Definitions

  • the invention relates to a cylinder crankcase of an internal combustion engine with water cooling, with cylinders arranged in series, an oil pump, a water transfer from the cooling water pump to the oil cooler, the oil cooler and oil filter being flanged to the crankcase, and the oil suction channel to the oil pump and the oil suction chamber of the oil pump, the oil pressure chamber of the oil pump and the transfer from the oil pressure chamber into the oil cooler chamber and into the oil filter, the mounting of the internal toothing of the oil gear pump and the mounting of the oil pump bearings with the cylinder crankcase are cast.
  • DE-OS 38 03 546 describes a cooling system for water cooling engine oil of a motor vehicle, in which the oil pump housing, including the oil suction channel, oil pressure channel, and the inclusion of the internal toothing of the oil gear pump are made in one part with the cylinder crankcase. However, the water pump housing and thermostat housing are not integrated in the cylinder crankcase. The type and design of the oil return from the cylinder head is not apparent from DE-A.
  • GB-A 2 168 750 describes a special oil flow option for cooling the oil, flow channels for lubricating oil and cooling water being made in one piece with the cylinder crankcase. All other essential parts, e.g. However, the oil pump, water pump, thermostat housing and mass balance housing are not made in one piece with the cylinder crankcase.
  • Cylinder crankcases of this known type are usually cast and at least some of the auxiliary oil-water-carrying devices are mostly attached to the crankcase and connected to one another by means of external lines for oil and water. This makes the installation dimensions because of the required accessibility of the auxiliary devices and their external Lines and fasteners are disproportionately large and maintenance of the cylinder-crankcase unit is difficult and extremely complex.
  • the invention has for its object to eliminate these disadvantages, in particular to reduce the installation dimensions to a minimum and also to simplify maintenance. According to the invention, this is done in that all oil- and water-carrying parts of the elements of the cylinder crankcase mentioned, with the exception of the oil cooler filter unit, are made in one piece with the cylinder crankcase.
  • the invention is based on the knowledge that only through the one-piece design of all the above-mentioned parts with the cylinder crankcase can the structural dimensions of the cylinder crankcase be significantly reduced beyond the sum of the influences of the individual parts on the structural dimensions. If even one of the parts mentioned is not designed in one piece with the cylinder crankcase, this decisive reduction cannot be achieved.
  • the elimination of all external lines also simplifies maintenance considerably and increases operational safety at the same time. If necessary, only the oil cooler filter unit needs to be removed for maintenance. This also results in savings in machining and assembly costs, high rigidity of the cylinder crankcase, quieter operation and quick reaching of the operating temperature.
  • the individual elements can be cast with the cylinder crankcase and, if necessary, can also be machined.
  • the oil cooler filter unit which is flanged to the cylinder crankcase, all oil- and water-carrying parts are made in one piece with the cylinder crankcase. There are no external lines.
  • the spaces for accommodating the mass balance shafts together with counterweights can be cast with the cylinder crankcase.
  • the cylinder crankcase generally designated 1, consists of a single casting and has no external lines.
  • the end face of this cylinder crankcase 1 is designated by 2 and its flywheel side by 3.
  • a flange 4 is formed on the cylinder crankcase 1 and is used to fasten the oil cooler-oil filter housing (not shown).
  • the corresponding screws which engage the flange 4 are denoted by 5.
  • the cast oil suction channel 15 to the oil pump connects to the oil suction chamber 14 of the oil pump, and the oil bore 9 in the space of the oil cooler filter unit is connected to the oil pressure chamber 16 of the oil pump.
  • the main oil bore running in the longitudinal direction of the engine is designated by 17.
  • a thermostat housing 19 integrated into the suction side of the water pump, into which the water thermostat to be installed on surface 20 protrudes.
  • a water short-circuit duct 23 is provided between the cylinder head and the water pump.
  • the water jacket of the cylinder part of the cylinder crankcase 1 can be seen and designated 24. This water jacket is accessible from the outside via core holes 25.
  • the main oil bores 17 are arranged, which run in the longitudinal direction and supply the crankshaft bearings 27 with oil via branch bores 28.
  • FIG. 7 shows the transfer 8 of the de-taxed oil into the co-cast oil return 29 and the oil flow is illustrated by the arrow 30.
  • FIG. 8 shows the cast-in oil return channel 31 (front), which lies against the water jacket 24 of the cylinder.
  • 9 shows the oil return channel 32, which is also molded.
  • the arrangement of the oil and water pumps with respect to the work rooms and connecting lines is shown in FIG. 10.
  • the oil pressure chamber 16 of the oil pump and the transition 9 from the oil pressure chamber 16 into the oil cooler chamber of the oil cooler filter unit in the direction of arrow 36, as well as the suction chamber 34 of the water pump and the spiral housing 18 of the water pump, are also cast with the cylinder crankcase 1.
  • Fig. 11 the oil return channel, front, 31, the oil return channels, center, 35, the oil return channel, rear, 32, and the water short-circuit channel 23 can be seen.
  • 12 shows the oil descent at the front 31, the oil descent in the middle 35 and the transition 37 from the oil-water pump to the oil cooler of the oil cooler-oil filter unit.
  • the oil suction duct 15 and the suction chamber 34 of the water pump can also be seen.
  • the 13 shows the installation of the oil pump 38 and water pump 39 in the cylinder crankcase 1.
  • the oil pump 38 the shaft 40 of which has oil pump bearings 42 in the receptacle 41, is by means of the drive gear 43 driven.
  • the external gear of the oil pump is designated 44.
  • the gear wheels of the oil pump are located between the receptacle 45 and the oil pump cover 46.
  • the spiral housing 18 formed by the cylinder crankcase 1 is also molded with the latter.
  • the impeller of the water pump 39 is designated 39 '.
  • the lid of the water pump is highlighted with 47, the water pump seals with 48.
  • the internal combustion engine in question is provided with two 2nd order mass balancing shafts 12 and 13, which are housed in rooms 49 which are formed by the cylinder crankcase 1. This saves on additional components within the scope of the invention.
