Hub clutch assembly

摘要

A power transmission assembly includes a first rotary housing and a second rotary housing disposed within the first housing. A piston housing is disposed between the first and second housing and does not rotate. A clutch plate stack is disposed adjacent to the piston assembly and is engageable to prevent relative rotation of the first and second housings with respect to one another. The rotary housings are supported by a bearing between the housings at one end, and by a series of bearings between the housings and the piston assembly at an opposite end. The arrangement enables the assembly to be supported as an overhung load, while actuating fluid is applied to the piston assembly via a non-rotating manifold.
