The invention provides a Macphersan independent suspension assembly and belongs to the technical field of automotive suspensions. The Macphersan independent suspension assembly comprises a damper, a steering knuckle, a steering knuckle supporting pillar, a lower swing arm, a positioning steering pull rod and a supporting frame. The damper is fixedly arranged on the steering knuckle supporting pillar, the lower swing arm is arranged on the supporting frame, and the supporting frame is fixed to the steering knuckle supporting pillar. The first end of the positioning steering pull rod is connected with the supporting frame through a positioning hole, and the second end of the positioning steering pull rod is connected with the lower swing arm. The steering knuckle is arranged on the steering knuckle supporting pillar through a master pin, so that the phenomenon that the steering knuckle supporting pillar follows to rotate in the steering process of front wheels is avoided. By means of the method that the positioning steering pull rod limits the freedom degrees of the steering knuckle supporting pillar and the lower swing arm, the problem that a suspension assembly has too many freedom degrees is solved, and the advantages of a Macphersan front independent suspension are better brought into play.
