Abstract

A transmission for a motor vehicle includes a first planetary gear set with at least three central gears which are formed by a ring gear and two sun gears or by two ring gears and one sun gear. A second planetary gear set includes two central gears which are formed by one ring gear and one sun gear. One of the central gears of the second planetary gear set is constantly connected in a torque-proof manner to one of the central gears of the first planetary gear set. The one of the central gears of the first planetary gear set differs from and is arranged in a common gear set plane with the one of the central gears of the second planetary gear set. A carrier of the first planetary gear set is constantly connected in a torque-proof manner to a carrier of the second planetary gear set.
