Abstract (en)
[origin: WO2017067777A1] The invention relates to a planetary power-shift multi-stage transmission, in particular for an internal combustion engine and/or electric motor drive of a motor vehicle, comprising multiple forward gears and a reverse gear and having a drive shaft (1) as a first shaft; an output shaft (2) as a second shaft; two planetary gear sets (RS1, RS2) which are coupled together or can be coupled together and each of which has at least one first transmission element (1.1, 2.1), a second transmission element (1.2, 2.2), and a third transmission element (1.3, 2.3); and multiple shifting elements (10, 20, 30, 40, 50, 60, 70) which are paired with the planetary gear sets (RS1, RS2) and the selective shifting of which produces a transmission ratio between the drive shaft (1) and the output shaft (2) for the respective gear stage. At least three of the shifting elements (10, 20, 30, 40, 50, 60, 70) are designed as brakes, by means of which the first transmission element (1.1, 2.1), the second transmission element (1.2, 2.2), or the third transmission element (1.3, 2.3) of the planetary gear sets (RS1, RS2) can be braked directly or indirectly against a component (G) fixed to the housing. Additionally or alternatively thereto, at least two of the shifting elements (10, 20, 30, 40, 50, 60, 70) are designed as formfitting shifting elements, in particular claw shifting elements.
