Abstract (en)
[origin: WO2007082622A1] The invention relates to a rocker arm (1) consisting of thin-walled sheet steel. The arm is designed to be used in a suspended assembly comprising additional rocker arms beneath a bar-type support (2) of a valve train in an internal combustion engine and has an inverted U-shaped profile. The underside (5) of a transverse section (4) is equipped at one end (6) with a structure (7) for a gas exchange valve. The upper face (9) of the transverse section (4) is pushed downwards in the vicinity of the structure (7) in relation to the underside (5) in a stamping and extrusion method, to produce an M-shaped cross-section with a longitudinal channel (10) on the upper face (9). The other end (11) of the rocker arm (1) is forked and open, forming a region (12) that is bent at an angle towards the underside (5). A roller that acts as a cam thrust surface is attached (13) to said region. A rocker arm (1) of this type has excellent rigidity, can be simply produced and requires little headroom.
