The invention relates to the technical field of new energy automobile motor suspension structures, and discloses a bearing type two-stage vibration isolation suspension structure and method.A suspension framework is provided with an embedded cavity structure, an inner threaded hole is formed in the bottom of an embedded cavity, and the embedded cavity is used for installing a first-stage vibration isolation rubber bushing; a second-stage vibration isolation rubber bushing mounting hole is further formed in the suspension framework and used for mounting a second-stage vibration isolation rubber bushing, so that the suspension framework is provided with a second-stage vibration isolation structure; the vibration of the high-voltage wire harness is attenuated by the first-stage vibration isolation rubber bushing and then is transmitted to the second-stage vibration isolation rubber bushing for attenuation again, so that the NVH performance of the whole vehicle is improved; one end of the connecting support is used for fixing the high-voltage wiring harness, the other end of the connecting support is used for abutting against the first-stage vibration isolation rubber bushing, the fastener penetrates through the first-stage vibration isolation rubber bushing to be matched with the inner threaded hole to fix the connecting support to the suspension framework, the suspension framework can serve as a bearing point of the high-voltage wiring harness, and the space utilization rate of suspension in a cabin is increased.
本发明涉及新能源汽车电机悬置结构技术领域,公开了一种承载式二级隔振悬置结构及方法,悬置骨架上设有嵌入腔体结构,嵌入腔体底部设置内螺纹孔,所述嵌入腔体用于安装一级隔振橡胶衬套;所述悬置骨架上还设有二级隔振橡胶衬套安装孔,用于安装二级隔振橡胶衬套,以使得悬置骨架具有二级隔振结构;高压线束的振动经过一级隔振橡胶衬套衰减后传递到二级隔振橡胶衬套再次进行衰减,从而提升整车的NVH性能;连接支架一端用于固定高压线束,另一端用于抵接一级隔振橡胶衬套,利用紧固件穿过一级隔振橡胶衬套与内螺纹孔配合实现将连接支架固定在悬置骨架上,使得悬置骨架可作为高压线束的承载点,提升了悬置在机舱的空间利用率。
