Definitions

  • the present invention relates to a cooling system for motor vehicles with a radial pump trained cooling water pump and a thermostat for regulating the cooling, which is installed in a thermostat housing, the cooling water pump being a suction side Has housing which is integrally formed with the thermostat housing.
  • Such a cooling system should be as simple as possible own and be compact.
  • the simple structure enables an inexpensive production and the greatest possible reliability.
  • the compact structure is necessary because the installation space for ancillaries an increasing number of restrictions subject to.
  • a cooling system consists in its entirety of a cooling water pump, which is usually designed as a radial pump and the cooling water to the engine block and / or to the cylinder head of an internal combustion engine. From the engine block or Cylinder head leads a bypass line directly to a thermostat, while another line is also led to the thermostat via a cooler.
  • a heating heat exchanger provided that uses the heat of the cooling water in the interior to heat the air to be injected into the vehicle.
  • a thermostat In conventional cooling systems, a thermostat is occasionally arranged in the area of the cooler. Below a predetermined temperature, an expansion element blocks the Cooling water passage through the cooler, so that the cooling water only through the bypass line in the so-called small cycle. This enables a quick heating of the Engine after cold start. When the predetermined temperature is reached, the expansion element changes its length and clears the way of the cooling water through the radiator, so that proper engine cooling is achieved.
  • a thermostat is in the Area of the cooling water pump arranged.
  • the suction side and pressure side housing of the Cooling water pump consists of two separate components, and is for the thermostat at least a third component is provided.
  • Such cooling systems are functional satisfactory, but the manufacture and assembly is relatively complex.
  • WO 96/03574 describes a cooling system for an internal combustion engine known in which the cooling water pump and the thermostat arranged relatively compact are.
  • the flow to the thermostat is essentially frustoconical Housing, and the flow to the thermostat is essentially along its axis. It has it turned out that the response time with such a construction is relatively long. This means that the thermostat is closed during a cold start to keep the cooling water on Pass the cooler. With the engine warm, however, the thermostat should open to to ensure adequate cooling.
  • certain Operating conditions the cooling water reach its target temperature relatively quickly and exceed for a certain period of time until the thermostat opens. It can undesirable overheating.
  • the object of the present invention is to develop the cooling system described at the outset in such a way that that a simple and inexpensive production is possible and that a particularly simple structure is achieved. In particular, a quick response should be the thermostat.
  • this object is achieved in that on a connection part for the heating return is integrally formed a flow deflection bar, which partially the thermostat surrounds.
  • a holder for the thermostat is made in one piece with a bearing part is designed for the cooling water pump. Due to the inventive design of the Cooling system, the number of components can be reduced and it can be a special one compact and easy to manufacture cooling water pump thermostat unit shown become.
  • a pressure-side housing the cooling water pump is partly formed by the component that is the suction side Housing forms and the other part is formed by the bearing part, and especially when the sealing plane between the suction side housing and the bearing part the pressure side housing essentially divides along a middle plane.
  • connection part for a heating return is provided, which is attached to a flange on the thermostat housing is oriented essentially parallel to the axial direction of the thermostat. Of the Thereby the cooling medium flows directly from the heating return.
  • a flow deflection bar is in one piece is formed with a fastening part on which a connection part for a heating return can be fastened in two different orientations.
  • a position of the connector is particularly suitable for a longitudinal installation of the engine, while the another position is suitable for transverse installation.
  • a further significant simplification can be achieved if the suction side Housing formed as part of the engine block or the cylinder head of an internal combustion engine is. In this way, a further component can be omitted and the effort involved in Machining can be reduced because, for example, the cylinder head in any case for different other machining operations must be clamped.
  • the water pump thermostat unit of FIG. 1 consists of a first component 1, which is in one piece the suction-side housing 1a of the cooling water pump 2 and the thermostat housing 1b forms.
  • On the first component 1 is the bearing part 4 for the cooling water pump via a seal 3 2 flanged, which simultaneously forms the holder 4a for the thermostat 5.
  • a connection 6 on the bearing part 4 is for the return of the cooling water from the cooler, not shown intended.
  • a pump impeller 7 is placed on a pump shaft 8 in order to move from it Rotary motion to be offset.
  • the pressure-side space of the cooling water pump 2 is partial as a recess 9a in the bearing part 4 and the other part as a recess 9b in the first Component 1 is formed.
  • the thermostat 5 has an expansion element 10 which is mounted on a bracket 11 which is held by brackets 21.
  • a first spring 12 presses a first poppet valve 13 into the closed position.
  • a second spring 14 loads a second poppet valve 15 in the closing direction.
  • the springs 12 and 14 are designed as compression diaphragm springs.
  • the poppet valve 13 controls an opening through which cooling water from the radiator, not shown, to the cooling water pump 2 is returned.
  • the poppet valve 15 controls the bypass connection 16, via the Cooling water is returned directly from the engine block or cylinder head, not shown.
  • On a side flange 17 of component 1 is a connector 18 for the return of a heating heat exchanger, not shown, is provided.
  • a Flow deflection bracket 19 formed, which surrounds the thermostat 5.
  • the bracket 19 has the Task to redirect the cooling water that flows through the poppet valve 15 so that it Thermostat 5 flows safely. This ensures that the thermostat increases the temperature of the returning cooling water reacts quickly and reliably and when a predetermined temperature is exceeded, the poppet valve 15 closes. Training the flow deflection bracket 19 made of plastic allows a significant simplification of the manufacturing process for component 1 compared to one molded on it Rib. This can result in significant cost savings.
  • a seal 20 is provided to seal the connector 18 against the flange 17.
  • the flow deflection bracket 19 can be integrally formed with the connecting part 18, in An alternative embodiment variant can, however, provide that the flow deflection bracket 19 is formed on its own fastening part, which with the connecting part 18 in two different positions can be connected, for example via a dovetail guide. This makes it possible to use the connection part using the same components 18 in different positions, d. H. in a position in which the Connection part 18 shows in Fig. 2 to the left. as shown, or alternatively in one Position in which he points to the right.
  • the present invention enables an assembly consisting of a cooling water pump and thermostat, with few components and low manufacturing costs.
