CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PCT No. PCT/EP98/00115 Sec. 371 Date Jul. 7, 1999 Sec. 102(e) Date Jul. 7, 1999 PCT Filed Jan. 10, 1998 PCT Pub. No. WO98/31954 PCT Pub. Date Jul. 23, 1998The invention is based on a continuously variable transmission comprising a mechanical power branch and an electronically controlled hydraulic power branch which can be adjusted via a swash plate (7), a summarizing transmission and a multi-stage transmission with hydraulically actuated, force-locking shift elements (11-14). The shift signals of the shift elements (11-14) are generally triggered when a shift or synchronizer speed is reached. Thereafter elapses a response or reaction time and an adjusting time until the shift elements (11-14) are engaged. This results in long clutch shift processes. It is proposed that the response and engagement times of the shift elements (11-14) be compensated by a control unit.
