An embodiment of the invention provides a gearbox output coupling, a gearbox and a low-floor rail vehicle, and relates to the technical field of rail traffic. The gearbox output coupling comprises a hollow shaft, a first rubber ring and a wheel side flange. The hollow shaft is provided with a first end and a second end which are opposite, the second end is used for being in transmission connection with an output gear, the first end is flexibly connected with the wheel side flange through the first rubber ring, and the first rubber ring can achieve compensation for displacement and angle difference. The first rubber ring comprises metal blocks and a rubber portion, the multiple metal blocks are distributed at intervals in the circumferential direction, the rubber portion is formed between every two adjacent metal blocks in a vulcanization mode, in this way, the first rubber ring is of an integrated structure, installation is facilitated, the problems of misalignment and non-centering are not likely to occur after installation, and then the bearing capacity can be improved. Part of the multiple metal blocks is fixedly connected with the first end, the rest of the multiple metal blocks are connected with the wheel side flange, and therefore flexible connection between the wheel side flange and the hollow shaft is achieved.
本发明的实施例提供了一种齿轮箱输出联轴节、齿轮箱及低地板轨道车辆,涉及轨道交通技术领域。齿轮箱输出联轴节包括空心轴、第一橡胶环和车轮侧法兰。空心轴具有相对的第一端和第二端,第二端用于与输出齿轮传动连接,第一端通过第一橡胶环与车轮侧法兰柔性连接,第一橡胶环可实现对位移和角度差的补偿。第一橡胶环包括金属块和橡胶部,多个金属块沿圆周方向间隔分布,橡胶部硫化成型于相邻两个金属块之间,如此第一橡胶环为一体式结构,便于安装,安装后不易出现不对中、不对心的问题,进而有助于提高承载能力。多个金属块中的部分与第一端固定连接,多个金属块中的其余部分与车轮侧法兰连接,从而实现车轮侧法兰与空心轴的柔性连接。
