The invention relates to a single-coil spring double-damping suspension system with completely decoupled rigidity. The single-coil spring double-damping suspension system is a vehicle suspension system based on ADAMSCar multi-body dynamics simulation. The single-coil spring double-damping suspension system comprises an upper cross arm, a lower cross arm, triangular arms, a push rod, a left guide rod, a right guide rod, spiral springs, dampers, an anti-roll rod, anti-roll rod connecting rods and anti-roll rod force arms, the upper cross arm and the lower cross arm are connected with a wheel upright and a vehicle body; two ends of a push rod are respectively hinged with the lower cross arm and the triangular arm; the left guide rod and the right guide rod are hinged to the triangular arm respectively, a piston rod of the left guide rod extends into a piston through hole of the right guide rod, the left guide rod and the right guide rod are sleeved with the spiral springs, the two dampersare hinged to the triangular arms on the two sides respectively, and the triangular arms are hinged to the anti-toppling rod force arms fixedly connected to the two sides of the anti-toppling rod through the anti-toppling rod connecting rods. According to the invention, the linear rigidity and the angular rigidity of the suspension are completely decoupled, and meanwhile, the lightweight design requirement is fully realized.
