Abstract

Disclosed is a flap bearing arrangement ( 10 ), having a bearing mount ( 20 ) with two side parts ( 24 ) connected by means of a tube section ( 22 ), between which is arranged an O-ring ( 30 ) which surrounds the tube section ( 22 ). Also disclosed is a flap bearing arrangement ( 100 ) for an intake device ( 200 ) having a flap shaft ( 100 ).

First claim

What is claimed is:

1 . A flap bearing arrangement, comprising:
a bearing mount having two side parts, the two side parts spaced apart from each other; a tube section extending between and connecting the two side parts, a direction of extension of the tube section defining an axial direction; an O-ring circumferentially surrounding the tube section, the O-ring arranged between the two side parts.

2 . The flap bearing arrangement according claim 1 , wherein
the two side parts each have a substantially rectangular cross-section perpendicular to the tube section extending between and connecting the two side parts.

3 . The flap bearing arrangement according to claim 2 , wherein
the two side parts each have a radially outer circumference, where radial relative to the tube section connecting the two side parts; wherein the O-ring projects radially only sectionally beyond the outer circumference of the two side parts.

4 . The flap bearing arrangement according to claim 3 , wherein
the O-ring projects radially outwardly beyond the outer circumference of the two side parts by no more than 50% of an outer diameter of the O-ring.

5 . The flap bearing arrangement according to claim 1 , wherein
a cylinder support is arranged on an outer side of each of the two side parts; wherein the cylinder support projects outward axially, an axial direction relative to the tube section extending axially between and connecting the two side parts.

6 . The flap bearing arrangement according to claim 1 , wherein
the bearing mount is formed from polyphenylene sulfide.

7 . The flap bearing arrangement according to claim 1 , wherein
the O-ring is an elastomer.

8 . A flap shaft assembly, comprising:
an elongated flap shaft, wherein a direction of elongation of the flap shaft defines an axial direction; a plurality of flap bearing arrangements, each including:
two side parts, the two side parts spaced apart from each other;
a tube section extending between and connecting the two side parts, the tube section extending in the axial direction;
an O-ring circumferentially surrounding the tube section, the O-ring arranged between the two side parts;
wherein each of the plurality of flap bearing arrangements are spaced apart axially on the elongated flap shaft.

9 . An air intake device for an internal combustion engine, the air intake device comprising:
a flap shaft assembly according to claim 8 .

10 . The air intake device according to claim 9 , wherein
the flap shaft assembly is arranged between an upper part and a lower part of the air intake device; wherein the upper and lower parts are securely welded to each other.
