Abstract

The invention relates to a switchable cam follower of a valve train of an internal combustion engine, comprising an outer follower and an inner follower interposed between the lateral walls thereof. A roller extends between arms of the inner follower, float-mounted on a pin, as the counter face for an eccentric disk. The followers are disposed on one end on a common axis. On the distal end, they have elongate seats that, at the base of the cam, are mutually aligned. A coupling element is located in the seat of the outer follower and can be displaced step by step into the seat (here follower surface) of the inner follower. The pin on the inner follower slightly projects over the arms of the inner follower with one projection each. When coupled, upper sides of the projections rest against lower sides of stop surfaces that are mounted on the inner surfaces of the lateral walls of the outer follower.

Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft einen schaltbaren Schlepphebel eines Ventiltriebs einer Brennkraftmaschine, mit einem Außen- und einem zwischen dessen Seitenwänden angeordneten Innenhebel, welcher Innenhebel eine auf einem Bolzen gelagerte Rolle als Gegenlauffläche für einen Hubnocken zwischen seinen Armen besitzt, wobei dem Schlepphebel an einer Unterseite an einem Ende eine Anlage für ein Gaswechselventil und am anderen Ende ein Schwenklager immanent sind, wobei die Hebel an einem der Enden auf einer gemeinsamen Achse verlaufen und an dem der Achse abgewandten Ende sich längs erstreckende, im Nockengrundkreis zueinander fluchtende Aufnahmen haben, wobei in wenigstens einer der Aufnahmen ein Koppelmittel angeordnet ist, das für eine Kopplung der Hebel abschnittsweise in die gegenüberliegende Aufnahme verlagerbar ist (siehe US-A-5 544 626 ).The invention relates to a switchable rocker arm of a valve train of an internal combustion engine, with an outer and between the side walls arranged inner lever, which inner lever has a roller mounted on a pin as a mating surface for a lifting cam between his arms, the rocker arm on a bottom at one end a system for a gas exchange valve and at the other end a pivot bearing are immanent, wherein the levers extend at one of the ends on a common axis and at the end facing away from the axis longitudinally extending, in the cam base circle aligned receptacles, wherein in at least one of the receptacles a coupling means is arranged, which is for a coupling of the lever in sections displaceable in the opposite receptacle (see US-A-5 544 626 ).

Hintergrund der ErfindungBackground of the invention

Um eine fluchtende Position von Aufnahmen für Koppelmittel im Nockengrundkreis bei aus dem Stand der Technik vorbekannten Hebeln darzustellen, hat ein jeweiliger Außenhebel einen den entsprechenden Innenhebel in etwa im Bereich einer Quermittelebene bügelartig untergreifenden Anschlag. Aufgrund der notwendigen Übergangsradien dieses bügelartigen Anschlags von den Armen des Außenhebels in Querrichtung gesehen muss ein derartiger Schlepphebel relativ breit bauen, da der Innenhebel nicht im Radienbereich auf eine Oberseite des Querbügels anschlagen kann. Sollte dennoch ein Anschlagen im Bereich der Radien erfolgen, ist mit einer unnötig hohen Materialbelastung zu rechnen. Auch können Zustände auftreten, bei denen keine ausreichende Fluchtung des Koppelmittels zur gegenüberliegenden Aufnahme gegeben ist, so dass eine Kopplung nicht realisiert werden kann.In order to represent an aligned position of receptacles for coupling means in the cam base circle in previously known from the prior art levers, a respective outer lever has a corresponding inner lever approximately in the region of a transverse center plane bow-like cross-stop. Due to the necessary transition radii of this bow-shaped stopper seen from the arms of the outer lever in the transverse direction, such a drag lever must build relatively wide, since the inner lever can not strike in the radius range on an upper side of the cross bar. However, should a stop occur in the area of the radii, an unnecessarily high material load is to be expected. Also, conditions may occur in which there is no sufficient alignment of the coupling means for opposing recording, so that a coupling can not be realized.

Zum anderen liegt auf der Hand, dass aufgrund des die Unterseite des Innenhebels übergreifenden Querbügels der Schlepphebel unnötig tief baut. Hier können Freigängigkeitsprobleme im Zylinderkopfbereich auftreten.On the other hand, it is obvious that due to the bottom bracket of the inner lever crossbar of the drag lever builds unnecessarily deep. Here, clearance problems in the cylinder head area can occur.

Nachteilig ist es des Weiteren, dass der Bolzen für die Rolle als Gegenlaufflächen im Innenhebel verstemmt oder anderweitig mit dem Innenhebel befestigt werden muss. Dies erhöht den Fertigungsaufwand. Zudem ist die Rolle mit Bolzen nach erstmaliger Befestigung nicht wieder demontierbar. Eine Demontage wäre jedoch ggf. für den Service-Fall bzw. für den Fall einer Zupaarung von vorsortierten Rollen zur Spieleinstellung wünschenswert.Another disadvantage is that the bolt for the role caulked as mating surfaces in the inner lever or otherwise must be attached to the inner lever. This increases the production costs. In addition, the role with bolts after initial attachment is not removable again. A disassembly would, however, if necessary, desirable for the service case or in the case of a pairing of presorted rollers for game adjustment.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es daher, einen Schlepphebel der vorgenannten Gattung zu schaffen, bei dem die aufgeführten Nachteile beseitigt sind.The object of the invention is therefore to provide a drag lever of the aforementioned type, in which the disadvantages listed are eliminated.

Lösung der AufgabeSolution of the task

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Bolzen im Innenhebel "fliegend" gelagert ist und mit je einem Ansatz geringfügig über die Arme des Innenhebels hinaussteht, wobei im Koppelfall Oberseiten der Ansätze an Unterseiten von Anschlagflächen anliegen, die an Innenflächen der Seitenwände des Außenhebels appliziert sind.According to the invention, this object is achieved in that the bolt is "flying" mounted in the inner lever and slightly protrudes with one approach over the arms of the inner lever, wherein in the coupling case tops of the lugs abut surfaces of abutment surfaces, which are applied to inner surfaces of the side walls of the outer lever are.

Somit sind die vorbeschriebenen Nachteile beseitigt. Der Schutzbereich dieser Erfindung bezieht sich auch auf Lösungen an schaltbaren Schlepphebeln, bei denen eine so genannte "Querverriegelung" appliziert ist. Aufgrund der internen Anschlagmaßnahmen, die vorzugsweise von Innenflächen von Seitenwänden des Außenhebels einteilig ausgehen, kann auf den vorgenannten bügelartigen Anschlag, welcher den Innenhebel untergreift, verzichtet werden. Der Bolzen für die Rolle wird demnach geringfügig breiter als der Innenhebel gestaltet, so dass dessen Oberseiten in einfacher Art und Weise an Unterseiten der Anschlagflächen im Koppelfall anliegen. Somit wird eine Fluchtung der Aufnahmen für die Koppelmittel im Nockengrundkreis geschaffen. Gleichzeitig kann über diese Anschlagmaßnahmen eine Freigängigkeit der Gegenlauffläche des Innenhebels im Nockengrundkreis in Bezug auf deren Nocken realisiert werden. Durch letztgenannte Maßnahme wird eine konstruktive Überbestimmung vermieden und gleichzeitig Grundkreisreibung reduziert.Thus, the above-described disadvantages are eliminated. The scope of this invention also relates to solutions to switchable drag levers in which a so-called "cross-lock" is applied. Due to the internal stop measures, which preferably start in one piece from inner surfaces of side walls of the outer lever, can be dispensed with the aforementioned bow-shaped stop which engages under the inner lever. The bolt for the role is therefore slightly wider than the inner lever designed so that the tops abut in a simple manner on the undersides of the stop surfaces in the coupling case. Thus, an alignment of the images for the coupling means in the cam base circle is created. At the same time a clearance of the mating surface of the inner lever in the cam base circle with respect to the cam can be realized on these stop measures. By the latter measure a constructive over-determination is avoided and at the same time base circle friction is reduced.

Unter der Bezeichnung "fliegend" ist eine Anordnung des Bolzens in der entsprechenden Aufnahme im Innenhebel gemeint, die auf jedwede Befestigung verzichtet. Der Bolzen zentriert sich somit mit seinen Außenstirnseiten an Innenflächen der Seitenwände des Außenhebels selbst.By the term "flying" is meant an arrangement of the bolt in the corresponding receptacle in the inner lever, which dispenses with any attachment. The bolt thus centered with its outer end faces on inner surfaces of the side walls of the outer lever itself.

Zweckmäßigerweise werden Unterseiten der Anschlagflächen, die ggf. auch separat ausgebildet sein können, komplementär zu Oberseiten der Bolzen realisiert.Advantageously, undersides of the abutment surfaces, which may possibly also be formed separately, realized complementary to tops of the bolts.

Anstelle des vorgesehenen "Hubumschalters" als Schlepphebel kann auch ein "Hubabschalter" vorliegen, d.h. im Entkoppelfall der Hebelteile würde keine Öffnung des Gaswechselventils realisiert werden.Instead of the intended "Hubumschalters" as a drag lever may also be a "Hubabschalter", i. In the decoupling of the lever parts no opening of the gas exchange valve would be realized.

Zweckmäßigerweise ragen die Anschlagflächen nur geringfügig von den Innenflächen der Seitenwände des Außenhebels nach innen. In weiterer Fortbildung der Erfindung ist es zudem vorgesehen, die Anschlagflächen einteilig von Oberseiten der Seitenwände des Außenhebels ausgehen zu lassen. Diese können auch einteilig mit Gegenlaufflächen für Niedrighubnocken, die als Gleitflächen ausgebildet sein können, dargestellt werden, so dass im Querschnitt in diesem Bereich ein T- oder eine T-ähnliches Profil vorliegt. Es ist jedoch auch vorgesehen, die Anschlagflächen beabstandet zu den vorgenannten Oberseiten tiefer anzuordnen.Appropriately, the stop surfaces protrude only slightly from the inner surfaces of the side walls of the outer lever inwards. In a further development of the invention, it is also intended to let the stop surfaces in one piece from tops of the side walls of the outer lever. These can also be shown in one piece with mating surfaces for low-lift cams, which can be designed as sliding surfaces, so that there is a T or a T-like profile in cross-section in this region. However, it is also envisaged to arrange the abutment surfaces spaced apart from the abovementioned upper sides.

Auch ist eine Lösung vom Schutzbereich eingeschlossen, bei der am Außenhebel ebenfalls Rollen als Gegenlaufflächen appliziert sind oder bei der lediglich am Außenhebel Rollen als Gegenlaufflächen vorliegen und der Innenhebel mit einer Gleitfläche versehen ist.Also, a solution is included in the scope, are also applied to the outer lever rollers as mating surfaces or in which only on the outer lever rollers are present as mating surfaces and the inner lever is provided with a sliding surface.

Die vorgeschlagene Lost-Motion-Feder baut relativ kompakt. Außerdem ist durch Anlage deren einen Schenkels auf einer Oberseite eines Querstegs des Außenhebels im Entkoppelfall eine "Ausdrehsicherung" für den Innenhebel in Zylinderkopfrichtung geschaffen, derart, dass der Bolzen nicht verloren gehen kann.The proposed lost-motion spring is relatively compact. In addition, by creating a leg on a top of a crosspiece of the outer lever in the decoupling a "Ausdrehsicherung" created for the inner lever in the cylinder head direction, such that the bolt can not be lost.

Anstelle der Drehschenkelfeder als Lost-Motion-Feder können ggf. auch Schraubendruckfedern oder dergleichen eingesetzt werden. Als Schwenklager für den Schlepphebel ist insbesondere an eine Kalotte gedacht. Über diese kann der Schlepphebel auf einem Kopf eines hydraulischen oder mechanischen Abstützelements gelagert sein. Ggf. ist jedoch auch eine Anordnung des Schlepphebels auf einer Schwenkachse o. dgl. denkbar und vorgesehen.Instead of the torsion spring as a lost-motion spring and possibly helical compression springs or the like can be used. As a pivot bearing for the drag lever is especially intended to a dome. About this, the drag lever can be mounted on a head of a hydraulic or mechanical support element. Possibly. However, an arrangement of the finger lever on a pivot axis o. The like. Conceivable and provided.

Eine besonders zweckmäßige Variante einer Zufuhr von Hydraulikmittel zum Schlepphebel zur Verlagerung der Koppelmittel in wenigstens eine Richtung liegt dann vor, wenn das Hydraulikmittel über den Kopf des Abstützelements, das Schwenklager und einen kurzen Hydraulikmittelkanal direkt in die Aufnahme für das Koppelmittel geleitet wird. Der Schlepphebel kann dabei so vorliegen, dass er im drucklosen Zustand entweder mechanisch verriegelt oder mechanisch entriegelt ist.A particularly expedient variant of a supply of hydraulic fluid to the finger lever for displacing the coupling means in at least one direction is present when the hydraulic fluid is passed via the head of the support member, the pivot bearing and a short hydraulic fluid channel directly into the receptacle for the coupling means. The rocker arm can be present so that it is either mechanically locked or mechanically unlocked in the pressureless state.

Ggf. können an dem erfindungsgemäßen Schlepphebel auch weitere Beaufschlagungsmittel für den wenigstens einen Kolben als Koppelmittel vorgesehen sein, so beispielsweise eine beidseitig hydraulische, eine elektromagnetische, eine magnetische und ähnliches.Possibly. may be provided on the rocker arm according to the invention also further biasing means for the at least one piston as coupling means, such as a hydraulic on both sides, an electromagnetic, a magnetic and the like.

Ausführliche Beschreibung der ZeichnungDetailed description of the drawing

Die Figuren offenbaren einen schaltbaren Schlepphebel 1 für einen Ventiltrieb einer Brennkraftmaschine. Dieser hat einen Außenhebel 3. Zwischen Seitenwänden 2 des Außenhebels 3 ist ein Innenhebel 4 gelagert. Dieser weist zwei beabstandete Arme 7 auf, zwischen denen eine Rolle als Gegenlauffläche 6 für einen Großhubnocken verläuft. Diese Rolle ist hier über Wälzkörper auf einem Bolzen 5 gelagert, der "fliegend", demnach nicht befestigt, im Innenhebel 4 verläuft.The figures disclose a switchable drag lever 1 for a valve train of an internal combustion engine. This has an outer lever 3. Between side walls 2 of the outer lever 3, an inner lever 4 is mounted. This has two spaced arms 7, between which runs a role as mating surface 6 for a Großhubnocken. This role is here stored on rolling elements on a bolt 5, the "flying", therefore not fixed, runs in the inner lever 4.

Der Außenhebel 3 hat an einem Ende 11 an einer Unterseite 8 ein als Kalotte ausgebildetes Schwenklager 12. Über dieses ist er auf einem Kopf eines beispielsweise hydraulischen Abstützelements verschwenkbeweglich lagerbar. Am anderen Ende 9 hat der Außenhebel 3 an der Unterseite 8 einen Quersteg 25 mit einer Anlage 10 für ein Gaswechselventil. Ggf. kann der Schlepphebel 1 auch so ausgelegt sein, dass er zur Öffnung mehrerer gleichwirkender Gaswechselventile dient.The outer lever 3 has at one end 11 on an underside 8 designed as a dome pivot bearing 12. About this he is on a head of an example hydraulic support pivotally mounted. At the other end 9, the outer lever 3 on the underside 8 has a transverse web 25 with a system 10 for a gas exchange valve. Possibly. the drag lever 1 may also be designed so that it serves to open a plurality of identical gas exchange valves.

Des Weiteren geht hervor, dass der Außenhebel 3 oberhalb des Schwenklagers 12 eine hier längs verlaufende Aufnahme 13 besitzt. In dieser Aufnahme 13 sitzt im Entkoppelfall ein beispielsweise kolbenartiges Koppelmittel 15. Am anderen Ende 9 ist eine Achse 12a angeordnet, auf welcher die Hebel 3, 4 zueinander relativ verschwenkbeweglich verlaufen.Furthermore, it is apparent that the outer lever 3 has a longitudinally extending receptacle 13 above the pivot bearing 12. In this receptacle 13 sits in a decoupling case, for example, a piston-like coupling means 15. At the other end 9, an axis 12a is arranged, on which the levers 3, 4 extend relative to each other pivotable.

Wie insbesondere Figur 3 offenbart, ist innerhalb der Arme 7 des Innenhebels 4 auf der Achse 12a eine Drehschenkelfeder 22 als Lost-Motion-Feder angeordnet. Dabei ist deren wenigstens einer Schenkel 23 (s. a. Fig. 1) auf einer Oberseite 24 des vorgenannten Quersteges 25 abgestützt. Deren anderer Schenkel 26 wirkt gegen einen Querbalken 27 des Innenhebels 4. Somit ist eine Rückführung des Innenhebels 4 in dessen Abkoppelmodus an seinen Großhubnocken garantiert.In particular FIG. 3 disclosed within the arms 7 of the inner lever 4 on the axis 12a, a torsion spring 22 is arranged as a lost-motion spring. In this case, the at least one leg 23 (see also Fig. 1 ) supported on an upper side 24 of the aforementioned transverse web 25. Their other leg 26 acts against a transverse bar 27 of the inner lever 4. Thus, a return of the inner lever 4 in its Abkoppelmodus is guaranteed at its Großhubnocken.

Zu erkennen ist außerdem (s. insb. Figur 3), dass Oberseiten 20 der Seitenwände 2 des Außenhebels 3 zumindest im Bereich einer Mitte segmentartig nach außen zur Bildung von Gleitflächen als Gegenlaufflächen 21 für Nocken abstehen. Diese Gegenlaufflächen 21 bilden von Innenflächen 19 der Seitenwände 2 abschnittsweise und geringfügig nach innen abstehende Anschlagflächen18.It can also be seen (see esp. FIG. 3 ), that upper sides 20 of the side walls 2 of the outer lever 3 protrude at least in the region of a center segment-like outward to form sliding surfaces as mating surfaces 21 for cams. These mating surfaces 21 form of inner surfaces 19 of the side walls 2 partially and slightly inwardly projecting Anschlagflächen18.

Der Bolzen 5 ragt mit seinen beidendigen Ansätzen 15a geringfügig über die Arme 7 des Innenhebels 4 hinaus. Zur Schaffung einer fluchtenden Position der Aufnahme 13 zu einer Aufnahme 14 an einer Unterseite des Innenhebels 4, schlagen Oberseiten 16 der Ansätze 15a des Bolzens 5 an komplementäre Unterseiten 17 der Anschlagfläche 18 an, wobei hier auch eine Kopplung in eine Bohrung denkbar ist. Bei Nockengrundkreisdurchlauf ist die als Rolle ausgebildete Gegenlauffläche 6 des Innenhebels 4 ohne Nockenkontakt, wobei sich die vorhergehend genannten Gegenlaufflächen 21 am Außenhebel 3 an ihren Nocken abstützen.The bolt 5 protrudes slightly beyond the arms 7 of the inner lever 4 with its both ends 15a. To create an aligned position of the receptacle 13 to a receptacle 14 on an underside of the inner lever 4, strike tops 16 of the lugs 15a of the bolt 5 to complementary lower sides 17 of the stop surface 18, in which case a coupling in a bore is conceivable. When the cam base circle run is designed as a roller mating surface 6 of the inner lever 4 without cam contact, with the aforementioned mating surfaces 21 are supported on the outer lever 3 at its cams.
