FLYWHEEL, PARTICULARLY FOR MOTOR VEHICLES

摘要

A flywheel comprising two coaxial members (12, 14) including a first member (12) designed to be rotationally integral with a drive shaft such as the crankshaft of an internal combustion engine, and a second member (14) designed to be connected with a driven shaft such as the input shaft of a gearbox. Said members (12, 14) are coaxially mounted via a bearing (28) such as a ball bearing, and coupling means (32, 58) are provided to couple the second member (14) to the first member (12). Said second member (12) forms the reaction plate (12) of a friction clutch and has, for this purpose, a friction surface comprising ventilation holes (4) in the region of the bearing (28). The ventilation holes (4) open into the bottom of a groove (5) provided in the second member (14) around the inner edge of its reaction plate (26) radially above the bearing (28) for collecting a lubricating agent such as oil escaping from the centre of the flywheel. The flywheel may be used in motor vehicles.
