Abstract:
A normally closed automotive clutch with hydraulic drive and having: a stack of driven and driving plates, which are mounted so as to rotate around a rotation axis; a pressure ring, which is mechanically coupled to the stack of plates and can axially slide so as to axially compress the stack of plates; at least one elastic closing element, which presses the pressure ring; a hydraulic actuator comprising an inner actuation chamber, which is suited to be filled with a fluid under pressure so as to generate an opening thrust, and a sliding piston, which is coupled to the inner actuation chamber and is mechanically connected to the pressure ring; and a box, which is provided with a lateral lid and houses the stack of plates, the pressure ring, the elastic closing element, and the hydraulic actuator.
