Definitions
- the invention relates to a support module for an OHC valve train of an internal combustion engine, with two upright and mutually spaced support walls, which are connectable in the section of their Oberstirnen with a cylinder head cover and the section of your Unterstirnen with a cylinder head, wherein in the support walls at least one camshaft and at least one lever axis is mounted with one or more cam follower levers.
- Such carrier modules are, for example, in 1-cylinder motorcycle engines with 2V technology in use and made of cast aluminum (see valve engine Hyundai 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.
- the holes for cam and valve actuation shaft (s) are subsequently machined finely.
- the production cost and the - costs are increased, which comes especially in mass production to fruition. It is an object of the invention to create a carrier module without the aforementioned disadvantages.
- this object is achieved in that the supporting walls are integrally bridged at their Oberstirnen by a cross bar, projecting integrally from the lower end of each support wall, a leg for direct connection of the carrier module with the cylinder head and wherein the support walls with the crossbar and the legs punching-bending technology made of sheet steel are shown.
- 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 steel sheet (board / tape) are also other lightweight materials such as aluminum sheet, also packaged or otherwise reinforced, plastics, fiber or particle-reinforced, etc. to offer.
- the carrier module according to the invention is designed to receive only a central, short-building camshaft and for receiving at least one lever axis flanking the camshaft, wherein preferably an inlet and an outlet lever axis each mounted thereon cam followers (at least one per axle) are provided and more than one camshaft can be used.
- the protection of this invention extends only to the carrier module with holes in the support walls with the possibility of receiving cam and valve actuating lever shaft (s), therefore without the latter components.
- the carrier module according to the invention ultimately has either a reverse U-like cross-section with projecting legs or, in the case of the latter facing each other, a box-like design.
- the legs can be connected or separated by a longitudinal gap. This variant takes up very little space.
- bead-like depressions or the like are proposed in at least one longitudinal bending edge of the carrier module. It is preferred in this case to provide all longitudinal bending edges with such beads. This solution stiffens the entire structure. Possibly. Thinner sheets can be used.
- the base plate has, as further proposed, in the region of its edges openings, which may be, for example, punched holes.
- the openings serve, for the mounting case of the carrier module on the cylinder head, an engagement of, for example, screws or centering pins.
- the carrier module can, but need not, be bolted to the cylinder head cover over the crossbeam.
- the proposed ⁇ lslessnessrschreibchen may consist of plastic or other lightweight material and with the respective support wall, for example. Snapped or clipped and be provided with a check valve.
- camshaft (s) and lever axis (s) can also run directly into bores of the support plates. It is more advantageous, however, to provide these holes with separate sleeves, which, for example, are pressed and can also take bearings.
- FIG. 1 shows a spatial side view of the carrier module
- FIG. 2 shows a spatial view of the carrier module from above.
- the support module 1 has two upright and mutually spaced support walls 2, which are integrally connected in their Oberstirnen 3 by a crossbar 10.
- the latter can be connected to a not shown cylinder head cover and has two stiffening step portions 17, 18 (see also Figure 2), wherein the middle step portion 18 is like a roof lifted from the laterally limiting step portions 17.
- the legs 1 1 have in the region of their outer edges 19 punched openings 20 for screwing the carrier module 1 with the cylinder head.
- a camshaft 5 is mounted, which is flanked by two lever axes 6, 7, each with a cam follower lever 8, 9.
- the latter are present as each of a cam of the camshaft 5 acted upon rocker arm, wherein according to Figure 2, the lower cam follower lever 8 is an intake rocker arm and the upper cam follower lever 9 is a Auslrawkipphebel.
- all longitudinal bending edges 12, 13, 14, 15 of the carrier module 1 each have two bead-like indentations 16, which are advantageously introduced during or before the bending of the carrier module 1 thermoforming or embossing technology.
- Figure 2 best discloses that on a support wall 2 from the bottom to the top end 4, 3 leading ⁇ lsiererschreibchen 21 is clipped. This serves to forward lubricating oil in the direction of the cylinder head cover.
