Abstract: A wheel end hub assembly for a motor vehicle incorporating mechanical retention features. The assembly accurately and positively orients the motor vehicle brake component, such as a disc brake rotor or brake drum with respect to its wheel hub. Accordingly, the machining operations for the brake component braking surfaces can be accurately based from a datum surface of the hub. The assembly incorporates a retention nut threaded onto the wheel mounting bolts which exerts a clamping force on the brake component and further establishes the relative positions of the hub and brake component. The retention nut features a generally conical surface which contacts a generally conical surface of the brake component to establish the radial and rotational relative position of these components.

Abstract: A composite brake disc and drum assembly for a motor vehicle having a rear disc brake system and a parking brake system. The assembly includes a body of a first material having a mounting web, a skirt and a flange. The skirt extends from the perimeter of the mounting web and cooperates therewith to define a brake drum. The skirt has an inside surface which defines a cylindrical braking friction surface for engagement with the parking brake shoe. The flange extends outward from the skirt and at least one annular plate is supported by the flange so as to extend in a plane generally perpendicular to the axis of rotation. The plate includes a surface defining an annular braking friction surface for engagement with the disc brake pads.

Abstract: A wheel hub assembly for a non-driven axle including a hub, a bearing retainer ring and a bearing. The bearing retainer ring is secured to the hub by engagement of the wheel mounting studs with the hub. A portion of the bearing retainer ring directly engages and positively provides an axial retention load on the bearing. The resulting structure is a compact and light weight wheel hub assembly having simplified, cost efficient construction.
