Abstract
To reduce the attainable actuation times of an electrically actuated friction brake and simultaneously keep the friction brake inexpensive, a second transmission element (8) with an elevation curve (17) is proposed in which a coupling element (15) is provided on a first transmission element (5), and on the coupling element (15) there is arranged a follower element (14) which follows the elevation curve (17) under the action of the electric actuator (12) for the actuation of the first transmission element (5).
Claims14
An electrically actuated friction brake comprising:
- a brake pad that exerts a pad pressing force during brake action;
- an actuation device actuating the brake pad;
- an electric actuator driving the actuation device;
- a first transmission element connected to the brake pad and comprising a coupling element;
- said actuation device being configured to rotate the first transmission element about a rotation angle during the brake action, whereby the pad pressing force results from the first transmission element receiving an input torque that depends on the rotation angle of the first transmission element;
- a second transmission element having an elevation curve and being rotated by the electric actuator;
- a follower element arranged on the coupling element and being configured to follow the elevation curve under action of the electric actuator when the electric actuator rotates the second transmission element;
- and
- a lever having a first end rotatably coupled to the coupling element and a second end coupled to the first transmission element,
- wherein the second transmission element provides the input torque for the first transmission element.
