HORIZONTAL LOAD TEST ZIG FOR AIR SPRING OF RAILWAY VEHICLES

摘要

The invention lateral Durability testing of air spring provided between the body and the balance of the rail cars as relates to a railway vehicle air springs transverse to the running test jig enables to effectively carried out, the main body portion for supporting the air spring (1); A vertical actuator unit (3) for pressurizing the air spring in an upper portion of the body portion (1); Horizontal actuator unit 5 for applying a lateral displacement to the air spring; Rotation center (7) and for forming the rotation center point of the air spring actuator that is moved by the horizontal section (5); and characterized in that said provided with a, to perform the lateral durability test of the air spring and efficiently taking into account the vertical load and lateral load acting on the railway vehicle, with the air spring of the fact also makes it possible to perform more precisely a running test of the air spring by being able to set the condition to be tested.
