Roller assembly for a switch tongue used with a stock rail |
摘要 |
A roller assembly for a rail switch tongue used with a stock rail exhibiting reduced friction and resistance to vibration includes roller elements for supporting the switch tongue. Each roller element is supported by elastomer springs, one having a damping and the other having a supporting characteristic. The spring elements are mechanically coupled so that loading of the roller elements by the switch tongue causes a change in the spring length.
