    • A housing mounts an input shaft with a clutch flange thereon, and an output shaft with an annular friction member thereon to divide the housing clutch chamber into two separate operating chambers. A brake ring has a first friction face facing the friction lining of the friction member while the friction member has a second friction lining facing the clutch flange. The friction member is axially displaceable a limited amounted by a compressible fluid for controlling the movement of the friction linings axially between the linings and into engagement with one of the brake member and the clutch flange. Each of the clutch flange and the brake ring has an annular groove concentric to the coextensive axes of the shafts that opens to the axially adjacent friction lining. The grooves serve to have granular material of the abradable material of the linings, if the linings are made of such material, accumulated therein and have the ribs of the linings that are formed by the abrasion of the linings extend axially thereinto to form a slight throttle gap.
    • 壳体在其上安装有离合器凸缘的输入轴,以及在其上具有环形摩擦构件的输出轴,以将壳体离合器室分成两个单独的操作室。 制动环具有面向摩擦构件的摩擦衬里的第一摩擦面,而摩擦构件具有面向离合器凸缘的第二摩擦衬垫。 摩擦构件可轴向移动,由可压缩流体限制,用于控制摩擦衬里在衬套之间轴向移动并与制动构件和离合器凸缘中的一个接合。 离合器法兰和制动环中的每一个具有与轴的共同延伸轴线同心的环形槽,其向轴向相邻的摩擦衬里开口。 如果内衬由这种材料制成,则凹槽用于具有衬里的可磨损材料的颗粒材料,并且其中衬垫的磨损通过轴向的磨损而形成,从而形成轻微的节气门 间隙。
