SUCTION PIPE FOR AN INTERNAL COMBUSTION ENGINE, COMPRISING AT LEAST TWO WELDED SHELLS

摘要

The invention relates to a suction pipe (10) which has shells (11a, b). The invention provides that the geometry of the joining surfaces (19) adopts an approximately stepped course in areas with a slight incline, in relation to the joining force (F). This produces areas with a greater or lesser incline in relation to a joining line (16) indicating the average gradient of the joining surfaces. This results in areas which can be welded with a high degree of stability because of their considerable incline towards the joining force. These areas can then support those areas which are less inclined towards the joining force. This allows the shells (11a, b) to have strongly curved joining surfaces, which increases the geometrical structural freedom for the suction pipe. In particular, it is possible to produce suction pipes with strongly curved suction channels, constructed from just two shells.
