A screw actuator, particularly for a brake calliper, comprising a housing (1), a screw mechanism (4) with a screw (6) and a nut (5), one of which is rotatably supported with respect to the housing (1), a motor (7) which is drivingly connected to the screw mechanism (4), a mechanical locking device comprising a pawl member (41) and a rotatable member (42) connected to a rotatable component of the motor (7) and/or the screw mechanism (4), and a mechanical or electromechanical control mechanism for displacing the pawl member (41) between a locking position and a free position. A gear reduction mechanism (20) is provided, one of the gear wheels (42) thereof carries teeth (45) for engaging with the pawl member (41).
A screw actuator, comprising
A screw actuator according to claim 2, wherein the pawl member (41) and the drive member (55) are freely rotatable with respect to one another within a limited arc of rotation defined by an end stop (63, 65), such that the pawl member (41) is rotated together with the drive member (55) after the pawl member (41) has been displaced from the drive member (55) and has been brought in the locking position in which it is rotationally fixed to the rotatable component of the motor (7).
