The invention provides a damping device of a coaxial electric drive axle. The damping device aims at solving the technical problem of axial movement of a motor in the prior art. The damping device comprises a driving disc, a driven disc, an axial damping assembly and circumferential damping assemblies. The driving disc and the driven disc are oppositely arranged and coaxially installed, the axialdamping assembly is an axial magneto-rheological damping shock absorber and comprises a first cylinder body, a first piston, a first coil and a first circulating valve, a first cavity is formed in thefirst cylinder body, magneto-rheological fluid is contained in the first cavity, and the first cylinder body is coaxially and movably arranged on the outer side of a sleeve in a sleeving manner; thesleeve and the first cylinder body are in dynamic seal, the first piston is fixedly connected to the outer side of the sleeve in a sleeving manner, the first piston is coaxially arranged in the firstcavity and is in dynamic seal with the first cavity, a first circulating groove is formed in the periphery of the first piston, the first coil is installed in the first circulating groove, and the first circulating valve is installed on the periphery of the first piston; and the circumferential damping assemblies are installed between the driving disc and the driven disc in the circumferential direction.

    本发明提供了一种同轴式电驱动桥的减振装置,以解决现有技术中电机轴向窜动的技术问题;包括主动盘、从动盘、轴向减振组件和周向减振组件;主动盘与从动盘相对设置且同轴安装,轴向减振组件为轴向磁流变阻尼减振器,其包括第一缸体、第一活塞、第一线圈和第一流通阀,第一缸体内部形成有第一空腔,第一空腔内盛装有磁流变液,第一缸体同轴活动套设于套管外侧,套管和第一缸体之间动密封,第一活塞固定套接于套管的外侧,第一活塞同轴内置于第一空腔并与其动密封,第一活塞的外周开设有第一流通槽,第一线圈安装于第一流通槽,第一流通阀安装于第一活塞的外周;周向减振组件周向安装于主动盘和从动盘之间。
