Title:
トルク伝達装置、制動装置および動力伝達装置
Document Type and Number:
Japanese Patent JP6465371
Kind Code:
B2
Abstract:
The present invention implements a torque transmission apparatus whose transmission torque is sufficiently small in a low differential motion range and large in a high differential motion range by using an ordinary viscous fluid without using a dilatant fluid that is difficult to handle. Outer plates have a doughnut-like disk shape and are attached to the inner circumferential surface of a case member. On the other hand, inner plates have a substantially arc shape and are swingably supported about a position at a distance from the center of rotation of a shaft. The inner plates are held at a first position, at which the interlocking area between the outer plates and the inner plates is small, by a tension coil spring when the relative rotational speed between the case member and the shaft is small, and, when the relative rotational speed between the case member and the shaft exceeds a predetermined value are pivotally moved toward the outer plates by the shearing force of a viscous fluid and held at a second position at which the interlocking area between the movable plates and the first plates is large.
