A double wish bone suspension of a vehicle is provided to regulate king pin off set value by dividing a knuckle into an upper and lower knuckle, sliding each other, and varying knuckle with electromagnet force. A double wish bone suspension of a vehicle comprises a lower knuckle and an upper knuckle(10), a permanent magnet, a control unit, and a bolt for a lead wire(40). The upper and the lower knuckles are slid on each other. The permanent magnet is embedded in the lower knuckle, and of which N pole and S pole are formed to opposite direction. The control unit receives a speed signal, a roll signal, a horizontal G signal and judges flow and intensity of current. The bolt for the lead wire generates electromagnetic force to the permanent electromagnet by receiving flow and intensity of current from the control unit. The bolt for the lead wire assembled to the upper knuckle to vary king pin shaft offset value by controlling ascending height of the upper knuckle and generating electromagnetic force between the permanent magnet and the current supplied the control unit signal. |
