Hydrodynamic-mechanical multi-speed compound transmission, especially a six-speed torque-converter transmission |
摘要 |
The invention related to a hydrodynamic-mechanical multi-speed compound transmission has at least four speeds. The transmission includes a transmission input shaft and a transmission output shaft as well as a hydrodynamic transmission part. The hydrodynamic and the mechanical transmission parts are connected in series when seen from the power flow direction. Mechanisms are provided for by-passing the hydrodynamic transmission part during power transmission. The hydrodynamic transmission part includes at least one hydrodynamic speed-torque converter. The mechanical transmission part includes a mechanical speed-torque converting device with at least two planetary gear sets. The mechanical transmission part is designed in such a way that transmission ratios in the individual gear steps cause gear step jumps of phi <=1.45 between two successive gear steps of the individual speeds.
