PURPOSE: An axial suspension system is provided to improve the roll stiffness of the axial suspension system by using the length variation of a laminated spring generated in turning a vehicle and to increase the operation stability of the vehicle. CONSTITUTION: An axial suspension system is composed of an axle; left and right laminated springs mounted to the axle; a U-bolt for fixing the laminated springs to the axle; left and right pipes fixed to the left and right sides of a vehicle body, respectively; left and right upper bushes inserted into the left and right pipes and formed with through-holes, respectively; left and right lower bushes inserted into ends of the laminated springs and formed with through-holes, respectively; a left shackle comprising a left upper shackle pin(51A) inserted into the through-hole of the left upper bush, a left lower shackle pin(51B) inserted into the through-hole of the left lower bush, and a left inner plate(51C) integrally combined to the left upper and lower shackle pins; a right shackle plate comprising a left upper shackle pin inserted into the through-hole of the right upper bush, a right lower shackle pin inserted into the through-hole of the right lower bush, and a right inner plate integrally combined to the right upper and lower shackle pins; left and right outer plates combined to left and right upper shackle pins and left and right lower shackle pins of the left and right shackle plates; left and right arms fixed to the left and right shackle plates and formed with serration at the insides, respectively; and a torsion bar formed with serration at both ends and inserted and installed to the serration of the left and right arms.
