采用承载鞍弹性定位及常接触弹性摩擦旁承的可行性

Feasibility ot applying elastic guide on bearing adapter and the constant constact flexible frictional side bearing

本文对货车转向架承载鞍(或轴箱)的3种定位方式进行了分析,认为采用弹性定位可提高蛇形运动的稳定性,改善曲线通过性能。采用常接触弹性旁承也有助于转向架动力性能的改善,尤其是改善转向架的横向动力性能。

In this paper, three forms of bearing adapter(axlebox) guide on freight trucks are analysed. It istecognized that the adoption of elastic axle guide canimprove stability of hunting motion and performancen curving. The application of constant contact flexi.ble side bearing is advantageous in improving dynamicperformance of truck especially their lateral dynamicperformance.
