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 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 field of automobile chassis suspension system tests, and provides fatigue test equipment for an automobile chassis simulation road test. The fatigue test equipment can simultaneously test the simulation road test fatigue durability of automobile chassis parts such as the wheel and suspension system and the like, ensures that a test state of the tested wheel and suspension system is close to a real automobile state, and simulates and reproduces a load which an automobile chassis bears in the real road running process in a laboratory.
