摘要

The multijoint crank drive (8) has multiple coupling elements (9), which are rotatably mounted on lifting pins (16) of a crank shaft (2), and multiple link connecting rods (12) rotatably mounted on lifting pins of an eccentric shaft (6). Each of the coupling element is pivotally connected with a piston connecting rod (4). The link connecting rod has a lubricant collecting channel for supplying lubricant to a connecting rod bearing (17) provided in the connecting rod eyes (14,15). The lubricant collecting channel is arranged on a connecting rod (13) and opens into the connecting rod bearing.
