The connecting rod is attached at one end to a crankpin on the crankshaft and at the other end to a piston, through a piston pin or wrist pin.
连杆的一端与曲轴的连杆轴颈相连，另一端通过活塞销与活塞相连。
When the piston is moved by vacuum, its velocity changes in steps, for the mass of piston pin and rod are connected in turn.
当活塞在真空作用下运动时，由于活塞销和连杆的质量是依次连接的，活塞速度呈阶梯式变化。
The connecting rod is attached to the piston by the piston pin.
连杆与活塞的连接是采用活塞销。
The piston pinhole in the piston also serves as a bearing for the piston pin, which is used to connect the connecting rod.
在活塞中活塞销孔也同样为活塞销形支承面，其作用为连接连杆。
The piston pin fits through one side of the piston, through the small end of the rod, and then through the other side of the piston. It holds the rod firmly in place in the center of the piston.
活塞销贯穿活塞，把连杆小头与活塞连在一起，并将连杆保持在活塞中心的适当位置处。
The connecting rod little end is connected to the piston pin.
连杆小头连接着活塞销。
In trunk-piston engines, a horizontal pin within the piston is encircled by the upper end of the connecting rod. This by far the most common construction.
在筒状活塞式的发动机中，活塞与连杆上端通过一个水平销子连接。这是最常见的一种结构。
