ELECTRO-MECHANICAL ACTUATOR ASSEMBLY FOR ACTUATING A BRAKE ACTUATOR, BRAKE ASSEMBLY AND VEHICLE

Electro-mechanical actuator assembly (1) for actuating a brake actuator (20), comprising: an actuation mechanism (3, 6) configured to convert a rotational driving movement into a translational driven movement in a direction of a first longitudinal axis (L1), and a pushing member (4, 4', 4") operatively coupled to the actuation mechanism (3, 6) to receive and transfer the translational driven movement at least in the direction of the first longitudinal axis (L1), wherein the actuation mechanism (3, 6) is a spindle-spindle nut mechanism, wherein a spindle nut (6) of the actuation mechanism (3, 6) is rotationally supported about the first longitudinal axis (L1) while being axially fixed, and wherein a spindle (3) of the actuation mechanism (3, 6) is configured to be axially moveable with respect to the first longitudinal axis (L1) while being rotationally fixed.
