The invention relates to the technical field of automobile power assembly suspension systems, and discloses a novel full-frequency-band vibration isolation electric vehicle suspension cushion assembly which comprises a suspension vehicle body side support. The large suspension cushion is arranged on the suspension vehicle body side bracket; the large suspension cushion is arranged on the suspension vehicle body side bracket; the movable main side bracket is fixed on the large suspension cushion through a connecting bolt; and the small suspension soft cushion is fixed on the movable main side bracket. A novel large suspension cushion structure is adopted, a combined suspension cushion assembly composed of a plurality of high-frequency vibration isolation small suspension cushions is additionally arranged, the large suspension cushion is used for bearing the total load of a large-torque motor and plays a good vibration isolation role below 1000 Hz, and the high-frequency vibration isolation small suspension cushions are additionally arranged at 1000 Hz to 2000 Hz to achieve a good full-band vibration isolation effect. And the whole vehicle NVH performance of the new energy vehicle is improved.
