AI Technical Summary
Technical Problem
While pursuing lightweight, existing wheel hubs are difficult to ensure the tread strength, especially in new energy vehicles, where tire noise causes more prominent noise problems.
Method used
Foam aluminum material is used as the tread surface of the wheel hub, and an annular cavity is formed between the rim bending and the spokes, combined with an annular plate and a Helmholtz muffler to achieve lightweight and sound attenuation effects.
Benefits of technology
Effectively reduce the weight of the wheels, and at the same time improve the strength of the tire, with a good sound absorption effect, and it is suitable for new energy vehicles.

Abstract
An annular sleeve A is coaxially fixed to the end, away from a spoke, of the outer side wall of a rim, a tire mounting face of the rim is formed on the outer side wall of the annular sleeve A, the annular sleeve A is made of foamed aluminum, and the end, facing the spoke, of the outer side wall of the rim is bent to form the tire mounting face to be fixed to the spoke. The spoke faces the end face of the rim, an annular cylinder is coaxially arranged at the position corresponding to the inner side wall of the rim, the end, away from the spoke, of the outer side wall of the annular cylinder is fixed to the outer side wall of the rim, and an annular cavity coaxial with the rim is formed among the tire mounting face of the connecting end of the rim and the spoke, the spoke and the annular cylinder. According to the structure, according to the foamed aluminum silencing hub, the tire mounting surface at one axial end of the hub is made of the foamed aluminum material, and the annular cavity is formed between the tire mounting surface at the other axial end of the hub and the spoke after the tire mounting surface is bent through the rim, so that the weight of the hub can be effectively reduced, and the rim and the spoke can be welded and fixed conveniently.
