Inlet manifolds such as intake manifolds, collector tanks, intake pipes, oscillatory intake passages, systems with variable-tract intake manifolds etc., for internal combustion engines operating on the principle of the diesel or Otto engine, where the inlet manifold includes two or more dish-shaped parts that are permanently joined to each other, and the dish-shaped parts are formed sheet parts, castings and/or extruded sections of metal. The permanent joining of the dish-shaped parts may be effected e.g. by adhesive bonding and/or welding.

Inlet manifold

Hollow bodies such as construction elements for vehicle manufacture can be produced by forming a preform in the form of a longitudinal body or sheets of aluminum or its alloys by means of a high internal pressure process or by superplastic forming in a tool. In this process the preform is heat treated locally before forming, on places of high elongation during the forming process and/or the tool for the forming process is equipped with local surface characteristics of different friction such as roughness patterns or with smoothed surfaces.

Process for manufacturing hollow bodies

A vehicle frame for powered vehicles with load-bearing sections and on these at least one housing for the upper end of a shock absorber; the housing is made of an extruded alloy, features a cover which is dished upwards, and is made up of a plurality of extruded shaped parts, each of which features shell-shaped sections which are curved in cross-section; projecting from the shell-shaped sections are at least two flange strips which serve as means for attachment to the neighbouring shaped part. The shaped part comprises shell-shaped sections each of which in cross-section is part of a circle and at the ends feature--as viewed in cross-section--flange strips running approximately radial to the central axis (B) of the housing.
