Definitions

  • the invention relates to an oil pan for an internal combustion engine according to the preamble of claim 1.
  • an oil pan which has a arranged in the region of a gear flat and arranged in the region of a crankcase of an internal combustion engine deep bottom portion.
  • the oil pan is open to the crankcase and gearbox.
  • the edge of this oil pan has a sealing area, through which the oil pan is sealed against the crankcase and the transmission.
  • Object of the present invention is to provide an oil pan with a particularly reliable and good seal against that housing part or those housing parts on which or to which the oil pan is attached.
  • the rigidity of the oil pan is significantly increased.
  • the oil pan without loss of rigidity at least partially flatter than previously executed, which allows an increase in space and, for example. In the case of a motor vehicle, ground clearance.
  • the production is simplified if the sealing region has a shoulder to which the stabilizing part is attached.
  • a particularly favorable frictional connection between the stabilizing part and the bottom section is created when the sealing region has a groove into which the stabilizing part engages.
  • the stabilization part can also be attached to the sealing area in a blunt manner. In this case At the sealing area itself, no changes are required.
  • the sealing region can also be arranged on the stabilizing part, wherein, however, attention must then be paid to a good sealing by a corresponding connection of the stabilizing part to the bottom section.
  • the rigidity is again significantly increased when the oil pan comprises at least one arranged between opposite sealing areas web or pin, which additionally connects the stabilizing part with the bottom portion. This counteracts a strength-reducing bulging of the stabilization part and also of the bottom section, and also noise-causing vibrations of the stabilization part and of the bottom section are reduced.
  • the web and / or pin may be integrally formed on the stabilizing part or on the bottom portion.
  • the production of the stabilizing part or the bottom portion of the oil pan is simplified.
  • the stabilizing part there may be oil calming passages extending from an upper side of the stabilizing part into a space between Stabilization and ground section lead. This gives the stabilizing part an additional oil calming function. Their effect is further improved if at least one oil calming channel runs in sections in a web, because this extends the oil calming channel.
  • a development of the oil sump according to the invention is that at least part of an oil suction pipe is integral with the stabilizing part.
  • the stabilizing part receives another function, namely the holder or receiving a ⁇ lsaugrohrs. This also has advantages in the manufacture of the oil pan, since the separate handling of at least this part of the ⁇ lsaugrohrs deleted.
  • At least a part of an oil suction pipe can also run in a web. This also reduces the number of parts to be handled during assembly of the oil pan according to the invention.
  • connection of the stabilizing part with the bottom portion comprises a tongue and groove connection.
  • the rigidity of the stabilization part is increased if it has a zig-zag folding and / or waveform at least in sections. Also, the flow of oil can be influenced in a desired manner.
  • a filling part which has a zig-zag fold and / or wave shape or is made of a porous material.
  • Such a filling part likewise prevents or at least impedes buckling of the bottom section and / or the stabilizing part and thus increases the strength of the oil sump.
  • the area of the stabilizing part projecting beyond or into the deep section serves for holding at least one functional element, for example an oil suction pipe and / or an oil filter.
  • the stabilizing part has an additional function, and it can be dispensed with a separate support of the ⁇ lsaugrohrs and / or the oil filter. This facilitates handling during assembly in the oil pan and thus reduces the manufacturing costs.
  • the oil sump comprises an oil planer, which is formed at least in part by the stabilizing part.
  • the stabilizing part fulfills a further additional function, so that it is possible to dispense with a corresponding separate part, which simplifies handling during assembly of the oil sump.
  • the oil pan comprises an oil planer, which is at least partially formed by a arranged in the installed position in the region of the deep portion of the oil pan part, which is mounted in the installed position on the crankcase or a corresponding housing. This also serves to simplify the assembly of the oil pan according to the invention.
  • a portion of an oil suction pipe and / or an oil filter is attached to or integrally formed on the part of the oil planer arranged in the region of the deep portion of the oil pan.
  • the oil planer thus receives an additional function, namely the mounting of a ⁇ lsaugrohrs or an oil filter. This eliminates parts to be handled separately, which makes the manufacture of the oil pan easier and cheaper.
  • FIG 1 An oil sump bears in Figure 1 overall the reference numeral 10. It is screwed to a crankcase 12 of an internal combustion engine from below. For this purpose, it has at its upper end in Figure 1 via a sealing region 14, with which it is sealed relative to the crankcase 12. The exact configuration of this sealing region 14 will be described below.
  • the oil pan 10 In its left in Figure 1 area, the oil pan 10 has a much greater depth than its right in Figure 1 area.
  • the left in Figure 1 region of the oil pan 10 is therefore referred to as a lower bottom portion 16, the right area as a flat bottom portion 18.
  • the oil pan 10 is shown in perspective in FIG. It can be seen on the sealing region 14, a plurality of eyelets 20; of which only one bears a reference numeral and over which the oil pan 10 is bolted to the crankcase 12.
  • the lateral sealing areas are denoted by the indices a and b, an end sealing area by the index c.
  • a stabilizing part 22 is welded on the oil pan 10. This comprises a plurality of oblong openings 23, only one of which bears a reference numeral and can pass through the oil dripping down from the crankcase 12 into a space 24 (see FIG. 1) located between the stabilizing part 22 and the fastening eyes 20.
  • the stabilizing part 22 forms an oil planer.
  • an oil suction pipe 26 is arranged in the area of the deep bottom portion 16 of the oil pan 10.
  • the stabilizing part 22 is welded to an edge 28 on a shoulder 30 on the sealing region 14a (reference numeral 32).
  • the opposite sealing region 14b is mirror-symmetrical, the end-side sealing region 14c is formed accordingly.
  • a plurality of extending in the longitudinal direction of the oil pan 10 webs 34 are integrally formed on the flat bottom portion 18, the protruding edge is also welded to the stabilizing member 22.
  • the corresponding welding area is also designated 32.
  • the stabilizing part 22 together with the flat bottom portion 18 forms a double shell 36 stiffening the sealing region 14a.
  • This has a high flexural rigidity, for example, about the dot-dash line in FIG drawn section line III-III.
  • the sealing area 14 is stiffened and created a better seal between the oil pan 10 and the crankcase 12.
  • the sealing region 14a like the sealing regions 14b and 14c, consists of a peripheral groove 38 for a seal 40.
  • the groove 38 is bounded by two groove walls 42 and 44 which are substantially perpendicular to the plane of the flat bottom portion 18.
  • the stabilizing part 22 projects beyond the flat bottom section 18 beyond the deep bottom section 16. In this area, the stabilizing section 22 is supported by additional webs 46 at the deep bottom section 16.
  • FIG. 10 An alternative embodiment of the oil pan 10 is shown in FIG.
  • elements and regions which have equivalent functions to previously described elements and regions bear the same reference numerals and are not explained again in detail.
  • the sealing region 14 a is not arranged on the flat bottom portion 18 but on the stabilizing part 22. This is welded to the flat bottom portion 18 immediately below the sealing area 14a in FIG. Moreover, in the embodiment shown in Figure 4, the webs 34 are not formed on the flat bottom portion 18, but on the stabilizing part 22 and welded in Figure 32 with the flat bottom portion 18.
  • FIG. 5 A further alternative embodiment is shown in FIG. 5: This is similar to that of FIG. 3, wherein a tongue-and-groove connection 48 is present in the region of the weld 32 between the stabilizing part 22 and the flat bottom portion 18.
  • a hook connection 50 is present instead of a welding between stabilizing part 22 and flat bottom section 18 or webs 34.
  • the stabilizing part 22 has a waveform 52, in the embodiment according to FIG. 13 a zigzag fold 54.
  • an embodiment of an oil sump 10 is conceivable in which a filling part 56 is arranged between the stabilizing part 22 and the flat bottom section 18 and has a zig-zag fold. Also possible is a wave form of the filling part 56 and / or the production of the filling part 56 made of a porous material.
  • FIG. 10 Another variant of an oil pan 10 can be seen in FIG. This has similarities with the oil pan 10 of Figure 4.
  • two webs 58a and 58b facing the sealing area 14a on the stabilizing part 22 are integrally formed on the flat bottom portion 18, and the corresponding area on the sealing area 14a is designed to be complementary thereto. In this way, a kind of "labyrinth" created with different welding points 32a to d.
  • the oil sump 10 shown in FIG. 10 is characterized in that the edge 28 of the stabilizing part 22 is butt-welded to the sealing area 14 a of the flat bottom portion 18.
  • the variant of an oil sump 10 shown in FIG. 11 has two special features: On the one hand, on the side of the groove wall 42 facing the stabilizing part 22 there is a groove 58 in which the edge 28 of the stabilizing part 22 engages. On the other hand, in the stabilizing part 22 oil calming channels 60 are present, which lead from an upper side of the stabilizing part 22 into the space 24 between the stabilizing part 22 and the flat bottom portion 18.
  • the oil calming channels 60 extend in sections with a corresponding branching 60a and 60b in the webs 34, which connect the stabilizing part 22 with the flat bottom portion 18.
  • FIG 12 A similar variant is shown in FIG 12: In this, however, the webs 34 are obliquely executed, and the ⁇ lberuh Trentskanäle 60 open into the space 24 directly at the base of a respective web 34 on the stabilizing part 22. Oil passing through an oil calming channel 60 therefore initially flows on the inclined web 34 to the flat bottom portion 18. In a similar direction aims the development according to Figure 13, to which reference has already been made above in connection with the zigzag folding 54 of the stabilizing member 22. Also in this stabilizing part 22 ⁇ lruh Trentskanäle 60 are present.
  • FIG. 14 shows a further modified embodiment of an oil pan 10 in Figure 14:
  • the webs 34 are drawn only by dashed lines. It can be seen that a portion 34a of the webs 34 with respect to a longitudinal axis 62 of the oil pan 10 extends at an angle 64 which is greater than 0 and less than 90 ° at approximately 45 °.
  • the sections 34a are adjoined by sections 34b, which run parallel to the longitudinal axis 62.
  • the slit-shaped openings 23 are arranged in the stabilizing part 22 parallel to the sections 34a "upstream” thereof. "Upstream” means that the flat bottom portion 18 has a slope that allows the oil to flow toward the deep bottom portion 16.
  • FIG. 15 shows a variant in which the webs 34 are aligned overall at an angle 64 of approximately 45 ° to the longitudinal axis 62.
  • the webs 34 can also be arranged in a nested manner with circular openings 23 (provided only once with reference symbols) upstream of a web 34.
  • the oil suction pipe 26 is arranged as a separate part in the deep bottom portion 16 of the oil pan 10.
  • a variant not shown in the drawing for this purpose may consist in that the region of the stabilizing part 22 projecting beyond the deep bottom section 16 serves to hold the oil suction pipe 26.
  • Another, also not shown variant could include a separate oil planer, which is attached directly to the crankcase 12 in the region of the deep bottom portion 16 and which serves to hold the ⁇ lsaugrohrs 26.
  • the oil suction pipe 26 may be formed integrally with such an oil planer.
  • At least a part of the oil suction tube 26 can also be integral with the stabilizing part 22 in the region of the flat bottom section 18 in that a part of the oil suction tube 26 extends in a web 34.
