Abstract

Es wird ein kolbenstangenloser Linearantrieb vorgeschlagen, der ein einen Längsschlitz (14) aufweisendes Gehäuse und ein in dem Gehäuse längsbeweglich angeordnetes Antriebsteil (7) aufweist. Ein mit dem Antriebsteil (7) verbundenes Übertragungsglied ragt durch den Längsschlitz (14) hindurch nach außen. Im Bereich der beiden Schlitzflanken des Längsschlitzes (14) ist jeweils ein sich in Schlitzlängsrichtung erstreckender gehäusefester Widerstandsstreifen (23, 23') angeordnet. An dem Übertragungsglied ist eine Schleifkontaktanordnung (32) vorgesehen, die gleichzeitig mit beiden Widerstandsstreifen (23, 23') in Kontakt steht und bei der Längsbewegung des Übertragungsgliedes auf den Widerstandsstreifen (23, 23') entlang gleitet. Vorgesehene Anschlußmittel (28) ermöglichen die Verbindung der beiden Wiederstandsstreifen (23, 23') mit einer Positionserfassungs-Auswerteeinrichtung.
