Disclosed is a brake assembly (200) for an elevator system, having: a housing (210) defining a housing cavity (2145), a housing forward end with a forward end opening (2150) into the housing cavity, and a housing aft end; a first magnet (2210) disposed in the housing cavity, near the forward end opening; a second magnet (2230) disposed in the housing cavity, between the first magnet and the housing aft end, and wherein the second magnet is configured to: reduce attraction between itself and the first magnet, whereby the first magnet moves at least partially through the forward end opening to engage a guide rail (109) that is metallic, thereby preventing vertical movement of the first magnet of the brake assembly, when magnetically connected to the rail, relative to the housing; and attract the first magnet to draw the first magnet into the housing cavity.

    本发明公开了一种用于电梯系统的制动器组件,其具有:壳体,其限定壳体腔、具有进入壳体腔中的前端开口的壳体前端以及壳体后端;第一磁体,其在壳体腔中设置于前端开口附近;第二磁体,其在壳体腔中设置于第一磁体与壳体后端之间,并且其中,第二磁体配置成:减小本身与第一磁体之间的吸引力,由此第一磁体当相对于壳体磁性地连接到轨道时,至少部分地移动通过前端开口,以接合金属的引导轨道,由此防止制动器组件的第一磁体竖直移动;并且吸引第一磁体,以将第一磁体吸到壳体腔中。
