    • The apparatus of the present invention provides a brake rotor assembly. The brake rotor assembly includes a generally annular rotor having a frictional surface and a radially inner rotor flange defining a plurality of rotor teeth. The brake rotor assembly also includes a hub section integrally formed onto the rotor. The hub section has a peripheral hub flange configured to engage the plurality of rotor teeth and thereby prevent rotation of the hub section relative to the rotor. The rotor is preferably composed of a first material such as steel or cast iron, and the hub section is preferably composed of a second material such as aluminum or magnesium that is lighter by volume than the first material. Accordingly, the overall weight of the rotor assembly is less than that of a comparable rotor assembly composed entirely of steel or cast iron.
    • 本发明的装置提供一种制动转子组件。 制动转子组件包括具有摩擦表面的大致环形的转子和限定多个转子齿的径向内转子凸缘。 制动转子组件还包括一体地形成在转子上的毂部。 毂部分具有外围轮毂凸缘,其被配置为接合多个转子齿,从而防止轮毂部分相对于转子旋转。 转子优选由诸如钢或铸铁的第一材料构成,并且毂部优选地由体积比第一材料轻的第二材料例如铝或镁构成。 因此,转子组件的总体重量小于完全由钢或铸铁组成的类似转子组件的重量。
