Definitions

  • the present invention describes a reciprocating piston engine with rocker arm valve control according to the generic term of Claim 1.
  • the invention is exemplary a 2-cylinder in-line engine explained in more detail applies for reciprocating engines with any number of cylinders.
  • valve controls e.g. according to Figure 1, the schematically four different valve controls, like them for example in the book Kraftfachtechnisches Taschenbuch Bosch "VDI-Verlag, 19th edition, to be described shows.
  • a possible embodiment is that in Fig. 1, Figure 3, shown rocker arm valve control. That kind of Valve control is used particularly today in engines used where low friction and low Height in the foreground.
  • a disadvantage of this design is the greatly increased effort for editing and Assembly of the valve train, the complex maintenance, as well as a increased space requirement in the longitudinal direction of the cylinders.
  • GB-A-2 157 770 discloses one conventionally on rolls or plain bearing mounted camshaft, the invention this document on a decompression device for a motorcycle is aimed.
  • DE-C-801 241 discloses a rotary adjustable Eccentric bushing around which an axially adjustable and rotatable hub of the rocker arm device engages.
  • FIGS 2 to 5 schematically show parts of the drive a reciprocating piston engine according to the invention, with piston 1, of which only one is shown, which is on the connecting rod 2 attached and via the crank pin 3 with the crankshaft 4th are connected.
  • a balance shaft 5 can be seen with sprocket 5K, one directly with the crankshaft connected chain wheel 6, a chain tensioning wheel 7 to the chain 8 to be able to tension the camshaft sprocket 9 drives, which enables the rotation of the camshaft 10, which in turn actuates the rocker arm 11, which the move indicated valves 19 along the valve axis 12.
  • One in the embodiment as a so-called in-line engine has internal combustion engine shown in reciprocating piston design two parallel cylinders, not shown, in which the pistons 1 run up and down.
  • the one below the cylinder arranged crankshaft 4 has two crank pins 3, each of which a connecting rod 2 is mounted.
  • Each of the connecting rods is connected to a piston 1 in the respective cylinder runs up and down.
  • the camshaft 10 is driven by a Camshaft sprocket 9, which is between the There are pairs of cams for the individual cylinders. in the Embodiment is this camshaft sprocket in the middle of the camshaft, but it can be in another version also offset from the center be arranged.
  • the camshaft 10 is through the timing chain 8 on the Camshaft sprocket 9, the chain tensioning wheel 7, the counter-rotating balance shaft 5 with Balance shaft sprocket 5K and the crankshaft sprocket 6 driven by the crankshaft 4.
  • a further possible execution of the camshaft drive includes a version with toothed belt and Toothed belt wheels instead of chain and chain wheels.
  • Figures 6 and 7 illustrate the installation of the camshaft 10 and the Rocker arm 11 directly into the cast on the cylinder head 24 Recordings 15 and 16. This has the advantage of a very simple editing and a very simple assembly of the Camshaft and the rocker arm.
  • Figures 6 and 7 show only cutouts from the cylinder head 24 and cylinder head cover 14, in which all the organs described are arranged.
  • the assembly is shown below using the example of the camshaft 10 explained in more detail and the advantages listed in detail.
  • the present invention must be the pre-cast Recordings 16 in the cylinder head 24 for the camshaft 10, the is a hollow shaft, only to the desired shaft size be drilled so that those with the inside Roller bearings 20 provided camshaft 10 between the Recorded 16 and the serving as an assembly shaft Camshaft axis 17 can be inserted.
  • the Cylinder head cover 14 with the correspondingly machined Side surfaces 21 are used for lateral fixation of the Camshaft axis 17.
  • rocker arm 11 are also designed as hollow shafts with roller bearings 22 and are placed between the receptacles 15 according to FIG. 7, whereupon the rocker arm axles serving as assembly shafts 13 inserted and through the side surfaces 23 on Cylinder head cover 14 are fixed.
  • An advantage of the invention is therefore a very simple one Machining of the valve train and a very simple assembly the camshaft and the rocker arm.
  • Another advantage of Invention is the use of roller bearings for storage of camshaft and rocker arms, which makes them very low Friction losses are made possible and no pressure oil supply is needed.
  • Another great advantage of the invention is that none additional screw connection or other fastening of Bearing blocks is needed. Due to the special design of the cylinder head cover are no bearings in it needed. In addition, there are no interrupted ones Sealing surfaces between the cylinder head cover and the cylinder head and it becomes a very simple seal on the candle hole allows. Due to the possibility of the cylinder head cover to fix axes 13 and 17 is not necessary further securing the camshaft and the rocker arm required. The invention also makes maintenance like Valve clearance control and setting are significantly simplified and camshafts and rocker arms can be extremely simple be replaced.
  • FIG. 8 shows a variant for the execution of the recordings, in particular the rocker arm shaft receptacles, the cylinder head shown in perspective is. It has been shown that certain models and heavy-duty castings for the Rocker arm shafts do not meet the requirements.
  • the cast receptacles 15 according to Figure 7 can in this Cases according to the embodiment of Figure 8 by recordings 15A steel to be replaced in pairs and on Cylinder head 24 are screwed directly. The remaining Advantages like the cast recordings are complete maintained and the assembly of the rocker arm shafts takes place on the same way.
  • the chain tensioning wheel 7 is in line with the Crankshaft sprocket 6 arranged so that both a sufficiently large wrap angle for all shafts than also a reversal of the direction of rotation for the balancer shaft 5 is achieved.
  • the chain tensioning wheel 7 can be used to reduce the Friction on roller bearings and only on the spray oil the chain must be lubricated sufficiently.
  • This measure of the invention also allows a very simple and compact construction of the valve train.
  • Invention with toothed belt possible.
  • the Sprockets replaced by toothed belt wheels.
