Electrohydraulic actuation device i.e. actuator, for actuation of dry clutch of automated gearbox of car, has springs pushed back towards housing such that springs are relaxed at time of passage of output element in front of ramps
The device i.e. actuator (1), has an electrical motor (10) movable in a housing (21), and an output element (50) for controlling filling and draining of a jack transmitting chamber (31). A movement of the motor is transmitted to the output element via a mechanical reduction gear (40) using a mechanical energy accumulator (60). Springs (63) are slidingly placed in sleeves (61a, 61b) and pushed back relative to each other towards the housing such that the springs are relaxed at a time of passage of the output element in front of widening ramps (21a) of the housing.
