Electro-Mechanical Actuator Assembly for Actuating a Brake Actuator, Brake Assembly and Vehicle

An electro-mechanical actuator assembly for actuating a brake actuator includes an actuation mechanism configured to convert a rotational driving movement into a translational driven movement in a direction of a first longitudinal axis, and a pushing member operatively coupled to the actuation mechanism to receive and transfer the translational driven movement at least in the direction of the first longitudinal axis. The actuation mechanism is a spindle-spindle nut mechanism, wherein a spindle nut of the actuation mechanism is rotationally supported about the first longitudinal axis while being axially fixed, and wherein a spindle of the actuation mechanism is configured to be axially moveable with respect to the first longitudinal axis while being rotationally fixed.
