Abstract:
1. Braking system (S), intended to be fitted to a mechanism, with one or more rotating members ( 34 ), comprising a toothed wheel ( 6 ), connected rotationally with respect to at least one rotating member ( 34 ) to be braked, and a worm ( 8 ), driven rotationally by a motor ( 5 ) upon the rotation of the rotating member ( 34 ), this worm ( 8 ) being permanently in mesh with the toothed wheel ( 6 ); characterized in that the worm ( 8 ) is contained in a bore with a diameter close to that of the worm ( 8 ), wherein the system comprises specific energy absorption/dissipation means ( 10 , L, 12 ; 13 to 16 ; 19 to 21 ), in addition to the teeth of the wheel ( 6 ) and the thread of the worm ( 8 ), said specific energy absorption/dissipation means comprise a sliding mounting of the worm in the bore and energy absorption/dissipation means ( 10 , L, 12 ) associated with this worm ( 8 ) and actuated by it upon its sliding, said associated energy absorption/dissipation means comprise: a liquid (L) contained in the space delimited by at least one piston ( one or more paths for this liquid (L) to escape upon the sliding of the worm (
