The invention discloses a shockproof articulated car, comprising an underframe, fixed frames, wheels, wheel axles, external shock damping devices, internal shock damping devices and external springs; a plurality of opposite fixed frames are uniformly arranged at two sides below the underframe and connected with the wheels by means of the wheel axles; the external shock damping devices are arranged at two sides of the fixed frames; the external springs are arranged on the external shock damping devices; and the internal shock damping devices are arranged in the external springs. According to the shockproof articulated car, two layers of the shock damping devices are adopted, that is, the internal shock damping devices are arranged in the external springs of the external shock damping devices; the shock is damped by the external shock damping devices and then is damped at the second time by means of the internal shock damping devices, so that the shock damping effect is better and the stable running of the articulated car during cargo transportation is guaranteed better.
