In railway vehicles, rubber bushes have been widely used to fix oil dampers to axle boxes, truck frames and car bodies. The rubber bushes elastically support an oil damper to restrain generation of bending stress in the damper. Increasing the stiffness of the rubber bushes in the principal direction, however, is effective for improving responsiveness of the damper. This paper reports the newly-developed rubber bush which has higher stiffness in the principal direction and lower stiffness in the prying direction compared to those of the conventional one. Load test results demonstrate that the performance required in the specification is satisfied and the vehicle running test result shows that the rubber bush works effectively under the actual running conditions of railway vehicles.
