Definitions

  • the invention relates to a piston cooling for internal combustion engines.
  • a spray nozzle made of a bent tube is positioned by means of a bracket and a screw on the inside of a crankcase so that a certain area of the piston crown is molded.
  • the invention has for its object to make the production and assembly of the spray nozzles rational.
  • the turned part can be produced fully automatically by machining cost-effectively and in consistent quality.
  • Figure 1 shows in cross section a crankcase 1 with oil supply holes 2a, 2b which are integrated in a pressure circulation lubrication and which penetrate the crankcase 1 in the longitudinal direction.
  • About holes 3a, 3b is the crankshaft bearings Lubricating oil supplied.
  • the lubricating oil is also used for piston cooling.
  • the piston cooling takes place in a known manner by spray nozzles 4 which are arranged in L Lucassbohrept5 the bulkheads 6, which are located between the crank chambers.
  • the supply of the oil to the spray nozzle 4 takes place from the oil supply bore 2b via the bore 3a for the bearing lubrication and a bore 7.
  • the holes 3a and 7 are interconnected by a recess 8.
  • the spray nozzle 4 generates an oil jet 9 which is directed against an underside of a piston crown.
  • a spray nozzle 4 is shown in detail in FIG.
  • the spray nozzle 4 is made as a turned part.
  • the spray nozzle 4 has a central blind bore 10, which is closed by a plug 11.
  • the supply of cooling oil via a central oil supply hole 12. This is after installation in the longitudinal bore 5 in coincidence with the bore 7 in the bulkhead 6. (Fig. 1)
  • the cooling oil is sprayed by means of the injection holes 13a, 13b.
  • the advantage of the spray nozzles 4 according to the invention is to be seen in the fact that they can be produced solely by machining, ie by means of automatic lathes. In the manufacture of mass-produced vehicles, which undoubtedly represent vehicle engines, the cost issue is crucial.
  • FIG. 3 shows a view of the crankcase 1 from the oil pan side.
  • Each of the bulkheads 6 has a longitudinal bore 5. These longitudinal bores 5 penetrate the bulkhead walls 6 coaxially and run parallel to the center line of a crankshaft.
  • the spray nozzles 4 are installed oriented so that the ejected from the spray holes 13a, 13b oil jets 9 (Fig. 1) meet the intended target.
  • the tool consists essentially of a hydraulic piston-cylinder unit (KZE) 14.
  • the cylinder 15 is rigidly connected to a positioning arm 16 - for example a robot - connected.
  • two axially freely movable piston 17 a, 17 b are arranged in the cylinder 15 .
  • the piston 17a has an end piece 18 which engages over the spray nozzle 4a already installed in a bulkhead wall 6a in order to support itself.
  • a pressure can build up in the cylinder 15 which moves the second piston 17b, which presses the spray nozzle 4b into the bore of the second bulkhead 6b, so that it is reliably protected against displacement and rotation.
  • Due to the freely movable piston 17a, 17b in the cylinder 15, the positioning arm 16 can be held torque-free despite the very high forces for pressing in the spray nozzles 4a, 4b.
  • the installation can thus be fully automatic by means of robots.
