    • A direct drive apparatus for an elevator wherein a movable part of the direct drive, particularly a linear motor, is connected with ark elevator car or counterweight for transmission of compression and tension in the travel direction by a tension/compression strut with settable damping properties. The tension/compression strut includes first and second rods which lie on a longitudinal axis of the strut and extend into opposite ends of a sleeve. First and second nuts are threadably received in the ends of the sleeve. First and second spring elements are positioned in the sleeve abutting the first and second nuts respectively. A central spring element is positioned between first and second spring plates which abut the first and second spring elements respectively. Each rod extends through the respective nut, spring element and spring plate into the central spring element and is attached the respective spring plate to optimize the oscillation and body sound insulation.
    • 一种用于电梯的直接驱动装置,其中直接驱动装置的可动部分,特别是线性电动机与方舟电梯轿厢或配重相连,用于通过具有可设定的阻尼特性的张力/压缩支柱在行进方向上传递压缩和张力。 张力/压缩支柱包括位于支柱的纵向轴线上并延伸到套筒的相对端部的第一和第二杆。 第一和第二螺母可螺纹地容纳在套筒的端部。 第一和第二弹簧元件位于套筒中,分别与第一和第二螺母邻接。 中心弹簧元件位于分别抵靠第一和第二弹簧元件的第一和第二弹簧板之间。 每个杆通过相应的螺母,弹簧元件和弹簧板延伸到中心弹簧元件中并且附接到相应的弹簧板以优化振动和身体隔音。
