Definitions

  • the invention relates to an internal combustion engine with a cylinder crankcase and a connection housing.
  • crankcase for an internal combustion engine discloses, in which the crankcase is cuboidal with a rectangular cross section, in this case the base side of the cuboid corresponds approximately to the lateral projection in the region of the cylinder heads, the crankcase has a chamber, this from the longitudinal side of the crankcase in the interior of the Crankcase has and the chamber from the two end walls, a part of the base and a crankshaft space defining wall is formed.
  • the DE 102 20 838 C1 discloses an internal combustion engine having a crankcase, a crankshaft and a camshaft for controlling at least one inlet and outlet valve and an oil pump for delivering lubricating oil to the consumers, the output side of the oil pump for limiting the oil pressure an oil pressure control valve is connected downstream of the valve body by a spring element in Closing direction can be acted upon, wherein the valve body in response to the oil flow rate and / or the oil temperature releases an opening which is connectable to the suction side of the oil pump, wherein the crankcase is provided with an inclined dividing plane.
  • the invention has the object to further develop this.
  • crankcase for an internal combustion engine, with at least one ⁇ lwannenflansch and one-piece crankshaft, wherein at least one end face of the crankcase, on which, for example, the gear drive is arranged, a processing of the sealing surface to the timing case cover out in an angle of about 94 ° to the vertical with respect to the ⁇ lwannenflansch requirements is arranged.
  • the advantage here is that the overall length of the crankcase is reduced, which also has an effect on the costs.
  • crankcase has a cover or a gear box, which is arranged releasably secured to the processing of the sealing surface to the timing case cover, which is arranged at an angle of about 94 ° to the vertical with respect to the ⁇ lwannenflansch phenomenon.
  • the cylinder crankcase (1) has a sealed passage (2) for the gear for the camshaft mounted in the cylinder head.
  • the other crankcase side gears are covered by a cover / wheel box (3).
  • the oil pan gasket is then carried over the crankcase and the lid.
  • crankshaft due to the peripheral edge of the cylinder crankcase, builds so short that it must be equipped with extension components that bridge the passage through the cylinder crankcase wall to connect to z. As gears, flywheel and other attachments to allow.
  • the present solution makes it possible to reduce the length of the engine without having to accept the disadvantages of the multi-part crankshaft. This is achieved by on the side of the cylinder crankcase, on which the gear drive is arranged, a processing of the sealing surface is performed to the timing case cover, which at an angle, for. B. 94 °, based on the perpendicular to the oil pan sealing surface, takes place, so chosen is that the required passage to the cylinder head 2 of the gear remains sealed and the cylinder crankcase to the oil pan / oil pan sealing surface is steadily shorter 4.
  • the timing case cover having the complementary angle to the surface of the cylinder crankcase ,
  • the timing case cover is here in one piece 6 or two parts 7 formed with the connection housing.
  • the fastening screws and the centering of the connection housing / gear box are formed, advantageously parallel to the crankshaft longitudinal axis, that the alignment of the housing is given to the center crankshaft.
  • a grading of the Anschraubbutzen, resulting from the working slope, is possible 8.
  • An alternative of the fastening screws is to form the center hole parallel to the crankshaft longitudinal axis and the mounting screws perpendicular to the sealing surface. As a result, a precise centering is possible and the Anschraubvorgang caused by angle no transverse force that can cause a shift of the components with each other and thus could affect the accuracy of connection housing to the middle crankshaft negative.
  • a cylinder crankcase 1 is shown with a passage for the gear to the camshaft 2.
  • An in Fig. 1 not shown cover / gear box 3 would abut the machining of the sealing surface to the timing case cover 4, wherein the timing case cover 3, not shown, a sealing counter contour on the timing case cover 5 has.
  • the timing case covers may be one-piece (6) or two-piece (7).
  • the grading of Anschraubbutzen 8, resulting from the processing slope in accordance with Fig. 1 results in is Fig. 2 shown.
  • the oil sump sealing surface 9 is arranged at the lower end of the crankcase 1.
  • an exhaust gas recirculation (EGR) channel 10 is arranged in the upper region of the crankcase 1.
  • the EGR cooler receptacle 11 At the same level, to the left of EGR channel 10, there is the EGR cooler receptacle 11. Under the EGR channel 10 and the EGR cooler receptacle 11, the starter receptacle 12 is located obliquely above the EGR channel on one end side of the crankcase 1 itself a nose-like Material accumulation in the region of the passage of the gear to the camshaft 13, which is adjacent to the cylinder head gasket surface 14.
  • Fig. 3 shows a cylinder crankcase 1 with a passage for the gear to the camshaft 2.
  • the lid or gear box 3 is located on the in Fig. 1 illustrated processing of the sealing surface to the timing case cover 4, wherein the timing case cover 3 has a sealing counter contour on the timing case cover 5, in the Fig. 6a and 6b to be shown.
  • the timing case cover can be one piece 6 or two parts 7, which also in the Fig. 6a and 6b you can see.
  • the grading of Anschraubbutzen 8, resulting from the processing slope in accordance with Fig. 1 results in is Fig. 2 and serves to connect the cylinder crankcase 1 and the timing case cover 3.
  • the oil pan sealing surface 9 is arranged at the lower end of the crankcase 1.
  • an exhaust gas recirculation (EGR) passage 10 is disposed below the cylinder head sealing surface 14.
  • EGR exhaust gas recirculation
  • the starter receptacle 12 is located obliquely above the EGR channel on one side
  • Front side of the crankcase 1 is a nose-like accumulation of material in the region of the passage of the gear to the camshaft 13, which is adjacent to the cylinder head sealing surface 14.
  • Fig. 4a is a plan view of the crankcase 1 according to Fig. 1 from below on the split sump gasket surface 9 with mounted (shrunk) crankshaft 19 disclosed.
  • Fig. 4b shows a plan view of the crankcase 1 according to Fig. 1 from below on the closed sump gasket surface 9 with built (screwed) crankshaft 18 disclosed.
  • Fig. 5 a is a plan view of the crankcase according to Fig. 4a, b from below on the oil sump sealing surface 9 with mounted timing case cover 3, which is in two parts 7, as well as with divided ⁇ lwannenflansch.
  • Fig. 5 b represents a plan view of the crankcase according to Fig. 4a, b from below on the oil pan sealing surface 9 without mounted timing case cover 3 with closed ⁇ lwannenflansch 9 is.
  • Fig. 6a and 6b has the timing case cover 3 a sealing counter contour on the timing case cover 5, which in the Fig. 6a and 6b to be shown.
  • the timing case covers can be one piece 6 or two pieces 7.
