ABSTRACT:
A clutch or brake assembly in which a hub and reaction member are, in the operative condition of the clutch or brake, coupled together through coupling discs, has one or a plurality of first coupling discs restrained against rotation relative to the reaction member and displaceable relatively thereto axially of the hub, so that it or they can be moved into engagement with one or more second coupling discs, e.g. friction discs, mounted for rotation with the hub to render the clutch or brake operative. The or each first coupling disc is located axially relatively to the reaction member in the inoperative condition of the clutch or brake by a set of spring members mounted directly on the coupling disc through a frictional gripping engagement. Where a plurality of the first coupling discs and a corresponding number of spring sets are used, the spring members of one set interconnect with the spring members of the adjacent set. This can be achieved by providing holes in each of the first coupling discs, in each of which holes a loop portion of a spring member frictionally engages, the loop portion extending through and beyond the hole in which it is located to interconnect with a spring member of the adjacent set.
