Description
Die Erfindung bezieht sich auf eine Nockenwellenverstelleinheit für Hubkolbenbrennkraftmaschinen mit einem Nockenwellenversteller, dessen Verdrehbewegung von einem hydraulischen Steuerventil mit einem axial verschiebbaren, federbelasteten Steuerkolben beherrscht ist, mit einer maschinenfest angeordneten, elektromagnetischen Betätigungseinheit, die einen längs verschiebbaren Anker aufweist, und mit einer Stößelstange, die zwischen dem Anker und dem Steuerkolben angeordnet ist.The invention relates to a Nockenwellenverstelleinheit for reciprocating internal combustion engines with a camshaft adjuster whose rotational movement is dominated by a hydraulic control valve with an axially displaceable, spring-loaded control piston, with a fixed machine, electromagnetic actuator unit having a longitudinally displaceable armature, and with a push rod, the is arranged between the armature and the control piston.
Derartige Nockenwellenverstelleinheiten sind allgemein bekannt. Die Nockenwellenverstelleinheit gemäß
Aufgabe der Erfindung ist es daher, eine Nockenverstelleinheit der eingangs beschriebenen Art zur Verfügung zu stellen, bei der die beschriebenen Nachteile behoben werden. Dies soll mit einfachen kostengünstigen Mitteln erfolgen.The object of the invention is therefore to provide a Nockenverstelleinheit of the type described above, in which the disadvantages described are eliminated. This should be done with simple inexpensive means.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Stößelstange am Anker und am Steuerkolben schwenkbar und am Anker und/oder Steuerkolben drehbar gelagert ist. Dadurch kann die schwenkbare Stößelstange möglichen Achsversatz ausgleichen. Dabei weist der Anker eine tiefe, mit sicherem Abstand bis zur inneren Wand des Ankers reichende Ausnehmung auf, deren Wände in Richtung zum Steuerventil kegelig sich erweiternd ausgeführt sind. Der Anker wird nur einmal am äußeren Bereich in der Betätigungseinheit gelagert. Dadurch, dass die Stößelstange in der Tiefe des Ankers, die durch die Ausnehmung gegeben ist, angreift, treten auf den Anker keine Kippkräfte auf, so dass die Lagerung des Ankers entlastet ist. Der Abstand der Ausnehmung von der hinteren Wand des Ankers ist so gewählt, dass eine hinreichende Sicherheit auch gegen Verschleiß gegeben ist. Die Stößelstange ist in ihrer Schwenkbewegung komplett frei. Am Grund der Ausnehmung im Anker ist vorzugsweise eine Kugelkalotte eingearbeitet. Es können aber auch andere Kontaktierungen zwischen dem Grund der Ausnehmung und der Stößelstange vorgesehen sein. Die Stößelstange hat zumindest an einem Ende, vorzugsweise an beiden Enden, einen Kugelkopf, der zu verschiedenen Schalenformen passt. Am Steuerkopf des Steuerkolbens ist ebenfalls eine Kugelkalotte oder eine kegelige Vertiefung angebracht, die mit dem Ende der Stößelstange in Verbindung steht. Im Steuerkopf kann auch eine Öffnung/Bohrung eingearbeitet sein, wobei deren Durchmesser kleiner ist als die maximale Abmessung des Endes der Stößelstange oder des Kugelkopfes an der Stößelstange. Dadurch ist eine gute Fixierung der Stößelstange am Steuerkolben gegeben.According to the invention the object is achieved in that the push rod is pivotally mounted on the armature and the control piston and rotatably mounted on the armature and / or control piston. As a result, the pivotable push rod can compensate for possible misalignment. In this case, the armature has a deep, with a safe distance to the inner wall of the armature reaching recess whose walls are designed to be conically widening in the direction of the control valve. The anchor is stored only once at the outer area in the actuator unit. Characterized in that the push rod engages in the depth of the armature, which is given by the recess, no tilting forces occur on the armature, so that the bearing of the armature is relieved. The distance of the recess from the rear wall of the armature is chosen so that a sufficient security is also given against wear. The push rod is completely free in its pivoting movement. At the bottom of the recess in the anchor is preferably incorporated a spherical cap. But it may also be provided other contacts between the bottom of the recess and the push rod. The push rod has at least at one end, preferably at both ends, a ball head which fits into different shell shapes. On the control head of the control piston, a spherical cap or a conical recess is also attached, which is in communication with the end of the push rod. In the control head can also be incorporated an opening / bore, wherein the diameter of which is smaller than the maximum dimension of the end of the push rod or the ball head on the push rod. As a result, a good fixation of the push rod on the control piston is given.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass am/im Steuerkolben eine Aufnahmescheibe für die Stößelstange eingebaut ist, die ihrerseits eine passende Kugelkalotte, eine kegelige Vertiefung oder eine Öffnung/Bohrung zur Aufnahme der Stößelstange aufweist. Da bei dieser Ausgestaltung der Steuerkopf entfällt und die Aufnahmescheibe tief in den Steuerkolben eingebaut werden kann, wird auch die Lagerung des Steuerkolbens im Steuerventil gegen Kippmomente entlastet. Die Aufnahmescheibe hat Durchtrittsöffnungen, damit Hydraulikfluid aus dem Steuerkolben entweichen kann, was wichtig ist, wenn das Innere des Steuerkolbens mit dem Tankanschluss verbunden ist. Die Aufnahmescheibe kann an einer Stufe in einer Öffnung im Steuerkolben anliegen, sie kann eingeklipst oder eingepresst festgelegt sein.In a further embodiment of the invention it is proposed that on / in the control piston a receiving disc for the push rod is installed, which in turn has a matching spherical cap, a conical recess or an opening / hole for receiving the push rod. Since in this embodiment, the control head is eliminated and the receiving disk can be installed deep into the control piston, the storage of the control piston in the control valve is relieved against overturning moments. The pick-up disc has passages to allow hydraulic fluid to escape from the spool, which is important when the interior of the spool is connected to the tank port. The receiving disc may abut against a step in an opening in the control piston, it may be clipped or pressed fixed.
Insbesondere für Montagezwecke ist es wichtig, dass die Stößelstange unverlierbar an einem Bauteil festgelegt ist. Zu diesem Zweck weist die Stößelstange dem Rand der Ausnehmung des Ankers benachbart, eine Haltescheibe auf. In particular, for mounting purposes, it is important that the push rod is fixed captive on a component. For this purpose, the push rod adjacent to the edge of the recess of the armature, a holding disc.
Weiterhin ist an dem dem Steuerventil benachbarten Ende der Betätigungseinheit ein Ring fixiert. Dadurch, dass die Außenabmessung der Haltescheibe größer ist als die Öffnung in dem Ring, ist die Stößelstange an der Betätigungseinheit verliersicher befestigt. Furthermore, a ring is fixed to the control valve adjacent the end of the actuating unit. Characterized in that the outer dimension of the retaining plate is larger than the opening in the ring, the push rod is secured captively to the operating unit.
