Abstract
Mechanischer Ventilstößel (10) bestehend aus einer Lastverteilerplatte (20) und einem tassenförmigen Stößelkörper (12) mit einem Boden (14), wobei die Lastverteilerplatte (20) auf der Innenseite des Bodens (14) des Stößelkörpers (12) anliegt und mit diesem fest verbunden ist und wobei die Lastverteilerplatte (20) und der Stößelkörper (12) ein Tiefziehteil aus Blech sind.Mechanical valve tappet (10) consisting of a load distributor plate (20) and a cup-shaped tappet body (12) with a base (14), the load distributor plate (20) resting on the inside of the base (14) of the tappet body (12) and being fixed with it is connected and wherein the load distribution plate (20) and the tappet body (12) are a deep-drawn part made of sheet metal.
Description
Die Erfindung betrifft einen mechanischen Ventilstößel.The invention relates to a mechanical valve lifter.
Ein mechanischer Ventilstößel wird dazu verwendet, die Rotationsbewegung eines Nockens einer Nockenwelle in eine translatorische Verstellung eines Ventils eines Verbrennungsmotors umzusetzen. Im Gegensatz zu einem hydraulischen Ventilstößel, in den beispielsweise ein hydraulischer Ventilspielausgleich integriert sein kann, ist ein mechanischer Ventilstößel vergleichsweise einfach aufgebaut und gibt die vom Nocken vorgegebene Bewegung auf mechanisch direktem Weg an das Ventil weiter.A mechanical valve lifter is used to convert the rotational movement of a cam of a camshaft into a translational adjustment of a valve of an internal combustion engine. In contrast to a hydraulic valve lifter, in which, for example, a hydraulic valve clearance compensation can be integrated, a mechanical valve lifter is comparatively simple and gives the cam predetermined movement on a mechanically direct path to the valve on.
Aus dem Stand der Technik sind verschiedene Konstruktionen für einen solchen Ventilstößel bekannt. Die

Die Aufgabe der Erfindung besteht darin, einen Ventilstößel zu schaffen, der mit besonders geringen Kosten hergestellt werden kann.The object of the invention is to provide a valve tappet which can be manufactured at a particularly low cost.
Zu diesem Zweck ist erfindungsgemäß ein mechanischer Ventilstößel vorgesehen, bestehend aus einer Lastverteilerplatte und einem tassenförmigen Stößelkörper mit einem Baden, wobei die Lastverteilerplatte auf der Innenseite des Bodens des Stößelkörpers anliegt und mit diesem fest verbunden ist und wobei die Lastverteilerplatte und der Stößelkörper ein Tiefziehteil aus Blech sind. Die beiden Bauteile des Ventilstößels, also die Lastverteilerplatte und der Stößelkörper, können mit minimalem Aufwand aus Blech hergestellt werden und in einfacher Weise miteinander verbunden werden. Vorzugsweise wird hierfür eine simple Rastverbindung verwendet, die durch eine Einschnürung am Stößelkörper gebildet ist, hinter der die Lastverteilerplatte elastisch einrastet.For this purpose, a mechanical valve lifter according to the invention is provided, consisting of a load distribution plate and a cup-shaped plunger body with a bath, wherein the load distribution plate rests on the inside of the bottom of the plunger body and is firmly connected thereto and wherein the load distribution plate and the plunger body is a deep-drawn part of sheet metal are. The two components of the valve stem, so the load distribution plate and the plunger body can be made with minimal effort from sheet metal and connected together in a simple manner. Preferably, a simple latching connection is used for this purpose, which is formed by a constriction on the plunger body behind which the load distribution plate engages elastically.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention will become apparent from the dependent claims.
Die Erfindung wird nachfolgend anhand zweier bevorzugter Ausführungsformen beschrieben, die in den beigefügten Zeichnungen dargestellt sind. in diesen zeigen:The invention will be described below with reference to two preferred embodiments, which are illustrated in the accompanying drawings. in these show:
