The invention provides a suspension device for a power assembly, an automobile and a method for installing the power assembly. The suspension device comprises a first connecting support arranged on the right side of the power assembly. The second connecting bracket is arranged on the left side of the power assembly; the first suspension is arranged on the right side of the vehicle body and used for being connected with the first connecting support; the second suspension is arranged on the left side of the vehicle body and used for being connected with the second connecting support; the positioning assembly is used for being arranged between the first connecting support and the first suspension and between the second connecting support and the second suspension so as to position the position of the power assembly and the position of the vehicle body in the front-back direction, and the suspension device can avoid the situation that a high-precision installation face is reserved on the power assembly or an installation characteristic support is additionally arranged; according to the suspension structure, the production and manufacturing cost is reduced, the installation operation is simplified, meanwhile, the first suspension and the second suspension used for bearing are not prone to being subjected to additional preload in the front-back direction, and the NVH performance of the whole vehicle is integrally improved.

    本申请提出了一种用于动力总成的悬置装置、汽车和安装动力总成的方法,悬置装置包括设置在动力总成的右侧的第一连接支架;设置在动力总成的左侧的第二连接支架;设置在车体的右侧的第一悬置,第一悬置用于与第一连接支架连接;设置在车体的左侧的第二悬置,第二悬置用于与第二连接支架连接;定位组件,定位组件用于设置在第一连接支架与第一悬置之间和用于设置在第二连接支架与第二悬置之间以定位动力总成与车体前后方向的位置,该悬置装置可以避免动力总成上留有精度较高的安装面,或者增加一个安装特征支架,降低生产制造成本,简化安装操作,同时使得用于承载的第一悬置和第二悬置在前后方向上不易受到额外的预载,整体提升整车的NVH性能。
