Definitions
- the invention relates to a carrier module for an OHC valve train of an internal combustion engine, with two upright and mutually spaced support walls, which are connectable at their Oberstirnen with a cylinder head cover and at their lower forehead with a cylinder head and at least one main and secondary bore for supporting a Cam and valve actuating lever shaft between them.
- carrier modules are, for example, in 1-cylinder motorcycle engines with 2V technology in use and made of cast aluminum (see valve engine Honda engine KRM / KVS, installed in Hyundai CG 150 Titan (Brazil)).
- the levers for actuating the two gas exchange valves sit on separate shafts.
- Such a carrier module builds comparatively massive and takes up unnecessary space.
- the functional surfaces of the carrier module such as, for example, the bores for the cam and valve actuation shaft (s), are subsequently finely machined.
- the production costs and the - costs are increased, which comes especially in mass production to fruition.
- each support wall consists of two support plates which are uniformly connected to either the upper or lower forehead by a transverse wall, with opposing inner support plates are connected by a transverse plate which extends on a opposite side of the transverse walls.
- a lightweight and compact carrier module is particularly, but not exclusively, available for motorcycles, boats, or minisite engines.
- a module should be used in 1-cylinder engines.
- the carrier module according to the invention is designed to accommodate only a central, short-throwing camshaft and at least one flanking valve actuation camshaft.
- lever shaft wherein preferably an inlet and a Auslisterventilbetuschistshebelwelle are provided and also more than one camshaft can be used.
- the protection of this invention also extends to cam and valve actuation lever shaft (s) and levers mounted thereon.
- cam and valve actuating lever shaft (s) can also run directly in their respective bores of the support plates, however, these bores should preferably be provided with separate sleeves which, for example, are pressed in and can also accommodate roller bearings. It is useful in this case, the support plates on the example. Deep-drawn sleeves to connect with each other, so that is stiffened at the same time about this, the entire structure. Possibly.
- the cam and valve actuating lever shaft (s) may also be mounted only in the opposing inner support plates. Alternatively or additionally, the support plates can be stiffened by other webs outside the holes.
- a simple connection possibility of the carrier module with the cylinder head is another subject of the claim. Accordingly, protruding from the lower end of at least one support wall at least one integrally connected tab orthogonal preferably to the outside.
- the tabs can be provided with holes for screwing the carrier module with the cylinder head and holes for inserting dowel pins.
- a cylinder head cover which may also contain oil channels with spouts, with the carrier module.
- the two Oberstirnen / transverse walls on the one hand directly have holes for screwing / pinning with the cylinder head cover.
- At least one lug can protrude orthogonally from the upper face / transverse wall of at least one supporting wall, which then has holes for screwing / pinning.
- a riser for lubricating oil in the direction of the cylinder head cover.
- This tube may be made of plastic or other lightweight material and with the support wall, for example. Snapped / clipped and be provided with a check valve.
- FIG. 1 shows a three-dimensional side view of a carrier module with mounted valve actuating lever shafts and rocker arms thereof and a mounted camshaft;
- FIG. 2 shows a three-dimensional view of the carrier module according to FIG. 1 from above and FIG.
- the support module 1 has two upright and mutually spaced support walls 2.
- Each support wall 2 consists of two contrast less spaced support plates 10, 1 1, which are connected at their Oberstirnen 3 by transverse walls 12.
- Each support wall side thus results in cross-section an inverted U-profile.
- the opposing inner support plates 1 1 go on Unterstirnen 4 in a transverse plate 13 on.
- the ultimately doubled support walls 2 with the transverse plate 13 in cross section form an upright U-profile.
- the aforementioned Oberstirnen 3 have not shown holes or tabs for screwing with a cylinder head cover.
- From the Unterstirnen 4 of the outer Support plates 10 are integrally connected tabs 17 for screwing the support module 1 with a cylinder head orthogonal to the outside.
- the support plates 10, 1 1 extend central main holes 5 with thermoforming sleeves attached thereto as stiffening webs 15.
- the camshaft 7 is mounted end.
- the sleeve area can be limited and completed by an end shield o. The like. Outside.
- thermoforming sleeves are pressed as stiffening webs 14, which in turn bridge the support plates 10, 1 1 and in which valve operating lever shafts 8, 9 are mounted.
- the valve operating lever shafts 8, 9, which does not appear from the drawing, the support walls 10 project slightly beyond the front side and be provided with threaded portions for nuts for screwing to the support walls 2.
- FIG. 1 From Figure 1 also shows that the transverse plate 13 has a central window 16, in which cam 21 of the camshaft 7 can dip.
- a separate oil riser 20 made of plastic is clipped in the rear end face region 19 of the support wall 2, which can be seen here on the right, which is shown in greater detail in FIG.
