在机车车辆中,为了减少磨耗部件和减轻日常的管理工作并改善结构隔音性能,目前已经广泛采用用橡胶制成的弹簧、弹性止挡和导向元件。此外,利用橡胶的减振性能,还可以在许多情况下省去专门的减振装置。本文将首先介绍目前用得最多的橡胶弹簧和导向元件,然后再叙述由铁道机车车辆研究所制造的并在试验台上和实际运用中经过多次考验的橡胶弹簧和导向元件。
In locomotives and rolling stock, springs, elastic stops and guide elements made of rubber are widely used at present in order to reduce the wear of parts and to reduce routine management and to improve the structural sound insulation. In addition, the use of rubber damping performance, but also in many cases eliminates the need for specialized damping device. This article will first introduce the most used rubber springs and guide elements, and then describe the rubber springs and guide elements manufactured by the Railway Rolling Stock Research Institute and tested several times on the test rig and in actual use.
