Description

纯电动车传动器输入轴、中间轴前后支撑结构
技术领域
本发明涉及一种纯电动车传动器输入轴、中间轴前后支撑结构。 
背景技术
众所周知，随着世界能源危机和环保问题日益突出，汽车工业面临着严峻的挑战：一方面，石油资源短缺，汽车是油耗大户，节节攀升的汽车保有量加剧了这一矛盾；另一方面汽车的大量使用加剧了环境污染，随着资源与环境双重压力下持续增大，发展新能源汽车以成为汽车工业发展的方向，其中发展电动汽车是最主要的，但目前纯电动汽车传动器噪音较大、转速低、寿命短。 
发明内容
为了解决电动汽车传动器的问题，本发明提供了一种纯电动车传动器输入轴、中间轴前后支撑结构。本发明采用的技术方案是：它主要包括中间轴、输入轴及自密封球轴承，中间轴与输入轴前后均由自密封球轴承支撑。 
本发明具有安装方便，使输入轴、中间轴获得高转速，承受大的径向载荷，有效地改善ECT整体的NVH，以配合纯电动车的静音特征等特点。 
附图说明
下面结合附图及实施例对本发明作进一步说明。 
附图为本发明结构示意图 
具体实施方式
如附图所示，本发明包括中间轴3、输入轴1、自密封球轴承4、自密封球轴承2组成，中间轴3由自密封球轴承2支撑，输入轴1前后由自密封球轴承4支撑。
