ABSTRACT:
A hydraulically actuated clutch includes a pair of hydraulic cylinder housings formed as blocks bolted to the clutch housing. In a most Preferred embodiment, the hydraulic cylinder housing extends into an opening in tie side wall of the outer clutch housing and is bolted at an outer location to the transmission bell housing. A fluid connection is made at an outer surface such that an assembler need not reach into the transmission bell housing to make the fluid connections. The hydraulic cylinder housing preferably has a machined piston bore, and fluid passages communicating the piston bore to the connection at the outer location on the hydraulic cylinder housing. In a second embodiment, a hydraulic cylinder housing also includes a block having a machined piston bore and fluid passage, however the block is bolted to an internal surface in the outer clutch housing. The improved hydraulic cylinder housings simplify assembly of the hydraulic cylinder housings to the clutch, and also simplify the connection of the hydraulic fluid.
