Definitions

  • the invention relates to an internal combustion engine according to the preamble of claim 1.
  • the invention is therefore based on the object of a two-row internal combustion engine with the most compact possible To create dimensions and behavior optimized with regard to torsional vibrations.
  • the drive of the intermediate shaft takes place from the end section of the crankshaft which has low torsional vibrations and carries the flywheel, then the torsional vibrations transmitted to the intermediate shaft are negligible.
  • the space-saving arrangement of the two drive connections to the camshafts is not critical in terms of vibration.
  • the position of the intermediate shaft below the crankshaft offers good space utilization of the volume that is required anyway for the arrangement of the oil suction basket, oil pan, etc.
  • An arrangement above the crankshaft would disadvantageously restrict the installation space urgently required for an auxiliary unit arrangement in the V between the cylinder rows. With a V-angle of 180 °, it would unnecessarily increase the overall height of the motor.
  • a symmetrical arrangement of the intermediate shaft below the crankshaft creates the prerequisite for the same drive behavior to the camshafts of both cylinder rows.
  • the overall length of the internal combustion engine in the longitudinal direction of the crankshaft can be further reduced if the drive of the intermediate shaft is arranged between the second drive connection and the flywheel.
  • a drive of two camshafts per cylinder bank can be realized if these two camshafts are connected to one another via a gear, for example gearwheels or chains, arranged approximately centrally along their longitudinal extent.
  • a gear for example gearwheels or chains, arranged approximately centrally along their longitudinal extent.
  • the overall length of the internal combustion engine remains unchanged, as does the overall arrangement of the drives.
  • the arrangement according to the invention can be used to drive an auxiliary unit, e.g. an oil pump.
  • an auxiliary unit e.g. an oil pump.
  • the end region of the intermediate shaft remote from the flywheel carries a rotary drive, for example in the form of an angular pin, which engages drivingly in an oil pump. There is no separate drive for the oil pump.
  • the prescribed arrangement can be implemented in the shortest extent with respect to the overall length if, starting from the flywheel, first the drive of the intermediate shaft, then the second drive connection for one camshaft, then the first drive connection for the other camshaft and finally the rotary drive is arranged.
  • the drive of the intermediate shaft, the drive connections to the camshafts and the gears arranged between adjacent camshafts can e.g. each be made up of chains and gears.
  • An internal combustion engine has two rows of cylinders with a V angle of 180 °.
  • a crankshaft 1 is part of a crank mechanism. 1 shows the piston 2 and connecting rod 3 of only one row of cylinders to illustrate the invention.
  • the crankshaft 1 carries a flywheel 5 at an end section 4 and adjacent to it a drive 6 for an intermediate shaft 7 running below the crankshaft 1 parallel to its longitudinal axis AA.
  • This longitudinal axis AA and the corresponding axis BB of the intermediate shaft 7 lie in a plane of symmetry EE, to which the pistons 2 of the internal combustion engine move perpendicularly.
  • a first drive connection 9 for a camshaft 10 of a row of cylinders is arranged on an end region 8 of the intermediate shaft 7 remote from the flywheel. Adjacent to the drive 6, the intermediate shaft 7 carries on its end region 11 near the flywheel a second drive connection 12 for a camshaft 13 of the other row of cylinders.
  • Each row of cylinders has a second camshaft 14, 15, which is driven by the respective first camshaft 10, 13 with the interposition of a gear 16.
  • the gears 16 are arranged approximately centrally with respect to the longitudinal extension of the camshafts 10, 13, 14, 15 parallel to the crankshaft 1.
  • the end portion 8 of the intermediate shaft 7 remote from the flywheel carries a rotary drive 17 for an oil pump 18.
  • This rotary drive 17 is designed as a form-fitting plug connection such that a shaft 19 of the oil pump 18 lies coaxially with the longitudinal axis A-A.
  • the drive connections 9 and 12 are each provided on their load strand with a tensioning rail 21 acted upon by a hydraulic tensioner 20 and on their lost strand with a slide rail 22.
