Title: BRAKE DRUM AND METHOD FOR PRODUCING SUCH A BRAKE DRUM
Abstract:
The invention relates to a brake drum for a vehicle comprising a friction ring (10), which has grooves (16, 18) on the radial outer surface (14) of the friction ring along the circumference and a coating (40) formed on the radial outer surface (14), and a drum body (12) which is cast onto the radial outer surface of the friction ring (10) such that the grooves (16, 18) are filled with the material of the drum body (12), wherein on the friction ring (10) a first axial segment (20) is formed, in which the grooves (16) are introduced with an inclination relative to the closest first axial end (24) of the friction ring (10) and a second axial segment (22) is formed, in which the grooves (18) are introduced with an inclination in the opposite direction to that of the first segment (20), wherein the grooves (16, 18) have undercuts (26, 32) when viewed in the radial direction.
