Three-joint connector of burden simulation test stand for vehicle, has spacer that is provided between half spherical cavities which are provided at preset spacing

摘要

The three-joint connector has joint ball (3) that is mechanically fixed on fixing device (5) through a lever arm (4). A half spherical cavity (6) for joint ball is surrounded by centrally divided spherical cap (8). A half spherical cavity (7) is provided at preset spacing from half spherical cavity (6), and a spacer (10) is provided between the half spherical cavities. Independent claims are included for the following: (1) burden simulation test stand; and (2) three.
