The invention provides a vehicle-mounted anti-derailment transverse limiting device and an early warning system thereof. The design thought of the anti-derailment limiting device is determined by analyzing the wheel-rail contact geometric state during derailment. In order to prevent the device from interfering with a steel rail in the running process of a train and ensure that the device can effectively limit transverse displacement when a wheel pair is lifted, the device structures in the transverse direction, the longitudinal direction and the vertical direction and the installation size range are specially designed. After a vehicle is provided with the transverse limiting device, the critical derailing speed is increased, and the limiting device can better prevent the vehicle from derailing.

    本发明提供了一种车载防脱轨横向限位装置及其预警系统。本发明通过分析脱轨时的轮轨接触几何状态,确定防脱轨限位装置的设计思路。为了避免装置在列车行驶过程中与钢轨发生干涉,并确保其能够在轮对抬起时有效地限制横向位移,对横向、纵向、垂向上的装置结构及安装尺寸范围进行了特有设计。车辆在安装了本发明的横向限位装置后,临界脱轨速度均有所提升,限位装置能够更好地起到防止车辆脱轨的效果。
