The invention relates to the field of transmission shafts of power systems of vehicles, in particular to a compensation type middle supporting device of a two-section vehicle. The device comprises aninner spline shaft and an outer spline flange shaft, and the outer spline flange shaft is arranged in the inner spline shaft and can move along the axis of the inner spline shaft. A supporting shell is further included, and the internal spline shaft is arranged in the supporting shell and can rotate in the supporting shell; a cavity is formed between the inner spline shaft and the supporting shelland filled with lubricating oil; and an oil seal is further arranged between the inner spline shaft and the supporting shell and used for sealing the cavity. The device has an axial compensation function, and the obstacle crossing capacity and flexibility of the vehicle can be improved.
