摘要
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. Since a distributed torque is synthesized during is applied to automobiles to provide elaborately, flexibly and in real time a speed change ratio which is obtained by computing an engine output, a car speed, a throttle opening ratio, a variable-speed sun gear rotating speed, and a brake pressure by using a controller (TCU), is changed in a time-transforming way, and is optimum for running conditions and road condition, thereby saving on fuel, enhancing an out put, decreasing soot and smoke and noise, and yet ensuring a comfortable running.
