Title
(EN) ELEVATOR BRAKE ACTUATOR HAVING A SHAPE-CHANGING MATERIAL FOR BRAKE CONTROL
(FR) ACTIONNEUR DE FREIN D’ASCENSEUR À MATERIAU À CHANGEMENT DE FORME POUR COMMANDER LE FREIN
Abstract
(EN)
An elevator machine (10) includes a motor (12) that rotationally drives a machine shaft (14). An elevator machine brake (20) applies braking force to a disk (22) that is coupled to the machine shaft (14) to slow or stop the rotation of the machine shaft (14). In one example, the elevator machine brake (20) includes a bias member (38) that applies a bias force to a caliper arrangement (32) to provide a braking force on the disk (22). A brake actuator (48) having a shape-changing material moves against the bias force to control engagement between the caliper arrangement (32) and the disk (22). A controller (26) selectively varies the braking force applied to the disk (22) by controlling an electric input to the shape-changing material of the brake actuator (48).
(FR)
La présente invention concerne un ascenseur (10) comprenant un moteur (12) entraînant en rotation une gaine d’ascenseur (14). Un frein d’ascenseur (20) applique une force de freinage à un disque (22) couplé à la gaine d’ascenseur (14) pour ralentir ou stopper la rotation de la gaine d’ascenseur (14). Dans un exemple, le frein d’ascenseur (20) comprend un élément de polarisation (38) appliquant une force de polarisation à un agencement d’étrier (32) pour appliquer une force de freinage sur le disque (22). Un actionneur de frein (48) fabriqué à partir d’un matériau à changement de forme se déplace à l’encontre de la force de polarisation pour commander la mise en prise entre l’agencement d’étrier (32) et le disque (22). Un dispositif de commande (26) fait varier de façon sélective la force de freinage appliquée au disque (22) en commandant l’entrée électrique en direction du matériau à changement de forme de l’actionneur de frein (48).
