Definitions

  • the invention relates to a reciprocating piston engine with a gear train emanating from the crankshaft to the camshafts and fluid pumps of the engine according to the preamble of claim 1.
  • Such a reciprocating piston engine is known from DE-Z Sonderbuch ATZ, Automobiltechnische Zeitschrift, 71st year, No. 9/12/1969 and 73rd year No. 5/1971.
  • An output shaft driven by the crankshaft for the clutch runs - seen in the vertical direction of the vehicle - below the crankshaft, parallel to it. It is driven by the crankshaft via a gear transmission which is arranged in a central plane between the two crankshaft ends.
  • the output shaft also drives the gear pumps and the oil pumps located in the engine crankcase.
  • An alternator which is screwed to the top of the engine housing, is used to power the engine.
  • the object of the invention is to design a gear train for the camshafts and the liquid pumps required for lubrication and cooling of the engine in such a way that the reaction torques occurring when the engine speed changes are largely balanced.
  • the gear train originating from the crankshaft lies in a central plane between the two ends of the crankshaft. It is thus achieved that the torsional vibrations in the wheel drive are reduced to a minimum. Because the waveform that results in the greatest deflection has a knot in the middle plane. By choosing this quiet zone for a center drive, the clutch, camshaft and fluid pumps remain largely free of torsional vibrations of the camshaft.
  • a reciprocating piston engine has two V-shaped cylinder rows 1 and 2, each with 6 cylinders.
  • an alternator 6 is arranged in the V-center 5. With tabs 7 it is screwed onto the cylinder heads 8.
  • Liquid pumps 12 are arranged on both long sides of the crankcase 9, which is composed of a lower part 10 and an upper part 11.
  • a pump set of the liquid pumps each consists of a water pump 13, an oil suction pump 14 and an oil pressure pump 15.
  • Two parallel camshafts are each mounted in the cylinder heads 8 of the two cylinder rows 1 and 2.
  • An intake camshaft 16 actuates the intake valves, an exhaust camshaft 17 the exhaust valves.
  • a gear drive 18 made of intermeshing spur gears is used, which is driven by a crankshaft 19.
  • the wheel drive 18 is arranged in a central plane 20 of the engine, which lies approximately midway between the front end 21 and the rear end 22 of the crankshaft 19.
  • the crankshaft 19 drives, with a pair of gearwheels 23, 24, an output shaft 25 which is parallel to it and which is connected to a clutch 26 arranged on the rear end of the engine.
  • a gear 27 of the output shaft 25 meshes with a right drive wheel 28, with which the camshafts and liquid pumps located to the right of the V center 5 are driven.
  • a coaxial additional gear 29 of the output shaft 25 is in engagement with a left drive wheel 30 for driving the camshafts and liquid pumps arranged on the left of the V center 5.
  • Both drive wheels 28, 30 consist of a larger drive gear 31 meshing with the gear 27 and 29 of the output shaft 25 and a smaller drive gear 32, with which the camshafts 16, 17 and liquid pumps 12 are driven.
  • the intake camshaft carries a gear 34
  • the exhaust camshaft 17 carries a gear 35, both of which are driven together by the drive gear 32 via an upper intermediate gear 33.
  • the same drive gear 32 meshes with a lower intermediate gear 36, which drives a pump gear 37 with which the water pump 13, the oil pump 14 and the oil pressure pump 15 are driven together.
  • the alternator 6 is provided with an intermediate shaft 38 which is arranged coaxially and in a rotationally fixed manner with respect to the output shaft 25 and via one of the latter outgoing belt drive 39 driven.
  • the belt drive lies between the front 40 of the engine and a transverse wall 41 of the vehicle body.
  • the intermediate shaft 38 is designed as a thin, resilient torsion bar in order to weaken load impacts in the drive train.
