Definitions

  • the invention relates to a reciprocating piston engine with two rows of cylinders arranged in a V-shape 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.
  • the pumps are mounted on the outside of the motor housing, they are optimally accessible for assembly and repair work. Since they are arranged just above the bottom part of the crankcase, they contribute in a desirable manner to lowering the center of gravity of the engine. If identical pump sets consisting of water pump and oil pump are installed on both long sides of the crankcase, a symmetrical construction of the engine can be achieved.
  • a reciprocating piston engine has two V-shaped rows of cylinders 1 and 2, each with 6 cylinders.
  • a housing of the reciprocating piston engine is composed of a lower crankcase 3 and two head housings 4 and 5 screwed to its upper side and enclosing the valve drives of the two rows of cylinders. With its bottom part 6, the crankcase 3 is screwed to the bottom 7 of the vehicle frame.
  • a pump set 9 is screwed onto the outside of the crankcase 3, just above its base plate 6, on the right long side 8, as seen in the direction of travel A, and a pump set 11 on the left long side 10.
  • Both pump sets 9 and 11 are designed the same. They are arranged symmetrically to the central longitudinal axis 12 of the motor and to the central plane 13 lying transversely and pointing in the motor height direction. The central plane 13 lies exactly in the middle between the front end 14 and the rear end 15 of the crankshaft 16.
  • the gear drives 17 and 18 are each formed from a crankshaft gear 19, an idler gear 20 and a pump shaft gear 21.
  • Both pump sets 9 and 11 consist of a water pump 22, an oil suction pump 23 and an oil pressure pump 24, which are arranged side by side and coaxially in this order and are driven by the pump shaft gear 21.
  • the housings of the pumps 22, 23, 24 and the oil filter 26 are screwed together.
  • the water pump 22 of the right pump set 9 is located behind the central plane 13.
  • the pump shaft gear 21 sits between the water pump 22 and the oil suction pump 23, which sucks in the lubricating oil from the crankcase 3.
  • the oil pressure pump 24 of the right pump set 9 With the oil pressure pump 24 of the right pump set 9, the engine half lying in front of the central plane 13 is supplied via a connecting elbow 27, and the rear engine half with the oil pressure pump 24 of the left pump set 11 with lubricating oil.
  • the water pump 22 of the left pump set 11 supplies the entire left row of cylinders 2, the right water pump 22, the right row of cylinders 1 with cooling water.
  • a gear drive from the crankshaft 16 to a drive shaft 30 driving the clutch 29 and the drive wheels (not shown) for the camshafts 28 are also arranged in the central plane 13.
  • the output shaft 30 running parallel to the crankshaft 16 leads to the clutch 29 located on the rear end face 31 of the engine.
  • Another gear drive leads from the crankshaft 16 to an intermediate shaft 33, from which an alternator 34 arranged on the front end face 32 of the engine is driven with an end belt drive 35.
  • the alternator 34 is located in the V center between the two rows of cylinders 1 and 2. This space can be used for the alternator 34, since the installation of separate intake ports 36 makes it unnecessary for each cylinder to have a common air intake system which is arranged in the V center.
