The invention discloses a multi-mode output intermediate-shaft-free stepless speed change transmission system which is characterized in that an engine output shaft is connected with a power output shaft through a joint sleeve, and the power output shaft is simultaneously connected with a planet carrier and a driven disc of a clutch C2; a generator rotor shaft is connected with a sun wheel shaft through a joint sleeve, and the sun wheel shaft is connected with a sun wheel; a rotor shaft of the motor is connected with an input shaft of a gearbox through a joint sleeve; the input shaft of the gearbox is simultaneously connected with a gear Z1, a driving disc of an overrun clutch and a driven disc of a clutch C1; a driven disc of the overrun clutch is connected with a gear Z3; the C1/C2 driving disc is connected with a planetary gear ring; a central transmission driving shaft is simultaneously connected with a driven disc of a clutch C3 and a gear Z4; a driving disc of the clutch C3 is connected with the gear Z2; and the gear Z1 is meshed with the gear Z2, and the gear Z3 is meshed with the gear Z4. Therefore, the function that the vehicle runs in the three CVT modes can be achieved, and the purposes of saving oil and reducing emission of the whole vehicle can be achieved.

    本发明公开了一种多模式输出无中间轴的无级变速传动系统,包括:发动机输出轴通过接合套与动力输出轴联结,动力输出轴同时与行星架和离合器C2从动盘联结;发电机转子轴通过接合套与太阳轮轴联结,太阳轮轴与太阳轮联结;电动机转子轴通过接合套与变速箱输入轴联结,变速箱输入轴同时与齿轮Z1、超越离合器主动盘、离合器C1从动盘联结;超越离合器从动盘与齿轮Z3联结;C1/C2主动盘与行星齿圈联结;中央传动主动轴同时与离合器C3从动盘和齿轮Z4联结;以及离合器C3主动盘与齿轮Z2联结;其中齿轮Z1与齿轮Z2啮合,齿轮Z3与齿轮Z4啮合。借此,能够实现了车辆在三种CVT模式下运行的功能,以及能达到整车省油、减低排放的目标。
