ABSTRACT:
A plate locating apparatus for a multiple disc clutch provides a mechanism for axially locating a plurality of intermediate plates relative to the discs interleaved therebetween, and thus insures that the respective intermediate plates and discs will be separated whenever the clutch is disengaged, for example, during the idling of an associated vehicle. In a preferred embodiment, the apparatus is defined by an axially extending rod affixed to the clutch cover, the rod extending through concentrically aligned apertures in the intermediate plates. A plurality of cylindrical sleeves are piloted on the rod, each sleeve extending through the aperture of one intermediate plate. Each sleeve contains abutment means at opposite ends thereof which are disposed for contacting the respective sides of an associated intermediate plate. A one-way frictional gripping mechanism is provided on the internal bore of each sleeve to prevent movement of the sleeve in one direction along the rod, but to otherwise permit the sleeve to move along the rod in the opposite direction.
