Field of the Invention The present invention relates to a wheel balance control apparatus in which a front wheel of a vehicle is steered at a constant road according to a steering angle of a steering wheel. Is installed, the pressure sensors (7, 8) are respectively installed on both chambers (5, 6) of the pile cylinder (4) for directly operating the tie rod for connecting the steering handle (1) and the wheel, A switching valve 12 actuated by the solenoid 11 is installed in the flow paths 9 and 10 connected to the power cylinder 4, while the pressure sensors 7 and 8 are electrically connected to the comparator 13. The comparator 13 and the angle sensor 3 are connected to the microprocessor 14, and the microprocessor 14 has a structure in which the solenoid 11 and the switching valve 12 are connected to each other. Change the steering angle of the steering wheel (1) and the pressure of the power cylinder (4). By replenishing the pressure of the power cylinder 4, the wheel balance is automatically corrected.
