<p>The invention proposes a modular-type, composite crossbar-less rocker arm (1) of a valve train of an internal combustion engine, comprising two separate, substantially upright side walls (2, 3) made out of thin-walled sheet steel and comprising, on a centre-proximate section (4), bores (5) through which said side walls (2, 3) are retained laterally spaced from each other on a separate tube member (6) which serves to mount the rocker arm (1) on a rocker arm axle, said side walls (2, 3) being bridged on one end (7) by an axle (8) comprising a cam contacting roller (9) and, in direction towards a further end (10), following the tube member (6), said side walls (2, 3) extend towards each other from one or from both sides and end in semi shell-like outward bends (11, 12), the front ends (13, 14) of which outward bends adjoin each other, wherein a closing cup (17, 18) that additionally fixes the side walls (2, 3) extends over covering sides (15, 16) of the outward bends (11, 12), and these outward bends (11, 12) receive a clearance adjusting screw (19).</p> |
