DIRECT DRIVE BRAKING SYSTEM INCLUDING AN INTEGRATED PACKAGE BEARING

摘要

A wheel bearing hub and disc brake rotor assembly for use on vehicles includes a rotor (14) and a wheel mount (24), formed as a package bearing, fastened to the rotor with a connection assembly that promotes in plane torque transfer. The rotor has a flange form as a series of spaced tabs (20), and the wheel bearing hub (14) has a shoulder with complementary spaced tabs (34). The rotor is connected to the bearing hub by clamping a bridge (42) that spans the shoulder tabs over the rotor tabs. A spring clip (50) can be use with the bridge to accommodate thermal expansion of the rotor and eliminate rattling. Torque is transferred from the brake rotor to the bearing hub in a common plane to prevent twisting. In one embodiment, the bearing hub shoulder tabs may be formed by milling or machining slots. In another embodiment, the bearing hub shoulder tabs may be formed by fine-blanking or stamping slots.
