Definitions

  • the invention relates to a cooling water pump for an internal combustion engine with a flow guide housing, in which a pump impeller is arranged, and with a bearing part executed separately from the flow guide housing, which is a bearing for the pump impeller having.
  • Cooling water pumps of internal combustion engines are usually called radial or axial-radial pumps executed.
  • the flow guide housing of such pumps is generally a cast part made of aluminum or another metallic material.
  • a water pump is known from EP 0 208 074 A, in which individual parts are made of plastic are manufactured.
  • Such a water pump has the considerable advantage of being light and inexpensive to manufacture, and is generally lighter in weight than a water pump made of a metallic material.
  • the lower strength plastic leads to relatively serious design restrictions and difficulties in achieving the required lifespan.
  • greater tolerances between the pump impeller and the flow guide housing can be provided, which leads to a reduction in Efficiency and thus leads to an increase in the required drive power.
  • a coolant pump is known from WO 96/03574, in which a bearing part and a flow guide housing are designed as separate components. However, since the flow guide housing the forces acting on the bearing part must be dimensioned and The choice of materials places tight limits. The same applies to the one shown in EP-A 651 141 Solution.
  • the object of the present invention is to provide a cooling water pump with which it is possible to take advantage of using plastic materials with a simple Construction and a high degree of efficiency.
  • the flow guide housing between an anchoring part and the bearing part is arranged, and that the bearing part the flow guide housing engages and is attached to the anchoring part.
  • Essential to the present invention is that the relatively complex flow guide housing is simple and inexpensive can be manufactured.
  • this flow guide housing can Plastic, for example, be made by injection molding.
  • Serves as anchoring part For example, the engine block or the cylinder head of an internal combustion engine, on which the Cooling water pump is attached directly.
  • the cooling water supply is designed in this way the internal combustion engine is particularly simple.
  • the bearing part is directly connected to the anchoring part, is connected to the internal combustion engine or another fixed component, the pump impeller can be stored in a particularly rigid and stable manner.
  • the Bearing part can be designed as a simple cast part made of gray cast iron or cast aluminum can only be machined in a single setup on a lathe.
  • the flow guide housing With this construction, all that is required is for sealing Absorb forces. Considerable weight savings can therefore also be achieved.
  • the Flow guide housing has a first and a second sealing surface.
  • the first sealing surface lies sealingly on the anchoring part, while the second sealing surface lies on the bearing part fits tightly.
  • the first and second sealing surfaces are parallel to each other be formed on opposite sides of the flow guide housing. To this A separate attachment of the flow guide housing is not necessary as this is held between the anchoring part and the bearing part.
  • grooves for receiving sealing elements are located in the flow guide housing for sealing against the anchoring part and / or the bearing part are provided. This enables a further simplification in the manufacture.
  • the cooling water pump according to the invention consists of a flow guide housing 1, the one has first sealing surface 2 and a second sealing surface 3.
  • the second sealing surface 3 is in the axonometric representation not visible.
  • the first sealing surface 2 is provided for to lie tightly against the cylinder block of an internal combustion engine, not shown.
  • To a groove 4 is formed in the sealing surface 2, which receives a seal 5.
  • the first sealing surface 2 encloses an opening 6, which in the assembled state has a direct flow connection forms the cooling water pump with the water jacket of the internal combustion engine.
  • a pump impeller 7 is arranged in the flow guide housing 1 and is mounted on a shaft 8 is attached.
  • a plain bearing body 9, which is connected to the shaft 8, is rotatable in one Bearing part 10 stored.
  • the bearing part 10 has four mounting legs 11, 12, 13 and 14, which in when assembled, encompass the flow guide housing 1.
  • About screws 15 is the bearing part 10 to attach to the internal combustion engine, not shown.
  • An O-ring seal 16 seals the flow guide housing 1
  • a V-belt pulley 18 is located on a shaft stub 17 opposite the shaft 8 attached to drive the cooling water pump according to the invention.
  • a fastening part 19 with a nut 20 are used to fasten the V-belt pulley 18 to the stub shaft 17.
  • thermostat housing 21 is also attached in one piece to the flow guide housing 1, which receives a thermostat 22.
  • a cover 23 closes the thermostat housing 21.
  • Sealing rings 24 and 25 serve to seal the connections or the components described above among themselves.
  • a mechanical seal 26 is used to seal against the outside.
