  • the invention relates to a method for controlling an elevator brake with a housing and an axially movable on a path between a braking position and a starting position operatively connected to at least one tractor unit brake unit, which brake unit is moved at least by means of a first spring force of at least one brake spring.
  • Elevator brakes must respond quickly on the one hand in an emergency and shut down the elevator car and the counterweight immediately, on the other hand, the elevator brakes must work as quietly as possible, so that the resulting noise in response to the elevator brake in the adjoining the elevator system rooms do not interfere.
  • Known elevator brakes have at least one brake force generating spring or brake spring, wherein an electromagnetic device operates with at least one electromagnetic coil against the spring force while holding the brake, inter alia, in a starting position. When the voltage on the coil is turned off, the magnetic field collapses and the one brake unit of the elevator brake presses due to the spring force of at least one brake spring against, for example, a brake disc, elevator rail, etc.

To do this, the elevator brake must be released. However, if there is no power supply available to the elevator system, the elevator brake can not be released without the subsequent crash of the elevator car. In order to prevent a crash of the elevator car, the elevator brake must be controllable, so that the elevator car can be moved safely in an emergency, for example, to an evacuation floor.
  • the elevator brake is adjustable, for example for gentler braking.

  • a core of the invention is that for controlling or regulating an elevator brake by means of a stroke generating lifting unit on a train unit of a brake unit, a movement in the axial direction against a first spring force of at least one brake spring is generated, wherein by means of a second spring force through the stroke the lifting unit tensioned compensating spring, the first spring force of the at least one brake spring is reduced.
  • the elevator brake has at least one housing and a brake unit movable in the axial direction on a path between a braking position and a starting position. Furthermore, the elevator brake has at least one brake spring which is in operative connection with the movable brake unit and which can be arranged in the housing.

  • the actuator can also be integrated in the lifting unit.
  • a manually operated lever, a motor spindle unit, a spindle unit, a motor, a hydraulic unit, a solenoid, etc. may be used as at least one actuator.
  • the at least one actuator can be controlled or regulated via a control unit connected to the at least one actuator.
  • the stroke of the lifting unit is controlled or controlled via the at least one actuator by means of the control unit.
