The invention provides a rubber suspension bushing, a motor suspension and an electric automobile, the rubber suspension bushing comprises an outer pipe and an inner pipe, the inner pipe is kept in the outer pipe and can move in the axial direction of the inner pipe, the rubber suspension bushing further comprises a limiting protrusion and a blocking part, the limiting protrusion is arranged on the outer circumferential wall of the inner pipe, and the blocking part is arranged on the outer circumferential wall of the inner pipe. The outer pipe extends outwards along the radial direction of the inner pipe; the blocking parts are connected with the inner wall of the outer pipe, extend towards the inner pipe in the radial direction of the inner pipe and are distributed on the two sides, in the axial direction of the inner pipe, of the limiting protrusions, and movable gaps are formed between the blocking parts and the limiting protrusions. According to the rubber suspension bushing, the limiting protrusion is arranged on the inner pipe, and the blocking part is arranged on the outer pipe, so that hard limiting of the suspension bushing in the axial direction is facilitated, the structure is simple, an external limiting structure does not need to be arranged, and the rigidity of the rubber suspension bushing in the axial direction and the radial direction is facilitated to be improved.

    本发明提供了一种橡胶悬置衬套及电机悬置和电动汽车,本发明的橡胶悬置衬套包括外管,以及保持在外管内部,并可沿自身的轴向窜动的内管,且该橡胶悬置衬套还包括限位凸起以及阻挡部,其中,限位凸起设置在内管的外周壁上,并沿内管的径向向外伸出;阻挡部与外管的内壁连接,并沿内管的径向,向内管的方向伸出,阻挡部分布在限位凸起沿内管轴向的两侧,且阻挡部与限位凸起之间形成有活动间隙。本发明所述的橡胶悬置衬套,通过于内管上设置有限位凸起,并在外管上设置有阻挡部,利于实现该悬置衬套在轴向上的硬限位,结构简单,无需设置外部限位结构,并有利于提升该橡胶悬置衬套在轴向及径向上的刚度。
