Abstract

Die Erfindung betrifft eine hydraulische Steuerung für eine hydraulisch betätigbare Kupplungsbremskombination (13) insbesondere an der Exzenterwelle (12) einer mechanischen Presse mit einer eine Hydropumpe (35) und bevorzugt auch einen Hydrospeicher (36) aufweisenden Druckmittelquelle zur Versorgung eines die Kupplung und/oder die Bremse betätigenden Hydrozylinders (18) mit Druckmittel. Eine bekannte Steuerung dieser Art weist eine Sicherheitsventilanordnung (48,49), die einen Zulaufanschluß aufweist, über den ein Strömungspfad von der Druckmittelquelle zum Hydrozylinder führt, und ein proportional verstellbaren Regelventil (40,70) auf, mit dem der den Hydrozylinder (18) beaufschlagende Druck einstellbar ist.The invention relates to a hydraulic control for a hydraulically operated Clutch brake combination (13) in particular on the eccentric shaft (12) of a mechanical Press with a hydraulic pump (35) and preferably also a hydraulic accumulator (36) having pressure medium source for supplying a clutch and / or the hydraulic cylinder (18) actuating the brake with pressure medium. A well-known control This type has a safety valve arrangement (48, 49) which has an inlet connection has, via which a flow path from the pressure medium source to the hydraulic cylinder leads, and a proportionally adjustable control valve (40,70) with which the hydraulic cylinder (18) pressurizing pressure is adjustable.

Ziel der Erfindung ist es, die bekannte hydraulische Steuerung so weiterzuentwikkeln, daß sie eine hohe Dynamik besitzt und damit kurze Druckaufbau- und Druckabbauzeiten und eine hohe Regelgüte ermöglicht.The aim of the invention is to further develop the known hydraulic control so that it has a high dynamic and thus short pressure build-up and Pressure reduction times and a high control quality enables.

Dies wird dadurch erreicht daß ein elektrischer Drucksensor (60) vorhanden ist, von dem der den Hydrozylinder (18) beaufschlagende Druck erfaßbar ist, daß eine Regelelektronik (61) vorhanden ist, dem ein dem erfaßten Druck entsprechendes elektrisches Signal des Drucksensors zugeführt wird und daß das Regelventil ein elektrisch ansteuerbares Proportional-Wegeventil ist, das von der Regelelektronik entsprechend dem erfaßten Ist-Druck und dem gewünschten Soll-Druck angesteuert wird.

Figure 00000001
This is achieved in that an electrical pressure sensor (60) is present, from which the pressure acting on the hydraulic cylinder (18) can be detected, that control electronics (61) are available, to which an electrical signal corresponding to the detected pressure of the pressure sensor is supplied, and in that the control valve is an electrically controllable proportional directional control valve which is controlled by the control electronics in accordance with the detected actual pressure and the desired set pressure.
