The present invention discloses a chassis articulation system of articulated vehicle, comprising a front frame, a rear frame, a turntable bearing, and a left buffer and a right buffer which are installed on two sides of said turntable bearing. The hydraulic control oil circuit on each buffer is set as: when a rod cavity of hydraulic cylinder is compressed, the hydraulic oil in the rod cavity is returned to an oil storage tank via a damping oil circuit with a set damping, and the hydraulic oil in the oil storage tank is sucked to a rodless cavity via an oil circuit without a damping; when the rodless cavity of the hydraulic cylinder is compressed, the oil circuits by which the hydraulic oil is returned from the rodless cavity to the oil storage tank and the oil circuit by which the hydraulic oil is sucked from the oil storage tank to the rod cavity are both oil circuits without a damping. In this case, when a vehicle turns, the piston rod of one buffer's hydraulic cylinder is extended to provide the buffer with a buffering force with a set damping and the piston rod of the other buffer's hydraulic cylinder is compressed to provide a very small buffering force, making the vehicle turn more smoothly, more stably and more safely; when a vehicle slews, the buffer produces a very small damping torque to make the vehicle slew more quickly and easily.
