Definitions

  • the invention relates to a camshaft drive for a V-type internal combustion engine according to the preamble of the main claim.
  • DE-3347638 C discloses a generic internal combustion engine with rows of cylinders arranged in a V-shape, the two overhead camshafts of which are each driven by a single, double-row timing chain. Due to the overlap of the drive wheels of two adjacent camshafts and due to the offset of the rows of cylinders to one another in the longitudinal direction of the internal combustion engine, no identical camshafts can be used.
  • the invention has for its object to provide a camshaft drive in a generic internal combustion engine, which has the smallest possible number of different components and thereby makes optimal use of the available space.
  • This problem is solved with the features of the main claim.
  • This camshaft drive enables the use of identical camshafts for both cylinder rows in internal combustion engines with cylinder rows arranged at any angle in a V-shape.
  • This advantage applies in particular to internal combustion engines with several camshafts per row of cylinders.
  • Identical drive wheels designed as identical parts are arranged on all camshafts.
  • the use of identical camshafts is achieved by an offset between the driven wheels arranged on the crankshaft and assigned to the cylinder rows, which offset corresponds to the offset of the cylinder rows to one another.
  • the space thus created between the driven wheels on the crankshaft is used to arrange a gearwheel which drives a spaced-apart crankshaft or an oil pump arranged coaxially with this gearwheel.
  • FIG. 1 shows a view of a V-type internal combustion engine
  • FIG. 2 shows a section along the line II-II according to FIG. 1
  • FIG. 3 shows a schematic section along the line III-III according to FIG. 1.
  • An internal combustion engine 3 provided with two cylinder rows 1, 2 arranged in a V-shape relative to one another has a crankshaft 4 and overhead camshafts 5, 6 and 7, 8 assigned to the cylinder rows 1 and 2, respectively.
  • the two rows of cylinders 1, 2 have an offset H to one another in the longitudinal direction L of the internal combustion engine 3.
  • a first and a second driven gear 9 and 10 are arranged at a distance A from one another which is approximately the same as the offset H.
  • the driven wheels 9 and 10 drive the camshafts 5, 6 and 7, 8 by means of chains 11 and 12 respectively.
  • the camshafts 5 to 8 each have a drive wheel 13, which is provided with a spacer sleeve 17 and is designed as identical parts.
  • the first drive wheels 13 assigned to a row of cylinders 1 are mounted on the camshafts 5, 6 in such a way that the spacer sleeves 17 face this row of cylinders 1.
  • the spacer sleeves 17 of the second drive wheels 13 are mounted facing away from the other row of cylinders 2, i.e. these second drive wheels 13 are arranged offset by 180 degrees with respect to the first drive wheels 13.
  • a housing 22 of this oil pump 21 is arranged coaxially with the gear 20.

Abstract

L'entraînement d'arbre à cames pour un moteur à combustion interne (3) avec disposition des cylindres en V présente sur le vilebrequin (4) deux pignons de sortie (9, 10), dont chacun est associé à une rangée de cylindres (12). La distance (A) entre les pignons de sortie correspond au déport (H) des rangées de cylindres entre elles et permet l'utilisation de pièces identiques.
