The invention relates to a double-layer vibration isolation suspension system of an electric vehicle, and belongs to the technical field of automobile design and manufacturing. The double-layer vibration isolation suspension system of the electric vehicle comprises a first left suspension, a first right suspension and a rear suspension which are arranged on the left side, the right side and the lower end of a power assembly; a bracket for supporting an electric device assembly is arranged above the power assembly; a second left suspension and a second right suspension are arranged on the leftside and the right side of the bracket; the first left suspension and the first right suspension are fixedly connected with the left side and the right side of the bottom of the bracket, the second left suspension and the second right suspension are fixedly connected with the left end and the right end of the bracket respectively, and the lower end of the second left suspension, the lower end of the second right suspension and the lower end of the rear suspension are fixedly connected with an automobile body. According to the double-layer vibration isolation suspension system of the electric vehicle, on the premise that the overall arrangement of an existing electric vehicle cabin is not changed, the suspension system is optimized, the high-frequency vibration isolation performance of thesuspension system is greatly improved in a double-layer vibration isolation mode, and the driving comfort is greatly improved.
Description
technical field [0001] The invention relates to the technical field of automobile design and manufacture, and more specifically, the invention relates to a double-layer vibration isolation suspension system for an electric vehicle. Background technique [0002] With the increasingly tense energy and the increasingly important environmental protection work, the country pays more and more attention to the development of electric vehicles. Compared with traditional vehicles, the main excitation methods of motors and engines are fundamentally different, and the structure of traditional suspension systems can no longer meet the NVH performance requirements of electric vehicles. Especially in terms of high-frequency vibration isolation performance, it cannot meet the vibration isolation requirements of users. Contents of the invention [0003] In order to solve the above-mentioned technical problems existing in the prior art, the object of the present invention is to provide a ...
