Embodiment Construction

[0014] Shown is a lightweight support module 1 made of steel sheet metal using stamping and bending technology for an OHC valve train of a single-cylinder motorcycle internal combustion engine.

[0015] The carrier module 1 has two upright carrier walls 2 spaced apart from each other. The carrier wall can be connected at its upper end 3 to the cylinder head via one-piece bent tongues 20 (one tongue 20 on each side). The carrier wall 2 has at its lower end 4 a foot 15 bent from the carrier wall with bore holes 18 (two on each side) through which the carrier module 1 can be screwed to the cylinder head of the internal combustion engine. catch.

[0016] As can be seen, each carrier wall 2 has a central main bore 5, in which a camshaft 6 with two lifting cams (1 for intake and 1 for exhaust) is thus accommodated 5 in. The main bore 5 has a rolling or plain bearing (not shown) for carrying the camshaft 6 and is closed on the outside in each case by a cover, which thus protects t...

Abstract

The invention relates to a bearing module (1) used for an OHC air valve transmission device of a single cylinder motorcycle internal combustion engine. The bearing module (1) is provided with two vertical bearing walls (2) separated from each other, wherein each bearing wall (2) is provided with a main drilling hole (5) provided with a cam shaft and two auxiliary drilling holes (7, 8) with two air valve operation shafts (9, 10), wherein the bearing module (1) form an enclosed box shape. The bearing walls (2) are connected through a cross wall (12) at a end part end side (11) in a separate manner and are enclosed through separately spliced boards (14) at the opposite end part end side (13), wherein support pins (15) used for connecting the bearing modules (1) to the cylinder head protrude from the lower end of the bearing walls (2) separately and the bearing walls (2) and the board (14) are made of steel boards by using punching bending technology.

Description

technical field [0001] The invention relates to a carrier module for an OHC valve train of an internal combustion engine, which has two upright and spaced-apart carrier walls, which can be connected at their upper end to a cover and at their lower end to a Cylinder head connection, wherein the carrier wall has a main bore either for or with the camshaft and a secondary bore either for or with at least one valve lever shaft . Background technique [0002] Such a carrier module is used, for example, in single-cylinder motorcycle engines with two-valve technology (2V-Technik) and consists of aluminum castings (see valve train fitted in Honda CG150 Titan (Brazil), Honda engine, KRM / KVS) . The lever (rocker arm) for operating the two gas exchange valves is mounted on a separate valve operating lever shaft. Such a support module is relatively solid and requires no construction space. The functional surfaces of the carrier modules, such as bores for one or more camshafts and va...
