TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION

摘要

In a continuously variable transmission including: a first transmission unit including a first input disc and a first output disc disposed coaxially and a power roller tiltably interposed between these discs; and a second transmission unit disposed coaxially with the first transmission unit, including a second input disc and a second output disc disposed coaxially and a second power roller tiltably interposed between these discs, and disposed such that a back surface of the second input disc is opposed to a back surface of the first input disc, a tubular back surface cylinder wall is provided on each of the back surfaces of the first input disc and the second input disc so as to project therefrom.

1. A toroidal continuously variable transmission comprising:
a first transmission unit including:
a first input disc and a first output disc disposed coaxially with each other; anda first power roller tiltably interposed between the first input disc and the first output disc and configured to transmit a driving force from the first input disc to the first output disc; and a second transmission unit disposed coaxially with the first transmission unit, the second transmission unit including:
a second input disc and a second output disc disposed coaxially with each other; anda second power roller tiltably interposed between the second input disc and the second output disc and configured to transmit a driving force from the second input disc to the second output disc, the second transmission unit being disposed such that a back surface of the second input disc is opposed to a back surface of the first input disc, wherein the back surface of the first input disc is provided with a back surface cylinder wall of a tubular shape protruding therefrom so as to be concentric with the first input disc, and the back surface of the second input disc is provided with a back surface cylinder wall of a tubular shape protruding therefrom so as to be concentric with the second input disc.
