Abstract (en)
The present invention relates to an articulated lever actuation unit, comprising a body (11), inside which a control piston (12) is slidably associated to the body (11) along a sliding axis (A), the control piston (12) being connected or coupled to actuation means (15) able to exert a thrust force (P) on the control piston (12), where the control piston (12) is operatively coupled to a pivotable arm (14) by interposition of an articulated lever mechanism (13) in order to induce a rotational movement to the pivotable arm (14) about an axis of rotation (B) perpendicular to the sliding axis (A) following a sliding movement of the control piston (12), the pivotable arm (14) being moved between an open or non-operating position and a closed or operating position; the articulated lever mechanism (13) comprises a first (13a) and a second (13b) rod, the first rod (13a) being pivoted to a rod (12a) of the control piston (12) and to the second rod (13b), respectively, and the second rod (13b) being pivoted to the body (11) and setting the pivotable arm (14) in rotation; for each position of the pivotable arm other than the closed position, the thrust force (P) excited by the control piston (12) determines a variable clamping moment (M) at the axis of rotation (B) according to law M = k * P * AO where AO is the length of the second rod and k is a proportionality factor, and is characterized in that the length of the second rod ( AO ) is less than or equal to 32.8 mm and the proportionality factor (k) is comprised between 6.8 and 10.0 for a clamping moment comprised between 180 N m and 230 N m; or, the length of the second rod ( AO ) is less than or equal to 35.5 mm and the proportionality factor is comprised between 8.0 and 12.2 for a clamping moment comprised between 375 N m and 425 N m; or the length of the second rod ( AO ) is less than or equal to 30.5 mm and the proportionality factor (k) is comprised between 8.0 and 13.8 for a clamping moment comprised between 115 N m and 145 N m; or, the length of the second rod ( AO ) is less than or equal to 56.5 mm and the proportionality factor is comprised between 6.8 and 11.4 for a clamping moment comprised between 830 N m and 880 N m.
