  • Patent number: 6626579
    Abstract: This invention relates to an anti-corrosion member adapted for use in a vehicle wheel end assembly vehicle wheel end assembly. The vehicle wheel end assembly includes a bearing unit formed from steel and including a pilot surface and a steering knuckle formed from aluminum and having a portion supported on the pilot surface of the bearing unit. The assembly further includes an anti-corrosion member disposed on the pilot surface of the bearing unit so as to be interposed between the bearing unit and the portion of the steering knuckle when assembled so as to prevent direct contact therebetween whereby galvanic corrosion between the steel bearing unit and the aluminum steering knuckle is prevented. The anti-corrosion member can be formed from plastic or formed from metal and coated with an anti-corrosive material.

  • Patent number: 6538427
    Abstract: A wheel speed sensor and bearing assembly for use in a wheel end assembly of a vehicle. The assembly includes an outer race, an inner race, a bearing unit, a spindle, a wheel speed sensor and a tone wheel. The outer race includes an opened inboard end, an opened outboard end, and at least one bearing seat. The inner race includes at least one bearing seat. The bearing unit is disposed between the bearing seats of the outer race and inner race. The spindle is adapted to be secured to a fixed component of the vehicle and includes an inboard end, an outboard end, and an opening formed therethrough. The wheel speed sensor is operatively connected to the spindle adjacent the outboard end thereof. The wheel speed sensor includes an outer magnet surface. The tone wheel is operatively secured to the outer race adjacent the opened outboard end thereof. The tone wheel includes an inner surface which is positioned in a spaced apart relationship relative to the outer magnet surface of the wheel speed sensor.

  • Patent number: 5957250
    Abstract: A brake shoe assembly is formed by precision stamping a net shaped web blank having a series of tabs projecting outward therefrom and stamping a corresponding table member provided with tab receiving apertures and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily prior to the cooperating tabs and apertures being permanently joined together using a hot staking process without any portion thereof extending substantially beyond the outer semi-cylindrical surface of the table.

  • Patent number: 5839550
    Abstract: A brake shoe assembly is formed by precision stamping a net shaped web blank out of steel forming a series of tabs projecting outward therefrom, stamping a corresponding table member provided with tab receiving apertures, and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily together. The cooperating tabs and projections are then permanently joined together using a hot staking process which quickly heats, radially deforms and self quenches the tab to metallurgically strength the joint.
