The present disclosure provides a suspension system with damping and buffering properties, comprising a suspension assembly, a wheel train assembly and a track assembly, the suspension assembly comprises a suspension lateral plate, an approach plate, a first elastic element, a tensioning assembly, a second elastic element, an oscillating arm plate and a damping element; the wheel train assembly comprises a first approach wheel, a second approach wheel, a first load-bearing wheel, a second load-bearing wheel, a track supporting wheel and an actuation wheel. A high stability of a mobile platform moving through obstacles can be realized by assembling the approach plate, the first elastic plate and the damping element into a loading and shock absorbing module in the present disclosure.
