5.3.15 Disadvantages toroidal variator
One of the disadvantages of this type of variators is that the main working parts are made out of metal. And as we all know from the school physics course, metal-to-metal friction has a very low efficiency. In order to compensate for this, all working parts must be made out of
high-strength materials and pressed against each other with great force. These disadvantages are supplemented by the high cost, and the high cost of both manufacturing and maintenance.
