The invention relates to the field of new energy vehicles, in particular to an electric vehicle suspension system. A left suspension framework is connected with a front auxiliary frame, and a left suspension supporting arm is connected with a speed reducer through a left suspension support; a right suspension framework is connected with the front auxiliary frame, and a right suspension supportingarm is connected with a motor shell; a rear suspension cushion assembly is connected with a speed reducer shell and connected with the front auxiliary frame through a rear suspension support; the speed reducer and the motor form a power assembly; rubber bushings are arranged at the joint of the left suspension framework and the left suspension supporting arm and the joint of the right suspension framework and the right suspension supporting arm; the rear suspension cushion assembly is provided with a rubber bushing and is connected with the rear suspension support through the rubber bushing; and the center points of the three rubber bushings form a triangle, and the centroid of the triangle coincides with the centroid of the power assembly. The centroid of the triangle formed by the centerpoints of the three rubber bushings coincides with the centroid of the power assembly, rotation of the power assembly under the limit torque working condition is effectively limited, and the anti-torque effect is good.
本发明涉及新能源汽车领域,具体为一种电动汽车悬置系统,左悬置骨架与前副车架连接,左悬置托臂通过左悬置支架与减速器连接;右悬置骨架与前副车架连接,右悬置托臂与电机壳体连接;后悬置软垫总成与减速器壳体连接并通过后悬置支架与前副车架连接;减速器与电机构成动力总成;左悬置骨架与左悬置托臂的连接处、右悬置骨架与右悬置托臂的连接处均设有橡胶衬套;后悬置软垫总成设有橡胶衬套并通过橡胶衬套与后悬置支架连接;三个橡胶衬套的中心点构成三角形,所述三角形的形心与所述动力总成的质心重合。本发明三个橡胶衬套的中心点构成的三角形的形心与动力总成的质心重合,有效限制动力总成在极限扭矩工况下的转动,抗扭效果较好。
