    • An elevator system includes a roller (16) having a hardness that varies responsive to a magnetic field (20). The roller (16) rolls along a guide rail (28) to maintain a desired orientation of the elevator car (12). In one example, the roller (16) includes a membrane (30) defining a generally annular chamber (36) containing fluid (22) that changes viscosity responsive to changes in the magnetic field (20). The rollers (16) are associated with at least one magnetic field generator (18) that generates a magnetic field (20) of a selected strength. Varying the magnetic field varies the hardness of each roller (16) to control vibrations of the elevator car (12) to improve ride quality.
    • 电梯系统包括具有响应于磁场(20)变化的硬度的辊(16)。 滚轮(16)沿着导轨(28)滚动以保持电梯轿厢(12)的期望取向。 在一个示例中,辊(16)包括限定大体上环形的室(36)的膜(30),其包含响应于磁场(20)的变化改变粘度的流体(22)。 辊(16)与产生具有所选强度的磁场(20)的至少一个磁场发生器(18)相关联。 改变磁场改变每个辊(16)的硬度,以控制电梯轿厢(12)的振动,以改善乘坐质量。
