The technical field is as follows: the invention belongs to the technical field of commercial automobile tubeless wheels, and particularly relates to a commercial wheel with a light-weight and high-performance steel-aluminum combined structure.

Background art: at present, the commercial automobile has two types of tubeless wheel structures, one is a wheel with a steel structure, and the other is a wheel with an aluminum alloy structure. The steel structure wheel is formed by welding a steel spoke and a steel rim, and the structure has the advantages that the structural rigidity of the rim is high, and the bearing capacity is superior to that of an aluminum alloy wheel. Compared with a pure steel wheel, the aluminum alloy wheel has light weight, more attractive spoke appearance and good heat dispersion performance, but the rim rigidity and the bearing capacity are lower. With the further promotion of the national automobile emission policy, the low emission requirement on the light weight of the automobile is higher and higher, and the contradiction between the light weight and the bearing capacity of the automobile wheel is more and more prominent, so that a novel steel-aluminum structure wheel which can keep the original bearing capacity and is lighter in weight needs to be developed.

The invention content is as follows: the invention aims to provide a commercial vehicle steel-aluminum combined structure wheel which is light in weight, high in performance, strong in bearing capacity and attractive in appearance.

The technical scheme of the invention is as follows: the utility model provides a commercial wheel of lightweight, high performance steel-aluminum integrated configuration, inserts in steel structure rim, aluminum alloy system structure spoke and the steel structure, characterized by: the aluminum alloy structure spoke and the steel structure inner insert are connected into a whole through a casting process, the steel structure inner insert and the steel structure rim are welded and combined in a universal welding mode of the steel wheel, and the steel structure rim, the aluminum alloy structure spoke and the steel structure inner insert are firmly combined together through the combination mode to form a new steel-aluminum structure wheel.

A plurality of round and special-shaped through holes or a plurality of grooves are processed on the connecting surface of the steel structure inner insert and the aluminum alloy structure spoke to enhance the casting connecting strength with the aluminum alloy structure spoke.

By adopting the technical scheme, the rigidity and the bearing capacity of the wheel can be guaranteed by the steel structure rim, the heat dissipation performance and the attractiveness of the wheel are guaranteed by the aluminum alloy structure spoke, and the quality of the aluminum alloy structure spoke is far lighter than that of the steel structure spoke, so that a good light-weight effect can be obtained. The inner insert and the aluminum alloy structure spoke are connected into a whole through a casting process, and a plurality of round holes and special-shaped holes or a plurality of grooves are processed at the connecting part of the inner insert, so that the aluminum alloy spoke part and the steel insert part which are formed by casting are locally hooked with each other, and the connecting strength and the safety performance between the aluminum alloy spoke part and the steel insert part are ensured. The welding structure design of the inner insert and the rim also solves the problem that the aluminum alloy spoke and the steel rim can not be well welded, and the welding strength between the spoke and the rim is ensured. Therefore, the wheel with the steel-aluminum structure has the advantages of light weight, high performance, strong bearing capacity, quick heat dissipation, safety, reliability and attractive appearance.
