METHOD FOR IMPROVING SHIFT QUALITY DURING GEAR SHIFTING AND GEAR SHIFTING CONTROL

摘要

The invention relates to a method for improving the shift quality during gear shifting in a gearbox unit (1), containing at least one gear branch for power transfer via a hydrodynamic clutch (2) which can be coupled in series with a mechanical gearing part containing means for realizing at least two speeds. The invention is characterized in that: during power transfer via the hydrodynamic clutch during a gear-shift operation between two mechanical speeds, the fill factor of the hydrodynamic clutch (2) is so altered that a variable which at least indirectly characterizes the rotational speed of the primary bucket wheel (4) of the hydrodynamic clutch (2) is held substantially constant over a certain range of the gear-shift operation.
