Abstract
A caliper brake for braking a moving component, including a housing and two brake shoes, which are movable within the housing toward the component to be braked, and a bearing part, which is movable within the housing by an actuator. The brake shoes each have a wedge surface on a side facing away from the component to be braked, by which a braking force acting on the bearing part is transmitted to the brake shoes with deflection and force multiplication. For higher braking forces using a spring-actuated brake, and to reduce the effects of spring travel on the braking force, the bearing part has offset bearing locations against which the wedge surfaces of each brake shoe bear. The wedge surfaces each have, in the region of the bearing locations, a step which is overcome during a closing movement of the brake shoes before they engage the component to be braked.
