    • A torsion damping device includes a support wheel, having first fastening screws for attaching it to a driving shaft, a damper plate, and peripheral springs acting between the support plate and the damper plate. The damper plate, carrying a pair of guide rings, constitutes, together with the springs and a drive plate, a torsion damper which is contained in a sealed housing, the components of which are secured together by second fastening screws.The inner periphery of the sealed housing has a diameter greater than that of the pitch circle on which the holes for the first fastening screws are arranged in the support wheel, while the damper plate emerges radially from the housing, in a manner which provides axial location but circumferential sliding movement of the damper plate in the housing while preserving sealing. The second fastening screws of the housing are separate from the first fastening screws and their holes in the support wheel, while one of the components defining the housing carries a cover for urging the torsion damper into rotation, the latter being conformed so as to cooperate therewith.
    • 扭转阻尼装置包括支撑轮,其具有用于将其附接到驱动轴的第一紧固螺钉,阻尼板和作用在支撑板和阻尼板之间的周向弹簧。 承载一对引导环的阻尼板与弹簧和驱动板一起构成一个扭转阻尼器,该扭转阻尼器容纳在密封的壳体中,其中的阻尼板的部件通过第二紧固螺钉固定在一起。 密封壳体的内周的直径大于节圆的直径,第一紧固螺钉的孔布置在支撑轮中,而阻尼板从壳体径向地露出,以提供轴向位置 但是在保持密封的同时,阻尼板在壳体中周向滑动。 壳体的第二紧固螺钉与支撑轮中的第一紧固螺钉及其孔分离,而限定壳体的部件中的一个部件承载用于推动扭转阻尼器转动的盖,后者适于与其配合 。
