PURPOSE: An active geometry control suspension system is provided to variably control a mounting point of a lower arm on a sub-frame for providing a negative camber to an outer rear wheel during a turn, thereby increasing wheel grip force on road and thus improving steering performance of a vehicle. CONSTITUTION: An active geometry control suspension system comprises a slide bracket(1), a fixing frame (3), a driving motor(5), a rotary plate(7), a rotary lever(9), and a fixing bracket(11). The slide bracket is connected to an end of a lower arm(13) of a vehicle body by a hinge and includes a guide rail(19) formed in upper and lower direction in the center of an inner surface; a fixing grooves(G1, G2) formed in the upper and the lower portion of the inside; and a first hinge pin(HP1) installed on one side. The fixing frame includes a rail groove(21) on an exterior surface for guiding the guide rail to slide in upper and lower direction. The driving motor includes a rotary shaft(5a) installed passing through the fixing frame in an axial direction. The rotary plate is arranged on both sides of the fixing frame to be installed on the rotation axis of the driving motor and includes a rotary pin(RP) in one side. The rotary lever is fixed to the other side of the fixing plate by a second hinge pin(HP2) and includes a first and a second rotary pin which are installed at a first and a second slot(SL1, SL2) of the middle portion and the front end portion, in order to be respectively connected to the rotary plate and the slide bracket. The fixing brackets are arranged in the both sides of the fixing frame to correspond to each other, which are inserted in the slide bracket through the upper and the lower fixing ends(E1, E2). |
