一种地铁第三轨平滑过渡膨胀接头
摘要：
本发明公开了属于机械装置及运输技术领域的一种地铁第三轨平滑过渡膨胀接头。该膨胀接头结合膨胀接头的温度补偿和列车受流器集电靴平滑过渡功能，可用于地铁第三轨中需要安装膨胀接头的区段。本膨胀接头加装了受流器集电靴平滑过渡机构，使受流器集电靴在经过膨胀接头时不会产生冲击，不仅能够实现膨胀接头的温度补偿功能，而且具有保护受流器集电靴的显著特点，本发明的膨胀接头适合于各种受流器集电靴的使用。
摘要（英）：

The invention discloses an expansion joint for smooth transition of a third rail of a subway, belonging to the technical fields of mechanical devices and transportation. The expansion joint combines the functions of temperature compensation of the expansion joint and the smooth transition of a collector shoe of a current collector on a train and can be used for a section needing to install the expansion joint in the third rail of the subway. According to the expansion joint, due to addition of a smooth transition mechanism of the collector shoe of the current collector, not only can the temperature compensation function of the expansion joint be realized, but also the expansion joint has the obvious characteristic of protecting the collector shoe of the current collector. The expansion joint disclosed by the invention is suitable for being used by collector shoes of various current collectors.
