摘要： A valvetrain mechanism of an engine, including a drive shaft configured to rotate in synchronization with the engine, a link arm having a large end and a small end, the drive shaft being inserted into and passed through the large end, a valve lift control shaft disposed parallel to the drive shaft and having an eccentric portion, an oscillating arm disposed rotatably at the eccentric portion of the valve lift control shaft and interconnected with the small end of the link arm via a first rotation support point, a link rod interconnected with the oscillating arm via a second rotation support point positioned at a same side as the first rotation support point with respect to the valve lift control shaft, and an oscillating cam interconnected with the link rod via a third rotation support point and operated correspondingly with an operation of the drive shaft to thereby open a valve. A thickness of the small end of the link arm in a direction of the drive shaft is thinner than a thickness of the large end of the link arm in the direction of the drive shaft.
摘要翻译：发动机的气门机构包括构造成与发动机同步地旋转的驱动轴，具有大端和小端的连杆臂，驱动轴插入并穿过大端，气门升程控制轴平行于驱动轴设置并具有偏心部分，摆动臂可旋转地设置在气门升程控制轴的偏心部分处，并经由第一旋转支撑点与连杆臂的小端部互连，摆动臂经由与第一旋转支撑点相对于气门升程控制轴位于同一侧的第二旋转支撑点，以及通过第三旋转支撑点与连杆相互连接的摆动凸轮，并且相应地操作驱动轴从而打开阀。连杆臂的小端在驱动轴的方向上的厚度比连杆臂的大端在驱动轴的方向上的厚度薄。

摘要： A variable valve system for an internal combustion engine includes a drive shaft, a drive cam provided on the drive shaft, a link arm fitted on the outer periphery of the drive cam such as to rotate relative to the drive cam, a crank-shaped control shaft including a main shaft and an eccentric cam, an oscillating arm rotatably attached to the eccentric cam and oscillated by the link arm, and an oscillating cam connected to the oscillating arm via a link rod so as to actuate a valve. Lubricant is communicated from a main lubricant flow path in the drive shaft through three lubricant paths to sliding contact areas between the drive cam and the link arm, between the pin of the oscillating arm and the link arm, and between the eccentric cam and the oscillating arm.
摘要翻译：用于内燃机的可变气门控制系统包括驱动轴，设置在驱动轴上的驱动凸轮，安装在驱动凸轮的外周上的相对于驱动凸轮旋转的连杆臂，曲柄形控制轴，包括主轴和偏心凸轮，可旋转地附接到偏心凸轮并由连杆臂摆动的摆臂，以及通过连杆连接到摆动臂以便致动阀的摆动凸轮。润滑剂通过三个润滑剂路径从驱动轴中的主润滑剂流动路径传递到驱动凸轮和连杆臂之间的滑动接触区域，在摆动臂的销和连杆臂之间以及偏心凸轮与摆动之间臂。
