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).
