  • Transmission for performing reliable continuously-variable-speed operation through gear meshing, and vehicle-use continuously-variable transmission device using it
    Patent number: 6645106
    Abstract: A transmission for performing a reliable continuously-variable-speed operation by using gear meshing with a minimized power loss, and a vehicle-use continuously-variable transmission device that uses it to provide a continuously-variable-speed change ratio optimal for an engine output; specifically, a dual continuously-variable transmission device for effecting a secondary speed change of increasing or decreasing an output-speed increasing ratio when the rotating speed of a turbine shaft is increased or decreased with the rotation speed of a sub-drive speed-change sun gear fixed.
    Type: Grant
