Abstract: In the mounting of working parts, especially the vehicle's axles, it is difficult to weld on the female threaded parts. To overcome this problem, the female threaded part is configured as an internally threaded stud. This stud is passed through a bore disposed in the lower flange of the beam. A flange fixedly attached to the stud is spot-welding to a cage whose walls are spot-welded to the upper and lower flanges of the beam. The welding procedure is thereby greatly simplified.

Abstract: In a body portion and frame assembly of a motor vehicle including a component assembly consisting of two longitudinally extending U-shaped profile members with outwardly directed spaced legs interconnected by transverse bottom and end panels which are welded to the U-shaped profile members, longitudinal frame members of the vehicle extend through the spaces between the spaced legs and are position-adjustable therein before they are welded to the legs of the U-shaped profile members thereby forming the body portion and frame member assembly with the frame members being accurately spaced from each other independently of tolerance deviations imparted by the transverse panels attached to the profile members.
