Sicherungsanordnung für die Kugelgelenklagerung von Schwinghebeln, vorzugsweise für Ventilsteuerungen vonSecuring arrangement for the ball joint bearing of rocker arms, preferably for valve controls of
BrennkraftmaschinenInternal combustion engines
Die Erfindung betrifft eine Sicherungsanordnung für die Kugelgelenklagerung von Schwinghebeln, vorzugsweise für Ventilsteuerungen von Brennkraftmaschinen gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a securing arrangement for the ball joint bearing of rocker arms, preferably for valve controls of internal combustion engines according to the preamble of the main claim.
Vorbekannt ist eine Ausführung einer Sicherungsanordnung für die Kugelgelenklagerung von Schwinghebeln durch die DE-OS 2 008 944, Fig. 1. Ein Sicherungselement ist unterhalb des ortsfesten Kugelkopfes am Lager befestigt und als Bogenfeder ausgebildet. Das seiner Befestigung entgegengesetzte Ende des federnden Bogens umspannt das Ende des Schwinghebels mit der Lagermulde für den Kugelkopf und greift auf der dem Ventil zugewandten Seite der Lagermulde am Schwinghebel kraftschlüssig an. Auf diese Weise wird der Schwinghebel mit seiner Lagermulde im kraftschlüssigen Kontakt mit dem ortsfesten Kugelkopf gehalten. Die Befestigung des Sicherungseiementes ist aufwendig und seine kraftschlüssige Einwirkung und Belastung durch den Schwinghebelhub als wechselbelastetes Federelement ungünstig.A design of a securing arrangement for the ball joint bearing of rocker arms is already known from DE-OS 2 008 944, Fig. 1. A securing element is attached to the bearing below the stationary ball head and is designed as a bow spring. The end of the springy bow opposite its attachment spans the end of the rocker arm with the bearing recess for the ball head and engages the rocker arm on the side of the bearing recess facing the valve in a force-locking manner. In this way, the rocker arm with its bearing recess is held in force-locking contact with the stationary ball head. Attaching the securing element is complex and its force-locking effect and loading through the rocker arm stroke as an alternatingly loaded spring element is unfavorable.
Der Erfindung liegt die Aufgabe zugrunde, eine Sicherungsanordnung zu schaffen, welche für das Halten des Schwinghebels auf dem ortsfesten Kugelkopf ein nicht kraftschlüssig beanspruchtes und nicht hubbeaufschlagtes Sicherungselement aufweist.The invention is based on the object of creating a securing arrangement which has a securing element that is not subjected to force-locking and is not subjected to stroke for holding the rocker arm on the stationary ball head.
Erfindungsgemäß wird diese Aufgabe durch ein gemäß dem Hauptanspruch gestaltetes Sicherungselement und eine angepaßte Formgestaltung des Schwinghebels gelöst.According to the invention, this object is achieved by a securing element designed according to the main claim and an adapted shape of the rocker arm.
Das Sicherungselement verläuft im zusammengesetzten Zustand von Schwinghebel und
ortsfestem Kugelkopf unterhalb dessen größtem Kugeldurchmesser und sichert auf diese
Weise die Gelenkverbindung formschlüssig gegen Abheben. Eine Beanspruchung des
Sicherungselementes durch den Schwinghebelhub erfolgt nicht.The safety element runs in the assembled state of the rocker arm and
fixed ball head below its largest ball diameter and secures on this
The joint connection is positively secured against lifting. A stress on the
The locking element is not activated by the rocker arm stroke.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den abhängen Ansprüchen sowie dem nachfolgend anhand einer Zeichnung näher erläuterten Ausführungsbeispiel der Erfindung.Further advantages and features of the invention emerge from the dependent claims and the embodiment of the invention explained in more detail below with reference to a drawing.

Es weist einen Schwenkbügelabschnitt 41 auf, an dem sich beidseitig spreizbare Raststege 42 anschließen.Fig.1 shows a securing element 4 in a schematic, perspective view. It is U-shaped and made of springy material. It has a swivel bracket section 41, to which locking webs 42 that can be spread are connected on both sides.
Sie weisen einen Abstand A zueinander auf, der geringer als ein Kugeidurchmesser D3 des
Kugelkopfes 3 ist, jedoch bei elastischer Verformung das Durchdrücken dieses Kugelkopfes
3 gestattet. Weiterhin sind die Raststege 42 mit nach oben sowie in Richtung des
Schwenkbügelabschnittes 41 gekröpften Schenkeln 43 ausgestattet.They have a distance A from each other that is less than a ball diameter D3 of the ball head 3, but allows the ball head 3 to be pushed through when elastically deformed. Furthermore, the locking webs 42 are provided with upwards and in the direction of the
Swivel bracket section 41 is equipped with cranked legs 43.

Der innere Haltesteg 22 kann an seiner zur Öffnungsebene 20 winkligen Seite Nuten 23 aufweisen, in welche die gekröpften Schenkel 43 des Sicherungselementes 4 eingreifen und dabei in dem Abstand A zueinander gehalten werden.The inner retaining web 22 can have grooves 23 on its side at an angle to the opening plane 20, into which the cranked legs 43 of the securing element 4 engage and are held at a distance A from one another.

Ist der innere Haltesteg 22 an seiner zur Öffnungsebene 20 winkligen Seite mit Nuten 23 ausgestattet, in welche die gekröpften Schenkel 42 des Sicherungselementes 4 dann eingreifen, so werden die Schenkel 42 in einem geringeren Abstand A als der Kugeldurchmesser D3 arretiert.If the inner retaining web 22 is equipped with grooves 23 on its side at an angle to the opening plane 20, into which the cranked legs 42 of the securing element 4 then engage, the legs 42 are locked at a smaller distance A than the ball diameter D3.
Das Sicherungselement 4 wird zum Befestigen am Schwenkhebel 1 mit seinem Schwenkbügelabschnitt 41 auf dem äußeren Haltesteg 21 aufgelegt und in Richtung der Öffnungsebene 20 schwenkend mit seinen gekröpften Schenkeln 43 auf den inneren Haltesteg 22 bis zum Rasten der Kröpfungen 44 aufgeschoben.To be attached to the pivot lever 1, the securing element 4 is placed with its pivot bracket section 41 on the outer retaining web 21 and is pushed with its cranked legs 43 pivoting in the direction of the opening plane 20 onto the inner retaining web 22 until the cranks 44 engage.
Der Einbau des Schwinghebels 1 mit dem Sicherungselement 4 in einen Zylinderkopf einer Brennkraftmaschine erfolgt durch Aufdrücken des Lagermuldenkopfes 2 auf den ortsfest angeordneten Kugelkopf 3 der Kugelgelenklagerung.The installation of the rocker arm 1 with the securing element 4 in a cylinder head of an internal combustion engine is carried out by pressing the bearing recess head 2 onto the fixed ball head 3 of the ball joint bearing.
Im Betrieb der Brennkraftmaschine wird eine Rolle 5 des Schwinghebels 1 von einer Nocke einer nicht gezeigten Nockenwelle periodisch betätigt, wodurch dieser um den ortsfesten Kugelkopf 3 verschwenkt wird und dabei mit seinem in Figur 3 links liegenden Ende ein nicht gezeigtes Gaswechselventil betätigt. Vorteilhafterweise wird durch diese Schwenkbewe-When the internal combustion engine is in operation, a roller 5 of the rocker arm 1 is periodically actuated by a cam of a camshaft (not shown), whereby the rocker arm is pivoted around the stationary ball head 3 and thereby actuates a gas exchange valve (not shown) with its end on the left in Figure 3. This pivoting movement advantageously
gungen das Sicherungselement (4) nicht belastet, es führt lediglich eine geringfügige Relativbewegung zum Kugelkopf (3) aus.the securing element (4) is not loaded, it only carries out a slight relative movement to the ball head (3).
Weiterhin vorteilhaft ist, daß durch diese druckknopfartige Sicherung des Schwinghebels auf dem Kugelkopf 3 ein seitliches Herunterfallen bei Montage bzw. Demontage sicher verhindert ist.Another advantage is that this push-button-like securing of the rocker arm on the ball head 3 reliably prevents it from falling sideways during assembly or disassembly.
