Frictionless CVT Concept

Unlike other CVTs that use belts or steel balls, this is not friction based so it should be more efficient and be able to withstand higher torques without any slippage.

The main problem that remains is the vibration of the whole mechanism and osciallatory torque transmission.  A possible solution could be using 2 such mechanisms in parallel working in opposite directions so the forces generated by the rod movement are canceled.

The durability of the roller clutch can also be a problem, having to withstand billions of high torque couplings.
