Abstract
An auxiliary transmission (31)with controllable clutch (2) is described for the optional distribution of a drive output torque to one or more drive output shafts with a reduction gear stage (3) and with a hydraulic pump (14). The hydraulic pump (14) is arranged on a transmission input shaft (4) and the reduction gear stage (3) is connected in series in such manner that the drive input power to the hydraulic pump (14) remains at least approximately the same when a range change takes place in the reduction gear stage (3).
