伝達トルクは小さくなる。When the housing 1 rotates with a torque input of 1, this rotation is stopped by the clutch fiI due to the 9g disconnection resistance of the silicone oil.
39 to the clutch cylinder 37 and the hub member 11.13
Avoid rotating. At this time, the 9g breaking resistance of the silicone oil increases due to the slits 47 and 49 provided in the clutch cylinder 39, and a correspondingly large torque is transmitted. Also, if a large rotational difference occurs between the housing 1 and each output part U11.13, this rotational difference will be limited and a large 1 to 1 torque will be transmitted; if the rotational difference is small, this rotational difference will be allowed and transmitted. Torque becomes smaller.

7. When the overlapping margin L+ of 39, 12, that is, the opposing area is increased, the shear resistance of the silicone oil increases, the differential limiting ability increases, the transmitted torque increases, and it moves in the opposite direction, reducing the opposing area. As a result, the differential limiting ability decreases and the transmitted torque becomes smaller. At the same time, clutch cylinder 37.3
Due to the taper shape of No. 9, the mutual gap changes with the above operation, and the torque characteristics can be greatly changed with a slight operation. In this way, the torque transmission characteristics can be changed. Also, such adjustment is possible using viscous coupling 63.6.
5 can be performed independently.
