<p>Safety disc brake for elevators having two subsystems, operating completely independently of one another mechanically, in the form of two identical brake levers (4) each with a separate compression spring (9, 10) supported against a common spring stop centre (2.3) which, for its part, is firmly connected to a machine part (1). The two subsystems do not have any mutual mechanical penetrations and overlaps. The lifting function of the brake is performed electromagnetically by means of a pot-shaped magnet (5), which is rigidly secured on one brake lever (4), and an armature plate (6), which is secured, likewise rigidly, on the other brake lever (4). The fixings of the pot-shaped magnet (5) and the armature plate (6) on the brake levers (4) are adjustable in order to ensure that the armature plate (6) is always attracted in completely parallel fashion by the pot-shaped magnet (5) and thus does not produce any impact noise. …<IMAGE>… </p> |
