Abstract:
A dual clutch actuation assembly includes a housing, an annular central piston, a plurality of satellite pistons, and an annular apply member. The housing includes an inner cylindrical wall, an outer cylindrical wall, and a plurality of satellite cylindrical walls. The inner and outer walls define an inner piston annulus and the satellite walls define a plurality of satellite piston bores. Each of the satellite walls is disposed at least partially radially outward of the outer wall. The central piston is disposed in the inner piston annulus and is in sliding engagement with the inner and outer walls of the housing. The satellite pistons are disposed in the satellite piston bores and are in sliding engagement with the satellite walls of the housing. The apply member is axially engaged with each of the satellite pistons and includes an annular plate portion disposed radially outward of the outer cylindrical wall of the housing.
