The invention provides an ultra-lightweight balanced suspension, and belongs to the technical field of automotive suspensions.The ultra-lightweight balanced suspension comprises a cross beam (4), two balance-axle brackets (2) and a lower connecting plate (1) which are connected into a whole; the two ends of the cross beam (4) are fixedly connected with the upper portions of the balance-axle brackets (2) respectively, the two ends of the lower connecting plate (1) are connected with the bottom ends of the balance-axle brackets (2) respectively, V-shaped thrust rod installation seats (3) are arranged on the cross beam (4) in a front-and-back symmetric mode, and the outer sides of the balance-axle brackets (2) are each provided with a plate spring installation rack.According to the ultra-lightweight balanced suspension, by means of modular production and arrangement of the cross beam, the assembling accumulated error is greatly reduced, the production cost is reduced, the assembling work efficiency and assembling stability are improved, a good protection effect on a frame is achieved, stress deformation of the frame is reduced, all parts are mutually independent and are organically connected together through bolts, and maintenance and interchange of all the parts can be achieved.
