The invention belongs to the technical field of automotive rear bridges, and particularly relates to a double-shaft double-row shock-absorption rear-wheel driving bridge. The rear-wheel driving bridge comprises automobile body brackets, a first differential mechanism, a second differential mechanism, wheels, a second driving shaft, a first cardan, a first driving shaft, plate springs, bearing supports, a fourth driving shaft, a second cardan, a third driving shaft, rotary connection mechanisms, bearing rotation structures, rotating shafts and the like, wherein each automobile body bracket is mounted on the bearing rotation structure through the corresponding plate spring; each bearing rotation structure can rotate within a certain angle in the corresponding bearing support through a rotating joint; each of the two bearing supports is mounted between two wheels on one side. When the wheels come across a bulge of a certain height on a road surface, the bearing rotation structures can control the rise of the supporting point between two wheels on one side to be half of the height of the bulge; in addition, when any one of two wheels on each side is stressed on the bulge, the other wheel is also stressed, so that the instant force is distributed to the two wheels, and the reliability of the driving bridge is improved.
