Abstract
A connecting tube for connecting two joint attachments of a steering or track rod. The connecting tube is reinforced by at least one tube section connected by friction force to the connecting tube such that either the entire outer or inside wall the tube section is in contact against a wall of the connecting tube, thereby forming a press fit connection. The steering or the track rod has a connecting tube with end sections that each hold or support components of joint attachments. A method for producing a connecting tube or the steering or the track rod in which first a tube semifabricate of the tube section is positioned within a tube semifabricate of the connecting tube and then the two tube semifabricates are expanded within a connection zone by a mandrel with an oversized section that is moved along the common axial direction of the two tube semifabricates.
