Abstract: A two-stage clutch for separable connection of an input shaft to at least one output shaft, having a clutch cover, a clutch basket and a plurality of partial clutches, the partial clutches being operated in series. A first partial clutch is a pilot clutch, which is actively operable. A second partial clutch is a main clutch, which is operable by the pilot clutch, an operating force for the main clutch being produced by a torque transmitted by a shaft. In this two-stage clutch, the clutch cover is firmly connectible to the clutch basket. With the two-stage clutch proposed here, high torques can be transmitted despite small external operating forces. At the same time, the construction and assembly are greatly simplified in spite of the considerable complexity of the two-stage clutch, and the two-stage clutch has a significantly reduced rotating mass.
