Abstract

L'invention se rapporte à un frein à tambour (26) comprenant un plateau (27) équipé d'un cylindre de roue (31) et d'une butée (32) portant un premier et un second segment (28, 29) ayant chacun une âme (38) en tôle comprenant une première extrémité (41) en appui sur le cylindre de roue (31) et une seconde extrémité (42) en appui sur la butée (32), ces âmes (38) s'étendant selon un même plan médian (PM), le premier segment (28) étant équipé d'un levier (46) de frein de parc et comprenant une première extrémité (49) liée en rotation à la première extrémité (41), une biellette (43) ayant une extrémité (45) en appui sur le second segment (29). Le levier (46) comporte deux flancs s'étendant de part et d'autre de l'âme (38), et comportant chacun une portion de poussée (60, 61) par laquelle il est en appui sur une première extrémité (44) de la biellette (43).The invention relates to a drum brake (26) comprising a plate (27) equipped with a wheel cylinder (31) and a stop (32) carrying a first and a second segment (28, 29) having each a web (38) in sheet metal comprising a first end (41) resting on the wheel cylinder (31) and a second end (42) resting on the stop (32), these webs (38) extending along the same median plane (PM), the first segment (28) being equipped with a parking brake lever (46) and comprising a first end (49) connected in rotation to the first end (41), a link (43) ) having one end (45) resting on the second segment (29). The lever (46) comprises two flanks extending on either side of the core (38), and each comprising a thrust portion (60, 61) by which it bears on a first end (44) of the connecting rod (43).
