Abstract
The invention relates to an automatic gearbox, especially for a motor vehicle, comprising a drive shaft (), a driven shaft which is non-coaxially arranged on the drive shaft (), a planetary gearbox which is non coaxial in relation to the drive shaft (), a planetary gear which is coaxial in relation to the drive shaft () and which comprises at least one set of planet wheels () and at least one switch element () for the selective transmission of the speed of a driving motor of the drive shaft () on an output element of the planet gear. The automatic gearbox also comprises a chain drive () with constant transmission, whose drive wheel () is connected to the output element of the planetary gear and is coaxially arranged on the drive shaft (), and whose driven wheel () is actively connected to the driven shaft by means of a constant transmission. The chain drive () is adjacent to the housing wall () of the automatic gearbox directly in the axial direction thereof. The drive wheel () of the chain drive () at least partially engages with a switch element () in an axial manner on the side thereof which faces away from the gearbox housing wall ().
