摘要： The disclosure discloses a magnesium alloy for wheels, comprising in mass percentage: Al: 2-3.0 wt. %; Zn: 0.5-1.0 wt. %; Mn: 0.3-0.5 wt. %; Ce: 0.15-0.3 wt. %; La: 0.05-0.1 wt. %, the balance is Mg. The magnesium alloy of the present invention takes Al element and Mn element as main alloying elements, supplemented by trace Ce and La elements as alloying process, and the nano-scale Mn-rich precipitated phase obtained during homogenization and the segregation of rare earth elements Ce and La at the interface and grain boundary of Mn-rich precipitated phase are used to inhibit the coarsening during extrusion and forging, so as to improve the strength and plastic deformation ability of the alloy.

摘要： The present disclosure belongs to the technical field of tests of wheels and automobile chassis suspension systems, and provides a universal suspension and test equipment for an automobile chassis simulation road test. A simulated dashpot is movably connected to a simulated shock absorption tower; a simulated steering link and a simulated lower control arm are both movably connected to a backboard; and the simulated dashpot, the simulated steering link, and the simulated lower control arm are all assembled with corresponding mounting holes in a steering knuckle. Simulated parts with adjustable lengths and positions are used to replace an original vehicle's dashpot, steering link and lower control arm of a suspension, so that by means of adjusting lengths and angles of all the parts of the test suspension, the universal suspension can be applicable to the spatial hard point requirements of most current Macpherson suspensions.
