Abstract: An improved vehicle wheel hub mounting system includes a wheel hub, an axle spindle, a bearing assembly, and a threaded fastener. The wheel hub defines an axis and including a generally axially extending body having a bore formed therethrough. The bore of the wheel hub includes an internal splined portion and an inner annular wheel hub surface spaced apart from the internal splined portion. The inner annular wheel hub surface defines a predetermined wheel hub inner diameter. The axle spindle is connected to the wheel hub for rotation therewith and includes a generally axially extending body having an external splined portion and an outer annular axle spindle surface spaced apart from the external splined portion. The external splined portion of the axle spindle matingly receives the internal splined portion of the wheel hub to connect the axle spindle to the wheel hub for rotation therewith.

Abstract: This invention relates to a vehicle wheel hub and brake rotor including a wheel hub portion formed from a first material and a brake rotor portion formed from a second material and joined to the wheel hub flange during an in situ casting process. The method for producing the vehicle wheel hub and brake rotor of the present invention includes the steps of (a) providing wheel hub portion formed from a first material and including a radially outwardly extending wheel hub flange; (b) placing the wheel hub portion in a mold; and (c) casting a brake rotor portion formed from a second material in situ therewith, the brake rotor portion including a flange which is operatively joined to the wheel hub flange during the in situ casting process to thereby join the wheel hub portion to the brake rotor portion.

Abstract: An anchor bracket and brake shoe assembly adapted for use in a disc brake assembly includes an anchor bracket and a pair of brake shoes supported thereon. The anchor bracket includes an pair of axially and outwardly extending angled arms. The arms include a pair of inboard ends and a pair of outboard ends, at least one of the inboard ends and the outboard ends of the arms being interconnected by a tie bar. Each of the arms includes one of a male end and a female end, the one of the male end and the female end being located along a common arc of the anchor bracket and brake shoe assembly. Each of the brake shoes is generally arcuate in shape and includes a backing plate and a friction pad. Each of said backing plates including opposed ends, the opposed ends being the other one of the male end and the female end and configured so as to generally match the profile of the one of the male end and the female end of the arms so as to slidably support the brake shoes on the arms of the anchor bracket.

Abstract: This invention relates to an improved structure for a wheel cylinder for use in a drum brake assembly having a pair of brake shoes which are adapted to be urged into frictional engagement with a brake drum. The wheel cylinder includes a pair of opposed piston assemblies each having a piston body formed from a plastic material and a piston insert formed from metal. In accordance with one embodiment of this invention, the piston insert is molded in situ with the piston body and the piston insert includes a radially outwardly extending first flange and a radially outwardly extending second flange. The first flange defines a first flange outer diameter, and the second flange defines a second flange outer diameter which is less than the first flange outer diameter.

Abstract: An improved vehicle wheel hub mounting system includes a wheel hub, an axle spindle, a bearing assembly, and a threaded fastener. The wheel hub defines an axis and including a generally axially extending body having bore s formed therethrough. The bore of the wheel hub includes an internal splined portion and an inner annular wheel hub surface spaced apart from the internal splined portion. The inner annular wheel hub surface defines a predetermined wheel hub inner diameter. The axle spindle is connected to the wheel hub for rotation therewith and includes a generally axially extending body having an external splined portion and an outer annular axle spindle surface spaced apart from the external splined portion. The external splined portion of the axle spindle matingly receives the internal splined portion of the wheel hub to connect the axle spindle to the wheel hub for rotation therewith.
