  • the rectangular, tinned copper is pressed around the rod-shaped aluminum.
  • the starting material is delivered in poles.
  • To make a grounding lug it is cut to size, drilled, mechanically machined and deburred all around. In this case, a residue-free mechanical processing is necessary because copper residues on aluminum can lead to increased corrosion.
  • the object of the invention is to reduce the manufacturing cost of such grounding straps.
  • a railway vehicle according to the invention in particular passenger transport, comprises an aluminum shell construction and cable lugs attached to the aluminum shell according to the invention, in particular of copper, as ground lugs.
  • the aluminum shell has correspondingly shaped conductors which are attached to the aluminum shell or are formed without joints from the aluminum shell.
  • the conductor is made of aluminum or an aluminum alloy.
  • the cable lug is made of copper or a copper alloy.
  • the cable lug and the conductor are joined together, in particular welded, wherein the joint connection, or the welded joint, by means of electromagnetic pulse forming technology is available.
  • the earthing strap is produced by inserting the conductor into a conductor receptacle of the cable lug and then welding it to the cable lug, in particular with its conductor receptacle, by means of electromagnetic pulse-forming technology. It can be adapted by mechanical deformation of the inner contour of the conductor receiving a inserted into the conductor receptacle of the cable lug end of the conductor before insertion into the conductor receiving the lug, for example, be flattened to be complementary to this, in particular so that the inner cross section of Conductor receptacle and the outer cross section of the conductor undergo a transition fit to fit the conductor in a conductor receptacle of the cable lug.
