The invention provides an oil-gas suspension device for a trailer/semitrailer. The oil-gas suspension device for the trailer/semitrailer comprises a plate spring support and a plate spring, wherein a middle segment of the plate spring is fixed on a car shaft through a fixed device, a packing ear which is arranged on one end of the plate spring is hinged on the plate spring support, the plate spring support is fixed on a car frame, the other end of the plate spring is connected with one end of an oil-gas spring cylinder through a lower support and a spherical hinge, the other end of the oil-gas spring cylinder is connected onto an upper support through a spherical hinge, and the upper support is fixed on the car frame. The oil-gas suspension device for the trailer/semitrailer buffers through compressibility of the oil-gas spring cylinder, damps by controlling flow speed of oil liquid through a damping hole, replaces a steel plate spring or an air spring, and is applied on the trailer or the semitrailer, thereby achieving riding comfort and damping of cars, and prolonging life.
