The present invention relates to a steering apparatus with a gear ratio changing ball joint. More specifically, a steering apparatus with a gear ratio changing ball joint which includes a variable drive unit composed of a screw shaft driven by a motor connected to a knuckle arm, and which can adjust revolutions or a revolution ratio of a knuckle (or wheel) to the identical rack strokes when a ball joint unit connecting the variable drive unit and a tie rod is moved by the variable drive unit in an axial direction of the knuckle arm. To this end, the steering apparatus, which is provided in a joint portion between the tie rod and the knuckle arm to adjust a rotation angle of a knuckle, comprises: the variable drive unit provided along a length direction of the knuckle arm; and the ball joint unit connecting the tie rod and the variable drive unit and moved by the variable drive unit in the axial direction of the knuckle arm. |
