Abstract
A disk brake, preferably for use in connection with industrial machinery, has a pair of braking levers which carry at one end brake shoes located on opposite sides of the disk. The braking levers are operatively interconnected at the end opposite the brake shoes, and emergency on/off control means are provided which includes gripping means urging one of the braking levers into braking contact with the disk; electromagnetic release means are provided operable to oppose the action of the gripping means. Progressively acting control means in the form of an electromagnet are also provided adapted to act on one of the braking levers.
Claims11
A disk brake, particularly for industrial purposes, comprising a frame, a rotatable disk for connection to the member which is to be braked, two brake shoes disposed respectively one on each side of the disk, braking levers to which the said shoes are pivotally connected, and which braking levers are operatively pivotally interconnected, an on/off control means acting on the said braking levers and comprising resilient gripping means adapted normally to urge one of the said brake levers in a direction corresponding to the gripping of the disk, electromagnetic release means operable to oppose the action of the said gripping means, and progressively acting control means adapted to act as one of the said braking levers in a direction corresponding to the gripping of the disk, the said progressively acting control means comprising an electromagnet whose movable element is adapted to act on the associated braking lever.
