Abstract

Der Kraftschrauber weist ein drehmomentabhängig betätigtes Schaltgetriebe (4) mit zwei Antriebszweigen mit unterschiedlichem Übersetzungsverhältnis auf. Die Zu- oder Abschaltung der beiden Antriebszweige erfolgt durch zwei Kupplungen (32,48), von denen je eine in einem Antriebszweig angeordnet ist. Beide Kupplungen weisen ein gemeinsames bewegbares Kupplungsteil (36) auf, welches derart vorgespannt ist, daß immer eine der beiden Kupplungen in Eingriff und die andere Kupplung außer Eingriff ist. Zur Erzielung einer kompakten Bauform werden in dem Schaltgetriebe (4) Planetengetriebe (21,26) verwendet.
