Parallel crank mechanism for use in internal combustion engine to transmit torque from eccentrically stored crankshaft, has discharging unit discharging oil flow coming out from space in axial direction of coupling elements

摘要

The mechanism (1) has a secondary disk (15) cooperated with an output unit i.e. transmission input shaft, where rotational torque is introduced into the output unit by the secondary disk. A set of coupling elements is arranged between a primary disk (13) and the secondary disk. An oil inlet is connected with each of the coupling elements in the primary disk. A discharging unit discharges flow of oil i.e. lubrication oil, coming out from a space in an axial direction of the coupling elements, where the coupling elements are movably arranged in the space. An independent claim is also included for a method for guiding oil in a parallel crank mechanism.
