Abstract:
A toroidal continuous variable transmission comprising thrusting means secured to an input shaft and generating a thrust force along an axial direction of the input shaft, a first input disk arranged confronting to the thrusting means and supported for rotation as well as axial movement relative to the input shaft, a second input disk mounted for axial movement with respect to the input shaft, output disks arranged in opposition to the first and second input disks, one to each input disk, power rollers arranged between the paired input and output disks so as to change continuously the rotational speed of the first and second input disks, depending on tilt angles to the disks, thereby transmitting a power of changed speed to the output disks, reverse means for transmitting rotations of the output disks in a opposite rotational direction, to an output shaft, a forward clutch for shifting the reverse means from a torque-transmitting phase to a freewheeling phase and vice versa, a planetary gear system engaged to the input shaft, and a direct clutch for changing over operating phases of the planetary gear system.
