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 pivotally mounted brake levers (2), which each have a brake lining (6) and are arranged opposite each other in the form of a brake caliper. An actuator (5) is provided for actuating the friction brake (1). In order to avoid uneven loading of the opposing brake levers (2), 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.

1. A friction brake (1), in particular for elevators, comprising at least two brake levers (2) that each have a brake lining (6) and are arranged opposite each other in the form of a caliper, wherein at least one brake lever (2) is pivotally mounted, and an actuator (5) for actuating the brake levers (2), which is configured in such a way that the force (FA) exerted by the actuator (5) acts substantially perpendicular to a clamping force (FZ) exerted by the brake levers (2), and a spreading mechanism (9, 26), which can be acted on by the actuator (5) in order to regulate the clamping force (FZ), wherein the spreading mechanism (9, 26) comprises a roller unit (9) that is controlled by an actuator (5), said roller unit having a first roller (21) that rolls on a first surface (10) provided on the first brake lever (2), and a second roller (22) that rolls on a second surface (48) provided on the second brake lever (2), wherein the rollers (21, 22) rotate around the same axis of rotation.
