Patent WO-0236287-A1 (WO)
Inventor: SCHWAGER ARIBERT
IPC: B21J5/12
Filed: 2001-11-01
Abstract: The invention relates to a method and device for the production of a workpiece with internal toothing, in particular a hollow wheel, by using a cup-shaped preform (N), with an essentially cylindrical side wall (N1) and a drift (5), with an outer profile corresponding to the internal toothing to be produced and a moulding tool which reduces the outer diameter of the cylindrical sidewall during a feed motion, whereby material from the cylinder wall region flows into the outer profile (6) of the drift (5). According to the invention, the moulding tool is in the form of a drawing die (14) which guarantees a stretch forming of the cylinder wall region (N1) and that two tool elements, producing an axial pressure in the cylinder wall region (N1) of the preform, engage with the preform during the stretch forming. A reduction in the outer diameter by stretch forming using a drawing die occurs in the method, whereby additional axial pressure is brought to bear on the cylindrical sidewall of the preform during the stretch forming.

Title: Verfahren, steuerungsgerät und computer-programm zur detektion fehlerhafter drucksensoren bei einer brennkraftmaschine
Inventor: MONINGER THOMAS
IPC: G01M99/00
Filed: 2003-05-27
Abstract: Die Erfindung betrifft ein Verfahren, ein Steuerungsgerät (200) und ein Computer-Programm zur Detektion eines fehlerhaften Saugrohrdrucksensors (220) und/oder eines fehlerhaften Umgebungsdrucksensors (210) bei einer Brennkraftmaschine (100). Aus dem Stand der Technik sind bereits Diagnoseverfahren und Geräte zur Erkennung der Fehlerhaftigkeit von Saugrohrdrucksensoren bekannt, allerdings nur bei konventionellen Brennkraftmaschinen, bei denen die Laststeuerung über die Drosselklappe (122) erfolgt, nicht jedoch für Brennkraftmaschinen (100), bei denen die Laststeuerung über eine Ventilsteuerung erfolgt. Ausgehend von diesem Stand der Technik ist es deshalb die Aufgabe der Erfindung, ein bekanntes Verfahren, ein bekanntes Steuerungsgerät (200) und ein bekanntes Computerprogramm zur Detektion eines fehlerhaften Saugrohrdrucksensors (220) und/oder eines fehlerhaften Umgebungsdrucksensors (210) bei einer konventionellen Brennkraftmaschine (100) derart weiterzubilden, dass diese Detektion auch bei Brennkraftmaschinen (100) mit Ventilsteuerung möglich ist. Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die gewünschte Detektion ausschliesslich aufgrund einer direkten Auswertung des Druckes vor der Drosselklappe (122) und des Druckes im Saugrohr (120) erfolgt. Eine Ableitung von Lastsignalen aus diesen Drücken, wie sie im Stand der Technik erforderlich ist, wird damit vorteilhafterweise, zumindest für die Detektion, ob mindestens einer der Drucksensoren fehlerhaft ist, entbehrlich (Fig. 1).
