Two-piece type prestress hanging basket device of shimmy test bed

The invention provides a two-piece type prestress hanging basket device of a shimmy test bed. Comprising a main body stand column (1), a sliding plate (2), a vertical loading cross beam (3), a hanging basket component (4), a loading hydraulic cylinder (12) and a force measuring platform (14), according to the device, 16 groups of roller sliding blocks (6) are connected with a sliding plate (2) of a main body stand column (1) in a sliding mode, the 16 groups of roller sliding blocks (6) guide vertical movement of a hanging basket component (4), and horizontal force borne by the hanging basket component (4) is transmitted to the main body stand column (1). A limiting hole (8-1) is formed in an upper bearing plate (8) of the hanging basket component (4), and when a tire bursts, a limiting screw (13) pulls the hanging basket component (4) through the limiting hole (8-1), so that the tire is prevented from being excessively pressed downwards. Compared with a traditional welding type hanging basket device, the devi
