DRY TYPE TORQUE CONVERTER FOR ELECTRIC VEHICLE AND CONTROLLING METHOD THEREOF

The dry type of torque converter for the electric vehicle according to an exemplary embodiment of the present invention includes: a planetary gear including a first element connected to an input shaft, a second element connected to an output shaft, and a third element variably connected to a fixing unit; at least one eddy current torque generation unit provided between the first element and the second element and generating an eddy current to be controlled by a speed of the output shaft; a front cover integrally connected to the input shaft and the first element and incorporating the planetary gear; a one-way clutch interlocking one-direction connection of the third element and the fixing unit and connecting them to each other; a back cover provided at the output shaft side to be coupled with the front cover; and a lock-up mechanism respectively provided on both sides of the second element based on an axis direction and directly connecting the input shaft and the output shaft while being respectively in selective contact with the inner surfaces of the front cover and the back cover by the centrifugal force generated depending on the rotation speed of the output shaft.
