CORE ASSEMBLY FOR A BRAKE DISK

摘要

A core assembly (4) for a brake disc (8) of ceramic material provided with two rotor plates (12) having a predetermined axis (X), the said plates (12) having radially an inner edge (13) and an outer edge (14), having a predetermined thickness (S) and being separated from each other by a central layer (15) with ventilation ducts (16). The core assembly (4) can be inserted into a mould and comprises at least one core (20) provided with a core body (24) designed to produce a ventilation duct (16) which extends between the inner edge (13) and the outer edge (14). The at least one core body (24) comprises at least one protuberance (28) which projects from the said core body (24) and is designed to produce in a plate (12) a cavity (32) which is directed substantially parallel to the predetermined axis (X) of the plate (12).
