Definitions

  • the invention relates to a device for setting the control times on an internal combustion engine according to the preamble of claim 1.
  • a device in the form of a control box in which a chain drive is used is known, with the help of which the synchronous position of the camshaft is determined independently of a specific position of the crankshaft.
  • the housing box contains the driving and the driven pinion as well as the chain, which engages in the pinion and thus secures the presetting of the control, so that the injection pump shaft and the camshaft are in their desired position relative to the crankshaft be coupled with the respective pinions.
  • the sprockets freely arranged in the housing are held in their position by means of ribs which are adapted in the shape of a circular arc to the contour of the sprockets.
  • the housing also contains detachable, angular positioning parts, which have protruding cylindrical elevations with ribs, and which interact with the pinions and their respective partial grooves to fix the angular position of the pinions.
  • control box The assembly of the above control box is complicated and has to be opened with every readjustment. Incorrect settings for the releasable positioning parts cannot be ruled out, since these can occur when installing and removing the parts, and impairing the exact setting of the driving and driven shafts to one another . In addition, the control box must be resealed after each removal or adjustment.
  • the invention has for its object to propose a device for adjusting the timing in an internal combustion engine, which is easy to use and meets the requirement for exact position maintenance of the driving crankshaft and the driven camshaft during the adjustment work.
  • the camshaft and the crankshaft are each immovably held in a defined position by an adjusting pin.
  • the crank The shaft is held in place by the adjusting pin and by the stop sleeve screwed into the crankcase.
  • an adjusting pin suffices to lock it, which is screwed through the crankcase or through the housing provided specifically for the camshaft and engages in the camshaft within a bore provided for this purpose.
  • the tips of the adjusting pins protrude smoothly into the respective bores of the camshaft and crankshaft, but without play, in order to counteract any rotation of the shafts.
  • the part of the adjusting pin located within the crankcase on the camshaft and that of the stop sleeve on the crankshaft is reduced in diameter.
  • the beginning of the stepped part is threaded and screwed into the crankcase.
  • the offset end face on both parts lies against the crankcase and holds the respective part against tilting movements.
  • the end part of the stop sleeve is also in the installed state on the Crankshaft flattened point and forms an additional safeguard against rotation of the crankshaft.
  • Fig. 1 "a” shows an axial section on a crankcase 1, in which a crankshaft 7 is embedded.
  • a stop surface 23 is provided on the side of a crank web, with a bore 21 which is axially aligned with a threaded bore 24 on the crankcase.
  • the adjusting pin 20 is screwed in through the threaded bore 24 on the crankcase until its stepped surface 25 rests on the crankcase and its tip engages in the bore 21.
  • the crankshaft can thus be held in the desired position.
  • the outer part of the setting pin is knurled to enable it to be installed and removed.
  • Variant "b” differs from variant “a” only in that the bore 22 into which the adjusting pin 20 engages has more play than the bore 21, which is easier and more economical to manufacture.
  • Figure 2 shows in axial section a crankcase part 1 of an internal combustion engine with a camshaft 6 and the crankshaft 7 mounted therein.
  • the crankcase has a bore 4 at the level of the camshaft, the initial part 4 'is provided with an internal thread. Also at the level of the upper part of the crankshaft, a threaded bore 15 is provided in the crankcase.
  • the camshaft has a bore 5 which is flush with the bore 4 when the camshaft is brought into the position which is decisive for the adjustment of the timing.
  • the setting pin 2 is pushed and tightened on the threaded part 4 '.
  • the tip of the stepped part 3 of the adjusting pin engages in the bore 5 and holds the camshaft 6 in its position immovably.
  • the end of the adjustment pin When screwed in, the end of the adjustment pin snaps into the camshaft bore smoothly and without play and locks the camshaft firmly in the position intended for adjustment. Increased security against twisting is achieved by creating the offset Level of the adjusting pin on the crankcase reached.
  • the adjustment pin is knurled or provided with a hexagon head or a slot to facilitate the installation or rotation of this part in the crankcase.
  • a threaded hole is provided on the crankcase at the level of the crankshaft upper part, through which a stop sleeve 9 with an outer diameter is screwed.
  • the threaded part 11 of the stop sleeve lies at the beginning of the offset piece and is dimensioned such that the stop sleeve bears in the installed state with the offset surface on the crankcase outer wall, while at the same time the end part lies on the flattened area around the threaded bore 14 on the crankshaft 8. This ensures the highest level of security against torsion.
  • any macro movement that may occur due to the force of the crankshaft can be switched off by magnetically activating the tip of the setting pin 13 within the threaded bore 14.
  • the adjusting sleeve is also knurled or provided with a hexagon head to facilitate installation.
  • the driving crankshaft and the driven camshaft are brought into immovable position by the two adjusting pins and the stop sleeve.
  • the power transmission Element, chain or wheel drive, can then be attached to the immovably fixed shafts.
  • Block or distributor injection pumps can also be set correctly in the same way with a fixed blocking of the intended setting position.
  • the stop pins and the stop sleeve are removed and the openings on the crankcase are closed with a locking screw.
