Title:
A coupling link and a multilink type crank mechanism for multilink type crank mechanisms
Document Type and Number:
Japanese Patent JP6141535
Kind Code:
B2
Abstract:
A coupling element for a multi-joint crank drive of an internal combustion engine includes a coupling lever having a first eye for a piston connecting rod, and a second eye for an articulation connecting rod. A bearing cover forms with the coupling lever a third eye for a crank pin. The coupling lever and the bearing cover are connected to each other by bolts which defined parallel longitudinal central axes. The coupling lever and the bearing cover abut each other at an outer periphery of the third eye at adjacent contact surfaces on both sides of the third eye to define a separating plane which extends through a center of the third eye at an acute angle with respect to a further plane which passes through the center of the third eye and extends perpendicular to the longitudinal central axes of the bolts.
