Abstract

PURPOSE: To achieve a reduction of the weight of wheels while retaining sufficient strength without the use of bolts, rivets and such like by uniting a light alloy rim and spokes by means of shrinkage or expansion fit.
CONSTITUTION: A light alloy material extruded previously to form flange 1, bead 2 and drop 3 is rolled and cut to the required length determined on the basis of the circumferential length along the bead 2. The cut ends are joined together by flash butt welding to form a ring-shaped rim R. On the other hand a connecting piece 5 of a light alloy spoke S is formed with a proper fitting allowance to the inner diameter of drop 3 of rim R. The rim R is heated for shrinkage fitting or the spoke S is cooled for expansion fitting to join them together.
