STUFENLOSES GETRIEBE
摘要:
The invention concerns a continuously variable transmission comprising: a mechanical power branch and an electronically controlled hydraulic power branch which can be adjusted by means of a swash plate (7); a summarizing transmission; and a multi-stage gearbox with hydraulically operated, 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 attained. This is followed by a response or reaction time and an adjusting time, until the shift elements (11 - 14) are engaged, which results in long clutch shift processes. According to the invention, the response and engagement times of the shift elements (11 - 14) are compensated by a control unit.
