Abstract

A multi-gear transmission of a vehicle having a housing in which four planetary gearsets and a plurality of shafts and shifting elements are arranged. The drive input shaft can couple the sun gears of gearsets (RS1, RS3) and the carrier of gearset (RS1) and can be connected indirectly to the carrier of gearset (RS2). The drive output shaft couples the ring gear of gearset (RS4) and is connected directly or can be indirectly connected to the carrier of gearset (RS3), the sun gear and carrier of gearset (RS1) and the sun gear of gearset (RS4) can be connected to the housing. The ring gear of gearset (RS1) couples the carrier of gearset (RS4) and can be or is connected to the sun gear of gearset (RS2), and the ring gear of gearset (RS2) and the ring gear of gearset (RS3) are, or can be, connected to one another.
