Infinitely Variable Geared Transmission

The D Drive is a geared continuously variable transmission. Most continuously variable transmissions use a belt running across two cones. However, a geared transmission can transfer greater torques or loads before slipping. Continuously variable transmissions are important for fuel efficiency because they allow the engine to always operate at its most efficient speed. Then the transmission changes the gearing ratio as needed to run the output shaft ( the wheels ) at the desired speed. If the D Drive can be developed to the point of automobile usage, it could mean a big step forward in vehicle fuel economy. Let us hope the D Drive helps us save on gas in the near future!
