    • A lightweight pushrod assembly for internal combustion engines, such as motorcycle racing engines, includes a top pushrod and a bottom pushrod which are joined by a pushrod tappet. The pushrod tappet is mounted for reciprocating movement in a pushrod stanchion, and the stanchion is secured to the engine such that support is provided to the pushrod assembly at a position near the middle of the entire pushrod assembly. The pushrod stanchion also provides part of a pushrod housing assembly, with additional upper and lower housings provided to enclose the upper and lower pushrods. The lower end of the top pushrod and the upper end of the bottom pushrod preferably engage the tappet in a ball and socket joint relation to allow limited radial movement of the top and/or bottom pushrods to minimize the stresses on the pushrods. The supported pushrod assembly may be provided in kits for installation of the pushrod assemblies on existing engines.
    • 用于诸如摩托车赛车发动机的内燃机的轻型推杆组件包括顶推杆和底推杆,它们由推杆挺杆连接。 推杆挺杆安装成用于在推杆支柱中往复运动,并且支柱固定到发动机,使得支撑件在靠近整个推动组件中间的位置处被提供到推动组件。 推杆支柱还提供了推杆式外壳组件的一部分,附加的上部和下部外壳用于封闭上部和下部推杆。 顶部推杆的下端和底部推杆的上端优选地以球窝接头关系接合挺杆,以允许顶部和/或底部推杆的有限径向运动,以最小化推杆上的应力。 可以在支撑的推杆组件中提供用于在现有发动机上安装推杆组件的套件。
