Abstract

The electric muscle is uniformly designed and primarily made of modules (1), which are connected to each other by pivoting axes (3). In the modules (1), (electro-) magnets are present that create a pivoting of the axes (3) by attracting one side and repelling the other side. Said drive has high acceleration if all modules (1) are actuated at the same time. The invention also relates to an electric substitute for hydraulic cylinders and has remarkable advantages compared to said cylinders.

Description

Beschreibungdescription

Die Erfindung betrifft ein mechanisches Gewebe, das sich mit einer dynamischen Bewegung kontrahieren sowie ausdehnen kann Durch die Verbindung beliebig vieler Module (1 ) die in Serie geschalten werden, kann der Kraftweg je nach Anwendung gewählt werden Die Hohe des Antriebs ist somit hauptsächlich von der Anzahl der in Serie geschalteten Module (1 ) abhangig Die Kraft entsteht durch Interaktionen magnetischer Felder die durch Elektromagnete bzw Permanentmagnete induziert werden Die Abmessungen in den Abbildungen sind so gewählt, dass bei einem Ausgangswinkel der Achsen (3) um 90 Grad der Kraftweg bei ca 50% liegt Um eine Kontraktion beziehungsweise Ausdehnung zu erreichen, kann die Schaltung so gewählt werden, dass bei den aneinander gereihten Modulen (1 ) abwechslungsweise beim Kraftubertragenden (5) und beim nächsten Modul (1) bei den beiden Elektromagneten von den Modulen (1) die Stromπchtung gewechselt wird So können für die Magnete die nicht geschaltet werden müssen auch Permanentmagnete verwendet werden Die Stromzufuhr für die Elektromagnete kann durch flexible Stromkabel realisiert werden Bei Bewegungen nahe am kontrahierten Zustand können die seitlichen Magnetfelder der Module (1 ) mit denen der Nachbarmodule interagieren Falls die geringe seitliche Feldstarke eines (Elektro-) Magnets brauchbar gemacht werden kann, wurde die zum Kraftweg lineare wirkende Kraft zwischen den Modulen (1) bei Bewegungen nahe am kontrahierten Zustand die Kraftverminderung durch die kleinen Achsenwinkel teilweise kompensierenThe invention relates to a mechanical fabric that can contract and expand with a dynamic movement By connecting any number of modules (1) are connected in series, the force can be chosen depending on the application The height of the drive is thus mainly on the number The force produced by interactions of magnetic fields which are induced by electromagnets or permanent magnets The dimensions in the figures are chosen so that at an initial angle of the axes (3) by 90 degrees of the force path at about 50% In order to achieve a contraction or expansion, the circuit can be chosen so that in the juxtaposed modules (1) alternately at Kraftubertragenden (5) and the next module (1) in the two electromagnets of the modules (1) Stromπchtung So you can not have to switch for the magnets also Permanent magnets can be used Power supply for the electromagnets can be realized by flexible power cables In movements close to the contracted state, the lateral magnetic fields of the modules (1) can interact with those of the neighboring modules If the low lateral field strength of an (electric) magnet can be made useful, In the case of movements close to the contracted state, the force acting linearly between the modules (1) and the force path was partially compensated for the force reduction by the small axis angles

Der Elektromuskel ist vor allem als elektrischer Ersatz für Hydraulikzylinder gedacht und weist gegenüber diesem beachtliche Vorteile auf Gegenüber herkömmlichen Elektrolinearantπeben hat der Elektromuskel den Vorteil, dass keine parasitären Kräfte senkrecht zur Bewegungsπchtung bestehen Der Elektromuskel eine hohe Besch'eumgung wenn sich in jedem Modul (1) gleichzeitig die Kraftubertragenden (Elektro-) Magnete (6) von der einen Seite zur anderen bewegen Dank dem dass dieser Antrieb einheitlich aufgebaut ist und nur aus 6 verschiedenen Einzelteilen besteht, ist die Konstruktion zu den schon bestehenden Linearantrieben oder Elektrozylindern relativ simpel aufgebaut. So ermöglicht der einheitliche Aufbau auch kleine Ausführungen des Elektromuskels.The electric muscle is primarily intended as an electrical substitute for hydraulic cylinders and has considerable advantages over conventional electrolinearning the electric muscle has the advantage that there are no parasitic forces perpendicular to the movement of the electric muscle. at the same time move the force-transmitting (electric) magnets (6) from one side to the other thanks to the fact that this drive is built up uniformly and consists of only 6 different parts, the construction of the already existing linear drives or electric cylinders is relatively simple.
