Providing an interlocking recess in a tubular axle body of a vehicle axle

A method for manufacturing a wheel axle of a utility vehicle such as a trailer, semi-trailer or a truck, wherein the wheel axle comprises a hollow axle body comprising a steel tubular wall having a thickness t and having a clamping region adapted to be clamped in use between clamping parts of the vehicle suspension by means of tensioning means. An interlocking recess is formed in the clamping region. The interlocking recess is formed by a forming process wherein a stamp member is pressed into the outer surface of the tubular wall so as to form an indent. The dimension of the stamp and the pressing force are such that the surface pressure on the stamped surface portion of the tubular wall locally exceeds the yield point to form the indent and the pressing force is such that the tubular wall portion adjacent the interlocking recess is plastically sagging over a distance inwards which is at most corresponding to the thickness t of the tubular wall. Preferably the sagging distance inwards is within a range of 0 to 0,5 times the thickness t of the tubular wall. In an alternative method the interlocking recess is formed by friction drilling a blind hole in the tubular wall of the axle body.
