Naudic CVT : towards a more fuel-efficient future

Poised to become one of the most important discoveries in the search for lower fuel consumption and reduced emissions since the invention of the automobile, the revolutionary new Naudic Continuously Variable Transmission (CVT) concept, is making a significant impact in the vehicle and engineering industries.

Offered under licence to manufacturers world-wide, the Naudic technology is suitable for development in a wide range of vehicles and machines.

The Naudic CVT technology is an easy to apply innovation with significant benefits for the environment because it lowers fuel consumption and reduces emissions.

Gearing up for Change

The search for a more efficient "shifting" has culminated in today's sophisticated automatic transmissions reaching high levels of sophistication (The best examples being the current Ferrari F1 and BMW SMG II AMTs which shift in a matter of milliseconds). But this marks the performance apex of such systems. Even these engineering feats cannot fully eliminate engine power downtime during shifts, or shock loading of the drive train. And they remain shackled to a pre-determined number of limited gear ratios.

The new Naudic CVT technology solves these problems and heralds a significant departure from conventional thinking, leading to optimal transmission efficiency and performance .

Significant Advantages

The Naudic Continuously Variable Transmission (CVT) technology, offers significant advantages through small incremental ratio changes with no shock loading or loss of power throughout the operational envelope of the engine. Fuel savings of 18% are possible with such transmissions.

Universal Application

Unlike the two most commonly used CVT concepts, (CVTs that use traction fluid coupling and CVTs that use variable hydraulic drive), the Naudic concept eliminates the shortcomings of conventional CVTs for universal application in the vehicle industry. This is because traction fluid CVTs are only suitable in low-to-medium kilowatt/torque applications, and variable hydraulic drive CVT's are best suited to hi-torque/hi-kilowatt applications such as in tractors: The Naudic system can be utilised across a wide range of applications such as:

  • Passenger Vehicles
  • All Terrain vehicles
  • Motor Racing applications
  • Trucks and Buses
  • Construction Vehicles
  • Agricultural Vehicles
  • Mining Vehicles
  • Military Vehicles
  • Machine Tools

Enhanced Efficiency

Even though a conventional CVT provides better fuel economy (by 18%) compared to a manual gearbox (which changes gears in steps and is limited mainly to 5 ratios, thus creating rpm changes to the engine of anywhere between 20% and 70%), it is inherently less efficient by a factor of 10% - 20% than a manual gearbox. The ultimate in CVT technology is a CVT that has transmission efficiencies as good as a manual gearbox. TheNaudic CVT concept delivers this and is therefore capable of exceeding the fuel savings of 18% currently being quoted for conventional CVTs.

A Unique new Concept

The Naudic innovation in transmission technology represents a radical departure from conventional CVT science. Using neither traction fluid nor dynamic friction interfaces, the Naudic system is a unique new concept in CVT transmissions.

A New Era in Powertrain Efficiency

The Naudic concept is a giant step towards higher efficiencies and greater economy in vehicle and machine transmission applications. It brings an effective new weapon to a world struggling with global warming and the expense of inefficient fuel consumption.
