Definitions

  • the invention is based on an oil pan arrangement for a machine, in particular an internal combustion engine and / or a transmission, with a machine housing and a trough-shaped collecting section for the oil, which adjoins at least one region of the machine housing.
  • Oil pan assemblies of the type mentioned are known from DE 101 19 937 A1 and DE 101 24 071 A1.
  • oil pans disclosed there are attached to the underside of a crankcase and a gear housing flanged to the crankcase. While the crankcase and the transmission housing are made of steel, the oil pan is a plastic injection molded part.
  • the present invention has the object, an oil pan assembly of the type mentioned in such a way that it has the longest possible life.
  • An advantageous embodiment of the oil pan arrangement according to the invention provides that the first area of the machine housing is a crankcase area of an internal combustion engine and the second area of the engine compartment Machine housing is a housing portion of a transmission. Above all, the vibrations generated by a transmission can load the collecting section very heavily. In such an oil pan arrangement, therefore, the advantages of the invention are particularly strong.
  • the first area of the machine housing also adjoins the collecting section.
  • the loads of the collecting section would be particularly large. Due to the frictional connection of the two areas of the machine housing by means of the force receiving element lying between these two areas collection section is particularly clear. In this case, the force receiving element extends in most cases through the collecting portion or past this, which is basically possible in the other embodiments of the invention.
  • the first region of the machine housing is a mounting flange of a crankcase. This is particularly well suited for the support, since it is designed to be relatively stiff anyway.
  • the force receiving element rigidly connected to at least one of the two areas of the machine housing, preferably screwed.
  • vibrations are damped particularly effective.
  • bending loads or shear forces transmitting force-receiving element can be designed so that it affects the functionally required shape of the collection section as little as possible.
  • the oil pan arrangement comprises a fastening flange integrally formed on the collecting section, which in the installation position is clamped at least in regions between the force receiving element and the corresponding region of the machine housing.
  • the connection of the collecting section to the machine housing is also used for the attachment of the force receiving element and the introduction of force into this, which reduces the manufacturing and assembly costs.
  • a stiff, yet lightweight embodiment of the force receiving element provides that it has at least one recess. Such recesses may for example be present between stiffening ribs.
  • Particularly suitable materials for the force receiving element are steel, aluminum, or carbon fiber composite. The production of a carbon fiber composite (or a composite with another high-strength and temperature-resistant fiber) allows a very goal-oriented design of the force receiving element.
  • the force receiving member may be supported by the collecting portion.
  • the collecting portion In order to facilitate the assembly of the oil pan assembly, the force receiving member may be supported by the collecting portion.
  • at least one region of the force-receiving element is received in a recess in the collecting section. This leads to a particularly secure mounting of the force receiving element through the collecting section, which significantly simplifies the assembly of the oil pan arrangement.
  • the oil pan arrangement of the connection of the force receiving element with the to the collecting section adjacent second region of the machine housing are chosen so that the collecting section is optimally relieved.
  • a further particularly advantageous embodiment of the oil pan arrangement according to the invention provides that a decoupling layer is present between the rod-shaped force receiving element and the collecting section. This ensures that only comparatively small loads are transmitted to the collecting section of the force-absorbing element held by the collecting section during operation of the oil pan arrangement.
  • a decoupling layer ensures that the transmission of vibrations from the force-receiving element in the collecting section is reduced. This decoupling layer therefore has an even longer life of the collecting section result, while easy installation.
  • the decoupling layer comprises a rubber and / or plastic and / or Teflon material.
  • the force receiving element may be connected at least in one area with the machine housing by plugging and / or clamping and / or screwing.
  • the at least a force-receiving element projects in the installed position down over the collecting portion at least partially.
  • the collecting portion is usually formed as a thin-walled plastic injection molded part, which itself has only a low strength.
  • the protrusion of the force-receiving element prevents impermissible forces from being introduced into the collecting section as a result of a direct contact of the collecting section with a surface below the collecting section, for example the floor of a workshop. In this way, therefore, the collecting section from damage, for example, in an expansion of the internal combustion engine and a settling on a workshop floor, protected.
  • the collecting section is made of aluminum and has a certain inherent rigidity. In this case, by the supernatant at a contact of the internal combustion engine with a substrate, eg. A workshop floor, an impermissible force into a seal, which seals the oil pan relative to the machine housing, prevented.
  • the force receiving element is formed and / or connected to the machine housing, that it transmits essentially only forces in its longitudinal direction (push / pull rod).
  • the force receiving element can have a comparatively small cross-section and can be so small overall that it can easily be integrated into a small oil pan arrangement.
  • the transmission of forces in its longitudinal direction ensures a noticeable stabilization of the area adjacent to the collecting portion of the machine housing and a corresponding reduction of loads introduced into the collection section.
  • a first embodiment of an oil pan assembly carries in the figures 1 and 2 in total the reference numeral 10. It includes in the present embodiment, an oil pan 12 with a trough-shaped Collecting section 14. This is about a circumferential flange 16 attached to a portion 18 of the crankcase 20 of an internal combustion engine 22. To the crankcase 20, a transmission housing 24 of a transmission 26 is flanged laterally. Crankcase 20 and gearbox housing 24 form a total of a machine housing 20, 24 of the oil pan assembly 10th
  • the gearbox housing 24 is arranged vertically offset slightly downwards relative to the crankcase 20 (cf., FIG. 2). This allows the oil pan 12 to be associated not only with the crankcase 20 but also with the transmission housing 24.
  • the collecting portion 14 of the oil pan 12 is laterally connected via a flange 28 with a directly adjacent to the oil pan 12 region 30 of the gear housing 24.
  • the crankcase 20 and the transmission housing 24 are steel or aluminum parts.
  • the collecting portion 14 of the oil pan 12 is made of plastic by means of an injection molding process.
  • vibrations of the crankcase 20 and the Transmission housing 24 are transmitted via the flanges 16 and 28 as dynamic loads in the oil pan 12 and the collecting section 14.
  • four force receiving elements 32a to 32d provided. These are pipes made from a steel material, by which, in particular, the area 30 of the gear housing 24 which is directly adjacent to the oil pan 12 and which is particularly critical in terms of vibration technology, is stabilized.
  • the force receiving elements comprise unidirectional carbon fibers. It is also possible to integrate the carbon fibers as stringer in the production of the wall of the collection section 14.
  • the force-receiving elements 32 are connected at their one ends via bearings 34, which are shown only symbolically, to a bearing block 35 of the crankcase 20, which is screwed or cast onto the area 18 of the crankcase 20.
  • the other ends of the force receiving elements 32 are connected to the directly adjacent to the oil pan 12 region 30 of the transmission housing 24 via bearings 36.
  • the bearings 34 and 36 are designed so that essentially only compressive and tensile forces are introduced into the force receiving elements 32a to 32d.
  • a plug connection is provided in the region of the bearings 34, and a screw connection is provided in the region of the bearings 36.
  • the force receiving elements 32a to 32d are supported by the collecting portion 14 of the oil pan 12. These are in the side walls 38 of the collecting section 14 regions 40a to 40d with a greater wall thickness available. In these elongated recesses 42a to 42d are present in which the force receiving elements 32a to 32d are partially received.
  • the outside of the force receiving elements 32a to 32d coated with a decoupling layer 44 of a rubber material the decoupling layer may also comprise a plastic or Teflon material. It is essential that the coating reduces or even completely prevents transmission of forces from the force receiving elements 32a to 32d into the side wall 38 of the collecting section 14 of the oil sump 12.
  • ribs 50 are additionally formed on its bottom 46 and on a rear end wall 48.
  • these ribs 50 may be similar to the areas 40a to 40d of the side wall 38 used for holding or receiving force receiving elements, so that the bottom 46 even more dynamic loads that are introduced from the transmission housing 24 is released ,
  • the ribs 50 shown also serve to guide the flow of oil within the collecting section 14.
  • FIGS. 5 to 7 A second embodiment of an oil pan arrangement is shown in FIGS. 5 to 7.
  • the two force receiving elements 32a and 32b Due to the design as flat bars, the two force receiving elements 32a and 32b have an extremely high flexural rigidity about an axis 60 extending transversely to the longitudinal extent of the two force receiving elements 32a and 32b and in the normal operating position approximately horizontally (see FIG nevertheless extremely light.
  • the collecting section 14 of the oil pan arrangement 10 has a region 62 with a larger height and an area 64 with a lesser height.
  • the two force receiving elements 32a and 32b each have a region 66 of lesser height and a region 68 of greater height.
  • the region 66 in turn tapers towards the free end and toward the transmission housing (arrow 24).
  • a step-shaped contour can also be selected, as is indicated by a dashed line 69 in the element 32b in FIG.
  • the region 66 of a force-receiving element 32a or 32b, which has a greater height, is, as can be seen in FIGS. 6 and 8, accommodated in a pocket-shaped recess 42a or 42b in the collecting section 14 of the oil sump 12.
  • the lower height portion 68 is substantially exposed outside the side wall 38 of the collection portion 14. In this way, sealing problems due to the presence of the force receiving members 32a and 32b are avoided.
  • a total of six passage openings 70a to 70f are present in the force receiving elements 32a and 32b, whose position is matched to corresponding fastening bores 72a to 72f in the fastening flange 16 of the collecting section 14.
  • corresponding bolts 73 in Figure 8 is for illustrative purposes only one provided with a reference numeral
  • FIG. 8 is for illustrative purposes only one provided with a reference numeral
  • connection of the force receiving elements 32a and 32b to the adjacent region 30 of the gear housing 24 takes place, as can be seen particularly well in FIG. 8, via the axial end face 74 of a force-receiving element 32a or 32b facing the gearbox housing 24.
  • a screw bolt 75 is screwed from the gear housing 24, which is received in a tube sleeve 76a and 76b, which is clamped between the axial end surface 74a and 74b of a force receiving member 32a and 32b and the gear housing 24.
  • a force-and torque-locking connection between the adjacent to the oil pan 12 region 18 of the crankcase 20 and the oil pan 12 adjacent portion 30 of the gear housing 24 is provided, which reduces the introduced into the oil pan 12 loads.
  • FIG. 5 shows that the oil pan 12 as a one-piece injection molded part including bottom 46, side walls 38, ribs 50, etc., can be produced.
  • An oil suction tube 78 and a perforated plate 80 (FIG. 5), which likewise serves to reinforce, may be formed integrally with the side walls 38 or the bottom 46 at least in regions.
  • a lid which may be secured to a flange 82 of the collection section 14 which fluid-tightly seals the collection section and which optionally includes an oil cooler is not shown.
  • the force receiving elements 32a and 32b can in the installed position down over the bottom 46 of the collecting portion 14 partially (reference numeral 78) survive. This can be seen from FIG. 8, which shows an oil pan arrangement 10 modified in this point compared to FIGS. 5 to 7. Due to the projections 78 of the force receiving elements 32a and 32b is a direct contact of the collecting portion 14 with a below the collecting portion 14 existing Subsurface (not shown) prevented.
