A Continuously Variable Transmission (CVT) that uses a gear which changes gear size, along with an innovative gear train to achieve different gear ratios. The CVT overcomes the disadvantages of other designs, as it is a purely mechanical drive system. The CVT is an electro-hydraulically operated device, allowing infinite precision and control, using custom configurations, based on information from engine management systems installed in most modern vehicles. The CVT provides improved vehicle fuel efficiency, acceleration, ease of vehicle drivability and increased power transfer. The CVT minimizes engine stress due to a lower range of revolutions. Also, stress on the vehicle's drive-train is minimized, as there is no sudden transition in drive-shaft RPM as the gears change. The CVT allows an engine to run at an optimal range for fuel efficiency and torque, as the engine no longer has to cycle through the normal range of revs as the gears change. |
