Abstract
A multiple, interleaved friction plate clutch has a clutch pack including a plurality of externally toothed clutch plates and a plurality of internally toothed clutch plates which are interleaved with said externally toothed clutch plates. Hydraulically actuated means are provided for clamping said interleaved plates together to provide a releasable driving connection, whereby said plates may be shifted between a clutch clamp-up position and a clutch released position in which said plates are separated from one another and have relative rotation therebetween. A plurality of axially extending rods are circumferentially spaced around and located adjacent the outer periphery of the externally toothed clutch plates, and a plurality of axially extending rods are circumferentially spaced around and located adjacent the inner periphery of the internally toothed clutch plates. Sets of rods have a connection with their respective clutch plate, so that when the clutch is released, the rods hold their respective plates normal to the axis of rotation of the clutch and prevent the plates from wobbling.
