VERFAHREN ZUR STEUERUNG EINES MECHANISCH-HYDRAULISCHEN GETRIEBES

摘要

A method of power transmission in a mechanical/hydraulic type transmission, in which changeover is smoothly effected between hydraulic transmission and mechanical transmission. Provided are a hydraulic type transmission for transmitting to the outside (300) a mechanical power (Pm), which has been converted by a hydraulic motor (42), by engagement of a clutch (A), and a mechanical type transmission for transmitting to the outside (300) a mechanical power (Po) by engagement of a clutch (B). Upon changeover from the hydraulic type transmission to the mechanical type transmission, releasing of the clutch (A) is performed after engagement of the clutch (B) is started and before engagement of the clutch (B) is completed.
