Abstract
Die Erfindung betrifft einen Aktuator, bestehend aus einem hydraulischen bzw. pneumatischen Antrieb, der erfindungsgemäß mit einem elektromechanischen Antrieb in einer Baueinheit kombiniert ist, wobei der hydraulische bzw. pneumatische Antrieb der Regelantrieb des Aktuators ist und wobei der elektromechanische Antrieb der Alternativbetätigung des Aktuators dient.The invention relates to an actuator, consisting of a hydraulic or pneumatic drive, which is combined according to the invention with an electromechanical drive in a structural unit, wherein the hydraulic or pneumatic drive is the variable speed drive of the actuator and wherein the electromechanical drive of the actuator serves the alternative operation.
Description
Die Erfindung betrifft einen Aktuator, der aus einem hydraulischen oder pneumatischen Antrieb besteht. Aktuatoren, die in Flugzeugsystemen Anwendung finden, müssen besonderen Sicherheitsstandards genügen. Um die Funktionsfähigkeit des Flugzeugsystems aufrecht zu erhalten, werden bei herkömmlichen Systemen, in denen die Aktuatoren durch hydraulische bzw. pneumatische Antriebe betätigt werden, für eine Alternativbetätigung bei Ausfall des Erstsystems parallele zweite Hydraulik- bzw. Pneumatiksysteme zur Betätigung der Aktuatoren vorgesehen. Das Vorsehen eines zweiten Hydraulik- bzw. Pneumatiksystems für jeden Aktuator ist aufwendig und teuer. Darüber hinaus sind diese Antriebe auch schwer, was insbesondere bei der Verwendung als Bauteil eines Flugzeugsystems nachteilig ist. Darüber hinaus kann es auch bei Verwendung von zwei parallelen Hydraulik- bzw. Pneumatiksystemen zu einem funktionalen Totalverlust der Aktuatoreinheit kommen, wenn beispielsweise im Aktuator die Kolbendichtung defekt ist.The The invention relates to an actuator consisting of a hydraulic or pneumatic drive exists. Actuators operating in aircraft systems Find application meet special safety standards. To the functionality of the aircraft system are maintained at conventional Systems in which the actuators by hydraulic or pneumatic Actuators actuated be, for an alternative operation in case of failure of the first system parallel second hydraulic or pneumatic systems for operation provided the actuators. The provision of a second hydraulic or Pneumatic system for every actuator is complex and expensive. In addition, these are drives also difficult, especially when used as a component of a Aircraft system is disadvantageous. In addition, it can also be at Use of two parallel hydraulic or pneumatic systems come to a functional loss of the actuator unit, if For example, in the actuator, the piston seal is defective.
Aufgabe der vorliegenden Erfindung ist es daher, einen Aktuator mit verbesserter Funktionssicherheit bereitzustellen, der kompakter und damit leichter aufgebaut ist.task It is therefore an object of the present invention to provide an improved actuator To provide functional reliability that is more compact and therefore lighter is constructed.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Hier ist bei einem Aktuator, der aus einem hydraulischen bzw. pneumatischen Antrieb besteht und als Alternativantrieb ein elektromechanischer Antrieb in einer Baueinheit kombiniert, wobei der hydraulische bzw. pneumatische Antrieb der Regelantrieb des Aktuators ist und wobei der elektromechanische Antrieb der Alternativbetätigung des Aktuators dient. Diese Alternativbetätigung kommt nur dann zum Tragen, wenn der hydraulische bzw. pneumatische Erstantrieb ausfällt. Durch die Integration des hydraulischen bzw. pneumatischen Antriebs einerseits mit dem elektromechanischen Antrieb andererseits in einer Baueinheit, d. h. in einem Gerät, wird eine besonders kompakte und leicht bauende Aktuatoreinheit geschaffen, die sich insbesondere zum Einsatz in Flugsteuerungssystemen eignet. Aus den Unteransprüchen ergeben sich vorteilhafte Ausgestaltungen der Erfindung.According to the invention this Problem solved by the features of claim 1. Here is an actuator, which consists of a hydraulic or pneumatic drive and as an alternative drive an electromechanical drive in a structural unit combined, wherein the hydraulic or pneumatic drive of the Is the actuator of the actuator and wherein the electromechanical Drive the alternative operation of the actuator is used. This alternative operation comes into effect only if the hydraulic or pneumatic first drive fails. By the integration of the hydraulic or pneumatic drive on the one hand with the electromechanical drive on the other hand in a structural unit, d. H. in a device, becomes a particularly compact and easy-to-build actuator unit created especially for use in flight control systems suitable. From the dependent claims arise advantageous embodiments of the invention.
Demnach kann der elektromechanische Antrieb seriell zum hydraulischen oder pneumatischen Antrieb angeordnet sein. Alternativ hierzu kann der elektromechanische Antrieb parallel zum hydraulischen oder pneumatischen Antrieb angeordnet sein.Therefore the electromechanical drive can be serial to hydraulic or be arranged pneumatic drive. Alternatively, the electromechanical Drive arranged parallel to the hydraulic or pneumatic drive be.
Der elektromechanische Antrieb kann lose mit dem hydraulischen oder pneumatischen Antrieb verbunden sein, wobei er im Normalbetrieb keine Bewegung ausführt und nur für die Alternativbewegung ansteuerbar ist. Andererseits kann der elektromechanische Antrieb fest mit dem hydraulischen oder pneumatischen Antrieb verbunden sein, wobei er im Normalbetrieb lastlos, d. h. passiv, die Bewegung des hydraulischen oder pneumatischen Antriebs ausführt und nur für die Alternativbewegung als aktiver Antrieb ansteuerbar ist.Of the electromechanical drive can be loose with the hydraulic or be connected to pneumatic drive, where he is in normal operation does not do any movement and only for the alternative movement is controllable. On the other hand, the electromechanical Drive firmly connected to the hydraulic or pneumatic drive be, whereby he in normal operation without a load, d. H. passive, the movement of the hydraulic or pneumatic drive and performs only for the alternative movement can be controlled as an active drive.
