Welded intake device for an internal combustion engine

An intake device for an internal combustion engine, comprising welded shells joined along a partition line, in which the partition line is provided with a region for producing inclined additional surfaces, which generate a transverse force Q2due to their inclination relative to a pressure force D applied for welding the shells. This transverse force Q2offsets a transverse force Q1which is generated as a result of the inclination of partial regions of the partition line relative to the applied pressure force D. In this way, the transverse forces which arise during production of the intake device may be at least partially offset in the component, so that little or no forces are exerted on the molding tools, and the welding results for the intake pipe may thus be improved.

IMPROVED PERFORMANCE OF VIBRATION WELDED THERMOPLASTIC JOINTS

The invention provides an improved method of vibration welding of thermoplastic joints. Such welding is conducted by vibrating two fiber reinforced thermoplastic parts under pressure along their common interface to generate frictional heat to melt and fuse their surfaces together. Fibers from at least one surface penetrate both into the weld and into the other surface. As a result, the welded, fibre reinforced thermoplastic surfaces have increased tensile strength than heretofore achievable. Vibration welds of reinforced thermoplastic surfaces according to this invention achieve a maximum tensile strength as high as about 120 % of a weld formed by the unreinforced surfaces of corresponding thermoplastic materials.

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

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.

Intake pipe for an internal combustion engine comprising at least two welded shells

An intake pipe ( 10 ) for an internal combustion engine composed of shells ( 11 a, 11 b ) in which the geometry of the joining surfaces ( 19 ) adopts an approximately stepped course in areas with a slight incline relative to to joining force (F). This produces areas with a greater or lesser inclination relative to a joint line ( 16 ) indicating the average inclination 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 areas which are less inclined towards the joining force. This allows the shells ( 11 a, 11 b ) to have strongly curved joining surfaces, which increases the geometric design freedom of the intake pipe and, in particular, makes it possible to manufacture intake pipes with strongly curved intake channels constructed from just two shells.
