Definitions
- Such actuator for reciprocating internal combustion engines is from the WO 2010/097298 A1 known.
- the permanent magnets operatively connected to the solenoid unit are secured to the inner ends of the control needles.
- spring which load the control pins together with permanent magnets in the direction of clamping body and clamp them to set the Aktorstatte in its inner position
- the solenoid unit attracts the permanent magnets and thus the control needles against the force of the springs and thus the terminal body Est has shown that the Aktorstatte when inserted by the ejection ramp are not quickly locked or, for example, caused by vibrations of Hubkolbenbrennkraftmaschine, solve in the locking device and contact the sliding grooves or lying next to the sliding grooves peripheral area unwanted.
- the unwanted loosening of the lock can also occur when the actuator pin passes over edges on the high circle of the displacement cam unit. If the actuator pin slides in the direction of the cam contour of the sliding cam unit, it is reset when the ejection ramp is passed over, ie the sunken actuator pin is pushed back to the level of the high-revving cam unit. In this case, the control needle immediately after pushing up the Aktorstattes again ensure the locking of the locking device, which is only the case when caused by the spring force of the control needle acceleration is high enough to cause the lock fast enough, but not always the case.
- the spring on the actuator pin In order to be able to extend the actuator pin sufficiently fast, even at low temperatures and low viscosity of the engine oil, the spring on the actuator pin must be made sufficiently strong. As a result, the acceleration caused by the spring on the actuator pins, especially in the case of a warm reciprocating internal combustion engine, is high, so that a false lock is enhanced by the control needles.
- the object of the invention is therefore to improve an actuator for reciprocating internal combustion engines so that the disadvantages described above are avoided. It should be ensured that the control needles react quickly enough even in the border areas and track the lock fast enough to clamp the Aktorstatte. This should be done with simple and inexpensive means.
- the object of the invention is achieved in that the defined by spring force per moving mass acceleration of the control needles are matched by their feathers of the acceleration of the actuator pins by the spring force associated therewith substantially.
- the reduction of the mass takes place by decoupling the permanent magnet from the control needle.
- the mass of the control needle unit to be moved by the spring is now considerably lower, so that the acceleration considerably can be increased.
- the spring now only needs the actual control needle without the mass of the permanent magnet in the direction of locking device to accelerate, so that a considerably faster locking takes place, which is all operating conditions.
- a spring plate is fixed, which forms a stop for the permanent magnet, so that this, moved by the solenoid unit, the control pin can release from the lock.
- the spring plate continues to serve as a support for the respective spring of the control needle, which is supported on a component adjacent to the electromagnet unit.
- the spring plate may be caulked with the end of the shaft of the control pin. But it is also possible that the spring plate has a shaft in which an inwardly projecting groove is incorporated, which corresponds to a groove on the shaft of the control needle, so that the spring plate can be advanced with the flange on the end of the shaft and there engages in the groove.
- a steel disc with radial and axial play can be arranged, which is installed between the permanent magnet and a shoulder at the end of the shaft of the control needle.
- 1 denotes a control needle, which has a cylindrical bearing portion 2, a control tip 3 and a shaft 4.
- the shaft 4 has a reduced diameter, which adjoins the storage area 2 by means of a shoulder 5.
- a designated 6 spring plate is attached, which has a flange 7 which is engaged by means of a groove in a groove of the shaft 4 of the control needle 1 and thereby fixed.
- a permanent magnet 8 and a steel plate 9 is arranged on the shaft 4, which only partially fill the axial space of the shaft between disc spring 6 and paragraph 5 and continue to be arranged with radial play on the shaft 4, so that a complete decoupling of the formed as a disc permanent magnet 8 and the steel plate 9 against the control needle 1 is present.
- the control needle 1 with the spring plate 6, the permanent magnet 8 and the steel plate 9 are, as in FIG. 3 shown, part of an actuator designated 10.
- the actuator unit 10 has a sleeve 11 in which actuator pins 12 are displaceably guided with the interposition of sliding sleeves 13.
- the sliding sleeves 13 have conical extensions 14 at their inner ends on, which are in operative connection with trained as balls clamping bodies 15.
- the clamping body 15 are installed in openings of the actuator pins 12 and are dominated by the control tips 3 of the control needles 1.
- the actuator pins 12 are loaded by compression springs 16 in the extension direction, wherein the compression springs 16 are supported on guide elements 17, which are fixed to the sleeve 11.
- the guide elements 17 have bearings in which the storage area 2 of the control needles 1 radially fixed, but is guided axially movable.
- the spring plate 6 of the control needles 1 is connected to a spring 18 in operative connection, which is designed as a compression spring and further supported on a component 19, to which, not shown, the electromagnet unit connects, so that the component 19 is preferably not carried out magnetically.
- the solenoid unit To release the clamping body 15 and thus unlocking the actuator pins 12, the solenoid unit, not shown, is energized so that it attracts the permanent magnets 8 and the steel discs 9 and thus raises the control needles 1 with spring plate 6 against the force of the spring 18.
- the decoupling of the permanent magnets 8 and the steel discs 9 according to the invention also unlocking the control needles 1 has become faster, since the solenoid initially only the permanent magnets 8 and the steel discs 9 must move, then, accelerated, faster and safer move the control needles 1 and the springs 18 can compress.

Eine derartige Aktoreinheit für Hubkolbenbrennkraftmaschinen ist aus der
Um den Aktorstift auch bei tiefen Temperaturen und niedriger Viskosität des Motoröls hinreichend schnell ausfahren zu können, muss die Feder am Aktorstift hinreichend stark ausgeführt sein. Dies führt dazu, dass die durch die Feder am Aktorstifte hervorgerufene Beschleunigung, insbesondere bei warmer Hubkolbenbrennkraftmaschine, hoch ist, so dass eine Fehlarretierung durch die Steuernadeln verstärkt wird.In order to be able to extend the actuator pin sufficiently fast, even at low temperatures and low viscosity of the engine oil, the spring on the actuator pin must be made sufficiently strong. As a result, the acceleration caused by the spring on the actuator pins, especially in the case of a warm reciprocating internal combustion engine, is high, so that a false lock is enhanced by the control needles.
Aufgabe der Erfindung ist es daher, eine Aktoreinheit für Hubkolbenbrennkraftmaschinen so zu verbessern, dass die zuvor beschriebenen Nachteile vermieden werden. Es soll sichergestellt sein, dass die Steuernadeln auch in den Grenzbereichen immer schnell genug reagieren und die Arretierung schnell genug nachführen, um die Aktorstifte zu klemmen. Dies soll mit einfachen und kostengünstigen Mitteln erfolgen.The object of the invention is therefore to improve an actuator for reciprocating internal combustion engines so that the disadvantages described above are avoided. It should be ensured that the control needles react quickly enough even in the border areas and track the lock fast enough to clamp the Aktorstifte. This should be done with simple and inexpensive means.
Die Aufgabe der Erfindung wird dadurch gelöst, dass die durch Federkraft pro bewegter Masse definierte Beschleunigung der Steuernadeln durch ihre Federn der Beschleunigung der Aktorstifte durch die diesen zugeordnete Federkraft im Wesentlichen angeglichen sind.The object of the invention is achieved in that the defined by spring force per moving mass acceleration of the control needles are matched by their feathers of the acceleration of the actuator pins by the spring force associated therewith substantially.
Dadurch wird sichergestellt, dass die Steuernadeln so schnell reagieren können, wie auch die Aktorstifte durch ihre Federn beschleunigt werden, so dass auch bei den zum Stand der Technik beschriebenen Problemen immer hinreichend schnell eine Arretierung der Rasteinrichtungen der Aktorstifte erfolgt. Dies könnte einmal dadurch erfolgen, dass die Federkraft der den Steuernadeln zugeordneten Federn erheblich erhöht wird. Dies ist jedoch nicht ohne Weiteres möglich, da die Spule der Elektromagneteinheit beim Entriegeln immer gegen die Kraft der Federn der Steuernadeln arbeiten muss und somit eine größere Spule mit erhöhter Leistungsaufnahme und Abschaltenergie verwendet werden müsste. Dies führt jedoch zu unerwünscht großen Spulen.This ensures that the control needles can react as quickly as the actuator pins are accelerated by their springs, so that even with the problems described in the prior art always sufficiently fast locking of the locking devices of Aktorstifte takes place. This could be done once by the spring force of the springs associated with the control pins is significantly increased. However, this is not readily possible because the coil of the solenoid unit when unlocking must always work against the force of the springs of the control needles and thus a larger coil with increased power and cut-off energy would have to be used. However, this leads to undesirably large coils.
In weiterer Ausgestaltung der Erfindung wird daher vorgeschlagen, dass die bewegte Masse der Steuernadeln zwecks Angleichung der Beschleunigung entsprechend verringert wird.In a further embodiment of the invention it is therefore proposed that the moving mass of the control needles for the purpose of equalizing the acceleration is reduced accordingly.
Deshalb wird in weiterer Ausgestaltung der Erfindung vorgeschlagen, dass die Verringerung der Masse durch Entkoppeln des Dauermagneten von der Steuernadel erfolgt. Dadurch wird nun die Masse der durch die Feder zu bewegenden Steuernadeleinheit erheblich geringer, so dass die Beschleunigung erheblich erhöht werden kann. Die Feder braucht nun nur noch die eigentliche Steuernadel ohne die Masse des Dauermagneten in Richtung Rasteinrichtung zu beschleunigen, so dass eine erheblich schnellere Arretierung erfolgt, die allen Betriebsbedingungen gerecht wird.Therefore, it is proposed in a further embodiment of the invention that the reduction of the mass takes place by decoupling the permanent magnet from the control needle. As a result, the mass of the control needle unit to be moved by the spring is now considerably lower, so that the acceleration considerably can be increased. The spring now only needs the actual control needle without the mass of the permanent magnet in the direction of locking device to accelerate, so that a considerably faster locking takes place, which is all operating conditions.
In vorteilhafter Weise weisen die Steuernadeln an ihren dem Dauermagneten zugewandten Endbereichen einen Schaft auf, auf dem der Dauermagnet mit radialem und axialem Spiel angeordnet ist.Advantageously, the control needles on their end faces facing the permanent magnet on a shaft on which the permanent magnet is arranged with radial and axial play.
Am Ende des Schaftes ist ein Federteller befestigt, der einen Anschlag für den Dauermagneten bildet, so dass dieser, bewegt durch die Elektromagneteinheit, die Steuernadel aus der Arretierung lösen kann. Der Federteller dient weiterhin als Stütze für die jeweilige Feder der Steuernadel, die sich an einem der Elektromagneteinheit benachbarten Bauteil abstützt.At the end of the shaft, a spring plate is fixed, which forms a stop for the permanent magnet, so that this, moved by the solenoid unit, the control pin can release from the lock. The spring plate continues to serve as a support for the respective spring of the control needle, which is supported on a component adjacent to the electromagnet unit.
Der Federteller kann mit dem Ende des Schaftes der Steuernadel verstemmt sein. Es ist aber auch möglich, dass der Federteller einen Schaft aufweist, in dem eine nach innen vorstehende Rille eingearbeitet ist, die mit einer Nut am Schaft der Steuernadel korrespondiert, so dass der Federteller mit dem Flansch über das Ende des Schaftes vorgeschoben werden kann und dort in der Nut einrastet.The spring plate may be caulked with the end of the shaft of the control pin. But it is also possible that the spring plate has a shaft in which an inwardly projecting groove is incorporated, which corresponds to a groove on the shaft of the control needle, so that the spring plate can be advanced with the flange on the end of the shaft and there engages in the groove.
Zur Verbesserung des Magnetflusses kann zusätzlich zu dem Steuermagneten auf dem Schaft der Steuernadel eine Stahlscheibe mit radialem und axialem Spiel angeordnet sein, die zwischen dem Dauermagneten und einem Absatz am Ende des Schaftes der Steuernadel eingebaut ist.To improve the magnetic flux, in addition to the control magnet on the shaft of the control needle, a steel disc with radial and axial play can be arranged, which is installed between the permanent magnet and a shoulder at the end of the shaft of the control needle.
Es sei ausdrücklich darauf hingewiesen, dass das Prinzip der Entkopplung einer Masse bei bewegten Schaltelementen auch auf andere Schaltventile übertragen werden kann, bei denen durch die gezielte Gesamtmassenänderung eine Erhöhung der Reaktionsfähigkeit erreicht werden kann, beispielsweise bei schnell schaltenden Magnetventilen zur Steuerung von Gaswechselventilen.It should be expressly understood that the principle of decoupling a mass in moving switching elements can be transferred to other switching valves in which by the targeted total mass change, an increase in responsiveness can be achieved, for example, in fast-switching solenoid valves for controlling gas exchange valves.
Zur weiteren Erläuterung der Erfindung wird auf die Zeichnungen verwiesen, in denen ein Ausführungsbeispiel der Erfindung vereinfacht dargestellt ist.For further explanation of the invention reference is made to the drawings, in which an embodiment of the invention is shown in simplified form.

Zum Lösen der Klemmkörper 15 und damit Entriegeln der Aktorstifte 12 wird die nicht dargestellte Elektromagneteinheit bestromt, so dass diese die Dauermagnete 8 und die Stahlscheiben 9 anzieht und damit die Steuernadeln 1 mit Federteller 6 gegen die Kraft der Feder 18 anhebt. Durch das erfindungsgemäße Entkoppeln der Dauermagnete 8 und der Stahlscheiben 9 ist auch das Entriegeln der Steuernadeln 1 schneller geworden, da die Elektromagneteinheit zunächst nur die Dauermagnete 8 und die Stahlscheiben 9 bewegen muss, die dann, bereits beschleunigt, schneller und sicherer die Steuernadeln 1 verschieben und die Federn 18 zusammendrücken können. Haben sich die Aktorstifte 12, z.B. hervorgerufen durch Vibrationen der Hubkolbenbrennkraftmaschine, aus ihrer inneren Lage nach außen verschoben und werden z.B. durch eine Auswurframpe der Verschiebenut einen kurzen oder einen längeren Weg im Normalbetrieb zurückgeschoben, sind die Steuernadeln 1 belastet durch die Federn 18 jederzeit in der Lage kurzfristig eine Arretierung der Klemmkörper 15 vorzunehmen, da die Federn 18 nur den Federteller 6 und die Steuernadel 1 beschleunigen müssen.To release the clamping
