DEVICE FOR HANGING A LOAD SUCH AS AN EMPORT UNDER AN AIRCRAFT

摘要

The present invention relates to a device (1) for attaching a load under an aircraft comprising: - an upper ball joint (10) comprising rollers (13) that can move radially arranged in a tubular body which is movable axially (11), - a lower ball joint (20) which can be connected to the first ball joint (10) by means of the rollers (13), - a piston (14) adapted to lock the rollers spaced apart radially (13) when the latching device (1) is in the locked position, - a system for the generation of prestress (30) intended to maintain the connection between the two balls in the retracted position of locking the attachment device (1), characterized in that the generation system of prestressed (30) comprises a hydraulic chamber of the prestress (31) and an electromechanical actuator (35) adapted to axially block the said tubular body (11) in the retracted position for locking the coupling device (1) so as to maintain the force generated by the hydraulic pressure in the hydraulic chamber (31), once said pressure, withdrawn.
