The invention provides a split wheel. The split wheel comprises a turntable part 1, a rim part 2 and a metal fastening ring 3, wherein the turntable part 1 is made of an aluminum alloy; the metal fastening ring 3 is made from 65Mn steel; the rim part 2 is made from a carbon fiber composite material; the rim part 2 and the metal fastening ring 3 are fixed to the turntable part 1 through a bolt or a rivet together. The technical scheme provided by the invention has the following advantages that the contact area of the place where the rivet or the nut and a composite material rim are connected is effectively increased by the metal fastening ring, fastening force is dispersed and is more uniform; under the action of the metal fastening ring, the pre-tightening torque can be increased. The problems that the tightening torque is reduced and the wheel fails are effectively solved.
