摘要： A shackle assembly (66) includes a shackle bracket (68), wear pads (76,78), a shackle stop (92), shackle plates (69,70) and elastomer bushings (72,80). Shackle bracket (68) includes legs (88,90)forming portions thereof. Elastomer bushing (72,80) preferably includes voids vertically separated with respect to each other and the elastomer layer (97) preferably has a bowtie-shaped configuration. First redundancy feature has shackle stop (92) secured between the shackle plates (69,70). Shackle stop (92) provides longitudinal control of axle (53) in the event the opposite limb of the leaf spring (44) is broken, the vehicle is generally traveling in a given direction and the vehicle is subject to deceleration. Second redundancy feature has fingers (84,86) forming portions of the shackle plates (69,70), which provides longitudinal control of axle (53) under the same conditions, but when the vehicle is generally traveling in an opposite direction.
摘要翻译：卸扣组件（66）包括卸扣托架（68），耐磨垫片（76,78），钩环止动件（92），钩环板（69,70）和弹性衬套（72,80）。卸扣支架（68）包括形成其部分的腿（88,90）。弹性体衬套（72,80）优选地包括相对于彼此垂直分离的空隙，并且弹性体层（97）优选具有弓形构造。第一冗余特征具有固定在钩环板（69,70）之间的止挡块（92）。如果板簧（44）的相对的侧板断裂，车辆通常沿给定的方向行进并且车辆受到减速，则卸载挡块（92）提供轴（53）的纵向控制。第二冗余特征具有形成卸载板（69,70）的部分的手指（84,86），其在相同条件下提供轴（53）的纵向控制，但是当车辆通常沿相反方向行进时。
