Description
Ein bekannter Schwinghebel dieser Art besteht aus zwei zusammengeschweißten Wangen. Die Angriffspunkte der Steuerungs- und Lagerkräfte sind durch weitere eingeschweißte Stücke verstärkt. Der Schwinghebel hat an Stelle des sonst üblichen Auges für die Schwinghebelachse ein einseitig offenes Lager. Der bekannte Schwinghebel weist also außer den beiden Wangen noch drei weitere Stücke auf, die besonders angeschweißt werde müssen. Dadurch ist die Ausführung umständlich und kostspielig.A known rocker arm of this type consists of two welded together Cheeks. The points of application of the control and bearing forces are welded in through additional ones Reinforced pieces. The rocker arm has instead of the usual eye for the Rocker arm axis a bearing open on one side. The known rocker arm thus has in addition to the two cheeks, there are three other pieces that are specially welded on will have to. This makes it cumbersome and expensive to carry out.
Die Erfindung bezieht sich auf einen aus vorgeformten Wangen zusammengeschweißten Schwinghebel für die Steuerung von Ventilen, der insbesondere für schnell laufende Einspritzbrennkraftmaschinen verwendet wird.The invention relates to a welded together from preformed cheeks Rocker arm for the control of valves, especially for high-speed ones Injection internal combustion engines is used.
Der Schwinghebel gemäß der Erfindung kennzeichnet sich dadurch, daß in die Wangen nicht nur, wie an sich bei einstückigen Hebeln bekannt, Augen für die Lagerung auf der Schwinghebelachse und die Augen für die Übertragung der Steuerungsdrücke eingeformt, sondern auch an .den Wangenrändern-senkrecht zur Wangenebene Stege angeformt sind, die beim Aneinanderlegen der Wangen Stöße für das Zusammenschweißen bilden. Hierdurch ergeben sich einfache und billige Herstellung sowie besonders geringes Gewicht des Schwinghebels und damit nur kleine Massenkräfte in. der Steuerung. Die Schwinghebel sind daher für hohe Beanspruchungen und lange Betriebszeit besonders geeignet.The rocker arm according to the invention is characterized in that not only in the cheeks, as is known per se with one-piece levers, eyes for the storage on the rocker arm axis and the eyes for the transmission of the control pressures molded in, but also on .den cheek edges-perpendicular to the cheek plane webs formed that form buttocks for welding together when the cheeks are placed together. This results in simple and cheap production and particularly low production Weight of the rocker arm and thus only small inertia forces in the control. the Rocker arms are therefore particularly suitable for high loads and long operating times suitable.
Vorteilhaft sind an .einem z. B. aus zwei Wangen zusammengeschweißten Schwinghebel die Stege an dem einen Ende der Wangen verstärkt angeformt und dienen zur Übertragung. der Steuerungskräfte auf den Ventilschaft.Are advantageous to .einem z. B. welded together from two cheeks Rocker arm, the webs at one end of the cheeks are reinforced and are used for transmission. the control forces on the valve stem.
Zweckmäßig sind die Wangen parallel angeordnet. Die Zeichnung zeigt ein Ausführungsbeispiel gemäß der Erfindung für einen einseitigen, aus zwei vorgeformten Wangen zusammengeschweißten und bearbeiteten Schwinghebel, und zwar in Abb. i in Seitenansicht, Abb. 2 in Draufsicht und Abb. 3 im Schnitt nach Linie III-III der Abb. 2. i bzw. 2 sind die beiden geschmiedeten Wangen des Schwinghebels, die Augen 3 bzw. q. mit einer Bohrung zur Lagerung auf der Schwinghebelachse und Augen 5 bzw. 6 mit einer Bohrung zur Lagerung einer Nockenrolle aufweisen. An den Rändern der Wangen i bzw. 2 sind Stege 7 bzw. 8, 9 bzw. io und ii bzw. 12 angeschmiedet. Die Wangen i bzw. 2 sind an den Stößen der Stege 7, 8, 9, ro sowie 1i, 1.2 z. B. durch Schweißung 13 und 14 sowie 15 verbunden.The cheeks are expediently arranged in parallel. The drawing shows an embodiment according to the invention for a one-sided, preformed from two Cheeks welded together and machined rocker arm, namely in Fig. I in Side view, Fig. 2 in plan view and Fig. 3 in section along line III-III of Fig. 2. i and 2 are the two forged cheeks of the rocker arm, the eyes 3 or q. with a hole for mounting on the rocker arm axis and eyes 5 resp. 6 have a bore for mounting a cam roller. On the edges of the Cheeks i and 2 are bars 7 or 8, 9 or io and ii or 12 forged on. the Cheeks i and 2 are at the joints of the webs 7, 8, 9, ro and 1i, 1.2 z. B. by Weld 13 and 14 and 15 connected.
Das Ausführungsbeispiel zeigt weiterhin, daß es nach der Erfindung ohne weiteres möglich ist, jede Wange i und 2 beliebig, je nach den Raumverhältnissen zu gestalten. Bei dem dargestellten Schwinghebel z. B. ist das Auge 3 der Wange 2 breiter gehalten.The embodiment also shows that it is according to the invention Any cheek i and 2 is easily possible, depending on the space available to design. In the illustrated rocker arm z. B. is eye 3 of the cheek 2 held wider.
