摘要： A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam lobe is slidingly receivable of a slider member for variably engaging a central cam lobe, preferably a high-lift lobe. An elongate shaft extends through a transverse bore in the slider member and through a slotted passage in the slider member. In the follower body, the shaft is provided with bearings supporting first and second lateral roller followers on opposite sides of the body for variably engaging first and second preferably low-lift lateral cam lobes flanking the central cam lobe. A lost-motion spring urges the slider member into contact with the central lobe. A latch member driven by a piston selectively locks the slider member to the follower body such that the follower follows the motion of the central cam lobe. When the latch member is disengaged from the slider member, the member slides within the follower body, allowing the lateral rollers to engage and follow the lateral cam lobes. Preferably, the latching mechanism is provided as a pre-assembled cartridge unit.
摘要翻译：一种两步手指随动摇臂组件，包括随动体，该随动体在第一端具有用于接合液压间隙调节器的插座和用于接合阀杆的相对端的垫。通过发动机凸轮凸起的致动方向通过从动体的通道可滑动地接收滑块构件，用于可变地接合中央凸轮凸角，优选地是高升高凸起。细长轴延伸穿过滑动构件中的横向孔并且穿过滑动构件中的开槽通道。在从动体中，轴设置有支撑在主体的相对侧上的第一和第二横向滚子从动件的轴承，用于可变地接合位于中心凸轮凸角侧面的第一和第二优选低提升侧向凸轮凸角。松动弹簧促使滑动构件与中央凸起接触。由活塞驱动的闩锁构件选择性地将滑块构件锁定到随动体，使得跟随器遵循中央凸轮凸角的运动。当闩锁构件与滑动构件脱离接合时，构件在从动体内滑动，允许侧向滚轮接合并跟随侧向凸轮凸角。优选地，闩锁机构设置为预组装的盒单元。

摘要： A two-step roller finger follower including an elongate body having side walls defining coaxially disposed shaft orifices, a pallet end and a socket end interconnecting with the side walls to define a slider arm aperture, and a latch channel. The socket end is mountable to an hydraulic lash adjuster, and the pallet end is matable with a valve stem. A slider arm for engaging a high-lift cam lobe is disposed in the slider arm aperture and has a first end pivotably mounted to the pallet end of the body and the second end forming a slider tip for engaging an activation/deactivation latch. The latch is slidably disposed in the latch channel, and the latch has a nose section for selectively engaging the slider tip. A spool-shaped roller having first and second roller elements fixedly attached to the shaft is rotatably disposed in the shaft orifices, the roller being adapted to follow the surface motion of low-lift cam lobes. Preferably, the shaft is journalled in roller or needle bearings which extend between and through the first and second shaft orifices, being thus exposed to normal copious oil flow through the RFF.
摘要翻译：包括具有限定同轴设置的轴孔的侧壁的细长主体的两步辊指随动件，托板端部和与侧壁互连以限定滑动臂孔的插座端以及闩锁通道。插座端可安装到液压间隙调节器，托盘端可与阀杆配合。用于接合高升程凸轮凸角的滑动臂设置在滑块臂孔中，并且具有可枢转地安装到主体的托盘端的第一端，并且第二端形成用于接合启动/停用闩锁的滑动头。闩锁可滑动地设置在闩锁通道中，并且闩锁具有用于选择性地接合滑块顶端的鼻部。具有固定地连接到轴的第一和第二滚子元件的线轴形滚子可旋转地设置在轴孔中，该滚轮适于跟随低升程凸轮凸角的表面运动。优选地，轴被轴颈安装在在第一和第二轴孔之间延伸并穿过第一和第二轴孔的辊或滚针轴承中，从而暴露于通过RFF的正常大量油流。
