Passive magnetic elevator car steadier

摘要

A device (22) for damping vibrations between a first component (16) and a second component (14) includes a receiving member (24) configured to be connected to the first component (16), a first permanent magnet (26) arranged inside the receiving member (24), a second permanent magnet (28) arranged inside the receiving member (24) in series with the first magnet (26), and an engaging member (30) slidably connected to the receiving member (24) and including a first end configured to engage the second component (14) and a second end inside the receiving member (24) adjacent the first magnet (26). The second magnet (28) includes a pole which repels a facing pole of the first magnet (26).

主权项

1. An elevator system, the system comprising:
a car; a car frame connected to the car; and at least six pairs permanent magnet dampers arranged to dampen movement of the car relative to the car frame, at least three of the pairs of the permanent magnet dampers positioned proximate a top of the car, and at least three of the pairs of the permanent magnet dampers positioned proximate a bottom of the car, wherein each of the permanent magnet dampers comprises: a receiving member connected to one of the car or the car frame; an engaging member slidably connected to the receiving member at a first end, and configured to engage the other of the car or the car frame at a second end; a first permanent magnet arranged inside the receiving member; and a second permanent magnet slidably arranged inside the receiving member in series with the first magnet, the first permanent magnet and the second permanent magnet positioned within the receiving member such that a pole of the first permanent magnet is adjacent a similar pole of the second permanent magnet to form a repulsive force between the first permanent magnet and the second permanent magnet, and the second permanent magnet further positioned in the receiving member such that a dissimilar pole of the second magnet is located adjacent the first end of the engaging member; wherein the first end of the engaging member contacts the dissimilar pole of the second permanent magnet, and the repulsive force thereby biases the engaging member towards the other of the car or the car frame; and wherein each of the at least six pairs of permanent magnet dampers comprises a first permanent magnet damper configured to resist movement in a first direction and a second permanent magnet damper configured to resist movement in a second direction opposite the first direction.
