Definitions
- the invention relates to an electrically driven air pump, for example for Motor vehicles in which so-called secondary air is conveyed into the exhaust pipe system should be to improve the exhaust gas values.
- DE-A1 23 28 653 shows a method for joining plastic parts, in which a Partial seam surfaces swell with pure solvent, preferably without Filler, is provided. After kneading, hot kneading takes place e.g. B. by ultrasonic or friction welding, it being stated in the document that the supplied energy only has to be sufficient to knead the swollen seam parties and not to fuse the pure plastic.
- the invention has for its object to provide a method for producing Air pump with reduced vibrations or reduced running noise at which Leaks in joints are turned off, while also being a simplified Pump structure for large series production is to be achieved.
- FIG. 1 shows the air pump 1 according to the invention, consisting of a plastic Manufactured housing 2, which houses a pump unit 3 on the one hand and on the other hand an electric motor 4.
- the housing 1 is on the electric motor side by a cover 5 closed and has led out electrical connection cable 6 for the Electric motor 4.
- the pump station side is closed by a cover 7 which has an air supply connection 8.
- a stator 9 used, the guide channels 10, with which the a 1st impeller 11 air conveyed from the outer impeller outlet 12 in turn inner impeller inlet 13 of another impeller 14 is supplied. It goes without saying it goes without saying that a further stator 9 is used with each further pump stage.
- the housing 2 has in Area of the last impeller 14 on an annular channel 15, into which the air from the impeller 14 exits and is led to a pressure connection.
- the two wheels 11, 14 are attached with their hubs 16 to a shaft 17 of the electric motor 4, which in the pump station side protrudes.
- the electric motor 4 is in a recess 19 by means of a first elastomer ring 18 a housing wall 20 separating the pump station side from the electric motor side a second elastomer ring 21 held.
- the electric motor 4 with mounted pump impellers 11, 14 in installed condition, if the pump side is not yet closed by setting Balancing marks on the first impeller 11 is balanced, between the Impellers 11, 14, the stator 9 is arranged that radially, axially and non-rotatably in Housing 2 is held and during the cover assembly, the pump pressure levels from each other is sealed separately.
- a particularly simple version of an air pump manufactured using the method is given when the elastomer ring 21 between the electric motor 2 and cover 5 is clamped and a bulge 28 which is elastically deformable in the axial direction has, which is loaded by an axial surface 29 of a support ring 30 which with Clip projections 31 snap into corresponding recesses 32 in the housing 2.
- This version reduces running noise and simplifies installation under Elimination of individual parts.
