种双磨耗板弹性旁承

本发明涉及种双磨耗板弹性旁承，该弹性旁承包括并排安装在铁路车辆转向架上的高旁承和低旁承，其中，高旁承包括高旁承体和安装在高旁承体顶部的高旁承磨耗板，低旁承包括低旁承体和安装在低旁承体顶部的低旁承磨耗板；高旁承磨耗板的摩擦系数大于低旁承磨耗板的摩擦系数。本发明可以广泛应用于采用全旁承承载方式的铁路车辆转向架上。本发明的双磨耗板弹性旁承，高旁承和低旁承均采用磨耗板提供转向阻力矩，摩擦系数更加稳定，避免了滚子翘起等问题的发生；且两种旁承盖板的磨耗板安装接口尺寸分别采用不同数值，使高、低旁承磨耗板在安装时不能互换，达到防误装的目的，安装简单方便。 The invention relates to a dual wearing plate elastic side bearing, which comprises a high side bearing and a low side bearing that are parallelly mounted on a bogie of a railway vehicle, wherein the high side bearing comprises a high side bearing body and a high side bearing wearing plate mounted on the top portion of the high side bearing body; the low side bearing comprises a low side bearing body and a low side bearing wearing plate mounted on the top portion of the low side bearing body; and the friction coefficient of the high side bearing wearing plate is larger than that of the low side bearing wearing plate. The dual wearing plate elastic side bearing can be widely applied to the bogie of the railway vehicle in which a full side bea
