Abstract: A process and device are disclosed for connecting stacked vehicle body elements of a light alloy using stamped rivets. Using the disclosed process and device, damaged vehicular body elements may be easily removed and replaced. A first body element and damaged second body element attached thereto by means of stamped rivets are separated and the damaged second body element replaced by a third body element. Process steps include forcing out an old stamped rivet, restoring a stamped rivet area on a first body element, placing a third body element in position, and punching and riveting the third body element and the first body element. A device related to the disclosed process includes pneumatically compressible tong arms for holding tool inserts. A variety of tool inserts are adapted for forcing out an old rivet, restoring stamped area in the first body element and punching hole and stamping a countersink in the third body element.

Abstract: A bearer joint for a vehicle bodywork, and in particular a longitudinal front bearer joint, and a method for placing a aluminum bearer member on the bearer joint in the vehicle bodywork. The bearer joint comprises a cast aluminum connector for joining together a first forward bearer member and a second rearward bearer member. The connector includes a tubular aluminum recess or socket for receiving the rearward end of the first aluminum bearer member which is fixed thereto by a transverse weld seam at the front receiving edge of the socket. A plurality of offset thickened regions with through holes are provided to the periphery of the socket. To replace a damaged front bearer member, the weld is cut and the damaged front bearer is withdrawn from the socket. A repair kit is provided which includes a replacement front bearer member and a platelike insert sized to fit within an end of the replacement bearer member.

Abstract: A method for repairing a damaged sill member of a vehicle bodywork, wherein the sill member is formed as an extruded hollow section member which is disposed connected between two cast light-metal node elements. A damaged girder portion of an extruded hollow section sill member is severed at a distance from each node element, and is removed. A girder stub portion of the original hollow section sill member remains attached to each node element. Short sleeve inserts are slidably inserted into the open ends of each of the girder stub portions such that a portion of a sleeve insert extends into an associated stub portion and another portion of the sleeve insert projects out of the associated stub portion. A replacement girder portion is inserted between the open ends of the girder stub portions.
