摘要

PURPOSE: To provide a torque limiter device dampening the shock occurring at the end of deploying a deployable lengthening piece of a space instrument such as a solar generator without resorting to using a complex speed regulation or synchronization mechanism for deployment. CONSTITUTION: A limiter device 28a to be placed between each joint 12 and at least one of the adjacent elements 10a of a lengthening piece includes an elastic system such as a stack of Belleville washers 48a, and the elastic system presses the plate 24a of the joint 12 against the edge of the element 10a with a predetermined and adjustable force. At the end of deployment, the elastic system absorbs the energy of the shock by deforming, then it brings two pieces 24a, 10 back into contact with each other thus giving the lengthening piece with the desired rigidity. An accurate relative positioning is then ensured by a flexible plate 34a whose lateral edges are secured to each of the pieces 24a, 10.
