Abstract:
1. An electronic gearshift device of a transfer case assembly for a four wheel drive vehicle, comprising: a motor: a camshaft rotatably driven by the motor; a rail member separated from the camshaft by a predetermined distance and positioned parallel to the camshaft; first and second forks installed on the rail member such that they are spaced apart from each other; and a cam fitted around and supported by the camshaft to selectively operate the first or second forks on the rail member to thereby effect gearshift, wherein the cam is formed with first and second operating sections for operating the first fork to effect conversion between a four wheel driving scheme and a two wheel driving scheme, and third and fourth operating sections for operating the second fork to effect conversion between a four wheel high speed driving mode and a four wheel low speed driving mode.
