The invention provides a bearing for a railway vehicle, an axle box device, the railway vehicle and a control method, and the bearing comprises a bearing body suitable for connecting an axle of the railway vehicle to a bearing box; the detection part is mounted at the sealing position of the bearing body and is configured to detect the internal pressure of the bearing body; the first vent valve is mounted on the bearing body and is suitable for communicating the interior of the bearing body with the external environment under the condition that the internal pressure of the bearing body exceeds first preset pressure so as to release the internal pressure of the bearing body; and the second vent valve is mounted on the bearing body, and the second vent valve is opened to release the internal pressure of the bearing body under the condition that the internal pressure of the bearing body exceeds a second preset pressure within a first preset time, or the number of times that the internal pressure of the bearing body exceeds the second preset pressure within the second preset time reaches a preset number of times. And under the condition that the pressure intensity in the bearing body is reduced to be lower than the second preset pressure intensity, the second vent valve is closed.

    本公开提供了一种用于轨道车辆的轴承、轴箱装置、轨道车辆以及控制方法,轴承包括:轴承本体,适用于将轨道车辆的车轴连接在轴承箱上;检测部,安装在轴承本体的密封位置,被构造成检测轴承本体内部压强;第一通气阀,安装在轴承本体上,适用于在轴承本体内部压强超过第一预设压强的情况下,连通轴承本体内部与外部环境,以释放轴承本体内部压力;以及第二通气阀,安装在轴承本体上,在轴承本体内部压强持续第一预设时间超过第二预设压强,或者在第二预设时间内轴承本体内部压强超过第二预设压强的次数达到预设次数的情况下,第二通气阀开启,以释放轴承本体内部压力,并在轴承本体内部压强降至低于第二预设压强的情况下,第二通气阀关闭。
