WET CLUTCH MECHANISM AND TORQUE TRANSMISSION MODULE INCLUDING THE WET CLUTCH MECHANISM

摘要

The invention relates to a wet clutch mechanism (10) for a torque transmission module comprising at least a first clutch (E1), of the multi-disc type, controlled to selectively couple a drive shaft to a first driven shaft. The first clutch (E1) comprises: a torque input disk holder (20) arranged to be linked in rotation with the driving shaft along an axis of rotation (O) via a hub (14) entry; - a multi-disc assembly attached to the input disc holder; - a guide bearing (150) inserted in a cylindrical support portion (23) of the input disc holder (20) and configured to support the radial forces of the wet clutch mechanism, - a lubrication ring (60 ) of the clutch in which lubrication lines (61) are interposed axially between the guide bearing and the inlet hub (14), said lubrication ring (60) comprising a threaded portion (62).
