Abstract: A wheel retention nut includes a body having a front face and a rear face. A central bore with internal threads extends through the body. A first outer perimeter of a first diameter is positioned adjacent to the front face. The first outer perimeter defines a polygon adapted to receive a wrench. A second outer perimeter of a second diameter, which is larger than the first diameter, is positioned adjacent to the rear face. The second outer perimeter is sized to retain an eccentrically rotating wheel.

Abstract: In the trucking industry, a wheel stud having a recess at either end to accommodate a sacrificial insert of metal higher in the electromotive series of metals than the metals of the wheel stud assembly, the lug and the components joined thereby and being of sufficient difference in color from the surrounding materials so as to be readily visible without disassembling the combination, and a method for its use.

Abstract: A bearing device for an axle including a hub wheel; a flange outwardly provided in an outer-periphery of the hub wheel in a radial direction; and bolts having serrations provided at their heads. The flange includes through holes formed therein in its circumferential direction such as to pass therethrough ill its axial direction, the bolts are attached into the through holes, respectively, in a state where their serrations bite the trough holes of the flange, and an annular groove for reducing a biting amount of the serrations of the bolt is formed in an inner peripheral surface of the through hole of the flange.

Abstract: A tension control arrangement including a plurality of cams disposed about an opening that accommodates a bolt to which a nut is intended to be secured. Each of the cams has a contoured outer surface, and each of the cams is rotatably supported such that the contoured outer surface operatively engages both the base and a contact member interposed between the cam and the nut. A lever assembly is operatively coupled to the cams, such that movement of the cams is substantially restricted to rotational motion from a first position in which the nut is engaged with the bolt and tightened by hand until it is seated against the contact member, to a second position in which the bolt is elongated to achieve a predetermined bolt tension.

Abstract: A method of forming a hole to a final specified dimension in a fiber reinforced wheel for a motor vehicle, and a fiber reinforced wheel with such a hole. Stud mounting holes, or a hub hole or a valve hole, are drilled through the wheel to an internal dimension larger than the final specified dimension, to sever and expose fiber ends in the wheel surrounding the hole. Thermoset resin with coupling and curing agents is applied to the hole internal surfaces by brushing or spraying, and is thereafter cured, and atomically and mechanically bonded to the internal hole surfaces with exposed fiber ends to form a thin smooth permanent protective layer on the hole internal surfaces defining the hole at final specified dimension. The hole may have frustoconical, spherical radius, and/or cylindrical portions.
