The invention relates to a new energy vehicle motor assembly suspension system structure which comprises a motor suspension support, a motor suspension soft cushion assembly, a gearbox suspension support and a gearbox suspension soft cushion assembly, the two sides of a motor assembly are fixedly installed between longitudinal beams through the motor suspension support, and the gearbox suspension soft cushion assembly is fixedly installed between the longitudinal beams through the gearbox suspension soft cushion assembly. The whole motor suspension support is of an L-shaped structure, the side face of the motor suspension support is fixedly connected with a motor assembly, and the end of the motor suspension support is fixedly connected to the ventral face of a longitudinal beam of a frame through a motor suspension cushion assembly. The two sides of the gearbox assembly are fixedly installed between the longitudinal beams through gearbox suspension supports, the whole gearbox suspension supports are of an L-shaped structure, the side faces of the gearbox suspension supports are fixedly connected with the gearbox assembly, and the ends of the gearbox suspension supports are fixedly connected to the ventral faces of the longitudinal beams of the frame through gearbox suspension cushion assemblies. The motor suspension cushion assembly and the gearbox suspension cushion assembly are both of a vertical installation structure, and the assembly manufacturability is good; the motor suspension support and the gearbox suspension support are both L-shaped castings, the constraint modes are high and are both larger than 400 Hz, and the resonance risk with the excitation frequency of the motor is small.
