The utility model provides a balanced linkage, includes: two V type distance rods, its setting that assumes diamond in shape each other, on the outside of V type distance rod end was fixed in the traction bar support in the axle, its medial extremity passed through joint bearing and utilizes I articulated the installation on V pole support on the bolt, and V pole support is fixed in on the solebar through bolt II and nut I, and two be distance rod under the splayed mechanism, and the head is correct each other sets up for it, and on the outside end hinge of lower distance rod met the lower traction bar support who installs in the axle, it is epaxial that its medial extremity passes through II articulated balances of installing on the frame on bolt III and the nut. Lower distance rod through V type distance rod and splayed is connected with the axle, and the movement track of axle is fixed up promptly, and V type distance rod utilizes the triangle -shaped structure, and fixed the axle horizontal position, distance rod bilateral symmetry arranges down simultaneously, is the splayed structure, further improves suspension system lateral stability, and manufacturing process is simple, and is rational in infrastructure, improves with low costsly.
