The invention relates to an electric drive axle device and an automobile. The electric drive axle device comprises a differential mechanism, a planetary speed regulating mechanism, a first driving piece and a second driving piece, the planetary speed regulating mechanism is fixedly connected with the power input end of the differential mechanism through a gear shifting mechanism, and the first driving piece is in transmission connection with the planetary speed regulating mechanism through a first multi-stage gear speed reducing piece. The second driving part is in transmission connection with the power input end of the differential mechanism through the second multi-stage gear speed reduction part and the gear shifting mechanism in sequence. According to the electric drive axle device and the automobile, a new power transmission path is designed, power can be uninterruptedly provided through the second driving piece during gear shifting, it is guaranteed that the differential mechanism can always guarantee power output in the gear shifting process, and the efficiency of the system is improved; and under the condition that the first multi-stage gear speed reduction part and the second multi-stage gear speed reduction part are used for guaranteeing the large torque, the overall structure is simple and compact, the overall size is small, and arrangement and lightweight design of the whole vehicle are better facilitated.

    本申请涉及一种电驱动桥装置及汽车;电驱动桥装置包括差速器、行星调速机构、第一驱动件和第二驱动件,行星调速机构通过换挡机构与差速器的动力输入端固定连接,第一驱动件通过第一多级齿轮减速件与行星调速机构传动连接,第二驱动件依序通过第二多级齿轮减速件和换挡机构与差速器的动力输入端传动连接;本申请的电驱动桥装置及汽车,设计了一种新的动力传动路径,换挡时可通过第二驱动件不间断提供动力,保证在换挡过程中差速器始终能够保证动力输出,提升系统的效率,且在利用第一多级齿轮减速件和第二多级齿轮减速件保证自身具有较大扭矩的情况下,整体结构简单且紧凑,整体尺寸较小,更利于整车的布置和轻量化设计。
