The invention relates to a vehicle engine suspension bracket assembly. The vehicle engine suspension bracket assembly comprises an upper vibration reducing pad, a support plate and a lower vibration reducing pad laminated in sequence from top to bottom; a dumbbell-shaped airbag is mounted between the upper vibration reducing pad and the lower vibration reducing pad; a thin waist part of the airbag is inserted in a corresponding through hole on the support plate; risers at two ends of the airbag are respectively stopped at the corresponding end hole edges of the through hole; and two ends of the airbag are preset in the bottom of the upper vibration reducing pad and in the top of the lower vibration reducing pad. The upper vibration reducing pad and the lower vibration reducing pad are connected by the dumbbell-shaped airbag; the airbag achieves elastic buffer and support effects on one of the upper vibration reducing pad and the lower vibration reducing pad, and achieves an elastic expansion effect on the other one; through airflow movement between the risers at two ends of the airbag, a pressed end of the airbag is softened, and an unpressed end is hardened; the upper vibration reducing pad and the lower vibration reducing pad are both participated in vibration reducing actions; and through the principle of the upper vibration reducing pad and the lower vibration reducing pad sharing the vibration pressure, the vibration reducing rigidity in one-way vibration is reduced, and the vibration reducing effect is improved.
