<p>The invention concerns a guide rail comprising above the tie pad of its core (3) a railhead (4) formed by two cambered convex flanks (5) and (6) whereof the top parts form upper ramps (13) and (14) serving as running track for inclined guide rollers and assembled by a linking zone (8). Said upper ramps are extended downwards by curved surfaces (12) and (13) followed by lower ramps (15) and (16). The guide rail comprises in certain places engaging-releasing zones formed by opposite slots (21) and (22) in the form of an indentation towards the core (3) central portion for example a linear recess of the curve of each flank so as to allow a guide roller shoulder or stub to pass without materially spacing or modifying the inclination. Said invention is of interest to rail producers and manufacturers of rail-guided road vehicles.</p> |
