The invention relates to the technical field of hub installation, in particular to a three-piece type aluminum alloy forged hub which comprises a rim front piece, a rim rear piece and a top arranged on the rim front piece, a first connecting ring is fixedly connected to the inner wall of the rim front piece, a first positioning groove is formed in the surface of the rim front piece, a first groove is formed in the inner wall of the rim front piece, and a second positioning groove is formed in the inner wall of the rim rear piece. A second connecting ring is arranged at the top of the first connecting ring, a third connecting ring is fixedly connected to the inner wall of the rim rear piece, a plurality of first threaded grooves are formed in the surface of the first connecting ring in the circumferential direction at equal intervals, and a plurality of second threaded grooves are formed in the surface of the second connecting ring in the circumferential direction at equal intervals; a plurality of third threaded grooves are formed in the surface of the third connecting ring in the circumferential direction at equal intervals, and the inner walls of the third threaded grooves are in threaded connection with bolts. Connection between the rim front piece and the rim rear piece is further enhanced through clamping between the first positioning rods and the annular positioning blocks, and therefore the stability of connection between the rim front piece and the rim rear piece is guaranteed.

    本发明涉及轮毂安装技术领域,具体为一种三片式铝合金锻造轮毂,包括轮辋前片,轮辋后片,设置于所述轮辋前片的顶部,所述轮辋前片内壁固定连接有第一连接环,所述轮辋前片表面开设有第一定位槽,所述轮辋前片内壁开设有第一凹槽,所述第一连接环顶部设有第二连接环,所述轮辋后片内壁固定连接有第三连接环,所述第一连接环表面周向等距开设有多个第一螺纹槽,所述第二连接环表面周向等距开设有多个第二螺纹槽,所述第三连接环表面周向等距开设有多个第三螺纹槽,多个所述第三螺纹槽内壁螺纹连接有螺栓。本发明通过第一定位杆与环形定位块之间的卡合进一步加强了轮辋前片与轮辋后片之间的连接,从而保证了轮辋前片与轮辋后片之间连接的稳定性。
