Abstract
(EN)
Disclosed are a planetary gear locking apparatus, a dry torque converter, for an electric vehicle, having same, and a control method therefor. The dry torque converter for an electric vehicle, according to an embodiment of the present invention, comprises: a planetary gear connected to an input shaft by means of a first element, connected to an output shaft by means of a second element, and variably connected to a fixed part by means of a third element; at least one eddy current torque generation unit provided between the first element and the second element and generating an eddy current so as to be controlled by means of the speed of the output shaft; a front cover integrally connected to the input shaft and the first element and having the planetary gear mounted therein; a back cover arranged so as to be near the output shaft, and coupled to the front cover; a planetary gear locking apparatus comprising a locking unit which is provided between the second element and the third element so as to control the connection between the third element and the fixed part regardless of the rotational direction of the output shaft, in accordance with the rotational speed of the output shaft; and lock-up mechanisms which are provided on both sides of the second element with respect to the axial direction, selectively make contact with the inner side of the front cover and back cover, respectively, due to a centrifugal force generated in accordance with the rotational speed of the output shaft, and directly connect the input shaft and the output shaft.
