The invention discloses a power assembly suspension with variable three-way rigidity and adjustable height and limiting distance. The suspension comprises an upper suspension assembly body and a lowersuspension assembly body, wherein the bottom of the upper suspension assembly body makes contact with the top of the lower suspension assembly body, a screw is arranged on the lower side of the uppersuspension assembly body, and the screw downwards penetrates into the edge of the top of the lower suspension assembly body from the upper suspension assembly body to prevent the upper suspension assembly body from rotating in the using process. The upper suspension assembly body comprises a first inner framework and a first outer framework. The lower suspension assembly body comprises a second inner framework and a second outer framework. The three-way rigidity, the height and the lower limiting distance of the suspension device are changed by rotating the connecting bolts; the upper limiting distance is changed by rotating the upper suspension assembly body, meanwhile, pressure and pressure reduction mixed stress of rubber is achieved, the compression rigidity and the tensile rigidity are basically the same, the development efficiency and quality of the product vibration isolation performance are guaranteed, various functions of the suspension can be guaranteed in the actual workingcondition, the structure is compact, and the reliability is high.

    本发明公开了一种三向刚度可变、高度及限位间距均可调的动力总成悬置,其包括上悬置总成及下悬置总成,所述的上悬置总成的底部与下悬置总成的顶部相接触,在上悬置总成的下侧设置螺杆,所述螺杆由上悬置总成向下穿入下悬置总成顶部边缘部阻止上悬置总成在使用时发生旋转;所述的上悬置总成包括第一内骨架及第一外骨架,所述的下悬置总成包括第二内骨架及第二外骨架,本发明通过旋转连接螺栓改变悬置装置的三向刚度、高度及下限位间距,通过旋转上悬置总成改变上限位间距,同时实现了橡胶的压、减混合受力,且压缩、拉伸刚度基本相同,既保证产品隔振性能的开发效率及质量,又可在实际工况中保证悬置的各项功能,结构紧凑,可靠性高。
