摘要： Piston rod assembly includes a piston head and rod which are formed separately and subsequently jointed together by injecting adhesive through a porting passage in the piston head into an annular space formed by an internal groove in the piston head and an external surface of the rod to provide a bonded joint therebetween. The piston head includes a radially enlarged center dam portion and a pair of reduced diameter end portions extending coaxially from opposite sides of the center dam portion. The internal groove extends axially beyond opposite sides of the center dam portion for a substantial portion of the length of the reduced diameter end portions. The reduced diameter end portions are externally tapered radially inwardly from opposite sides of the enlarged center dam portion toward opposite ends of the reduced diameter end portions to provide a gradual build-up of stiffness in the piston head from the opposite ends of the bonded joint toward the middle. Also, integral rod sleeve portions extend from opposite ends of the reduced diameter end portions over a substantial portion of the length of the rod to provide a barrier around the rod impermeable to hydraulic fluid.
摘要翻译：活塞杆组件包括活塞头和杆，它们分别形成并且随后通过将粘合剂通过活塞头中的移动通道注入由活塞头中的内部沟槽和杆的外表面形成的环形空间中而接合在一起，以提供它们之间的接合接头。活塞头包括径向扩大的中心坝部分和从中心坝部分的相对侧同轴延伸的一对缩径的端部部分。内凹槽在直径较小的端部的长度的大部分上轴向地延伸超过中心阻挡部分的相对侧。缩小的直径端部从扩大的中心坝部的相对侧径向向内径向向内径向向内延伸，朝向缩径直径端部的相对端，从而从接合接头的相对端向活塞头逐渐积聚起刚度中间。此外，一体式杆套筒部分从直径较小的端部的相对端部延伸到棒的长度的大部分上，以在液压流体不可渗透的杆周围提供屏障。
