In a cylindrical surface of a gutter band of a wheel rim and a cylindrical surface of a spider hub opposed to one another, a conical surface is formed on one side of the cylindrical surface of the gutter band or that of the spider hub, or on both respectively. A wedge member is inserted between the formed conical surface and the cylindrical surface, or the formed conical surfaces, thereby forming a spider hub and wheel rim assembly.

A wheel rim and spider hub assembly of the flange-removable type for multiple-piece wheel rims, said assembly comprising: a. a spider hub having an axial line, a front face, an outer circumference including an outer cylindrical surface extending parallel to the axial line and an inner conical surface having an inclined angle, and a plurality of clamp bolts extending outwardly from the front face; b. a wheel rim positioned co-axially around the spider hub and having a cylindrical rim base comprised of: (1) a cylindrical, cantilevered gutter band extending parallel to the axial line and having an inner conical surface defined along the surface of the gutter band next to the spider hub and matingly engaging the inner conical surface of the spider hub to thereby support the gutter band, an outer conical surface defined along a surface of the gutter band next to the spider hub and near the front face thereof and including an inclined angle, and a gutter circumferentially defined along the surface thereof remote from the spider hub; (2) an annular split locking ring having an upper conical surface including an inclined angle and being adapted to engage the gutter of the gutter band; (3) an annular bead seat band having a conical outer edge which matingly engages the upper conical surface of the split locking ring, the band extending parallel to the axial line and being overlappingly positioned parallel to and outwardly from the gutter band on the side thereof remote from the spider hub; and (4) an annular side flange outwardly and abuttingly positioned next to the bead seat band, wherein the split locking ring holds an annular body formed by the abutted side flange and the bead seat band and engages the annular body along the conical outer edge of the bead seat band; c. a plurality of L-shaped clamp pieces, each clamp piece having a wedge member inserted between the outer conical surface of the gutter band of the wheel rim and an outer cylindrical surface of the outer circumference of the spider hub to provide support for the cantilevered gutter band, each wedge member including a conical surface which matingly engages the outer conical surface of the gutter band and an inner cylindrical surface which abuts the outer cylindrical surface of the outer circumference of the spider hub, each clamp piece having a hole for receiving one of the plurality of clamp bolts, and each clamp piece being clamped to one of the plurality of clamp bolts by a clamping means to thereby join the spider hub and the wheel rim into an assembly.
