The invention provides an automobile power assembly suspension support which comprises a root portion connected with an auxiliary frame, an arm A connected with an automobile body longitudinal beam and an arm B connected with a power assembly suspension cushion are arranged on the two sides of the root portion, the arm A and the arm B meet the following formula: Fa * La = Fb * Lb, Fa is the load of the automobile body weight acting on the arm A when an automobile stands horizontally, Lb is the load of the arm A when the automobile stands horizontally, and Lb is the load of the arm A when the automobile stands horizontally. Fb is the load of the weight of the power assembly acting on the arm B when the vehicle stands horizontally, La is the horizontal distance between the connecting point of the arm A and the vehicle body and the central point of the connecting area of the root and the auxiliary frame, and Lb is the horizontal distance between the connecting point of the arm B and the power assembly suspension cushion and the central point of the connecting area of the root and the auxiliary frame. Through the matching design of the arm A and the arm B, the stress of the root is improved, the connecting position of the support and the auxiliary frame is not affected by bending moment, the strength and fatigue durability of the support and the strength and fatigue durability of the connecting position of the support and the auxiliary frame are effectively improved, the number of parts is reduced, the arrangement space is saved, and the weight and cost are also reduced.

    本申请提供一种汽车动力总成悬置支架,包括与副车架连接的根部,根部的两侧设有与车身纵梁连接的臂A以及与动力总成悬置软垫连接的臂B,臂A和臂B满足如下公式:Fa*La=Fb*Lb,其中,Fa是车辆水平静置时车身重量作用于臂A的载荷,Fb是车辆水平静置时动力总成重量作用于臂B的载荷,La为臂A与车身连接点和根部与副车架连接区域的中心点的水平距离,Lb为臂B与动力总成悬置软垫连接点和根部与副车架连接区域的中心点的水平距离。本申请通过对臂A和臂B的匹配设计,改善了根部的受力,使该支架与副车架连接处不受弯矩作用,有效提升该支架自身以及该支架与副车架连接部位的强度和疲劳耐久性能,减少了部件数量,节省了布置空间,也降低了重量和成本。
