Abstract
With this safety disc brake all regulatory safety requirements can be fulfilled with a constructional expenditure approximately like that expended for a simple construction of brake. Fulfillment of the essential safety requirements is attained by providing two partial systems which mechanically operate completely independent of one another and comprise two identical brake levers each provided with a respective separate compression spring braced at a common central impact member fixedly connected with a machine part. As a further feature for fulfilling the safety requirements both of the partial systems are devoid of any mutual mechanical penetrations and overlapping. Opening or release of the brake is accomplished electromagnetically with a pot magnet fixedly secured to one brake lever and an armature plate likewise fixedly secured to the other brake lever. The attachments for connection of the pot magnet and the armature plate to the brake levers are adjustable, so that the armature plate is always attracted for parallel movement by the pot magnet and thus there is not produced impact noise.
