(未图示） 。 具体的， 设置在承载框架 1下部的第一关节轴承 21、 第二关节轴承 22和第五关节轴承 25的内圈和外圈均被外部结构有效的加紧在一起， 从而使得 第一关节轴承 21、 第二关节轴承 22和第五关节轴承 25能够承受较大的载荷， 以 满足车厢 100之间的连接强度要求。
[0022] 本发明提供的车厢铰接机构及有轨电车， 通过在承载框架的底部设置下部铰接 组件， 下部铰接组件的两个连接板通过同轴设置的两个关节轴承连接在承载框 架上， 车厢的铰接位置在同一轴线上， 有效的避免了承载框架因受力而产生较 大扭矩， 有效的提高了承载框架的抗疲劳性能， 第一连杆配合橡胶轴承和第三 关节轴承， 可以满足两个车厢之间的转动动作的要求， 而橡胶轴承还起到较好 的缓冲作用， 橡胶轴承可起到缓冲车厢纵向及横向冲击的作用， 且橡胶轴承与 承载框架的安装螺栓处均使用弹性圆柱销进行定位， 可避免螺栓受剪切力， 连 接方式更为可靠； 第二连杆配合第四关节轴承能够缓和车辆横向位移吋的冲击 并保持相连接两车厢之间的相对位置的保持稳定， 提高了有轨电车的可靠性。
