The present invention relates to an apparatus for testing the durability of a bushing. The apparatus comprises: a cylinder body having a first fluid filling part and a second fluid filling part communicating with each other; a downward piston installed in the cylinder body to be able to rise and lower along the first fluid filling part; a bushing gripper holding a bushing assembly and seated on the downward piston; a pressing member pressing the bushing gripper downward to restrict the flow of the bushing assembly, and moving the downward piston downward; and an upward piston installed in the cylinder body to be able to be raised and lowered along the second fluid filling part, and raised by the flow of a working fluid inside the cylinder body when the piston moves downward, so as to press the bushing assembly upward. Therefore, the reliability of test results can be ensured.
본 발명은 부시 내구성 시험장치에 관한 것으로, 제1유체충진부와 제2유체충진부가 연통되게 형성되는 실린더바디와, 실린더바디에 제1유체충진부를 따라 승강가능하게 설치되는 하향피스톤과, 부시조립체를 홀딩하여 하향피스톤에 안착되는 부시그리퍼와, 부시그리퍼를 하향 가압하여, 부시조립체의 유동을 구속하고, 하향피스톤을 하향 이동시키는 가압부재와, 실린더바디에 제2유체충진부를 따라 승강가능하게 설치되고, 하향피스톤의 하강 시 실린더바디 내부의 작동유체의 유동에 의해 상승되며 부시조립체를 상향 가압하는 상향피스톤을 포함하는 것을 특징으로 한다.
