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: A self-centering device for a liner press-fit wheel may improve center alignment when liners are pressed in bolt holes of the wheel, may reduce rejects generated when bolt hole materials are pressed out by alignment failures, and may improve a press-fit yield.
