ABSTRACT:
The present invention concerns a variable-torque braking device. The device is characterized in that it includes a secondary control (14, 17) which allows exertion on a friction-lining pad (9) of an additional moving-system braking torque as a function of a variable command parameter which exerts on the friction-lining pad (9) a movable-system braking force or torque capable of linear variation, in addition to the constant braking torque or force furnished by a main control, as a function of the variable control parameter. The invention finds an application notably to braking forklifts.
