Abstract: A wedge lock wheel assembly for mounting a tire rim in which the assembly includes a hub rigidly attached to the rim having a chamber with a centerline substantially perpendicular to the disk, a plurality of stops and a plurality of pairs of paired ramps with a known hardness having complex angles relative to the disks, a plurality of sets of paired wedges positioned within the chamber capable of relative motion therebetween and having an aperture passing through each of said pairs, a generally flat and bottom surface, a slope top surface and a hardness greater than the hardness of the ramps, a plurality of restraining members for limiting the motion between sets of said wedge pairs, an axle having horizontal contact surfaces with a hardness greater than the hardness of the wedges and a plurality of connecting elements passing through said wedge apertures for establishing contact between said ramps and said slope surfaces and between said bottom surfaces and said contact surfaces.

Abstract: A clamping assembly mounting a cylindrically bored hub onto a shaft in which a double-taper ring and two self-locking tapered clamping sleeves are clamped together by means of axially oriented clamping bolts, the double-taper ring having a peripheral collar between the clamping sleeves for engagement by the clamping bolt, when the sleeves are to be unclamped from the double-taper ring.

Abstract: A taper adapter sleeve for mounting an element with a bore, for example a roller bearing, on an axle journal or the like, characterized in that it comprises a portion, the inner and/or outer surface of which is provided about its circumference with axially directed grooves and ridges, and that the crests of said ridges define a circumscribed or inscribed cone or cylinder.
