in der Mittelstellung verriegelbar ist.According to the features of the main claim, the invention therefore relates to an electromagnetic actuator, for example for automated manual transmissions in motor vehicles, with an electromagnet and a movable armature. To achieve the object, it is provided that the electromagnet is designed as doppelspuliger Umkehrhubelektromagnet and the armature by excitation of each coil in opposite extreme positions is movable at anchor or an associated extension a middle position between the two extreme positions defining latching element is arranged and a controllable Locking element with the locking element in the middle position can be locked.
Während bei dieser ersten Ausführungsform die Extremstellungen durch entsprechende Erregung jeweils einer Spule erreicht werden und der Anker in diesen Extremstellungen durch Dauererregung der jeweiligen Spule gehalten wird, ist die Mittelstellung mechanisch durch das Rastelement und das darin eingreifende Verriegelungselement eindeutig und formschlüssig definiert, wobei sich diese Mittelstellung zunächst dadurch ansteuern lässt, dass beide Spulen gleichzeitig und gleich stark erregt werden, so dass der Anker die Mittelstellung einnimmt, woraufhin das Verriegelungselement angesteuert und mit dem Rastelement verriegelt wird. Ebenso ist es möglich, den Anker durch Federkraft in die Mittelstellung nach Unterbrechung der Erregung der jeweiligen Spule in die Mittelstellung zu bewegen und dann die Verriegelung in dieser Mittelstellung, beispielsweise auch federbelastet, vorzunehmen.While in this first embodiment, the extreme positions are achieved by appropriate excitation of each coil and the armature is held in these extreme positions by continuous excitation of the respective coil, the center position is defined by the locking element and engaging therein locking element clearly and positively, with this center position Initially, it can be triggered by the fact that both coils are energized simultaneously and equally, so that the armature assumes the middle position, whereupon the locking element is activated and locked with the latching element. Similarly, it is possible to use the anchor by spring force to move the center position after interruption of the excitation of the respective coil in the center position and then perform the locking in this middle position, for example, spring-loaded.
Gemäß einer Weiterbildung der Erfindung kann das Rastelement auch die beiden Extremstellungen definieren und das Verriegelungselement auch in den Extremstellungen mit dem Rastelement verriegelbar sein. In diesem Fall kann die Erregung der jeweiligen Spule nach Erreichen der jeweiligen Extremstellung und Verriegelung ausgeschaltet werden.According to one embodiment of the invention, the locking element can also define the two extreme positions and the locking element can be locked in the extreme positions with the locking element. In this case, the excitation of the respective coil after reaching the respective extreme position and locking can be turned off.
Das Rastelement kann in einfachster Weise aus im Anker angeordneten Rastausnehmungen bestehen, wobei ein senkrecht zur Bewegungsrichtung des Ankers beweglicher Stößel das Verriegelungselement bildet.The latching element can consist in the simplest way of anchoring recesses arranged in the armature, wherein a perpendicular to the direction of movement of the armature movable plunger forms the locking element.
Gemäß einer anderen Ausführungsform kann das Rastelement aus in dem mit dem Anker verbundenen Fortsatz angeordneten Rastausnehmungen bestehen, und ein senkrecht zur Bewegungsrichtung des Fortsatzes beweglicher Stößel bildet wiederum das Verriegelungselement.According to another embodiment, the latching element may consist of latching recesses arranged in the extension connected to the armature, and a plunger which is movable perpendicular to the direction of movement of the extension in turn forms the latching element.
Wenn sich eine Betätigungsvorrichtung für den senkrecht zur Bewegungsrichtung des Ankers beweglichen Stößel aus Platzgründen nicht in Bewegungsrichtung des Stößels anordnen lässt, kann diese Betätigungsvorrichtung für den Stößel auch parallel zur Bewegungsrichtung des Ankers am Elektromagneten angeordnet sein. Sie wirkt dann über eine Umlenkmechanik auf den Stößel.If an actuator for the movable perpendicular to the direction of movement of the armature plunger can not be arranged in the direction of movement of the plunger for reasons of space, this actuator for the plunger can also be arranged parallel to the direction of movement of the armature on the electromagnet. It then acts on the ram via a deflection mechanism.
Die Erfindung wird nachstehend anhand dreier schematisch dargestellter Ausführungsbeispiele näher erläutert. In der Zeichnung zeigtThe invention is explained below with reference to three schematically illustrated embodiments. In the drawing shows
Fig. 1 eine erste Ausführungsform der erfindungsgemäßen elektromagnetischen Stellvorrichtung schematisch im Schnitt, Fig. 2 eine Abwandlung der Ausführungsform gemäß Fig. 1 , und Fig. 3 eine weitere Ausführungsform der elektromagnetischen Stellvorrichtung schematisch im Schnitt.1 shows a first embodiment of the electromagnetic actuating device according to the invention schematically in section, Fig. 2 shows a modification of the embodiment of FIG. 1, and Fig. 3 shows another embodiment of the electromagnetic actuator schematically in section.
Die elektromagnetischen Stellvorrichtungen gemäß den Figuren 1 bis 3 sind beispielhaft für automatisierte Schaltgetriebe in einem Kraftfahrzeug bestimmt. Die Stellvorrichtung gemäß Fig. 1 umfasst einen Elektromagneten 1 und einen linear beweglichen Anker 2, wobei der Elektromagnet 1 als dop- pelspuliger Umkehrhubelektromagnet ausgebildet und der Anker 2 durch Erregung jeweils einer der beiden Magnetspulen 3, 3' in axial entgegengesetzte Extremstellungen bewegbar ist. Der Anker 2 kann in diesen Extremstellungen durch eine Dauererregung der jeweiligen Spule 3, 3' gehalten werden, jedoch sind beim dargestellten Ausführungsbeispiel am Anker 2 Rastausnehmun- gen 10, 10' angeordnet, welche die beiden Extremstellungen definieren und in die ein Stößel 5 als Verriegelungselement in den jeweiligen Extremstellungen einrasten kann.The electromagnetic actuating devices according to FIGS. 1 to 3 are intended by way of example for automated manual transmissions in a motor vehicle. The actuating device according to FIG. 1 comprises an electromagnet 1 and a linearly movable armature 2, wherein the electromagnet 1 is designed as a double-coil reversing lifting electromagnet and the armature 2 can be moved into axially opposite extreme positions by excitation of one of the two magnet coils 3, 3 ' . The armature 2 can be held in these extreme positions by a continuous excitation of the respective coil 3, 3 ' , however, in the illustrated embodiment at the anchor 2 Rastausnehmun- gene 10, 10 ' are arranged, which define the two extreme positions and in which a plunger 5 as a locking element can engage in the respective extreme positions.
Eine elektromagnetische Betätigungsvorrichtung für diesen Stößel 5 besteht aus einem mit dem Stößel 5 verbundenen Anker 8, der in einer Spule 7 gegen die Kraft einer Feder 9 quer zur Bewegungsrichtung des Ankers 2 beweglich ist.An electromagnetic actuator for this plunger 5 consists of a connected to the plunger 5 anchor 8, which is movable in a coil 7 against the force of a spring 9 transversely to the direction of movement of the armature 2.
Eine Mittelstellung des Ankers 2 wird durch eine mittlere Rastausneh- mung 4 im Anker 2 definiert, in die der Stößel 5 gemäß Fig. 1 eingreift und so den Anker 2 und einen damit verbundenen Betätigungsstößel 6 in der Mittelstellung verriegelt.A middle position of the armature 2 is defined by a central latching recess 4 in the armature 2, in which the plunger 5 engages according to FIG. 1 and thus locks the armature 2 and an associated actuating plunger 6 in the middle position.
Die erfindungsgemäße elektromagnetische Stellvorrichtung weist somit drei definierte, formschlüssig verriegelbare Stellungen auf, wobei die durch die Rastausnehmungen 10, 10' definierten Extremstellungen beispielsweise dem Einrücken eines ersten oder zweiten Ganges in einem Getriebe entsprechen, während die durch die Rastausnehmung 4 definierte Mittelstellung der Neutralstellung zwischen dem ersten und zweiten Gang entspricht.The electromagnetic actuating device according to the invention thus has three defined, positively lockable positions, wherein the extreme positions defined by the latching recesses 10, 10 ' correspond, for example, to the engagement of a first or second gear in a transmission, while the center position defined by the latching recess 4 corresponds to the neutral position between the first and second gear.
Mittels des Betätigungsstößels 6 lässt sich beispielsweise ein Hydraulikoder Pneumatikwegeventil ansteuern, über das Kolben-Zylinder-Einheiten für den Gangwechsel und für die Neutralstellung angesteuert werden. Bei geeigneter Dimensionierung ist es jedoch auch möglich, den Gangwechsel und die Neutralstellung direkt durch die erfindungsgemäße elektromagnetische Stellvorrichtung zu bewirken.By means of the actuating tappet 6, for example, a hydraulic or pneumatic directional control valve can be controlled via which the piston-cylinder units are controlled for the gear change and for the neutral position. With suitable dimensioning, however, it is also possible to effect the gear change and the neutral position directly by the electromagnetic actuator according to the invention.
Reicht der Platz im Getriebe nicht aus, die aus der Spule 9, dem Anker 8 und der Feder 9 bestehende Betätigungsvorrichtung für den Stößel 5 senkrecht zur Bewegungsrichtung des Ankers 2 am Elektromagneten 1 anzuordnen, so ist es gemäß Fig. 2 möglich, den Stößel 5 mit einer Umlenkmechanik 1 1 , beispielsweise einem Winkelhebel zu verbinden, so dass sich die Spule 7, der Anker 8 mit der Feder 9 und einem mit dem Anker 8 und der Umlenkmechanik 1 1 verbundenen Stößel 12 parallel zur Bewegungsrichtung des Ankers 2 anordnen lässt.If there is not enough space in the gearbox to arrange the actuating device for the plunger 5 perpendicular to the direction of movement of the armature 2 on the electromagnet 1 consisting of the coil 9, the armature 8 and the spring 9, it is possible for the plunger 5 to be shown in FIG with a deflection mechanism 1 1, for example, to connect an angle lever, so that the coil 7, the armature 8 with the spring 9 and a connected to the armature 8 and the deflection mechanism 1 1 plunger 12 can be arranged parallel to the direction of movement of the armature 2.
Die Ausführungsform gemäß Fig. 3 unterscheidet sich von denen gemäß den Figuren 1 und 2 dadurch, dass ein Fortsatz 13 am Betätigungsstößel 6 außerhalb des Elektromagneten 1 angeordnet ist, der mit den Rastausneh- mungen 4 und 10, 10' versehen ist, wobei die drei möglichen Stellungen des Ankers 14 wiederum durch die Rastausnehmungen 4, 10, 10' definiert sind, in die der Stößel 5 der aus der Spule 7, dem Anker 8 und der Feder 9 bestehenden Betätigungsvorrichtung eingreift.The embodiment according to FIG. 3 differs from those according to FIGS. 1 and 2 in that an extension 13 is arranged on the actuation tappet 6 outside the electromagnet 1, which is provided with the detent recesses 4 and 10, 10 ' , wherein the three possible positions of the armature 14 are in turn defined by the recesses 4, 10, 10 ' , in which engages the plunger 5 of the coil 7, the armature 8 and the spring 9 existing actuator.
Bei allen dargestellten Ausführungsbeispielen wird der Stößel 5 durch die Feder 9 in die Verriegelungsstellung bewegt, jedoch ist es selbstverständlich auch möglich, diese Anordnung umzukehren oder statt nur einer Spule 7 einen doppelspuligen Umkehrhubelektromagneten vorzusehen, so dass auf die Feder 9 verzichtet werden kann.In all the illustrated embodiments, the plunger 5 is moved by the spring 9 in the locking position, but it is of course also possible to reverse this arrangement or instead of only one coil. 7 to provide a doppelspuligen Umkehrhubelektromagneten so that it can be dispensed with the spring 9.
Allen Ausführungsformen ist gemeinsam, dass die elektromagnetische Stellvorrichtung drei definierte Schaltstellungen aufweist, wovon zumindest die Mittelstellung durch eine Verriegelung formschlüssig festgelegt wird. All embodiments have in common that the electromagnetic actuator has three defined switching positions, of which at least the center position is fixed by a positive locking.
