Transmission for performing reliable continuously variable speed shifting through gear engagement and continuously variable transmission for vehicle using the same

摘要

The present invention relates to a transmission for performing a reliable continuously variable speed shifting operation utilizing gear engagement while minimizing loss of power, and to a continuously variable transmission for a vehicle which provides an optimum transmission ratio to an output of an engine by utilizing it, and a sub drive This is a double continuously variable transmission in which secondary speed change in which the output increase ratio is increased or decreased by increasing or decreasing the rotational speed of the turbine shaft by fixing the number of revolutions of the shift sun gear. Since the distributed rotational force is synthesized in the process of the shifting process, the power consumption is almost exhausted during rotation of the sub drive sun gear. By applying this to an automobile, the speed of the engine, the speed of the throttle opening, the number of revolutions of the transmission sun gear, the rotational speed of the transmission sun gear, the brake pressure, etc. are calculated by the controller (TCU) and converted into the conversion time and the optimum transmission ratio is optimum in the real time It provides flexible, easy to operate fuel, reducing output and reducing smoke and noise.
