A wheel (5) with radial vanes (4) is pref. mounted on the shaft, the vanes working in compartments (6) in a second wheel. The two wheels are adjustable for angle w.r.t. each other by hydraulic pressure, the vaned one assuming an initial position (A) on starting. A locking device (13) secures the wheels together in the initial position. It pref. comprises a sliding splined sleeve on one of the wheels, corotating with it and engaging mating grooves in the other wheel. ADVANTAGE - Simple and reliable prevention of a relative wheel motion on starting.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur hydraulischen Drehwinkelverstellung einer Welle relativ zu einem Antriebsrad, insbesondere Nockenwelle für Brennkraftmaschinen gemäß den im Oberbegriff des Patent­ anspruches 1 angegebenen Merkmalen.The invention relates to a device for hydraulic rotation angle adjustment of a shaft relative to a drive wheel, in particular camshaft for Internal combustion engines in accordance with the preamble of the patent Claim 1 specified features.

Eine derartige Vorrichtung ist beispielsweise aus der US-A-31 09 417 bekannt. Bei dieser und anderen bekannten Vorrichtungen unterteilt jeder Flügel des Flügelrades eine Zelle im Zellenrad in zwei gegeneinander relativ abgedichtete Kammern, von denen zumindest eine druck­ beaufschlagt ist. Bei Stillsetzung der Maschine fließt das Druckmedium aus den Kammern über vorgesehene Versor­ gungsleitungen und/oder Entleerungsleitungen sowie über Leckspalte ab.Such a device is for example from the US-A-31 09 417 known. In this and other known ones Devices divide each wing of the impeller a cell in the cell wheel in two relative to each other sealed chambers, at least one of which is pressure is acted upon. When the machine is stopped, flows the pressure medium from the chambers via the provided supplier supply lines and / or drain lines and over Leakage gaps.

Mit den im wesentlichen vom Druckmedium entleerten Kammern ergeben sich beim Ingangsetzen der Maschine und hierbei insbesondere bei maschineninterner Versorgung der Vorrichtung mit dem Druckmedium unerwünschte Rela­ tivdrehbewegungen zwischen Flügelrad und Zellenrad mit nachteilig hohen mechanischen Belastungen. Das Leer­ laufen der Kammern mittels Ventilen in den weiter o. g. Leitungen zu vermeiden, erfordert die Beseitigung sämtlicher Leckspalte in der Vorrichtung, wodurch für diese in nachteiliger Weise ein erheblicher zusätzlicher Bauaufwand anfällt.With those essentially drained from the pressure medium Chambers arise when starting the machine and in this case especially with internal machine supply the device with the print medium undesirable Rela tiv rotation between the impeller and cellular wheel with disadvantageously high mechanical loads. The emptiness run the chambers by means of valves in the further above. Avoiding cables requires elimination  all leakage gaps in the device, making for this disadvantageously a significant additional Construction costs are incurred.

Der Erfindung liegt die Aufgabe zugrunde, für eine gattungsgemäß ausgebildete Vorrichtung eine Maßnahme aufzuzeigen, durch die nachteilige Relativdrehbewegungen zwischen Flügelrad und Zellenrad beim Starten der Maschine mit einfachen Mitteln sicher vermieden sind.The invention is based, for one Generically designed device a measure to show through the disadvantageous relative rotary movements between impeller and cellular wheel when starting the Machine are safely avoided with simple means.

Gelöst wird diese Aufgabe gemäß dem Kennzeichen des Patentanspruches 1 dadurch, daß eine Sperreinrichtung zur Verriegelung des Flügelrades in der Ausgangsstellung mit dem Zellenrad vorgesehen ist.This task is solved according to the characteristic of Claim 1 characterized in that a locking device for locking the impeller in the starting position is provided with the cellular wheel.

Die Erfindung ermöglicht in vorteilhafter Weise mit einfachen Mitteln beim Ingangsetzen bzw. Starten der Maschine eine Relativdrehung zwischen Flügelrad und Zellenrad der Vorrichtung zu vermeiden.The invention advantageously enables using simple means when starting or starting the Machine a relative rotation between the impeller and Avoid the cell wheel of the device.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben. So ist ein Vorschlag darauf gerichtet, die Sperreinrichtung als eine in der Vor­ richtung zentrisch angeordnete und verschiebebewegliche Sperrhülse auszubilden. Mit dieser Ausbildung verbindet sich neben hoher Festigkeit ein einfacher Aufbau, insbesondere in Verbindung mit der Betätigung für die Sperrfunktion. Eine platzsparende, einfache Anordnung der Sperrhülse ist mit Vorteil in der Nabe eines Flügel­ rades erzielt. Diese Kombination ist weiter vorteilhaft bei einem auf der Flügelrad-Nabe zentrierten Zellenrad für die kompakte Anordnung einer Hydraulik-Steuerein­ richtung in der Flügelrad-Nabe, wobei mit der Verwendung eines axial verschiebebeweglichen Steuerschiebers diesem zumindest für eine Richtung die Betätigung der Sperr­ hülse zugeordnet werden kann. In die Gegenrichtung können Sperrhülse und Steuerschieber nach einem weiteren Vorschlag jeweils gesondert federbeaufschlagt sein für den Fall eines einfachen, kostengünstigen Stellmotors für den Stellschieber.Advantageous embodiments of the invention are in the Subclaims described. So that's a suggestion directed the locking device as one in the front direction centrally arranged and movable Form locking sleeve. Connects with this training in addition to high strength, a simple structure, especially in connection with the actuation for the Lock function. A space-saving, simple arrangement the locking sleeve is advantageously in the hub of a wing wheel achieved. This combination is further advantageous with a cell wheel centered on the impeller hub for the compact arrangement of a hydraulic control unit direction in the impeller hub, with use an axially displaceable control spool this actuating the lock at least in one direction sleeve can be assigned. In the opposite direction  can lock sleeve and spool valve after another Proposal should be spring loaded for each the case of a simple, inexpensive servomotor for the setting slide.

Eine lediglich abschnittsweise gezeigte Nockenwelle 1 einer nicht dargestellten Brennkraftmaschine ist mit einer Vorrichtung 2 zur hydraulischen Drehwinkelverstel­ lung der Nockenwelle 1 gegenüber einem Antriebsrad 3 ausgerüstet. Die hydraulisch zweiseitig beaufschlagbare Vorrichtung 2 umfaßt ein nockenwellenseitig angeordne­ tes, radiale Flügel 4 tragendes Flügelrad 5 und ein mit dem Antriebsrad 3 drehfest verbundenes, die Flügel 4 in umfänglich verteilt angeordneten Zellen 6 aufnehmendes Zellenrad 7. Das Flügelrad 5 weist ferner eine die Flügel 4 tragende Nabe 8 auf, über die das Flügelrad 5 mit der Nockenwelle 1 drehfest verbunden ist. Wie ferner aus den Fig. 2 und 4 hervorgeht, ist das jeweilige Zellenrad 7 auf der Nabe 8 des Flügelrades 5 zentriert und drehwinkelbeweglich gelagert. A camshaft 1, shown only in sections, of an internal combustion engine, not shown, is equipped with a device 2 for hydraulic adjustment of the rotation angle of the camshaft 1 relative to a drive wheel 3 . The hydraulically double-sided device 2 comprises an arranged on the camshaft side, radial vane 4 carrying impeller 5 and a rotatably connected to the drive wheel 3 , the vanes 4 in circumferentially distributed cells 6 receiving cell wheel 7th The impeller 5 also has a hub 8 carrying the vanes 4 , via which the impeller 5 is connected to the camshaft 1 in a rotationally fixed manner. As can also be seen from FIGS. 2 and 4, the respective cellular wheel 7 is centered on the hub 8 of the impeller 5 and is mounted such that it can be rotated by an angle.

Eine Drehwinkelverstellung der Nockenwelle 1 relativ zum Antriebsrad 3 erfolgt über die Vorrichtung 2, indem Drucköl aus einem Schmierölkreislauf der Brennkraftma­ schine über ein Lager 9 der Nockenwelle 1 und einer in der Flügelrad-Nabe 8 angeordneten Hydraulik-Steuerein­ richtung 10 in von den Flügeln 4 in den Zellen 6 gebil­ deten Kammern 11 oder 12 geleitet wird. Um bei fehlendem Drucköl, insbesondere in der Startphase der Brennkraft­ maschine eine Relativdrehung zwischen Flügelrad 4 bzw. Nockenwelle 1 und dem Zellenrad 7 bzw. dem Antriebsrad 3 zu vermeiden, ist die Vorrichtung 2 mit einer Sperrein­ richtung 13 zur Verriegelung des Flügelrades 5 in der Ausgangsstellung "A" mit dem Zellenrad 7 ausgerüstet.A rotation angle adjustment of the camshaft 1 relative to the drive wheel 3 takes place via the device 2 , by pressurized oil from a lubricating oil circuit of the internal combustion engine via a bearing 9 of the camshaft 1 and a hydraulic control device 10 arranged in the impeller hub 8 in from the vanes 4 in the cells 6 gebil Deten chambers 11 or 12 is passed. In order to avoid a relative rotation between the impeller 4 or camshaft 1 and the cellular wheel 7 or the drive wheel 3 in the absence of pressure oil, in particular in the starting phase of the internal combustion engine, the device 2 is equipped with a locking device 13 for locking the impeller 5 in the starting position "A" equipped with cellular wheel 7 .

Die Sperreinrichtung 13 umfaßt eine im Zellenrad 7 koaxial und über ein Sperrprofil 14 drehfest angeordne­ te, verschiebebewegliche Sperrhülse 15, die in Ausgangs­ stellung "A" des Flügelrades 5 in eine mit dem Sperr­ profil 14 fluchtende Sperrnut 16 des Flügelrades 5 einrastet. Das Einrasten der Sperrhülse 15 zur gegen­ seitigen Dreh-Verriegelung von Flügelrad 5 und Zellen­ rad 7 wird mittels einer vorgespannt angeordneten Feder 17 bewirkt. Voraussetzung hierfür ist jedoch, daß ein in der Flügelrad-Nabe 8 koaxial angeordneter Steuer­ schieber 18 der Hydraulik-Steuereinrichtung 10 in einer das Füllen mit Drucköl der Kammern 11 für eine Drehwin­ kelverstellung in Drehrichtung gemäß Pfeil "B" unter­ bindenden Endposition angeordnet ist. Diese Positionie­ rung des Steuerschiebers 18 wird bei einem lediglich in einer Richtung wirkenden Hubmagneten 19 als Stellmo­ tor 20 mittels einer weiteren, vorgespannt angeordneten Feder 21 bewirkt.The blocking device 13 comprises a rotationally fixed in the feeder 7 coaxially and a lock-up profile 14 is arrange te, shifting movable locking sleeve 15, which engages in the output "A" position of the impeller 5 into alignment with the locking profile 14 the lock groove 16 of the impeller. 5 The locking of the locking sleeve 15 to counter-rotating locking of the impeller 5 and cell wheel 7 is effected by means of a biased spring 17 . The prerequisite for this, however, is that a in the impeller hub 8 coaxially arranged control slide 18 of the hydraulic control device 10 in a filling with pressure oil of the chambers 11 for a rotation angle adjustment in the direction of rotation according to arrow "B" is arranged under binding end position. This Positionie tion of the spool 18 is effected with a solenoid 19 acting only in one direction as a Stellmo gate 20 by means of a further, biased arranged spring 21 .

Wie aus den Fig. 1 und 3 ersichtlich, sind Sperrhülse 15 und Steuerschieber 18 zueinander koaxial angeordnet. Der Steuerschieber 18 ist mit einem Bund 22 ausgebildet, gegen den die Sperrhülse 15 beim Verriegeln von Flügel­ rad 5 und Zellenrad 7 anschlägt.As can be seen from FIGS . 1 and 3, the locking sleeve 15 and control slide 18 are arranged coaxially with one another. The control slide 18 is formed with a collar 22 against which the locking sleeve 15 strikes when locking the wing wheel 5 and cellular wheel 7 .

Hat sich nach dem Start der Brennkraftmaschine in deren Schmierölkreislauf ein ausreichender Druck aufgebaut, erfolgt lastpunktabhängig eine Entriegelung von Flügel­ rad 5 und Zellenrad 7 zur Einleitung einer gewünschten Drehwinkelverstellung der Nockenwelle 1 gegenüber dem Antriebsrad 3. Hierfür wird der Steuerschieber 18 über den Stellmotor 20 in die entgegengesetzte Endposition verlagert, wobei mit dieser Verlagerung die Sperrhül­ se 15 mittels des Bundes 22 aus der Sperrstellung in das Zellenrad 7 mitgenommen ist.Has sufficient pressure built up in the lubricating oil circuit after the start of the internal combustion engine, depending on the load point, the wing wheel 5 and cellular wheel 7 are unlocked to initiate a desired rotation angle adjustment of the camshaft 1 relative to the drive wheel 3 . For this purpose the control slide valve 18 is displaced via the control motor 20 in the opposite end position, wherein with this displacement, the Sperrhül se 15 by means of the collar 22 from the locking position into the feeder 7 is taken.

Das Sperrprofil 14 der Sperrhülse 15 ist vorzugsweise eine Geradverzahnung mit einer Zahnteilung, die eine Zahn-Gegen-Zahn-Anordnung außerhalb der Sperrstellung bewirkt.The locking profile 14 of the locking sleeve 15 is preferably a straight toothing with a tooth pitch, which causes a tooth-against-tooth arrangement outside the locking position.

Schließlich umfaßt der als Stellmotor 20 für den Steuer­ schieber 18 vorgesehene Hubmagnet 19 eine gehäusefest angeordnete Ringspule 23, in die ein mit dem Steuer­ schieber 18 mitdrehender Tauchkolben 24 bei Anliegen einer signalgesteuerten Spannung eintaucht.Finally, the lifting magnet 19 provided as a servomotor 20 for the control slide 18 comprises an annular coil 23 fixed to the housing, into which a plunger 24 rotating with the control slide 18 is immersed when a signal-controlled voltage is applied.

Die Vorrichtung der Fig. 3 und 4 weist gegenüber der Vorrichtung der Fig. 1 und 2 eine ungesteuerte Ent­ leerung der Kammern 12 auf.The device of FIGS. 3 and 4 has an uncontrolled emptying of the chambers 12 compared to the device of FIGS. 1 and 2.
