The invention provides an engine power assembly suspension system of a heavy truck. The engine power assembly suspension system comprises a mounting seat 1 and a core body arranged on the mounting seat. The core body comprises a rubber main spring and an inner framework. The movement gap and the buffer pad structure can relieve rigidity changes in all movement directions, and the NVH performance of the whole vehicle under the severe working condition can be remarkably improved; yawing motion of the power assembly around the Z axis of the whole vehicle can be well restrained, and meanwhile the fatigue endurance life of rubber can be remarkably prolonged; the structure is compact and stable, the weight and the size are small, under the condition that the bearing capacity is not changed, the device can be suitable for vehicle models with compact installation space requirements, and the cost is greatly reduced.
本发明提供一种重型卡车发动机动力总成悬置系统,包括:安装座1以及设置在安装座上的芯体。其中,芯体包括:橡胶主簧及内骨架。本发明运动间隙以及缓冲垫结构可舒缓所有运动方向的刚度变化,可以显著改善整车在恶劣工况下的NVH性能;可良好地抑制动力总成绕整车Z轴的横摆运动,同时可显著地改善橡胶的疲劳耐久寿命;结构紧凑、稳定,重量及体积小,在不改变承载能力的情况下可以适用于对安装空间要求紧凑的车型,并较大幅度地降低成本。
