Definitions

  • the invention relates to an oil pan for a motor and / or a transmission, with a trough-shaped collecting portion having a bottom-side opening which is closed by a lid.
  • An oil pan of the type mentioned is known from DE 38 30 966 Cl.
  • oil which is required for the lubrication of the moving parts of the engine and / or the transmission, collected and fed via an oil suction pipe back to the cooling circuit.
  • an oil cooler available, through which the oil is cooled.
  • an oil pan is known, which is partially double-walled, wherein flows through the cavity between the two walls, a coolant. As a result, a heat exchanger is formed, which transfers heat from the oil into the coolant.
  • Object of the present invention is to develop an oil pan of the type mentioned so that they can be produced as inexpensively. At the same time, the integration of the heat exchanger and the oil pan into the engine or transmission should be simplified.
  • the cover comprises a heat exchanger for the oil, which has a coolant inlet, a coolant outlet, and fluidly intervening coolant channels.
  • the heat exchanger By integrating the heat exchanger in the lid of the collection section remains free of heat exchanger elements, which makes its production easier and cheaper. At the same time, space is saved in the area of the engine since the heat exchanger is arranged outside the engine on the oil sump. Furthermore, the production of the heat exchanger itself is simplified, since the lid is generally a generally flat and flat part, which thus has simple geometric shapes. In addition, the lid according to the oil pan can be comparatively large, which allows the production of a large and powerful heat exchanger. Finally, the lid is usually located in the region of the lowest point of the oil pan, from which the oil again is sucked into the cooling circuit. By having there the heat exchanger, the oil is cooled immediately before the re-feeding into the cooling circuit, which is thermally favorable for the engine.
  • the coolant inlet or the coolant outlet is designed as a pipe socket which is inserted into a corresponding connection opening in the collecting section. This is a first advantageous possibility with which the coolant connections are automatically produced during assembly of the cover to the collecting section.
  • the design of the coolant inlet and / or the coolant outlet as a pipe socket allows a comparatively low precision in the production, since the seal between the heat exchanger and the collecting section can be made by radially acting seals on the pipe socket.
  • the coolant inlet or the coolant outlet is designed as a pipe socket, which is inserted through a recess in the collecting section.
  • the coolant circuit of the heat exchanger is not connected to the collecting section at all.
  • the pipe sockets provide their own and separate from the collection section through pipes, through which the coolant is passed through the collecting section therethrough. This results in a particularly good sealing of the coolant circuit with respect to the oil circuit guaranteed.
  • the recess protects the pipe socket from damage. It should be noted that the recess does not have to be closed on all sides to fulfill this function.
  • a further alternative may be that at least either the coolant inlet or the coolant outlet is formed as a flat opening on the side of the lid facing the collecting portion, at the edge region of which a connecting portion bears in an axially sealing manner a coolant channel formed in the collecting portion. Also in this design manufacturing tolerances are compensated in a simple manner, which reduces the total manufacturing and assembly costs.
  • the oil sump according to the invention in which the pipe socket and the connection opening and / or the pipe socket and the recess and / or the flat opening and the connecting portion are arranged outside a seal between the lid and the collecting portion / is.
  • a double seal of the coolant circuit is created with respect to the oil circuit, which improves the reliability of the oil pan according to the invention.
  • a particularly good efficiency of the heat exchanger can be achieved if the heat exchanger has an oil inlet, an oil outlet, and fluidly intervening oil channels.
  • the oil outlet is designed as an oil suction tube, which is inserted through a recess in the collecting section.
  • the assembly of the cover or the heat exchanger is further simplified at the collecting section, and it is ensured that the cooled oil does not mix with the oil accumulated within the collecting section.
  • the oil outlet may be formed as an oil suction pipe, which is inserted into a corresponding connection opening in the collecting section.
  • the cover with the heat exchanger has a smaller overall size and is therefore easier to handle.
  • the connection opening in the collecting section can be assigned an oil suction channel, which enables optimum oil guidance for the respective installation situation.
  • the oil outlet can also be designed as a flat opening in the side of the cover facing the collecting section, at the edge region of which a connection section of an oil channel formed in the collecting section rests in an axially sealing manner.
  • the oil inlet of the heat exchanger can be designed as a flat suction opening in the side of the lid facing the collecting section. This is particularly inexpensive to produce.
  • a filter device In the region of the oil inlet, a filter device can be arranged which is preferably integral with the heat exchanger or the cover. As a result, impurities of the oil are filtered out and kept away from the oil pump. Their life is thereby extended.
  • a further advantageous embodiment of the oil sump according to the invention provides that are arranged on the collecting section facing side of the lid and / or on the collecting oil guide ribs, which guide oil present in the oil pan to the oil inlet present in the lid. This prevents dead zones forming within the collecting section in which oil is present which does not reach the heat exchanger.
  • the heat exchanger made of metal, preferably of aluminum, and the collecting section are made as a plastic injection molded part.
  • a heat exchanger is very stable and has a high efficiency, whereas a collecting section produced in the said manner is inexpensive.
  • the seal between plastic and metal can be reliably and easily realized.
  • the lid has lamellae and / or ribs on its side facing away from the collecting section.
  • the cover or the heat exchanger is stabilized and protected, for example, from falling rocks.
  • the heat exchanger can be cooled by the slats themselves, which increases its efficiency.
  • the maintenance of the engine or of the transmission is simplified when a closable opening for the oil and / or a closable opening for the coolant is present at a fluidically in the horizontal position of use fluid deepest point of the heat exchanger, because this ensures that, if necessary, the entire oil and / or all the coolant can be drained.
  • the cover can normally be removed from the collecting section of the oil sump, the sensor is easily accessible when the sensor is attached to or in the heat exchanger.
  • the sealing takes place on at least one interface between the cover and the collecting section through a seal with activatable self-expansion.
  • activation can be done for example by applying heat, and it leads to a secure seal even on inaccessible areas of the oil pan.

Also, the oil outlet 40 is formed as such a flat opening on the collecting section 16 facing side 46 of the flange plate 22.
