ABSTRACT:
Flap bearing mountings of the present invention are for mounting flap devices (5), such as switch-over, tumble, or swirl flap devices, on a housing (2) of an air intake port system (1) of a combustion engine. Mounting of flap devices (5) is accomplished by thermoforming projections (19) that are formed on bearing elements (10) of the flap device (5) and that extend through corresponding apertures (20) formed in the housing (2) of the air intake port system (1) of a combustion engine. This structure makes it possible to cost-effectively and precisely mount one-piece flap shafts (6, 7) in all air intake port systems (1), without having to use additional mounting elements. Through the exact, precise fixing of the mounted position, deformation of the shaft (6, 7), having flap bodies (8) arranged thereon, is reliably prevented and the service life of the entire flap device (5) is prolonged.
