Abstract

A cooling mechanism for a flywheel assembly comprising a first flywheel (12), a second flywheel (30), and a clutch cover assembly (32), in which cooling holes (52) are provided in the inner peripheral part of the second flywheel (30) and substantially radial cooling grooves (50) for radially blowing out the air in the clutch cover assembly (32) exhausted from the cooling holes (52) are formed in front of the second flywheel (30). Cooling air circulation passages are formed with the provision of cooling holes (52) and atmospheric cooling air is efficiently fed into the clutch cover assembly (32) so as to cool the friction surface of the second flywheel (30). Further the blowing action of the cooling grooves (50) serves to actively exhaust the air in the clutch cover assembly (32) to the atmosphere through the cooling holes (52), whereby the pressure in the clutch cover assembly (32) becomes negative and ensures more active feeding of the atmospheric cooling air into the clutch cover assembly (32).

For example, in U.S. Patent Application No. 199,411, the circumferential edge of the finger portion of the diaphragm spring used in the clutch cover assembly is defined as follows.

Therefore, the space S has a negative pressure. As a result, the air inside the clutch force main body 33 is discharged into the space S, so that the inside of the main body 33 also has a negative pressure, and as a result, the outside air is exhausted. It is sent from the back of the ram spring 36 through the slit 43 in the direction of the arrow A, and is supplied to the inside of the main body 33. Then, due to the centrifugal action of the rotation of the clutch disk 34, the cold air flows into the clutch disk as indicated by the arrow B.

Due to the rotation of the wheel 30, the cold si groove 50 blows out the surrounding air and discharges it radially outward, so that the inner circumference on the rear side of the second flywheel 30 is removed. Neighboring parts have negative pressure. For this reason, the air that has absorbed the frictional aging inside the main body 33 is discharged to the outside of the main body 33 through the cold S1 52 as shown by the arrow C, and further cooled. It is transported by 50 and discharged to the atmosphere. As a result, the inside of the main body 33 becomes negative pressure, so that the cooling air of the atmosphere actively circulates in the main body 33, and the above operation is repeated.

However, the air inside the main body 33 is positively discharged to the atmosphere through the cooling port 52 by the air blowing action of the cooling groove 50, so that the inside of the main body 33 also has a negative pressure. In other words, it is possible to more actively supply the cooling air of the atmosphere into the main body 33.
