Title
(EN) BRAKE CONDITION MONITORING
(FR) SURVEILLANCE DE L'ÉTAT D'UN FREIN
Abstract
(EN) A brake (104) is operationally coupled by gear engagement to an axle (106) of a device, whereby turning on the brake (104) prevents the axle (106) from rotating. Monitoring condition of the brake (104) comprises driving the axle (106) of the device in a first rotation direction (204) when the brake (104) has been turned on. The axle (106) of the device is driven in a second rotation direction (208) when the brake (104) has been turned on. A first position angle (206) of the axle (106) of the device, which follows from driving the axle (106) of the device in the first rotation direction (204), is measured. A second position angle (210) of the axle (106) of the device, which follows from driving the axle (106) of the device in the second rotation direction (208), is measured. A clearance of the gear engagement of the brake (104) is determined (212) on the basis of a difference of the first (206) and the second (210) position angles.
(FR) Un frein (104) est fonctionnellement couplé par engrènement à un essieu (106) d'un dispositif de telle sorte que l'activation du frein (104) empêche la rotation de l'essieu (106). Une surveillance de l'état du frein (104) comprend les étapes consistant à : entraîner l'essieu (106) du dispositif dans un premier sens de rotation (204) lorsque le frein (104) a été activé ; entraîner l'essieu (106) du dispositif dans un second sens de rotation (208) lorsque le frein (104) a été activé ; mesurer un premier angle de position (206) de l'essieu (106) du dispositif qui résulte de l'entraînement de l'essieu (106) du dispositif dans le premier sens de rotation (204) ; mesurer un second angle de position (210) de l'essieu (106) du dispositif qui résulte de l'entraînement de l'essieu (106) du dispositif dans le second sens de rotation (208) ; et déterminer (212) un jeu de l'engrènement du frein (104) sur la base d'une différence des premier (206) et second (210) angles de position.
