Actuator assembly for a positively locking, switchable clutch or a brake, and a positively locking, switchable clutch or brake for a motor vehicle drive train

An actuator assembly for a positively locking, switchable clutch or a brake, comprising:

• a shaft that can be rotated with respect to a rotational axis,
• an actuator slide for the actuation of the positively locking, switchable clutch or the brake, the actuator slide being connected to the shaft for conjoint rotation and configured to be moved relative to the shaft in the axial direction between a first position and a second position, and
• an actuator which is at least partially stationary and moves the actuator slide between the first position and the second position, wherein
• the actuator comprises a coil which is stationary and generates a magnetic field in the energized state, in which the actuator slide can be moved out of the first position into the second position or vice versa,
• the coil is not energized in the first and second position, and
• the actuator fixes the actuator slide in the first position and the second position, and
• the actuator comprises a spring that extends in the axial direction and fixes the actuator slide in the first or the second position, the spring being always connected to the actuator slide and to a supporting section of the actuator.
