Hydromechanical drive with a hydromotor and a mechanical variable speed transmission

The transmission has a mechanical multi-step variable speed transmission (11) attached to a drive shaft (4) of a hydraulic pump-driven hydraulic motor (1) of a hydrostatic continuously variable transmission. The speed transmission is shiftable by a gear shifting device (17), which is arranged directly adjacent to the motor and consolidated with the motor into a preassembled constructional unit. The shifting device is arranged in an area of an axial section of the drive shaft that projects from a drive shaft area, which is axially delimited by two drive shaft bearings (5, 6).
