Definitions

  • the invention relates to a reciprocating piston engine for a motor vehicle 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.
  • An alternator which is screwed to the top of the engine housing, is used to power the engine.
  • the alternator designed as a three-phase generator on the engine housing in such a way that a symmetrical weight distribution of the engine can be achieved with respect to the longitudinal axis of the engine, that the center of gravity of the engine is as low as possible and that the alternator is driven correctly.
  • the characteristic features of claim 1 serve to solve this problem. If the alternator is located in the V center, it is arranged symmetrically to the longitudinal axis and contributes to an even weight distribution of the engine. Since it is adapted according to claim 2 with a narrow radial distance to the outer walls of the V-neck, its center of gravity can have a minimal geodetic height. As a result of its position vertically above the crankshaft, it can be driven directly by it using simple constructional means.
  • the alternator is driven by an intermediate shaft designed as a resilient torsion bar, which is driven by it lying above the crankshaft.
  • a reciprocating piston engine has two V-shaped cylinder rows 1 and 2, each with 6 cylinders.
  • a suction port 3 leads to each cylinder.
  • a three-phase alternator 6 is arranged in the V-section 4 in the V-center 5. Its housing 7 is screwed with tabs 8 to the right cylinder row 1 and left cylinder row 2, as seen in the direction of travel A.
  • the outer walls of the motor housing 9 which delimit the V-neck 4 are shaped cylindrically in accordance with the cylindrical housing 7 of the alternator 6. They surround it with a small radial distance s.
  • One end face 10 of the housing 7 of the alternator 6 is flush with the front end face 11 of the motor housing 9, which is opposite a transverse wall 12 of the vehicle body at a short distance.
  • a belt drive 13 is arranged on the end faces 10 and 11 from an intermediate shaft 14 to the shaft 6 'of the alternator 6.
  • the intermediate shaft 14 is non-rotatably in an output shaft 15 for clutch 16.
  • the output shaft 16 is driven in the central plane 17 by the crankshaft 18 with a gear set 19.
  • the central plane 17 lies approximately centrally between the front end 20 and the rear end 21 of the crankshaft 18.
  • the translation from the crankshaft 18 to the output shaft 15 and from the intermediate shaft 14 to the shaft 6 'of the alternator 6 is in each case approximately 1: 1, so that the alternator 6 rotates at approximately the same speed as the crankshaft 18. If such a piston engine is used as a racing engine , the maximum crankshaft speed is approx. 14,000 rpm.
  • the intermediate shaft 14 is designed as a resilient torsion bar so that shocks in the power transmission are reduced. In addition, the vibrations are weakened by the belt drive 13.
  • the right pump set 24, which is arranged on one long side of the motor housing, and the left pump set 25, which is arranged on the other long side of the motor, are driven via the output shaft 15 with left wheel sets 22 and right wheel sets.
  • the pump sets 24 and 25 each consist of a water pump, an oil suction pump and an oil pressure pump.
