ABSTRACT:
A stepless automatic variable transmission with gears in a state of constant meshing which is operational without the need for disengaging or changing the gears such that the rotational output power can be varied to effect a neutral, low speed, medium speed, high speed, overdrive or reverse rotation by selecting a stepless automatic speed change method or a manual speed change method, and which includes a speed change system, an overdrive system and a speed change controlling system.
The assembly of speed change system (10, 110, 310, 410, 510, 610), the overdrive system (50, 360, 660, 760) and the speed change controlling system (80, 180, 380, 680, 780) can vary with each of the systems combined to result in numerous stepless automatic variable transmissions. To effect speed changes low speed, medium speed, overdrive, and reverse rotation brake means are used. Also, either the manual speed change method or the automatic speed change method can be selected.
