Definitions

  • the invention relates to an internal combustion engine according to the preamble of claim 1.
  • the object of the invention is to provide an internal combustion engine whose crankcase and crankshaft are designed on one end face in such a way that auxiliary units and / or endless links of the internal combustion engine are covered in a cost-effective and weight-saving manner with functional drive in a noise-free manner.
  • the main advantages achieved with the invention can be seen in the fact that the cladding, the auxiliary units and endless links on the end face of the crankcase cover with little noise.
  • the cladding formed by two relatively thin-walled sheet metal layers is easy to manufacture and lightweight. In addition, it easily absorbs thermal expansion of the light metal crankcase, for example.
  • extension connected to the crankshaft, not only a short construction is possible with the said crankshaft, but the drive of the auxiliary units and the endless links can be carried out effectively realize.
  • the extension also helps to simplify the assembly of the auxiliary units and / or endless links.
  • An internal combustion engine 1 comprises a crankcase 2, which has two integrally formed cylinder rows 3, 4 - V-type - and is designed to receive a crankshaft 5.
  • the crankshaft 5 is configured adjacent to an end face 6 of the crankcase for driving auxiliary units, such as oil pump 7 and alternator, as well as endless members 8, 9.
  • a drive wheel 10 connected to the crankshaft 5 interacts with the alternator, not shown; the endless links 8, 9 with camshafts, also not shown, arranged above the cylinders.
  • the oil pump 7 projects with a housing 11 beyond the end face 6 of the crankcase 2 and is attached to the crankcase 2 at 12 by means of screws 13.
  • crankcase 2 To assemble the endless members 8, 9 and their tensioning and / or sliding devices, the crankcase 2 has an opening 14 on the end face 6, which is delimited by a wall 14 '.
  • the endless links 8, 9 and the oil pump 7 are covered by a cladding 15, which consists of sheet metal and in fact consists of two thin-walled, contacting layers 16, 17 (FIG. 3).
  • the thickness of the layers 16, 17 is approximately 0.5 mm.
  • the lining 15 is cup-shaped (FIG. 2), whereby it is formed by means of an edge flange 18 runs along the wall 14 'of the crankcase 2 and a plurality of screws 19 is attached to the end face.
  • the cladding 15 is supported on the outside of the housing 11 by a section 20 of a base wall 21 and by means of a sealing body 22.
  • the section 20 has an expression 23 which is guided away from the base wall 21 and the housing 11 has a recess 24.
  • the base wall 21 is also provided with an opening 25 within the expression 23.
  • the covering 15 has between the edge flange 18 and the base wall 21 a frame-like wall 26 which extends perpendicular to the edge flange 18.
  • the base wall 21 is convexly curved at least locally (see at 27). The bend 28 on the free side of the edge flange 18 serves the same purpose.
  • the base wall 21 is also fastened by means of a screw 29 to a fixed part 30 of the crankcase 2.
  • the base wall 21 has an indentation 31 there.
  • the fixed part 30 is a fastening pin 32 for a tensioning and / or sliding rail 33 of the endless member 9.
  • crankshaft 5 ends in the area of a bearing block 35 of the crankcase 2, the bearing block 35 running at a parallel distance from the end face 6.
  • a sleeve-like axial extension 36 of the crankshaft 5 is used to drive the oil pump 7, including the endless links 8, 9.
  • the extension 36 which is a separate component, cooperates with the oil pump 7 at 37 and is provided with a drive wheel 38 for the endless link 9 provided.
  • Another drive wheel 39 for the endless member 8 is shown in the exemplary embodiment as a separate component which is connected to the crankshaft 5 in a rotationally fixed manner. But this can also be made in one piece with the extension 36.
  • the extension 36 and the crankshaft 5 are connected by means of a screw 40, which is effective in the axial direction of the crankshaft 5, that is, it is screwed into an axial threaded bore 41 of this shaft.
  • the screw 40 clamps by means of a washer 42 and the drive wheel 10 (for the alternator), the extension 36 against the crankshaft 5.
