The invention relates to a railway goods traffic device, in particular to a sub-frame type radial bogie U-shaped sub-frame connection structure of a wagon, and belongs to the field of railway wagons and mechanical technology. A central spindle installation hole is formed in the end part of a radial connecting rod; an elastic hinge is arranged in the central spindle installation hole in a pressing way; a hinged hole is formed in a U-shaped sub-frame; the end part of the radial connecting rod with the elastic hinge is located in the hinged hole. The U-shaped sub-frame gapless elastic connection structure has the beneficial effects that with the elastic hinge, the elastic gapless hinge of the U-shaped sub-frame and three spatial directions of the radial connecting rod is realized, and the clearance and the abrasion of the radial connecting rod and the U-shaped sub-frame in various directions are eliminated.
