Research on a Connection Method of Steel-aluminum Composite Wheel Hub Based on Low Carbon Emission
The method of creative connection between steel rim and aluminum alloy cast spoke is introduced in this paper,which can not only reduce the carbon emission in rim manufacturing process,but also keep the diversified shape and beautiful properties of cast aluminum alloy spoke.The reliability test of the sample wheel shows that the reliability of the composite hub is qualified.Compared with traditional aluminum alloy wheels of the same size,carbon emissions are reduced by more than 52%,metal utilization data showed an increase of 14%,the overall time efficiency of full-sequence machining is increased by 39%,and there is potential for further weight reduction.At the same time,it has the advantages of the appearance diversity of aluminum wheels.
