Abstract
To reduce the attainable actuation times of an electrically actuated friction brake and simultaneously keep the friction brake inexpensive, an electrically actuated friction brake with a brake pad (3) actuated by an actuation device (10) is proposed, wherein for braking the actuation device (10) is driven by a spring and is held open by an electrical actuator (12), so that the spring actuates the friction brake (1) in case of a power loss, wherein a first transmission element (5), that is connected to the brake pad (3), and a second transmission element (8) with an elevation curve (17) are provided and a coupling element (15) is provided on the first transmission element (5), wherein a follower element (14) is arranged on the coupling element (15) that follows the elevation curve (17) under the action of the spring for actuating the first transmission element (5).
