Abstract

Beschrieben wird eine Fügeverbindnung zwischen zwei Fügepartnern, die jeweils wenigstens einen ebenen, zylindrischen oder konischen Flächenabschnitt aufweisen, über den die Fügepartner kraftbeaufschlagt und aufeinander gleitend derart in Berührung bringbar sind, daß sich die ebenen, zylindrischen oder konischen Flächenabschnitte beider Fügepartner nur teilweise überlappen und im Berührungsbereich eine gemeinsame Auflagefläche bilden.
Die Erfindung zeichnet sich dadurch aus, daß die ebenen, zylindrischen oder konischen Flächenabschnitte der Fügepartner jeweils durch wenigstens einen Hinterstich einseitig begrenzt sind, und daß die Fügepartner derart in Verbindung bringbar sind, daß die gemeinsame Auflagefläche der Fügepartner in einer Richtung durch den Hinterstich des einen Fügepartners und in entgegengesetzter Richtung durch den Hinterstich des anderen Fügepartners begrenzt ist.
