AUTOMATIC DISPLACEMENT CONTROL DEVICE OF FATIGUE TESTER FOR STABILIZER BAR

摘要

An automatic displacement control device of a fatigue tester for a stabilizer bar is provided to precisely and rapidly adjust a vibration amplitude of the stabilizer bar by automatically adjusting the vibration amplitude during a fatigue test of the stabilizer bar. An automatic displacement control device(11) of a fatigue tester for a stabilizer bar includes a screw(110), a slide cam(111), a rotating axis(113), and a driving unit(114). The screw is rotatably installed by supporting both ends thereof to both ends of a center of a rotary disc(10). The slide cam is screw-coupled with the screw to be slid right and left according to rotation of the screw. One side end of a power transmitting member is connected to one side of the slide cam. The rotating axis is inserted into an inserting hole of a driving axis(16) so that both ends thereof are supported by a bearing(115). One side end of the rotating axis is gear-coupled with the screw. The driving unit is connected to the other side end of the rotating axis.
