The invention discloses a bushing for suspending a pure electric vehicle power assembly. The bushing comprises an outer pipe and an inner core, the inner core is coaxially arranged in the outer pipe,the inner core and the outer pipe are in vulcanization connection through a rubber main spring, the rubber main spring has the advantages that the rubber main spring comprises an inner rubber connecting layer arranged on the outer wall of the inner core in a coating manner and an outer rubber connecting layer arranged on the inner wall of the outer pipe in a coating manner, the outer rubber connecting layer and the inner rubber connecting layer are connected through a rubber supporting layer, a vibration absorbing layer is arranged between the outer rubber connecting layer and the inner rubberconnecting layer, and the vibration absorbing layer is arranged on the rubber supporting layer in a protruding mode. The vibration absorbing layer is arranged between the outer rubber connecting layer and the inner rubber connecting layer, and the vibration absorption effect is achieved through the vibration absorbing layer, so the high-frequency dynamic rigidity of the bushing in the frequency band of 800-3000 Hz is obviously reduced, and the vibration isolation performance of the whole bushing is obviously improved.

    本发明公开了一种纯电汽车动力总成悬置用衬套,包括外管和内芯子,内芯子同轴设置在外管内,内芯子与外管之间通过橡胶主簧硫化连接,优点是橡胶主簧包括包覆设置在内芯子外壁上的内橡胶连接层和包覆设置在外管内壁上的外橡胶连接层,外橡胶连接层和内橡胶连接层之间通过橡胶支撑层相连接,外橡胶连接层与内橡胶连接层之间设置有吸振层,吸振层凸起设置在橡胶支撑层上。优点是在外橡胶连接层与内橡胶连接层之间设置一吸振层,通过吸振层起到吸振作用,使得衬套在800—3000Hz频段的高频动刚度得到明显下降,整个衬套的隔振性能得到明显提升。
