Question:
What is the NuVinci® CVP?
Answer:

The NuVinci CVP is a continuously variable and broadly applicable technology, with applications for almost any product using a mechanical power transmission. NuVinci technology combines the advantages of a toroidal traction continuously variable transmission (CVT) with the advantages of a time-proven planetary gear arrangement. The NuVinci CVP is the only continuously variable transmission that has a planetary gearset's advantages of high torque density, versatility of use, inline shafts and low production cost. As a result, NuVinci technology is the only technology potentially capable of replacing the planetary gear transmission – in every application – as virtually a plug-and-play replacement.

Question:
CVTs have been around for a long time. Why have they not become commonplace?
Answer:

The use of CVTs has not become widespread due to multiple problems including scalability challenges, questionable reliability and durability, high cost and other factors. Despite some obvious drawbacks, some manufacturers such as Ford, Nissan, Honda and Audi have implemented limited production with old CVT technology because the market need was so great. However, with the development of the NuVinci CVP, the technical roadblocks now have been eliminated – clearing the way for a wide range of CVP applications for which markets are ready and waiting.

Question:
How is the NuVinci® CVP different from conventional transmissions?
Answer:

The NuVinci CVP offers a wide range of advantages over conventional transmissions. These advantages include: • Less complexity • Greater powertrain system efficiency • Greater acceleration and optimum performance • Easier shifting • Ability to accept multiple inputs while varying speed and managing torque • Multiple power outlets such as for a power take off (PTO) application • Easier to package and potentially lighter • Easier and less costly to manufacture • Greater scalability and potential to reuse tooling • Improved hill-climbing

Question:
How is the NuVinci® CVP different than traditional IVTs and CVTs?
Answer:

Unlike conventional transmissions that have a fixed number of gears or output speeds, a continuously variable planetary transmission (CVP) has an unlimited number of speed ratios between its high and low limits. This allows the engine or motor to stay within its peak efficiency or peak power operating speed more than the conventional transmission. The NuVinci technology is a CVP that is based on a set of rotating, tilting balls clamped between two rings. Torque from an engine, motor or other input source is transferred through an input disc to the balls via the contact between the balls and the input disc. The torque is then transmitted through the balls, each of which rotates about its own separate axle, and then to the output disc via the contact between the ball and the output disc. The input disc and output disc are clamped onto the balls tightly so that the requisite amount of clamping force is provided for the amount of torque being transmitted. A transmission fluid provides traction, and prevents metal to metal contact, between the balls and discs while providing lubrication for bearings and other components. The speed of the input disc compared to the speed of the output disc, or speed ratio, is controlled by the angle of the ball axles relative to the axis of the transmission.

Question:
How much more will the NuVinci® technology add to the price of my next vehicle?
Answer:

Unlike conventional transmissions that have a fixed number of gears or output speeds, a continuously variable planetary transmission (CVP) has an unlimited number of speed ratios between its high and low limits. This allows the engine or motor to stay within its peak efficiency or peak power operating speed more than the conventional transmission. The price will ultimately be determined by the company integrating NuVinci technology into their products. However, because NuVinci-enabled products can be manufactured with standard manufacturing processes and traditional materials, the cost should be reasonably attractive. When you consider the fuel economy savings and the reduced wear and tear on related components, we believe there will be a favorable payback.

Question:
How can I get NuVinci® on my next vehicle?
Answer:

NuVinci technology is currently featured on many bicycles and eBikes. Fallbrook is in various stages of discussions, development agreements and/or licensing partnerships with companies in its primary target industries, including the automotive, heavy-duty commercial vehicle, electric vehicle, lawn and garden, and industrial equipment industries. We expect NuVinci technology to be commercialized in a variety of applications over the next several years. Please check our website regularly for the latest news on commercial products equipped with NuVinci technology.

Question:
How does the NuVinci® accessory drive technology improve fuel economy without sacrificing performance?
Answer:

The NuVinci CVP technology is at the heart of Fallbrook's accessory drive system. This game-changing technology in an air conditioning compressor, for example, decouples compressor speed from engine speed, enabling the compressor to operate in its optimal range based on demand regardless of engine RPM. As a result, the NuVinci compressor drive delivers the ideal compressor speed all the time – optimizing air conditioning operation and performance while putting less strain on the engine and improving fuel economy. This same system optimization, fuel savings and performance improvements can be similarly realized in other accessory applications.

Question:
How much more will an accessory system cost with NuVinci® technology?
Answer:

The price will ultimately be determined by the company integrating the technology into their accessory system. However, because NuVinci-enabled products can be manufactured with standard manufacturing processes and traditional materials, their cost should be reasonably attractive. When you consider the fuel savings, performance gains and the reduced wear and tear on the accessory, we believe there will be a significant payback to the vehicle owner.
