Abstract

Vorgeschlagen ist ein schaltbarer Schlepphebel (1) mit einem Außen- und einem Innenhebel (2, 4). Im Innenhebel (4) verläuft ein längs nach außen verlagerbares Koppelmittel (5). Dieses kann zum Koppelzweck unter einer Mitnehmerfläche (14) eines Querbalkens (15) des Außenhebels (2) verlagert werden. Um die Fertigungskosten zu senken, ist ein Außenmantel (16) des Koppelmittels (5) und eine Durchgangsbohrung (13) im Innenhebel (4) für das Koppelmittel (5) komplett glattflächig gefertigt. Dabei soll der Außenmantel (16) des Koppelmittels (5) in einem Spitzenlos-Schleifverfahren feinbearbeitet werden.
