Two piece clutch assembly having twist lock joint

摘要

A clutch assembly adapted to be fixed to the casing of a transmission includes a clutch housing having a clutch subassembly supported therein and a piston housing having a piston subassembly supported therein. The clutch housing and the piston housing are disposed in abutting relation relative to one another such that the piston subassembly is moveable within the piston housing to actuate the clutch subassembly in the clutch housing. At least one of the housings includes at least one anti-rotation lug mounted thereon and adapted to be received in a corresponding recess in the casing of the transmission. The anti-rotation lug includes an overlapping portion which overlays the other of the housings when they are disposed in abutting relation relative to one another. The anti-rotation lug also includes a slot. The other of the housings includes at least one tab extending therefrom and corresponds to the slot. The tab is received in the slot to lock the clutch housing and the piston housing together prior to installing the assembly in the transmission.
