Description

100% 低地板独立轮动力转向架双电机同轴两轮同步驱动机构
技术领域
本发明涉及一种使用在 100% 低地板轻轨车辆独立轮对动力转向架上的双电机同轴两轮同步驱动机构。
背景技术
100% 低地板轻轨车为了降低整车地板面高度，采用了独立轮轴桥装置，与传统有轴刚性轮对不同的是，同一车轴上的两个车轮可以相互独立的旋转，因此，在驱动一个车轮时，另一个车轮不会同步转动，将导致车辆脱轨。为了解决上述问题，有的转向架采用了同侧驱动方式，即采用单电机、双端输出的结构，通过前后两个齿轮箱驱动转向架同一侧的两个车轮，但这种驱动方式使其失去了传统转向架固有的自导向特性，往往轮缘磨耗严重，且在某一侧电机故障情况下容易发生脱轨事故。
发明内容
本发明的目的 在于既能够实现驱动力的传递，又使独立轮对具有与传统刚性轮对相同的自导向特性，降低轮缘磨耗，确保转向架运行安全可靠性。
为实现上述目的，本发明提供一种100%低地板独立轮动力转向架双电机同轴两轮同步驱动机构，其特征在于：包括牵引电机、齿轮传动装置、独立轮对， 每个车轮设置一套电机和齿轮传动装置，同轴两电机同步驱动， 电机轴作为牵引动力源，通过联轴器传动连接齿轮传动机构的输入轴，齿轮传动装置布置在转向架构架外侧，齿轮传动机构的输入轴上设一伞齿轮，该伞齿轮与中间轴上的另一伞齿轮啮合，中间轴上还设一中间轴齿轮，中间轴齿轮与输出轴齿轮啮合，一级输出轴连接车轮。
本发明 从牵引电机传递至齿轮传动装置的驱动扭矩可通过齿轮传递至车轮， 始终以同轴的两个牵引电机同步驱动为控制目标，当同轴两电机中的任一电机发生故障时，另一个电机立即停止动力输出，实现了独立轮轴桥装置同轴两轮同步驱动，使其具有与传统有轴式刚性轮对相同的轮轨关系特征，具有一定的自导向特性，从而降低轮缘磨耗，同时避免了因电机故障而导致脱轨的可能，提高独立轮轴桥运行安全性。
