Definitions

  • the invention relates to an internal combustion engine with a cylinder crankcase and a connection housing.
  • crankcase for an internal combustion engine, in which the crankcase is cuboid with a rectangular cross-section, the base of the cuboid approximately corresponding to the lateral projection in the area of the cylinder heads, the crankcase has a chamber which extends from the longitudinal side of the crankcase into the interior of the Crankcase has and the chamber is formed from the two end walls, part of the base and a wall delimiting the crankshaft space.
  • the DE 102 20 838 C1 discloses an internal combustion engine with 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, with an oil pressure control valve downstream of the oil pump to limit the oil pressure, the valve body of which is held in place by a spring element in Closing direction can be acted upon, the valve body releasing an opening depending on the oil flow rate and / or the oil temperature, which can be connected to the suction side of the oil pump, wherein the crankcase is provided with an inclined parting plane.
  • the DE 10 2013 020 944 A1 discloses a crankcase according to the preamble of claim 1.
  • the object of the invention is to develop it further.
  • crankcase for an internal combustion engine is created, with at least one oil pan flange and a one-piece crankshaft, with at least one end face of the crankcase, on which the wheel drive is arranged, for example, having a machining of the sealing surface towards the timing case cover, which in a Angle of about 4 ° to the vertical with respect to the oil pan flange surface is arranged.
  • the advantage here is that the overall length of the crankcase is reduced, which also has an impact on costs.
  • crankcase has a cover or a gear case that is releasably attached to the processing of the sealing surface for the gear case cover, which is arranged at an angle of about 4° to the vertical with respect to the oil pan flange surface.
  • the length of the motor is crucial in order to keep the devices in which this motor is to be installed compact.
  • a criterion for the engine length is the cylinder crankcase and the attachment of the oil pan or its sealing to the cylinder crankcase.
  • the gear drive is a co-determinant for the oil sump sealing surface and thus for the engine length.
  • the cylinder crankcase (1) has a sealed passage (2) for the gear wheel to the camshaft mounted in the cylinder head.
  • the other gears on the crankcase side are covered by a cover/gear case (3).
  • the oil pan seal is then made via the crankcase and the cover.
  • the seal-converted balcony to the cylinder head can be dispensed with by forming a cover/wheel case that seals both the cylinder head and the oil pan.
  • the tolerance problem that arises from this, namely the height of the cylinder crankcase must correspond to the height of this gear case, since on the other hand a sealing crack occurs on one of the two surfaces to be sealed, has not yet been solved.
  • crankshaft due to the surrounding edge of the cylinder block, is so short that it has to be equipped with extension components that bridge the passage through the cylinder block wall, in order to establish the connection with e.g. B. gears, flywheel and other attachments.
  • the present solution makes it possible to reduce the overall length of the engine without having to accept the disadvantages of the multi-part crankshaft.
  • This is achieved by machining the sealing surface for the timing case cover on the side of the cylinder crankcase on which the gear train is arranged, which is at an angle, e.g. B. 4 °, based on the perpendicular to the oil pan sealing surface, takes place that is chosen is that the passage 2 of the gear wheel required to the cylinder head remains sealed and the cylinder crankcase becomes steadily shorter towards the oil pan/oil pan sealing surface 4.
  • the sealing counter-contour 5 that is now locally missing on the oil pan is then formed by the gear case cover, which has the complementary angle to the surface of the cylinder crankcase .
  • the timing case cover is designed here in one piece 6 or in two pieces 7 with the connection housing.
  • the fastening screws and the centering of the connection housing/wheel housing are designed in such a way, advantageously parallel to the longitudinal axis of the crankshaft, that the housing is aligned with the center of the crankshaft.
  • a gradation of the screw-on slugs, which results from the machining bevel, is possible 8.
  • An alternative for the fastening screws is to design the centering hole parallel to the longitudinal axis of the crankshaft and the fastening screws perpendicular to the sealing surface.
  • a cylinder crankcase 1 with a passage for the gear wheel to the camshaft 2 is shown.
  • a in 1 The cover/gear case 3 (not shown) would rest against the machining of the sealing surface for the gear case cover 4 , with the gear case cover 3 (not shown) having a sealing counter-contour on the gear case cover 5 .
  • the timing case covers can be in one piece (6) or in two pieces (7).
  • the gradation of the screw-on slugs 8, resulting from the processing slope according to 1 results is in 2 shown.
  • the oil pan 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 area of the crankcase 1 .
  • EGR exhaust gas recirculation
  • EGR cooler mount 11 At the same level, to the left of EGR duct 10, is the EGR cooler mount 11. Below the EGR duct 10 and the EGR cooler mount 11 is the starter mount 12. According to the invention, it is located diagonally above the EGR duct on one end face of the Crankcase 1 a nose-like Accumulation of material in the area where the gear wheel passes through to the camshaft 13, which is adjacent to the cylinder head gasket surface 14.
  • the cover or gear box 3 shows a cylinder crankcase 1 with a passage for the gear wheel to the camshaft 2.
  • the cover or gear box 3 is located on the in 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, which is in the Figures 6a and 6b to be shown.
  • the gear case cover can be in one piece 6 or in two pieces 7, which is also in the Figures 6a and 6b you can see.
  • the gradation of the screw-on slugs 8, resulting from the processing slope according to 1 results is in 2 shown and is used to connect the cylinder crankcase 1 and gear case cover 3.
  • the oil pan 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 area of the crankcase 1 below the cylinder head gasket surface 14 .
  • EGR exhaust gas recirculation
  • the EGR cooler mount 11 At the same height, to the left of EGR channel 10 and below the cylinder head gasket surface 14, is the EGR cooler mount 11.
  • the starter mount 12 Below the EGR channel 10 and the EGR cooler mount 11 is the starter mount 12. Diagonally above the EGR channel on one On the front side of the crankcase 1 there is a nose-like accumulation of material in the area where the gear wheel passes through to the camshaft 13 , which adjoins the cylinder head gasket surface 14 .
