Multi-layer disk brake rotor

摘要

A disk or rotor for a disk brake system is formed of a number of stacked metal plates, normally with outside plates having a high resistance to abrasion and great strength and with inner plates formed of metal having good heat transfer characteristics and having inside and outside rims and generally radially directed slots between the rims, the inner plates being aligned such that the slots are held in registry, and all of the inner and outer plates are brazed together to form a unitary disk. Inside and outside diameters are then both trimmed to remove the rims and open the slots between fins formed when the inside and outside rims are cut away. One or more outside plates on one end of the stack are trimmed to a smaller diameter thus leaving a flange which is drilled to provide mounting holes for the disk. Modified forms of the disk include solid inside plates and inside plates with perforations or corrugations.
