Abstract
Official abstract text for this publication.
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 (RS 1 , RS 3 ) and the carrier of gearset (RS 1 ) and can be connected indirectly to the carrier of gearset (RS 2 ). The drive output shaft couples the ring gear of gearset (RS 4 ) and is connected directly or can be indirectly connected to the carrier of gearset (RS 3 ), the sun gear and carrier of gearset (RS 1 ) and the sun gear of gearset (RS 4 ) can be connected to the housing. The ring gear of gearset (RS 1 ) couples the carrier of gearset (RS 4 ) and can be or is connected to the sun gear of gearset (RS 2 ), and the ring gear of gearset (RS 2 ) and the ring gear of gearset (RS 3 ) are, or can be, connected to one another.
First claim
