The invention relates to a driving structure and an electric drive axle. The driving structure comprises a first driving part, a first speed reducing mechanism, a planetary speed regulating mechanism and a second driving part. The first reducing mechanism is in transmission connection with the output end of the first driving part; the planetary speed regulating mechanism comprises a sun gear, a planet carrier and a planet gear, the planet carrier is fixedly sleeved with the planet gear, the planet gear is meshed with the sun gear, the sun gear is in transmission connection with the first speed reducing mechanism, and the planet carrier is used for being fixedly connected with the input end of the differential mechanism; the output end of the second driving piece is in transmission connection with the input end of the differential mechanism. A new power transmission path is designed, in the time from gear disengagement to successful gear shifting, power is not interrupted, the efficiency of a system is improved, the driving feeling of a driver is improved, the car sliding risk in the gear shifting process is reduced, the personal safety of the driver is guaranteed, the structure is simple and compact, the overall size is small, and the cost is low. And arrangement and lightweight design of the whole vehicle are facilitated.
本申请涉及一种驱动结构和电驱动桥,包括第一驱动件、第一减速机构、行星调速机构以及第二驱动件。第一减速机构和第一驱动件输出端传动连接;行星调速机构包括太阳轮、行星架和行星轮,行星轮固定套设在行星架上,行星轮与太阳轮啮合,太阳轮和第一减速机构传动连接,行星架用于与差速器的输入端固定连接;第二驱动件输出端和差速器的输入端传动连接连接。本申请设计了一种新的动力传动路径,在摘挡后到成功换挡的时间内,动力是不中断,提升系统的效率,增加了驾驶人员的驾驶感受,减少了换挡过程中的溜车风险,保障了驾驶人员的人身安全,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。
