A powertrain mounting structure

Abstract

The application discloses a power assembly mounting structure, comprising a power assembly and a first suspension, a second suspension, a third suspension and a fourth suspension connected to the power assembly, the power assembly having a first direction, a second direction and a third direction perpendicular to each other, the first suspension and the second suspension being arranged on one side of the power assembly along the first direction, the third suspension and the fourth suspension being arranged on the other side of the power assembly along the first direction, the first suspension and the third suspension being oppositely arranged, and the second suspension and the fourth suspension being oppositely arranged, the elastic centers of the first suspension, the second suspension, the third suspension and the fourth suspension being connected to form the center of a quadrangle, and the center of the quadrangle coinciding with the center of mass of the power assembly. The center of the quadrangle formed by the elastic centers of the four suspensions coincides with the center of mass of the power assembly, vibration is solved in six degrees of freedom, vibration in each degree of freedom is relatively independent, and the problem that the power assembly is not easy to install in the traditional three-point arrangement mode is solved.
