The invention discloses an electric automobile transmission shaft installation structure and an electric automobile. The structure comprises two transmission shafts which are symmetrically arranged. Each transmission shaft comprises a fixed shaft, an intermediate shaft, a sliding shaft and a connecting shaft; a rolling assembly is arranged on the fixed shaft, a sliding assembly is arranged on thesliding shaft, the fixed shaft is connected with one end of the intermediate shaft through the rolling assembly, and the sliding shaft is connected with the other end of the intermediate shaft throughthe sliding assembly; the sliding shaft and the connecting shaft are connected through a spline, and a spring pin is installed between the sliding shaft and the connecting shaft for axial limiting. The two transmission shafts and a shaft tube of a rear axle assembly are arranged in parallel, the fixed shaft of each transmission shaft is installed on the rear axle assembly, and the connecting shaft of each transmission shaft is installed on a speed reducer. And the speed reducer and thea driving motor are fixedly mounted on the automobile body through a suspension bracket assembly. The structure is compact and simple, vibration can be reduced, the structural reliability and assembly manufacturability are improved, power transmission is stable, and the problem that the market after-sales service of the whole vehicle is caused by power transmission is solved.

    本发明公开了一种电动汽车传动轴安装结构及电动汽车,该结构包括两个对称布置的传动轴,传动轴包括固定轴、中间轴、滑移轴以及连接轴;固定轴上设置有滚动组件,滑移轴上设置有滑移组件,固定轴通过滚动组件与中间轴的一端连接,滑移轴通过滑移组件与中间轴的另一端连接;滑移轴与连接轴之间通过花键连接,并且两者之间安装有弹簧销进行轴向限位;两个传动轴与后桥总成的轴管并列设置,其固定轴安装在后桥总成上,其连接轴安装在减速器上;减速器、驱动电机通过悬置支架总成固定安装在车身上。本发明的结构紧凑、简单,可减少振动、提高结构可靠性和装配工艺性,而且使得动力传动平稳,避免了因动力传动造成整车的市场售后问题的出现。
