The invention relates to an automatic gearbox, especially for a motor vehicle, comprising a drive shaft (7), a driven shaft which is non-coaxially arranged on the drive shaft (7), a planetary gearbox which is non coaxial in relation to the drive shaft (7), a planetary gear which is coaxial in relation to the drive shaft (7) and which comprises at least one set of planet wheels (14) and at least one switch element (10) for the selective transmission of the speed of a driving motor of the drive shaft (7) on an output element of the planet gear. The automatic gearbox also comprises a chain drive (18) with constant transmission, whose drive wheel (19) is connected to the output element of the planetary gear and is coaxially arranged on the drive shaft (7), and whose driven wheel (22) is actively connected to the driven shaft by means of a constant transmission. The chain drive (18) is adjacent to the housing wall (2) of the automatic gearbox directly in the axial direction thereof. The drive wheel (19) of the chain drive (18) at least partially engages with a switch element (10) in an axial manner on the side thereof which faces away from the gearbox housing wall (2).

An automatic transmission for a motor vehicle, comprising one drive shaft (7), one driven shaft on an axis different than the drive shaft (7), one planetary gear co-axial to the drive shaft (7) and having at least one planetary gear set (14) and at least one switch element (10) for selective transmission of an input rotational speed of the drive shaft (7) to an output element of the planetary gear and one chain drive (18) of constant ratio abutting in an axial direction directly on a transmission housing wall (2) and whose drive wheel (19) is connected with the output element of the planetary gear and situated co-axially to the drive shaft (7) and whose driven wheel (22) is operatively connected with a driven shaft via a constant ratio, the drive wheel (19) of the chain drive (18) radially overlaps at least partly, in the axial direction, the switch element (10) axially directly abutting on a side thereof remote from the transmission housing wall (2).
