Abstract
Holding brake for a traction sheave elevator, comprising a brake body (1), a movable frame (2) movably mounted in the brake body, a brake pad (3) attached to the movable frame, a pulling element (4) mounted on the brake body for pulling the movable frame toward the brake body and a compressing element (5) mounted between the brake body and the movable frame and serving to move the movable frame away from the brake body and press the brake pad attached to the movable frame against the brake surface (6). A gap (9) is provided between the movable frame surface (7) oriented in the direction of motion of the movable frame (2) and a counter surface (8) oriented in a corresponding direction, in which gap (9) is fitted a damping element (10) which is in contact with both surfaces to damp the motion of the movable frame.
