Embodiment Construction

[0023] exist figure 1 The axle body described in comprises a total of three longitudinal sections, which is here designed as a continuous axle body for a non-driven commercial vehicle axle. The shaft tube 1 made of steel forms the central longitudinal section. A journal 2 is fastened on each of the two open ends of the axle tube 1 by means of the welding method described in more detail below. Each journal 2 is preferably made of steel and is provided with a bearing surface 3 for a bearing component, for example a roller bearing for the corresponding wheel and / or for supporting a brake drum or a brake disc of a disc brake. Furthermore, a brake carrier of a drum brake or a disk brake can be fastened to the journal 2 .

[0024] The shaft tube 1 obtains its length by sawing. The kerf extends perpendicularly to the longitudinal extent of the shaft tube. This results in a sawn joint surface, which is suitable for the subsequent welding process without further processing.

Abstract

The invention proposes a method for producing an axle shaft by materially joining an axle tube to a journal, which is provided with a bearing surface for supporting a wheel and has a tube cross section facing the axle tube. The method comprises the steps of arranging the shaft tube and the shaft journal with their joint surfaces of the tube cross-sections arranged coaxially opposite each other in the workpiece receptacle of a welding assembly, which also includes an arc welding device and a laser operating in parallel Welding device; continuous drawing of the weld seam in the circumferential direction of the tube cross-section, both welding devices are actively and from the outside aligned on substantially the same circumferential section of the joint surface, and the laser beam is directed perpendicularly on the outside of the tube And intersecting the longitudinal axis of the shaft tube, wherein the zero-gap sensor is used to guide or position the welding process; after the weld seam has been guided through a circumferential angle of at least 360°, the pulling of the weld seam is ended. Furthermore, the invention proposes a corresponding axle shaft.

Description

technical field [0001] The invention relates to a method for producing an axle shaft by materially connecting an axle tube with a journal arranged on the longitudinal axis of the axle tube, said journal being provided with a bearing surface for supporting a wheel and facing The shaft tube has a tube cross section which is substantially equal to the tube cross section of the shaft tube. [0002] The invention also relates to an axle shaft, preferably producible by such a method, comprising an axle tube and a journal provided with a bearing surface for supporting the respective wheel, said journal facing the axle tube having a tube cross-section, This tube cross-section is substantially equal to the tube cross-section of the shaft tube, and the two tube cross-sections lie opposite each other and are bonded to one another via a weld seam. Background technique [0003] A shaft body produced by welding is described in one possible embodiment in EP 2 133 164 B1. On the central a...
