The invention relates to an integral type multi-connecting-rod electric drive axle and a vehicle, the electric drive axle comprises a hollow shaft driver, an axle tube, an upper pull rod, a lower pull rod and a transverse stabilizer bar, a rotor assembly of the hollow shaft driver is arranged outside two half shaft assemblies in a sleeving mode and is in transmission connection with the two half shaft assemblies, and the two half shaft assemblies extend out of the two ends of the hollow shaft driver; the rotor assembly and the half shaft assembly are coaxial; the two ends of the hollow shaft driver are connected with axle tubes, and the axle tubes are arranged outside the half shaft assemblies in a sleeving mode. The two upper pull rods are distributed at the two ends of the hollow shaft driver at intervals in the axis direction of the rotor assembly and used for connecting a vehicle body and an electric drive axle. The two lower pull rods are distributed at the two ends of the hollow shaft driver at intervals in the axis direction of the rotor assembly and used for connecting a vehicle body and an electric drive axle. The transverse stabilizer bar is used for connecting the vehicle body and the electric drive axle. The integral type multi-connecting-rod electric drive axle has the advantage of high transmission efficiency of a coaxial electric bridge, meanwhile, the problem of low-frequency polarization does not exist, and the riding comfort is improved through a multi-connecting-rod suspension structure.
本发明涉及一种整体式多连杆电驱动桥以及车辆,该电驱动桥包括空心轴驱动器、桥管、上拉杆、下拉杆及横向稳定杆,空心轴驱动器的转子组件套设于两个半轴总成外并与两个半轴总成传动连接,两个半轴总成从空心轴驱动器的两端伸出,转子组件与半轴总成同轴;空心轴驱动器两端连接有桥管,桥管套设于半轴总成外;两个上拉杆沿转子组件的轴线方向间隔分布于空心轴驱动器两端,用于连接车身与电驱动桥;两个下拉杆沿转子组件的轴线方向间隔分布于空心轴驱动器两端,用于连接车身与电驱动桥;横向稳定杆用于连接车身与电驱动桥。上述整体式多连杆电驱动桥具备同轴电桥高传动效率优势,同时不存在低频偏振的问题,多连杆的悬置结构提高了乘坐舒适性。
