<p>The device substantially comprises a hydraulic cylinder (1) for activating the clutch and a control unit (4) adapted to supply pressurized oil to the aforesaid cylinder; this unit comprises a structure (17) in which a first (18) and a second (19) cylindrical cavity are set side by side, the first of which has a greater diameter than the second; a pair of pistons (21, 22) securely fixed to each other, free to move inside said cavity and defining a first (25) and a second (28) chamber, the latter of which is linked to the hydraulic activating cylinder; an activating terminal (32) free to move axially in the same direction as the pistons, connected to the clutch pedal (33) and housed in an axial hole (36) of a rod (37) securely fixed to the pistons so as to rest on the rear surface of the hole; the device also comprises a flow control valve (38) adapted to supply pressurized oil to the first chamber (25) at a rate proportional to an electrical signal, proportional to the force exerted on the clutch pedal and generated by a sensor (53).</p> |
