    Abstract: The disclosure discloses a method of producing a magnesium alloy wheel hub, comprises the following steps: step 1, heating a magnesium alloy bar to 350-430° C. and keeping the temperature for 20 minutes; step 2, initially forging and forming the bar under a forging press, the forging speed is 6-15 mm/s; step 3, finally forging and forming the bar under a forging press, and the forging speed is 5-8 mm/s; step 4, testing the microstructure and material properties of the final forged blank to obtain the layered material property distribution on the thickness of the blank; step 5, according to the layered material property distribution on the thickness of the blank obtained in step 4, selecting the part that meets the requirements to make a magnesium alloy wheel hub. According to the different properties in the thickness direction of the blank, the spoke orientation of the magnesium alloy wheel can be quickly designed according to the needs, and the magnesium alloy wheel that meets the usage performance can be obtained, which greatly improves the design and processing efficiency.

    Abstract: The present disclosure belongs to the technical field of tests of automobile wheels and automobile chassis suspension systems, and provides a simulated pavement rotary drum and automobile test equipment. A simulated cobblestone pavement, and a simulated impact pavement, so that a testing pavement at a test field is reproduced; an impact load caused by the track pavement, the cobblestone pavement, and the impact pavement can be applied to wheels and a chassis system; and a road simulation test of wheels and a suspension system of an automobile can be performed on bench test equipment. As verified, the simulated pavement rotary drum of the present disclosure can reproduce the simulated track pavement at the test field; and the consistency of radial impact loads is greater than 95% at the same speed and under the same vehicle load operating condition.

    Abstract: The present disclosure belongs to the technical field of tests of wheels and automobile chassis suspension systems, and provides a transmission shaft automatic connection and disengagement device and test equipment. An input shaft drives a transmission shaft to rotate through a second connection shaft, a ratchet assembly, a first connection shaft and an output shaft so as to apply an acceleration torque, gears of the input shaft and the first connection shaft can be completely engaged and completely separated through extension and retraction of piston rods of a first group of air cylinders and a second group of air cylinders so as to achieve an effect that when a driving shaft needs to perform driving, a power system gets involved, and after driving is completed, the power system is cut off, and through the ratchet assembly, the transmission shaft can be prevented from driving a motor to work in reverse.
