company news about What is the tubeless unequal thickness weldless integral steel wheel?

The utility model relates to an integral steel wheel without inner tube of unequal thickness and without welding seam, which comprises a rim and a spoke. The Rim and the spoke are integrally formed and formed by spinning steel plates, the spoke surface of the spoke is one of a flat cone surface, a convex cone surface or a concave cone surface. The invention adopts the integral spinning forming technology of the steel plate, omits the previous manufacturing and reassembling welding procedures of the rims and spoke of the split-type wheel respectively, and avoids the use of the sealing ring, the utility model not only reduces the manufacturing process, but also thoroughly eliminates the inflation leakage problem of the traditional wheel. The invention solves the problem that the strength of the aluminum wheel material is lower than that of the steel wheel, and realizes the manufacture of the finished wheel with unequal thickness under the condition of equal strength, the utility model improves the bearing capacity and achieves the goal of lightweight of the wheels.
