Abstract
The invention relates to a hydrodynamic mechanical compound transmission comprising a transmission input shaft (E), a transmission output shaft (A), a hydrodynamic transmission part (2) and a mechanical transmission part (4). Said mechanical transmission part (4) comprises at least one speed/torque conversion device (5). The output of the mechanical speed/torque converter (5) is at least indirectly drive-connected to the transmission output shaft (1). According to the invention, the hydrodynamic retarder (25) which comprises a stator (26) and a rotor blade wheel (27) is spatially integrated in the transmission housing (11). In addition, the rotor blade wheel (27) of the hydrodynamic retarder (25) is at least indirectly coupled to the output shaft (A) of the mechanical speed/torque converter (5). The hydrodynamic retarder (25) functions as a secondary retarder, however, it is spatially arranged in the transmission before the downstream stage (6).
