The invention discloses a commercial vehicle engine suspension cushion assembly of a semi-surrounding structure, a suspension cushion is arranged in a suspension shell, the suspension cushion comprises a support inner core, the support inner core is vulcanized on a lower plate through a rubber body, and a mounting screw hole is formed in the support inner core; the lower plate is a U-shaped structure curved surface, first mounting planes are formed at the two ends of the lower plate, and mounting holes are formed in the first mounting planes; a U-shaped half-surrounded curved-surface-shaped cavity corresponding to the lower plate is formed in the middle of the suspension shell, and the end of the cavity extends outwards to form a fixing screw hole which corresponds to the mounting hole. After the suspension cushion of the lower plate of the U-shaped structure is matched with the shell of the cavity of the U-shaped semi-enclosed structure, the limiting of the suspension in the Y direction is enhanced, the problem that due to the fact that the gap of a limiting structure is large, the vibration amplitude of an engine in the Y-axis direction is large when a vehicle turns or runs in a curve mode is solved, the Y-direction limiting of the suspension is improved, and the vibration amplitude of the suspension cushion assembly of the engine is reduced.

    本发明公开了一种半包围结构的商用车发动机悬置软垫总成,所述悬置软垫设置在悬置外壳内,悬置软垫内包括支架内芯,支架内芯通过橡胶体硫化在下板上,支架内芯上设置有安装螺孔;所述的下板为“U”型结构曲面,下板的两端形成第一安装平面,第一安装平面上设置有安装孔;所述的悬置外壳中间设有和下板对应的“U”型半包围曲面状腔体,腔体的端部向外延伸出固定螺孔,和安装孔形成对应关系。“U”型结构下板的悬置软垫与“U”型半包围结构腔体的外壳配合后加强悬置在Y向的限位,解决因限位结构空隙大,导致车辆在转弯或曲线行驶时,发动机Y轴方向振动幅度大的问题,提高悬置的Y向限位,降低发动机悬置软垫总成的振动幅度。
