Description

Bezeichnung der Erfindung  Name of the invention
Winkelgelenk Beschreibung Angular joint description
Gebiet der Erfindung Die Erfindung betrifft ein Winkelgelenk zur verschwenkbeweglichen Anbindung eines Kugelkopfes an eine Gelenkpfanne, welcher Kugelkopf Bestandteil eines in eine Bohrung eines hebelartigen Nockenfolger eines Ventiltriebs einer Brennkraftmaschine eingebauten Führungsstücks ist und die Gelenkpfanne zu einem Fußstück gehört, welches eine druckkolbenferne Kontaktfläche für ein Gaswechselventilkontakt hat, wobei in einer Ringnut des Winkelgelenks ein radial vorspringendes Ringelement dargestellt ist, über welches Ringelement das Fußstück axial formschlüssig am Kugelkopf gehalten ist. FIELD OF THE INVENTION The invention relates to an angle joint for the swiveling connection of a ball head to a socket, which ball is part of a built into a bore of a lever-like cam follower of a valve train of an internal combustion engine leader and the socket belongs to a foot piece, which has a pressure piston remote contact surface for a gas exchange valve contact , wherein in a ring groove of the angle joint, a radially projecting ring element is shown, via which ring element, the foot piece is held axially positively on the ball head.
Ein derartiges Winkelgelenk geht aus der DE 10 2008 048 515 A1 hervor. Das daraus entnehmbare Fußstück ist über einen Polygonring am Kugelkopf des Druckkolbens gehalten. Als nachteilig wird die relativ geringe axiale Fixierkraft angesehen, d. h. es besteht die Gefahr, dass der Kugelkopf aus dem Fußstück, bspw. während eines Handlings, einer Montage oder im Betrieb, rutscht. Des Weiteren offenbart die DE 35 41 198 A1 ein Winkelgelenk, dessen Fußstück über einen Käfig gelenkig an den Druckkolben angebunden ist. Diese Gestaltung erweist sich in Großserie als relativ kostenaufwändig. Such an angle joint is apparent from DE 10 2008 048 515 A1. The removable foot piece is held by a polygonal ring on the ball head of the pressure piston. As a disadvantage, the relatively low axial fixing force is considered, d. H. There is a risk that the ball head from the foot, for example. During a handling, assembly or in operation, slips. Furthermore, DE 35 41 198 A1 discloses an angle joint, the foot piece is connected via a cage articulated to the pressure piston. This design proves to be relatively expensive in mass production.
Zudem wird noch auf die DE 33 04 398 C2 verwiesen. In addition, reference is made to DE 33 04 398 C2.
Es ist Aufgabe der vorliegenden Erfindung, ein Winkelgelenk der eingangs genannten Art zu schaffen, bei dem die aufgezeigten Nachteile beseitigt sind. Insbesondere soll eine kostengünstige sowie sichere axiale Halterung der Gelenkpfanne am Kugelkopf geschaffen werden. It is an object of the present invention to provide an angle joint of the type mentioned, in which the disadvantages are eliminated. In particular, a cost-effective and secure axial retention of the socket on the ball head is to be created.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass als Ringelement ein dünnwandiger Schussdraht / Draht appliziert ist, der schleifenartig in der Ringnut sitzt, wobei die Ringnut axial oberhalb einer Kugelhalbierenden des Kugelkopfes verläuft. According to the invention, this object is achieved in that a thin-walled weft wire / wire is applied as a ring element, which sits like a loop in the annular groove, wherein the annular groove extends axially above a ball bisector of the ball head.
Somit liegt ein Winkelgelenk ohne die vorbeschriebenen Nachteile vor. Die vor- geschlagene Verbindung ist preiswert darstellbar. Eine automatisierte Montage lässt sich recht simpel bewerkstelligen. Der dünnwandige Draht soll bevorzugt, jedoch nicht ausschließlich, mit einer Drahtschussvorrichtung eingebracht werden. Das Führungsstück kann entweder als Druckkolben einer in den hebelartigen Nockenfolger eingebauten hydraulischen Spielausgleichsvorrichtung oder als rein„mechanische" Komponente wie ein in die Bohrung des Nockenfolgers eingebauter Ansatz (Einsteckelement) bzw. wie eine Spieleinstellschraube vorliegen. Ggf. kann das Führungsstück auch einteilig vom Nockenfolger abste- hen. Thus, there is an angle joint without the disadvantages described above. The proposed connection can be displayed inexpensively. An automated assembly can be done quite simply. The thin-walled wire should preferably, but not exclusively, be introduced with a wire-weft device. The guide piece can be present either as a pressure piston of a hydraulic lash adjuster built into the lever-type cam follower or as a purely "mechanical" component such as a lug (insert element) or as a lash adjuster screw - hen.
Die Ringnut für den Draht kann am Außenmantel des Kugelkopfes oder in der Gelenkpfanne des Fußstücks verlaufen. Bei erstgenannter Variante ist es erforderlich, dass ein oberer Kragen der Gelenkpfanne radial nach innen ragt. Zur Herstellung der Ringnut in der Gelenkpfanne bietet sich bspw. ein Scheibenfräser an. The annular groove for the wire may extend on the outer surface of the ball head or in the socket of the foot piece. In the first-mentioned variant, it is necessary for an upper collar of the socket to project radially inwards. To produce the annular groove in the socket, for example, offers a side milling cutter.
Zur einfachen Montier- und ggf. Demontierbarkeit des Ringelements hat das Fußstück gemäß einem weiteren Unteranspruch ein Fenster, in welches Endstücke des schleifenartig verlaufenden Ringelements einragen. Um das Ringelement in der Ringnut zu sichern, sollen die vorgenannten Endstücke in Umfangsrichtung voneinander weggebogen verlaufen. Sie sitzen bevorzugt an Seitenwänden des Fensters. Das vorgeschlagene Winkelgelenk kann auch außerhalb des Ventiltriebsbaus Anwendung finden. For easy mounting and, if necessary, disassembly of the ring element, the foot piece according to a further subclaim has a window into which protrude end pieces of the loop-like ring element. In order to secure the ring element in the annular groove, the aforementioned end pieces are intended to be bent away from each other in the circumferential direction. They preferably sit on side walls of the window. The proposed angle joint can also find application outside of the valve train.

In dieses ragen Endstücke 12 des Ringelements 10 ein. Die Endstücke 12 sind, wie Fig. 3 offenbart, leicht voneinander weggebogen, so dass das Ringelement 10 in der Ringnut 9 ausdrehsicher gehalten ist. Die Endstücke 12 liegen jeweils mit ihrer Außenseite an einem Kantenbereich von Seitenwänden 13 des Fensters 1 1 an. A ball joint 2 of a pressure piston 3 (guide piece) is pivotably connected to a joint pan 6 of a foot piece 7 in FIGS. In this case, the pressure piston 3 is axially slightly movable in a bore 14 of a lever-like cam follower 4 of a valve gear of an internal combustion engine and part of a play compensation element 5. The foot 7 has a pressure piston remote contact surface 8 for a gas exchange valve contact. In an annular groove 9 of the socket 6, a radially projecting annular element 10 is shown, via which the foot piece 7 is held axially positively on the ball head 2. It can be seen that the annular groove 9 extends axially above a ball bisector of the ball head 2. As a ring element 10, a thin-walled weft wire is applied, which, as can be seen from FIG. 3, sits like a loop in the annular groove 9. The foot 7 has a window 11. In this project end pieces 12 of the ring member 10 a. The end pieces 12 are, as shown in FIG. 3, slightly bent away from each other, so that the ring member 10 is held ausdrehsicher in the annular groove 9. The end pieces 12 abut each with its outer side at an edge region of side walls 13 of the window 1 1.
Anstelle des als Schussdraht ausgebildeten Ringelements 10 können auch zwei sich bogensehnenartig gegenüberliegende Stifte appliziert sein, die in respektive Nuten im Gelenkspalt eingreifen. Instead of the trained as a weft wire ring member 10 and two bow string-like opposing pins can be applied, which engage in respective grooves in the joint gap.
