(54) Braking device for toggle-lever drive apparatuses


(57) The braking device (15, 16) for braking a rocking work arm (12) in toggle-lever drive apparatuses (10), comprises a hydraulic decelerator (17', 17") operating in correspondence with an operative position of the work arm (12), which is provided with a control rod (18) movable according to a longitudinal axis (A); the braking device (15, 16) further comprises an actuating arm (19', 19") connected to the rotatable drive shaft (13) of the work arm (12) and designed to act on the control rod (18) of the hydraulic decelerator (17', 17"). The control rod (18) of the decelerator (17', 17") and the actuating arm (19', 19'') have arched contact surfaces (20, 21) shaped and disposed in such a way that the actuating arm (19', 19") exerts a thrust force on the control rod (18) which remains substantially coaxial to the longitudinal axis (A) of the decelerator (17', 17").
