Further, the axial cross-sectional shape of the boss portion is rectangular, and the through-hole is arranged on a radial side face of the boss portion.
Further, the radial edge of the inboard flange extends axially toward the vehicle side and the radial edge of the outboard flange extends axially away from the vehicle side.
Further, the axial length of the groove bottom is greater than the axial length of the outboard bead seat and the axial length of the inboard bead seat.
Further, the inboard bead seat and the outboard bead seat are of equal axial length.
Further, the rim body is formed by adopting an integral casting, thinning and spinning process.
Further, the integral casting, thinning and spinning process is to adopt a low-temperature rapid solidification (pouring of molten aluminum below 650 ℃) technology to produce a rim casting and spinning blank; then the blank is thinned and formed by spinning through a hot spinning up-down spinning technology; and finally, machining the spun workpiece into a finished rim product.
Further, the hot spinning up-down technology is to preheat a casting blank of the rim at 350-450 ℃ and then hot spin the casting blank, wherein the rotating speed of a spinning main shaft is 400-.
The utility model discloses an innovation point and beneficial effect are:
(1) the utility model provides an aluminum alloy rim adopts whole casting attenuate spinning technology shaping, avoids adopting welding process to lead to the mechanical properties reduction of weld part and easily dismantles, maintains.
(2) The utility model provides a rim body of aluminum alloy rim adopts the combination of casting and spinning technique, promotes the performance of material to alleviate the quality of rim.
