Is the Naudic iCVT patent simply an improvement on current CVT mechanics?

No, the Naudic iCVT is a completely new concept, radically different from conventional ratcheting and traction fluid CVTs, which it supersedes. Extensive research has shown it to be the only working, frictionless, positive drive CVT system in the world and it is fully protected by patents.

Efficiency and Emissions

The Naudic iCVT is likely to exceed current CVT fuel saving claims (18%), because, being a positive drive system, it does not suffer from the friction and or hydraulic control losses associated with conventional, traction fluid systems. Compared to 6 speed AMTs, automatics, heavy-duty ‘PowerShift’ transmissions and high Nm belt CVTs, the Naudic iCVT offers significantly improved fuel-efficiency with the proportional reduction in emissions.

The Best of Both Worlds

The Naudic iCVT from Barloworld CVT Technologies combines the best of CVTs and AMTs. The concept is based on a variable sprocket which alters ratios by either adding or removing a single tooth in the process of the chain engaging the sprocket. The primary difference between the Naudic innovation and the many other conventional CVTs on international patent databases, is that most of the others lack proper synchronisation, relegating them to very low rpm, low power applications such as in bicycles.
