Abstract:

The present invention relates to a torque transmission device (2) comprising a planetary gear train (22), which has a rotatable component (28), a stationary housing (18), and a clutch device (32) for selective coupling of the component (28) with the stationary housing (18). The clutch device (32) has a friction-locking first clutch (34) and a positive-locking second clutch (36), wherein the component (28) may be coupled to the stationary housing (18) via the first clutch (34) before a coupling by means of the second clutch (36).
