  • Patent number: 9038271
    Abstract: An automotive disk brake assembly installed in an automobile having a wheel. The assembly includes a floating caliper supporting inner and outer brake pads and a brake rotor having a disk, a hat, wherein the hat is bolted to the wheel. A hydraulic cylinder pushes the inner brake pads into the disk surface, thereby causing the floating caliper to move so as to bring the outer brake pad into contact with the disk surfaces. Finally, the rotor is made of a material having a thickness and a coefficient of thermal expansion and conductivity, such that a complete 100 kilometer per hour, 0.9 gross vehicle weight braking causes the disk to expand in thickness by at least 0.10 mm and to cool to shrink in thickness, from its expanded thickness, by at least 0.05 mm within 60 seconds of cessation of braking, in an ambient temperature of less than 30° C.

  • Patent number: 6829825
    Abstract: A process for manufacturing a corner assembly for a vehicle. A wheel hub is partially machined to define a journal section and a radial mounting flange on an out-board surface of the hub. Bolts are pressed into axial openings in the mounting flange and the hub further machining to produce a concentric wheel pilot, rotor pilot and bearing journal surfaces that are perpendicular to radial faces on an out-board surface of the mounting flange. The hub is pressed into a bearing retained of a support member and a rotor is placed on the rotor pilot surface such that the bolts extend through openings located on the inner peripheral surface of the rotor. The hub is rotated to gage lateral deflection with respect to its axis. If the deflection is less than 0.06 mm, the wheel hub and rotor are accepted for installation on a vehicle and rejected if greater that 0.06 mm.

  • Patent number: 6374493
    Abstract: A two-piece tire rim is prepared from a molded, one-piece wheel casting which is generally cup-shaped in configuration. The casting, which is open at one end and closed at its opposite end, has an inner annular recess formed coaxially in the inner surface of its closed end, and has formed coaxially in its outer peripheral surface an external annular recess radially spaced from, and in axial registry with an internal annular recess. The casting is separated into two separate sections by cutting through the casting in a circular path extending from the external annular recess to the internal annular recess, thereby producing a generally annular shaped inner rim section, and a generally disc-shaped outer rim section. The two rim sections are then machined to final form, and are secured together to form the desired two-piece tire rim.
