The invention discloses a damping suspension device for a semitrailer, and belongs to the technical field of trailers. The damping suspension device comprises a transverse damping device and a longitudinal damping device which are perpendicular to each other. The transverse damping device comprises a support, an elastic part I, an elastic part II and a driving part; the longitudinal damping device comprises steel plate springs installed at the two sides of the support; and when a vehicle body descends, the transverse damping device and the driving part have three statesat least. The number of supporting points of the suspension device is four, the supporting and damping effects are enhanced, the vehicle body can be prevented from rollover due to inclination, and therefore the vehicle body is corrected.
