The motor suspension is characterized in that the motor suspension comprises an outer shell and an inner pipe, the outer shell is provided with an inner cavity which is vertically through in the axial direction, the inner pipe is arranged in the inner cavity, an annular first outer pipe is arranged on the inner wall of the upper portion of the inner cavity, and an annular second outer pipe is arranged on the inner wall of the lower portion of the inner cavity; the inner pipe comprises an upper-section connecting part, a middle-section connecting part and a lower-section connecting part which are sequentially arranged from top to bottom in the axial direction, the upper-section connecting part is connected with the first outer pipe through a first rubber main spring in a whole ring shape in a vulcanization mode, and the lower-section connecting part is connected with the second outer pipe through a second rubber main spring in a whole ring shape in a vulcanization mode; an inner core is arranged in the inner pipe, and the upper end and the lower end of the inner core extend out of the outer shell. The main spring has the advantages that the structure is simple, and the whole-circle main spring on the two axial sides can provide a large shaft-diameter rigidity ratio and meanwhile has the enough length of the rubber main rib so as to ensure that the main spring has good fatigue performance.

    本发明公开了一种电机悬置,特点是包括外壳体和内管,外壳体具有沿轴向上下贯通的内腔,内管设置在内腔中,内腔的上部内壁上设置有环状的第一外管,内腔的下部内壁上设置有一环状的第二外管,内管包括沿轴向自上而下依次设置的上段连接部、中段连接部和下段连接部,所述的上段连接部与所述的第一外管之间通过整环状的第一橡胶主簧硫化连接,下段连接部与第二外管之间通过整环状的第二橡胶主簧硫化连接,内管内设置有内芯子,内芯子的上下两端分别伸出设置在外壳体的外部。优点是结构简单,轴向两侧的整周主簧能在提供较大轴径刚度比的同时有足够长的橡胶主筋长度以确保主簧有较好的疲劳表现。
