AI Technical Summary

Technical Problem

The existing steel and aluminum wheels need to be embedded in steel sheets when casting aluminum spokes, resulting in complex casting process and high cost, low fatigue test life in the weld area and low product quality.

Method used

A steel and aluminum wheel is designed, by providing a mounting groove at the connecting portion of the spoke, the connecting ring is welded to the rim of the rim, and through the interference fit of the connecting ring with the mounting groove, the rim and the spoke are fixed to avoid separation and relative rotation.

Benefits of technology

The stable connection between the rims and spokes of different materials is achieved, the quality and service life of the wheels are improved, the production process is simplified, and the production difficulty and energy consumption are reduced.

Abstract

The invention relates to the technical field of automobile parts, in particular to a steel-aluminum wheel and a machining process thereof, and the steel-aluminum wheel comprises a rim and a spoke; the spoke is provided with a connecting part, a mounting groove is formed in the connecting part, a connecting ring is welded to the rim of the rim, and the connecting ring is mounted in the mounting groove; the rim and the end, deviating from the mounting groove, of the connecting part are connected in a spin riveting mode in the circumferential direction of the wheel. According to the steel-aluminum wheel, connecting pieces do not need to be embedded in the spokes, so that the connecting structure of the rim and the spokes is more stable, the effect of improving the product quality is achieved, the performance of the wheel can be effectively improved, and the service life of the wheel is prolonged. According to the machining process of the steel-aluminum wheel, the whole production and machining process of the steel-aluminum wheel is simpler, so that the production efficiency can be effectively improved, and the quality of a produced product is guaranteed.
