The invention proposes a unipartite support module (1), produced from a sheet steel blank by punching and bending techniques, for an OHC valve drive of an internal combustion engine, having two upright supporting walls (2) which are spaced apart from one another and which are connectable, at the top ends (3) thereof, to a cylinder head cover and, at the bottom ends (4) thereof, to a cylinder head and which have in each case at least one main and secondary bore (5, 6) for the mounting of a camshaft and valve actuating lever shaft (7, 8, 9) between said supporting walls, wherein each supporting wall (2) is composed of two supporting plates (10, 11) which are integrally connected either at the top or bottom ends (3, 4) by a transverse wall (12), and wherein opposite inner supporting plates (11) are connected by a transverse plate (13) which runs on a side opposite the transverse walls (12). |
