Suspension system for vehicles

A suspension system for vehicles comprising:

• a wheel carrier for rotatable supporting a wheel;
• an upper control arm having a first end connected to an upper end of the wheel carrier and a second end for pivotally connecting to a frame of the vehicle;
• a lower control arm having a first end connected to a lower end of the wheel career and a second end for extending toward the frame of the vehicle;
• and
• a damper for converting an up-and-down motion of the lower control arm caused by shock transmitted from a road surface into a linear motion in a longitudinal direction of the vehicle and cushioning the linear motion, the damper being mounted on a side member and connected to the lower control arm, the damper comprising:
• an upper casing fixedly mounted to a side member of the frame, the upper casing being hollow,
• a lower casing integrally formed downward from a right end portion of the upper casing and having a bottom end bent toward the lower control arm, the lower casing being hollow,
• a beam fixedly mounted on the lower control arm and extending into the bottom end of the lower casing, a first gear being formed on an end of the first shaft extending into the lower casing,
• a first shaft extending along a length of the lower casing and into the upper casing, and having a second gear formed on a bottom end thereof to mesh with the first gear of the beam and a third gear formed on a top end thereof,
• a fourth gear rotating on a shaft mounted to an interior of the damper and meshed with the third gear,
• a second shaft provided extending between the lower casing and the upper casing, and having a fifth gear on a lower end thereof meshing with the fourth gear and a pinion on an upper end thereof,
• an elastic member provided in a leftward end of the upper casing, and
• a shock absorber mounted in the upper casing and having a damper rod extending in a leftward direction to be fixed to a left end of the upper casing and a rack bar extending in a rightward direction such that a rack portion formed thereon meshes with the pinion of the second shaft, the damping rod of the shock absorber extending through a middle of the elastic member.
