The invention relates to an improved pure electric road-rail car which mainly comprises a car body capable of bearing loads, road wheels powered by a storage battery and driven by a hub motor, rail steel wheels driven by gears and capable of running on a steel rail, a rotatable large arm used for switching different running states of the road and the rail, and a limiting device capable of automatically locking the large arm. The road wheel is characterized in that in a road state, the hub motor independently drives the road wheel to rotate. In a railway state, the road wheels rotate synchronously, and the driving gears coaxially mounted on the inner sides of the road wheels are transmitted to the meshed driven gears to drive the coaxially mounted rail steel wheels to rotate. When a highway state is switched to a railway state, the limiting device can automatically lock the large arm at a fixed position in a power-off state, and tight meshing transmission of the driving gear and the driven gear is guaranteed. When the railway state is switched to the highway state, the large arm can be unlocked only after the limiting device is powered on by the switching power supply, and the reliability and the safety when the vehicle is switched to the highway state from the railway state are guaranteed.

    本发明涉及一种改进型的纯电动公铁两用车,主要包括:可承载负载的车身,由蓄电池供电轮毂电机驱动的公路车轮,由齿轮传动的可在钢轨上行驶的轨用钢轮,用于切换公铁不同行驶状态的可旋转大臂,可自动锁定大臂的限位装置。其特征在于:在公路状态时,轮毂电机独立驱动公路车轮旋转。在铁路状态时,公路车轮同步旋转,由公路车轮内侧同轴安装的驱动齿轮传动给啮合的从动齿轮,带动同轴安装的轨用钢轮旋转。从公路向铁路状态切换时,限位装置可在断电状态自动将大臂锁定在固定位置,保证了驱动齿轮与从动齿轮的紧密啮合传动。从铁路向公路状态切换时,开关电源需给限位装置上电后大臂才能解锁,保证了车辆从铁路切换到公路状态时的可靠性和安全性。
