Abstract:
A rocker arm (1) made of thin-walled sheet steel which rocker arm is intended for a suspended arrangement together with other like rocker arms under a girder-like carrier (2) of a valve train of an internal combustion engine, the rocker arm having an inverted U-shaped profile, a support (7) for a gas exchange valve is formed on one end (6) of an underside (5) of a crossbar (4) of the rocker arm, an upper side (9) of the crossbar (4) is stamped in the region of the support (7) by a stamping and extrusion molding method toward the underside (5), so that an M-like cross-section with a longitudinal channel (10) formed on the upper side (9) is obtained and at its other end (11), the rocker arm (1) has a fork-shaped, open configuration and merges into a region (12) which is angularly bent towards the underside (5) and on which a roller (13) forming a cam contacting surface is arranged, said rocker arm (1) of this type possesses, among other things, an excellent stiffness, is simple to manufacture and has a small design height requirement.
