DETAILED DESCRIPTION

First Embodiment

(7) Provided in the present embodiment is a motor vehicle aluminum alloy hub with an inner flange 26 having weight reduction sockets 21. The hub includes a wheel disc and a rim 11, and the wheel disc includes a flange plate 12, a flange plate periphery portion and spokes 13. The inner flange 26 of the hub includes weight reduction sockets 21, the strip weight reduction socket unit on the inner flange 26 is as shown in FIG. 2, the weight reduction sockets 21 have a width L of 18 mm, a height H of 34 mm, a draft angle of 7, a depth H1 of 3 mm and an internal excessive fillet size of R2 mm, and 36 weight reduction sockets are arranged, on average, on the circumference. In the tests, the weight of the hub is 11.29 kg without weight reduction sockets 21 and is reduced by 0.2 kg with weight reduction sockets 21, and the weight of the hub is reduced by about 1.8%.

Second Embodiment

(8) Various properties of the motor vehicle hub of first embodiment were tested. The strengths and fatigues, including 13-degree impact strength, 90-degree impact strength, radial impact, radial fatigue, bending fatigue and the like, of the above wheel were tested in the test center of Dicastal. The tests show that the hub meets American Wheel Standards of SAE J175 and SAE J328-2005, namely meet the performance requirements for 13-degree impact strength, radial fatigue and bending fatigue, and can also meet the requirements of GB/T 5334-2005 and GB/T 15704-1995 for wheel strengths and fatigues.
