Definitions

  • the invention relates to an oil pan for an engine and / or a transmission, with a trough-shaped Collecting section with a bottom opening through a lid is closed.
  • An oil pan of the type mentioned is from the DE 38 30 966 Cl known. In it becomes oil, which for the Lubrication of the moving parts of the engine and / or the Gearbox is required, collected and over ⁇ lansaugrohr returned to the cooling circuit. At a Oil pan of this known type is outside of the oil pan an oil cooler exists, through which the oil is cooled. From DE 31 42 327 Al an oil pan is known which partially double-walled, being through the cavity a coolant flows between the two walls. hereby a heat exchanger is formed, which heat from the oil transfers to the coolant.
  • Object of the present invention is to provide an oil pan of educate the aforementioned type so that they can be produced as inexpensively as possible. simultaneously intended the integration of the heat exchanger and the sump in the engine or the transmission can be simplified.
  • the cover is a heat exchanger for the oil comprising a coolant inlet, a Coolant outlet, and fluidly intervening Has coolant channels.
  • the collecting section remains free of heat exchanger elements, which makes its manufacture easier and cheaper. At the same time, space is saved in the area of the engine since the heat exchanger outside the engine on the oil sump is arranged. Furthermore, the production of the Heat exchanger itself simplified, since the lid in the Is a generally flat and flat part, which therefore has simple geometric shapes. In addition, the lid according to the oil pan be comparatively large, making the production of a large and powerful heat exchanger allows. After all the lid is usually in the area of the deepest Point of the oil pan arranged, from which the oil again is sucked into the cooling circuit. By there the Heat exchanger is present, the oil is immediately before the re-feeding into the cooling circuit cooled what for the engine is thermally favorable.
  • the coolant inlet or the coolant outlet is designed as a pipe socket which passes through a recess inserted in the collection section.
  • the coolant circuit of the heat exchanger at all not connected to the collection section.
  • the pipe sockets offer their own and from the collection section separate passageways through which the coolant passed through the collection section. hereby will be a very good seal 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 this To fulfill function.
  • a second alternative may be that at least either the coolant inlet or the Coolant outlet as a flat opening on the Formed collecting portion facing side of the lid is, at the edge region of a connection section a in Collection section formed coolant channel axially sealingly rests. Also in this construction Manufacturing tolerances in a simple manner balanced, resulting in a total of manufacturing and assembly costs lowers.
  • the oil pan 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 connection section outside one Seal between the lid and the collecting section are arranged / is.
  • This will be a double Sealing the coolant circuit with respect to Created oil circulation, which is the reliability of the improved oil pan according to the invention.
  • a particularly good efficiency of the heat exchanger can when the heat exchanger has an oil inlet, an oil outlet, and fluidly intervening oil passages having.
  • the Oil outlet is designed as an oil suction, which by a recess is inserted through the collection section.
  • the oil outlet as ⁇ lsaugrohr be formed, which in a corresponding Connection opening is inserted in the collection section.
  • the cover with the heat exchanger has a total a smaller size and therefore easier to handle.
  • the connection opening in the collecting section be associated with an oil suction, which is one of the respective Installation situation enables optimal oil routing.
  • the oil outlet also as a shallow opening in the Formed collecting portion facing side of the lid be at the edge region of a connecting portion of an im Sealing portion formed oil passage axially sealing is applied. This is a simple tolerance compensation possible with simultaneous reliable sealing.
  • the oil inlet of the heat exchanger can be considered flat Intake opening in the collection section to the side facing be formed of the lid. This is very cheap manufacture.
  • a filter device In the area of the oil inlet can be a filter device be arranged, which preferably integrally with the Heat exchanger or the lid is. This will be Impurities of the oil filtered out and from the Oil pump kept away. Their life is thereby extended.
  • a further advantageous embodiment of According to the invention sump provides that on the Collection section facing side of the lid and / or on Collection section oil guide ribs are arranged in the oil pan existing oil to the existing in the lid Guide oil inlet. This prevents being within the Collective section form dead zones where oil is present is, which does not get to the heat exchanger.
  • the heat exchanger Metal preferably of aluminum
  • the collection section are manufactured as plastic injection molded part.
  • Such a Heat exchanger is very stable and has a high Efficiency, whereas one in the said way manufactured collection section is inexpensive. Furthermore Can the seal between plastic and metal be realized reliably and easily.
  • the lid on its side facing away from the collecting section slats and / or having ribs. This will make the lid or the heat exchanger stabilized and for example, protected against stone chipping. On the other hand the heat exchangers are cooled by the fins themselves, which increases its efficiency.
  • the gearbox For safe operation of the engine and / or the gearbox contributes, if at and / or in the heat exchanger at least a sensor is arranged, which is an operating quantity of the oil and / or the coolant detected. Since the lid is in Normally removed from the collection section of the oil sump is, when attaching the sensor to or in the heat exchanger the sensor easily accessible.
  • the seal on at least an interface between the lid and collecting section through a seal with activatable self-expansion he follows.
  • Such activation can, for example, by heat is applied and it leads to a secure seal even on the outside inaccessible Place the oil pan.
  • a motor carries the reference numeral 10, a to the Engine 10 flanged transmission, the reference numeral 12, and an oil pan connected to engine 10 and transmission 12 Reference numeral 14.
  • the oil pan comprises a trough-shaped Collecting section 16 with a bottom-side opening 18th This is generally in the lowest range Position of the oil pan 14.

Also, the oil outlet 40 is as such a flat opening on the Collection section 16 facing side 46 of the flange plate 22 formed. As is apparent from FIGS. 2, 4, and 5, are in the collecting section 16 coolant channels 48 and 50 as well an oil passage 52 is formed. These white to the engine 10 out Connecting pieces 54, 56, and 58, with which the Connections to the coolant pump 36 and to the oil pump 44 will be produced.
  • the channels 48, 50, and 52 open towards the lid 20 in Terminal sections 60, 62, and 64, which, as an example in Figure 5 for the connection portion 60 for the Coolant inlet 30 is shown at the top 46th the flange plate 22 of the lid 20 abut.
  • the Sealing of the respective joints is done by axially acting sealing rings 66, 68, and 70.
  • the latter include a self-expanding component upon activation. The Activation can be by applying a temperature respectively.
  • Oil guide ribs 76 are arranged in the oil pan 14th existing oil to the top 46 of the Grease flange 22 existing oil inlet 38. By the Oil guide ribs 76 also becomes the collecting section 16 in particular in the region of the bottom-side opening 18 stiffened. From Figures 2 and 3 is beyond it can be seen that the lid 20, and here in particular the Heat exchanger 24, on its of the collecting section 16th side facing away from slats 78, through which the Heat exchanger 24 is cooled itself.
