1. transmission device, wherein, in one first power range driving power from live axle (2) by can stepless adjustment its pass to driven shaft (17) for the transmission device of stepless speed variator (5) in form, stepless speed variator (5) has the toric surface shape rolling surface (6 and 8 or 7 and 9) of a main shaft (4) and paired collaborative work, some rolling elements (10) turn round between rolling surface, andA transmission device (5) and a planetary type gear transmission unit (18) by can stepless adjustment in one second power range transmit,Wherein, first power range is corresponding to one first forward driving range, and this moment, driving power was passed to driven shaft (17) by stepless speed variator (5), and planetary type gear transmission unit (18) is done as a whole rotation;

  • Second power range is connecting this first power range, and it is corresponding to one second forward driving range;

    Stepless speed variator (5) and planetary type gear transmission unit (18) be tandem arrangement vertically;

    The output terminal of stepless speed variator is connected with an axle (14) by a transmission joint (12) that contains a gear stage, and a member (19) of this axle and planetary type gear transmission unit (18) couples together in transmission,It is characterized by;

    Establish a starting member (3) in that stepless speed variator (5) is preceding, it is designed to the multidisc clutch of wet type operation;

    In second forward driving range, driving power is passed to driven shaft (17) by planetary type gear transmission unit (18), implement power shunt and a virtual power in this case and flow through stepless speed variator (5) in planetary type gear transmission unit (18), this virtual power is gone up and the driving power stack at the main shaft (4) of stepless speed variator (5).
