Abstract
A toroidal type continuously variable transmission, in which there are provided a plurality of sets of speed change units each having rollers sandwiched between the opposed faces of input discs and output discs and in which the individual input discs are coupled to an input shaft whereas the individual output discs are coupled to an output shaft. The individual input discs or the individual output discs are held rotatably relative to each other, and the individual input discs are coupled in a torque transmitting manner to the input shaft through individual chains.
Claims5
A toroidal type continuously variable transmission, in which a plurality of sets of such speed change units are interposed between the opposed faces of input rotary members and output rotary members as each has power transmitting rolling members inclined to vary the torque transmitting portions to those faces and in which the input rotary members at individual speed change units are coupled to a single input member whereas the individual output rotary members are coupled to a single output member, characterized by comprising:
- a holding mechanism for holding said input rotary members or said output rotary members rotatably relative to each other;
- and
- a wrapping transmission mechanism for coupling said input member and the individual input rotary members individually in a torque transmitting manner or said output member and the individual output rotary members individually in a torque transmitting manner.
