Definitions
- the present invention describes a reciprocating piston engine with rocker arm valve control according to the preamble of independent claims.
- the invention for example closer to a 2-cylinder in-line engine explained, but applies to reciprocating engines with any Number of cylinders.
- FIG. 1 schematically show four different valve controls, as described, for example, in the book Automotive paperback Bosch "VDI-Verlag, 19th edition, shows.
- One possible embodiment is the rocker arm valve control shown in Fig. 1, Fig. 3.
- This type of valve control is used today especially in engines with low friction
- the main disadvantage of this type of construction is the greatly increased effort for machining and assembling the valve train, the complex maintenance, and the increased space requirement in the longitudinal direction of the cylinders.
- 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 also 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, not shown cylinders 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 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 Recordings 16 placed and a mounting shaft 17 inserted can be.
- the cylinder head cover 14 with the corresponding machined side surfaces 21 serves the lateral Fixing the assembly shaft 17 for the camshaft 10.
- 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 assembly shafts 13 inserted and fixed by the side surfaces 23 on the cylinder head cover 14 become.
- 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 there are no bearings 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 enables. Due to the possibility of the cylinder head cover is not to be used to fix the assembly shafts 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 be lubricated enough.
- 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.
