More Information
Summary:The invention relates to a torque-transmitting device (10, 20, 30), to a drive system having a torque-transmitting device (10, 20, 30), and to a motor vehicle, wherein the torque-transmitting device (10, 20, 30) has a first input shaft (EW1), a second input shaft (EW2), a Ravigneaux planetary gearset (PGS1 and PGS2), a further gearset (WG), two separating clutches (C1, C2), two brake devices (B1,B2), and an output shaft (AW). The further gearset (WG) has an input side and an output side, wherein the input side is rotationally connected to the input shaft (EW1) and the output side can be rotationally connected to the first sun gear (S1) of the Ravigneaux planetary gearset (PGS1 and PGS2) by means of the second separating clutch (C2). The first separating clutch (C1) is designed to rotationally connect the first input shaft (EW1) to the planet carrier (PT) of the Ravigneaux planetary gearset (PGS1 and PGS2), the first brake device (B1) is designed to releasably fix the second sun gear (S2) of the Ravigneaux planetary gearset (PGS1 and PGS2), the second brake device (B2) is designed to releasably fix the planet carrier (PT), and the output shaft (AW) is rotationally connected to thesecond ring gear of the Ravigneaux planetary gearset (PGS1 and PGS2).
