Abstract
A device for translationally maneuvering a structure able to move with respect to a fixed support, includes at least one rack and at least one output pinion which is driven by motor elements via a gear train borne by a chassis. At least one element of the gear train consists in a slave element borne by a shaft equipped with torque limiting elements collaborating with the chassis and having a limit torque which is determined so as to: immobilize the slave element in terms of rotation with respect to the chassis when its torque is below the limit torque to permit translational maneuvering of the mobile structure by the turning of the output pinion; and allow the slave element to rotate with respect to the chassis when its torque is higher than the limit torque, to avoid a static or dynamic overload being applied to the gear train.
