Definitions

  • the invention relates to a cover plate for a crankcase according to the preamble of the first claim and a method for mounting the cover plate.
  • a crankcase is known from the applicant's DE 198 55 562 C1.
  • this has further chambers which extend from the long side of the crankcase into the interior. These chambers are formed from the two end walls, part of the base area and a wall delimiting the crankshaft space.
  • the auxiliary units in particular pumps and heat exchangers, filter and oil storage rooms, are arranged in the chambers. When completed, the auxiliary units are assembled from the long side. The chambers are then sealed using a side cover. In the area of the crankshaft space, the base area of the crankcase is closed by a cover plate.
  • the object of the invention is to develop it further with a view to a more assembly-friendly solution.
  • a cover plate for a crankcase which extends over the entire base area of the crankcase.
  • the auxiliary units are mounted on this cover plate, so that they form a structural unit.
  • the cover plate have channels for media guidance and recesses.
  • the solution according to the invention and its embodiments offer the advantage that the cover plate with the auxiliary units can be used in one operation from the underside of the crankcase. Compared to the prior art, this results in less installation effort or improved serviceability.
  • the number of sealing points on the crankcase is reduced by integrating the channels for media guidance in the cover plate.
  • the connecting line between a pump and a heat exchanger is passed through the crankshaft chamber.
  • the corresponding bushings for the lines can now be omitted in the manufacture of the crankcase. This results in a cost reduction in the manufacture of the crankcase.
  • the cover plate have a first and second suction point for the pumps.
  • the cover plate have a fluid guide device, by means of which the lubricant is guided from the crankshaft chamber to these first and second suction points. Dry sump lubrication can be achieved via this fluid guide device and the two suction points.
  • Figure 1 is a partial view of the crankcase
  • FIG. 2 shows the cover plate
  • Figure 4 is a first sectional view
  • Figure 5 shows a second sectional view
  • Figure 6 shows a third sectional view
  • crankcase 1 a partial view of the crankcase 1 is shown.
  • the crankcase 1 is formed from a cover plate 2, end walls 3 and side walls 4. At least one chamber 5 and a crankshaft space 9 are located within the crankcase 1.
  • a crankshaft is shown in the crankshaft space 9 without reference numerals.
  • a gear train 8 is shown on the opposite side of the force.
  • the crankcase according to FIG. 1 has three chambers 5 on each side. They are in these chambers Auxiliary units, here heat exchangers 6 and pumps 7 and filters, are arranged. These chambers 5 also serve as oil storage rooms.
  • the side walls 4 are made in one piece with the crankcase 1. This increases the overall rigidity of the crankcase 1.
  • the end walls 3 stand on the cover plate 2.
  • the end walls 3 it is also possible for the end walls 3 to cover the end faces A, B of the cover plate 2 without changing the essence of the invention.
  • the end faces A, B are shown in Figure 1 and Figure 2.
  • FIG. 2 shows the cover plate 2 in a perspective view.
  • the heat exchangers 6 and the pumps 7 are already mounted on the cover plate 2.
  • the pumps 7 are suction and pressure pumps.
  • Reference numerals 10 and 11 denote first and second suction points for the pumps 7.
  • Reference number 12 shows a fluid guide device, by means of which the lubricant is fed from the crankshaft chamber 9 to the first and second suction points 10 and 11, respectively.
  • Channels for media guidance are integrated in the cover plate 2. These can be seen in FIG. 3.
  • Recesses 20 are shown as an example in FIG. These are located around the channels for media guidance. Exceptions to this are the areas for sealing, for example cover plate 2 for crankcase 1 from the environment, area C in FIG. 5, and areas for screwing. Via these recesses 20, the lubricant degassed and calmed down in the chambers 5 can reach a suction channel 15, see FIG. 3.
  • the cover plate 2 is shown with the channels for media management in a view.
  • the recesses 20 are omitted from this figure for reasons of clarity.
  • the lubricant dripping from the crankshaft chamber 9 is fed by the fluid guide device 12 to the first suction point 10 or second suction point 11.
  • the lubricant is drawn in from the first suction point 10 via channel 18 by a first suction pump SP1.
  • the suction direction is shown by a corresponding arrow.
  • the lubricant of the second suction point 1 1 is drawn in via a channel 19 by a second suction pump SP2.
  • the lubricant volume delivered by the two suction pumps SP1 and SP2 is then fed to a channel 13. This is shown in FIG the reference symbol V1 and a corresponding arrow.
  • the lubricant is supplied to the chambers 5 via the channel 13.
  • the lubricant is degassed and calmed in the chambers 5.
  • the first or second suction pump SP1 or SP2 can be conveyed in air.
  • the degassed and calmed lubricant can then via
  • Recess 20 reach under the fluid guide device 12 to a suction channel 15.
  • the lubricant is conveyed by a pressure pump DP via this suction channel 15.
  • the delivered volume V2 is supplied to the heat exchangers 6 via a channel 17.
  • the cooler water KW is supplied or discharged to the heat exchangers 6 via channels 14.
  • a channel 16 serves to discharge the lubricant from the heat exchangers 6 to a filter, not shown.
  • FIG. 3 three cutting lines are drawn.
  • a section along the line IV through the left side of the crankcase 1 with cover plate 2 is shown in Figure 4.
  • a section along the line V through the left side of the crankcase 1 with cover plate 2 is shown in Figure 5.
  • a sectional view along line VI through the right side of crankcase 1 with cover plate 2 is shown in FIG.
  • FIG. 4 shows a first sectional view through the left side of the crankcase 1 with the cover plate 2, along the line IV.
  • the pressure pump DP can be seen in FIG.
  • the suction pumps Sp1 / Sp2 are behind.
  • the two suction pumps convey the lubricant located in the two suction points 10 and 11 into the channel 13 via channels 18 and 19.
  • the degassed and calmed lubricant is then sucked in by the pressure pump DP via the suction channel 15.
  • the pressure pump DP conveys the lubricant via channel 17, volume V2, to the heat exchangers 6.
  • the fluid guide device 12 is embodied in one piece with the cover plate 2.
  • FIG. 4 shows a second sectional view through the left side of the crankcase 1 with cover plate 2 along the line V.
  • recesses 20 can be seen. These are located around the channels for media guidance. Exceptions to this are the areas for sealing, for example cover plate 2 for crankcase 1 with respect to the environment, area C, and areas for screwing.
  • the degassed and calmed lubricant of the chambers 5 can reach the suction channel 15 via these recesses 20. Via the suction channel 15, the lubricant is conveyed from the pressure pump DP via channel 17 to the heat exchangers 6.
  • FIG. 4 apply to the function of the fluid guide device 12.
  • FIG. 6 shows a third sectional view through the right half of the crankcase 1 with the cover plate 2.
  • the connections of a heat exchanger 6 can be seen in this section.
  • the lubricant delivered by the pressure pump DP is supplied via the channel 17. Via the channel 16, the lubricant is fed to an oil filter after the heat exchanger 6.
