The invention discloses a suspension system of an automobile and the automobile, and relates to the technical field of automobile equipment manufacturing. The device comprises a power assembly; at least four suspension devices which are arranged on an auxiliary frame of the automobile, the power assembly is connected with the auxiliary frame through the suspension devices, the elastic centers of all the suspension devices can form a polygon, and the centroid of the polygon basically coincides with the centroid of the power assembly. According to the suspension system provided by the embodiment of the invention, through the arrangement of four-point suspension, the torque needing to be borne by each suspension structure is reduced, and the bearing capacity of the suspension system is enhanced. According to the suspension system provided by the embodiment of the invention, the four-point suspension is arranged, and the center point of the quadrangle formed by the elastic centers of the rubber main springs of the four-point suspension is arranged near the mass center of the motor assembly, so that the stress of the four suspension main springs is relatively average, and the bush structure and the three-dimensional rigidity can be basically the same; and the limiting effect of the suspension system is enhanced.

    本发明公开了一种汽车的悬置系统及汽车,涉及汽车装备制造技术领域,该装置包括动力总成;至少四个悬置装置,其设于汽车的副车架上,所述动力总成通过所述悬置装置与所述副车架连接,所有的所述悬置装置的弹性中心可构成一个多边形,所述多边形的形心与所述动力总成的质心基本重合。本发明实施例提供的悬置系统中通过四点悬置的布置,减少了每个悬置结构所需要承载的力矩,加强了悬置系统的承载能力。本发明实施例提供的悬置系统中通过将四点悬置的布置,并将四点悬置橡胶主簧弹性中心组成的四边形中心点设置在电机总成质心附近,使得使四个悬置主簧的受力相对平均,衬套结构和三向刚度可以做到基本相同,悬置系统的限位效果得到增强。
