具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的轨道车辆的非驱动桥1。
如图1-图13所示，根据本申请实施例的轨道车辆的非驱动桥1包括桥主体100、走行轮210、导向框220、水平轮和连杆组件300。
桥主体100与轨道车辆的车架相连。走行轮210可沿其轴向旋转且可左右摆动地安装在桥主体100上(左右方向如图1中的箭头C所示)，走行轮210支撑在轨道车辆所行驶的轨道梁2上。导向框220在水平方向上相对桥主体100可转动地安装在桥主体100上。水平轮设在导向框220上。连杆组件300包括第一横拉杆310和第二横拉杆340，第一横拉杆310可枢转地安装在导向框220上，第二横拉杆340分别与第一横拉杆310和走行轮210传动连接，在轨道车辆左转时，水平轮通过与轨道梁2的配合带动导向框220摆动，并带动第一横拉杆310一同运动，第二横拉杆340在第一横拉杆310的带动下驱动走行轮210向左摆动，在轨道车辆右转时，水平轮通过与轨道梁2的配合带动导向框220摆动，并带动第一横拉杆310一同运动，第二横拉杆340在第一横拉杆310的带动下驱动走行轮210向右摆动。
本领域的技术人员可以理解的是，“走行轮210向左摆动”是指走行轮210在轨道车辆上的前端相对后端向左摆动，“走行轮210向右摆动”是指走行轮210在轨道车辆上的前端相对后端向右摆动。
这里需要理解的是，“第二横拉杆分别与第一横拉杆和走行轮传动连接”可以做广义理解，包括第二横拉杆与第一横拉杆和走行轮直接连接，也包括第二横拉杆与第一横拉杆和走行轮通过其他传动结构间接连接。
下面参考附图描述根据本申请实施例的非驱动桥1的工作过程。
轨道车辆行驶时，水平轮沿着轨道梁2内侧运行，当非驱动桥1需要转向时，水平轮受到轨道梁2的作用，水平轮带动导向框220转动，并带动第一横拉杆310，第二横拉杆340在第一横拉杆310的带动下驱动走行轮210摆动，使走行轮210与轨道梁2的转弯方向相适配，实现非驱动桥1的自转向功能，从而便于轨道车辆的转向。
根据本申请实施例的轨道车辆的非驱动桥1，通过设置导向框220和连杆组件300，连杆组件300分别与导向框220和走行轮210传动连接，可以在轨道车辆转弯时，水平轮会先后受到呈弯道的轨道梁2的导向作用，从而可以利用水平轮与轨道梁2的配合驱动导向框220相对轨道车辆转动，并进一步利用导向框220带动连杆组件300转动，最终利用连杆组件300驱动走行轮210摆动，相比相关技术中的轨道车辆，能够实现非驱动桥1的自导向功能，例如可以使轨道车辆的每节车厢实现单独运行，这样可以随意增减组装车厢，便于提高轨道车辆的灵活性和变化性，便于提高轨道车辆的适应能力，便于提高轨道车辆的使用范围，便于轨道车辆的使用。
并且，通过设置导向框220和连杆组件300，可以减小非驱动桥1转向时的阻力，不仅可以保证轨道车辆在轨道梁2上顺畅行驶，而且可以实现轨道车辆的高速导向转弯，便于提高轨道车辆的行驶速度，提高轨道车辆的工作性能。
此外，通过设置导向框220和连杆组件300，导向框220和连杆组件300能将转向力分散给非驱动桥1不同的零部件，相比相关技术中的轨道车辆，可以避免单一零部件受力太大而断裂，提高轨道车辆行驶的可靠性和稳定性，可以保证轨道车辆的行驶安全。
因此，根据本申请实施例的轨道车辆的非驱动桥1具有能够自导向、适用性强等优点。
