The invention provides a gearbox auxiliary suspension cushion assembly for a heavy truck. The gearbox auxiliary suspension cushion assembly comprises an elastic lining, a cross beam structure and a circular outer sleeve structure. By the adoption of the elastic lining structure, a power assembly has enough displacement in the radial direction of the elastic lining and is not prone to colliding with a rigid framework, the rigidity of an E-point rubber elastic body can be fully reduced, and a gearbox shell is protected; the cylindrical elastic lining structure is adopted, so that the rigidity of a rubber main spring can be effectively reduced, excessive displacement of an outer framework can be restrained in all directions, and the fatigue cracking problem of a rubber vulcanization structure is solved; and enough tolerance capability can be ensured, and no load effect is ensured in a static load working condition and a constant-speed driving working condition.
本发明提供一种重型卡车用变速箱辅助悬置软垫总成,包括:弹性衬套以及横梁结构、圆形外套管结构。采用弹性衬套结构,使动力总成沿着弹性衬套的径向有足够的位移量,不易撞到刚性骨架,可充分降低E点橡胶弹性体的刚度,保护变速箱壳体;采用了圆柱形的弹性衬套结构,不仅可有效地降低橡胶主簧的刚度,而且还可以在所有方向约束外骨架的过量位移,消除橡胶硫化结构的疲劳开裂问题;可以确保有足够的容差能力,确保在静载工况和匀速行驶工况不受载荷作用。
