PURPOSE: A suspension system for vehicles is provided to reduce the vehicle accessories and parts by using the axle shaft supporting wheels as a suspension arm without using a plurality of links and guarantee precise and various movement of wheels by forming the cam surface with various tracks in response to the instantaneous centers. CONSTITUTION: A suspension system for vehicles includes an axle shaft(8) formed with spherical inner end and supporting wheels outside, a cam assembly including a cam(14) spherically contacting the inner surface of the axle shaft and having an inner cam surface(12) with a curvature of instantaneous center track of wheel with relation to the vehicle body(10) when wheels move up and down, a cam contact member(20) to contact the cam surface, and an insulation member(22) for absorbing impact in the axial direction from the axle shaft, an elastic element(18) for elastically connecting the axle shaft to a vehicle shaft between the inner end part of the axle shaft and the vehicle, and a buffering element(28) for reducing the vertical road on the outside of the axle shaft.
