Abstract: 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.

Abstract: The invention provides a method for simulating real impact test of vehicle wheels, and the method is implemented using a system as follows: the system includes a vehicle used in wheel simulating real impact test, a road surface, a high-frequency lighting facility, a standard obstacle block, a high-speed camera, and a traction motor and steel cable. The method for simulating real impact test of vehicle wheels of the invention has the advantages that: the need for testing various types of wheels using one set of equipment can be satisfied by using a general type collision trolley, thereby avoiding the use of a corresponding real vehicle for each type of wheels in the test. This greatly reduces the test cost, ensures that the test condition is similar to the real vehicle condition, and can well simulate the performance of a real vehicle when meeting an obstacle.
