Claim:
A bimetallic brake rotor, comprising: a rotor body comprising a disc component having first and second outer sides, said rotor body being composed of a first material; an annular first cheek insert having an inner side and an outer side, said first cheek insert being composed of a second material; an annular second cheek insert having an inner side and an outer side, said second cheek insert being composed of said second material; a first tooth and slot sequence of sequentially alternating teeth and slots disposed, respectively, on the inside surface of each of said first and second cheek inserts; a second tooth and slot sequence of sequentially alternating teeth and slots, reciprocal to said first tooth and slot sequence, disposed, respectively, on each of said first and second outer sides of said disc component; and a pair of insert recesses, one insert recess, respectively, being disposed at each of said first and second outer sides of said disc component, each insert recess of said pair of insert recesses being defined by an inner peripheral wall, an outer peripheral wall and a floor extending between said inner and outer peripheral walls, wherein the second tooth and slot sequence of each of the first and second outer sides is disposed at said floor of each said insert recess; wherein the first tooth and slot sequence of said first cheek insert is meshed with the second tooth and slot sequence of said first outer surface of said disc component such that a radial edge press-fit interface is disposed at each adjoining tooth and slot, wherein the press-fit holds said first cheek insert seated in its respective insert recess; and wherein the first tooth and slot sequence of said second cheek insert is meshed with the second tooth and slot sequence of said second outer surface of said disc component such that a radial edge press-fit interface is disposed at each adjoining tooth and slot, said radial edge interface being oriented in orthogonal relation to said floor of each said insert recess, wherein the press-fit holds said second insert seated in its respective insert recess.
