Abstract

La présente invention concerne un tambour de frein pour freins à mâchoires intérieures avec une paroi limitée par un pourtour cylindrique intérieur et un pourtour extérieur du tambour de frein, cette paroi étant garnie de moyens propres à atténuer les bruits de freinage. Selon l'invention, en plusieurs endroits 14, 15, 16, 17 et 18 du pourtour extérieur 12, l'épaisseur de la paroi 13 s'étendant sur une largeur principalement axiale du pourtour extérieur dévie légèrement de la symétrie cylindrique du pourtour intérieur 11 du tambour de frein 10, en présentant une faible augmentation de l'épaisseur normale et en passant à une épaisseur croissant constamment pour diminuer à nouveau sur le pourtour extérieur par rapport au diamètre du tambour de frein.The present invention relates to a brake drum for internal shoe brakes with a wall limited by an internal cylindrical periphery and an external periphery of the brake drum, this wall being fitted with means suitable for attenuating braking noise. According to the invention, in several places 14, 15, 16, 17 and 18 of the outer rim 12, the thickness of the wall 13 extending over a mainly axial width of the outer rim deviates slightly from the cylindrical symmetry of the inner rim 11 of the brake drum 10, showing a small increase in the normal thickness and passing to a constantly increasing thickness to decrease again around the outer periphery with respect to the diameter of the brake drum.
