Abstract
A mechanical transmission device for transmitting a threshold force, comprising first and second elements rotatably mounted relative to each other about an axis of rotation, and having a transmitter member interposed between them to constrain the two elements to rotate together when a torque is imparted to one up to a threshold torque beyond which the two elements become movable in rotation. The transmitter member has a first friction disk constrained to rotate with the first element, and a second friction disk facing the first disk. It also has a bearing member that is axially movable to press the disks together and against a bearing turntable of the first element under drive from a presser member. Finally, it has a rotary drive, interposed between the bearing member and the second element, which are arranged to cause the bearing member to move axially against the presser member during rotation.
