1. an infinitely variable transmission, it comprises:

  • Rotary type gearbox input end and rotary type gear box output end;

    With the speed changer of rotary type speed changer input end and rotary type speed changer output terminal, and between its input end and output terminal, be suitable for the variator ratio transmission driving force with continuous variable;

    Form first gearing (R1) of the first drive path that described gearbox input end is connected with the first axle (17), make the First Speed ratio between described gearbox input end and described the first axle (17) be the function of variator ratio and reduce along with the variator ratio increasing;

    WithForm the second gearing (R2) that by described speed changer, described gearbox input end is connected to the second drive path of the second axle (19), make the second speed ratio between described gearbox input end and the second axle be the function of variator ratio and increase along with the variator ratio increasing, and there is a specific variator ratio, i.e. " synchrom esh transmission ratio ", when in this ratio, the first axle (17) equates with the speed of the second axle (19);

    Described gearbox also comprises regime clutch (18,20), this regime clutch (18,20) optionally described the first axle (17) or described the second axle (19) are connected on described rotary type gear box output end, so that the first gearbox pattern and the second gearbox pattern to be provided;

    AndOne-way clutch device (22,24), described one-way clutch device (22,24) with described regime clutch (18,20) parallel connection, prevent that the speed of described the first axle from exceeding the speed of described the second axle, thereby prevent that transmission ratio rate is lower than described synchrom esh transmission ratio;

    Wherein, described regime clutch (18,20) comprises two regime clutch, and described one-way clutch device (22,24) comprise two overrunning clutchs, to prevent occurring reversal phenomenon in the related rotation of its input end and output terminal;

    Wherein, first mode clutch (18) is optionally connected to described the first axle (17) on described output shaft of gear-box;

    And second regime clutch (20) optionally described the second axle (19) is connected on described output shaft of gear-box;

    The first overrunning clutch (22) is in parallel with described first mode clutch (18), and the second overrunning clutch (24) and described the second regime clutch (20) parallel connection;

    AndDescribed the first drive path is combined with planetary gear set.
