Modular steel wheels

Abstract

This utility model discloses a modular steel wheel hub, including a rim and spoke module. The rim and spoke module includes an integrally formed rim and several evenly distributed spokes located on the inner sidewall of the rim. It also includes a mounting module, which includes: a hub disc, which is a cylindrical cup-shaped body with an inward opening; a wheel disc, which includes a first wheel disc and a second wheel disc, the first wheel disc and the second wheel disc having several opposing slots, two opposing slots forming a receiving groove, one end of the spokes extending into the receiving groove and fitting against the sidewall of the receiving groove and being clamped and fixed; a hub shaft, which has an annular connecting plate on its side, the connecting plate extending from the opening and abutting against the bottom of the hub disc, and the connecting plate, the bottom of the hub disc, the second wheel disc and the first wheel disc having several sets of opposing mounting holes; and fasteners, which pass through the connecting plate, the bottom of the hub disc, the second wheel disc and the first wheel disc to fix the four together. This application sets the wheel hub as a modular structure, in particular dividing the existing wheel hub disc into a separate structure of the wheel hub disc and two disc bodies. Each part is manufactured separately during production, and then the spokes are welded to the rim. After welding, the inner ends of the spokes are clamped and fixed by the two disc bodies and then fixed to the wheel hub disc by fasteners. This installation structure is more stable and avoids the problem of short weld lines and easy desoldering when directly welding.
