ABSTRACT:
An arrangement of two adjacent planetary gearsets (1, 2) in a housing of a transmission of a vehicle. In the arrangement a ring gear carrier (3) is connected to ring gear (19) of the first planetary gearset (1) and a sun gear (8) of the second planetary gearset (2), which is connected to a shaft (5) of the transmission, such that torque is transferred between the ring gear (19) of the first planetary gearset (1) and the shaft of the transmission (5). The ring gear carrier (3) is therefore engaged both with the shaft (5) of the transmission and with the sun gear (8) of the second planetary gearset (2).
