FRICTION BRAKE HAVING AN ACTUATOR UNIT THAT ACTS PERPENDICULARLY TO THE BRAKE APPLICATION DIRECTION

摘要

The invention relates to a friction brake (1), in particular for elevators, comprising at least two pivotably arranged brake levers (2), which each have a brake lining (6) and are arranged opposite each other in the form of a pair of brake tongs. An actuator (5) is provided for actuating the friction brake (1). In order to avoid uneven loading of the brake levers (2) lying opposite each other, the actuator (5) is designed in such a way that the force (FA) exerted by the actuator (5) acts substantially perpendicularly to a brake application force (Fz) exerted by the brake levers (5). Furthermore, a spreading mechanism (9, 26) is provided, by means of which the brake application force (Fz) can be regulated by the force (FA) exerted by the actuator.
