Definitions

  • the invention relates to an electrically driven air pump, for example for motor vehicles, in which so-called secondary air is to be conveyed into the exhaust pipe system in order to improve the exhaust gas values.
  • the invention has for its object to provide an air pump with reduced vibrations or reduced running noise, in which leaks in joints are eliminated, in addition, a simplified pump structure is to be achieved.
  • FIG. 1 shows the air pump 1 according to the invention, consisting of a housing 2 made of plastic, which houses a pump unit 3 on the one hand and an electric motor 4 on the other hand.
  • the housing 1 is closed on the electric motor side by a cover 5 and has electrical connection cables 6 for the electric motor 4 on.
  • the pump station side is closed by a cover 7 which has an air supply connection 8.
  • a stator 9 is inserted between the cover 7 and the housing 2, said stator having guide ducts 10 with which the air conveyed by a first impeller 11 is in turn fed from the outer impeller outlet 12 to the inner impeller inlet 13 of another impeller 14. 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 exits the impeller 14 and is led to a pressure connection.
  • the two impellers 11, 14 are fastened with their hubs 16 to a shaft 17 of the electric motor 4, which projects into the pump unit side.
  • the electric motor 4 is held by means of a first elastomer ring 18 in a recess 19 of a housing wall 20 separating the pump station side from the electric motor side and a second elastomer ring 21.
  • the electric motor 4 with mounted pump impellers 11, 14 in the installed state, with the pump side not yet closed, is balanced by setting balancing marks on the first impeller 11, the stator 9 being arranged between the impellers 11, 14, that radially , is axially and non-rotatably held in the housing 2 and is sealed in the cover assembly, the pump pressure stages separating one another.
  • the cover 7, the stator 9 and the housing 2 are made of plastic and are connected and sealed by friction welding, with an elastic / plastic deformation of one another when the components are joined together before the friction welding in the welding zones 22, 23
  • Contacting walls of the cover 7, the stator 9 and the housing 2 is present, as shown in Figure 2, which shows an enlarged detail of Figure 1.
  • this eliminates the need for components, seals and screws, the welding zones 22, 23 ensuring absolute tightness.
  • a particularly simple embodiment according to the invention is provided if the elastomer ring 21 between the electric motor 2 and the cover 5 has a bulge 28 which is elastically deformable in the axial direction and which is loaded by an axial surface 29 of a support ring 30, which has clip projections 31 in corresponding recesses 32 in the housing 2 snap into place.
  • This version reduces running noise and simplifies assembly, eliminating individual parts.
