摘要： A car height control apparatus comprising: a weight sensing section for sensing a rear shaft force of a car; a bellows in which one end is fixed at the lengthwise frame, and the other end is adhered closely to a leaf spring that supports the lengthwise frame; an air tank for storing gas to be used in the bellows; and a control section for controlling the quantity of compressed air that inflows into the bellows by the weight sensing section signal. When unbalancing force is concentrated on rear shaft, load sensor generates the signal and transmits it to the controller. The controller that has received the signal opens the leveling valve to supply the compressed air toward the bellows. The bellows which is supplied with the compressed air increases its volume along the longitudinal direction, so the distance between lengthwise frame and leaf spring is greater. Finally, spring and shock absorber of suspension system recover and maintain the normal car height.
