Abstract
A hydraulic clutch assembly includes a housing defining an internal cavity, a shaft, a clutch pack, a piston and a cylinder. The shaft extends within the internal cavity along a rotation axis for a rotatable member. The clutch pack includes interleaved plates and discs which are configured to rotationally couple the rotatable member to the shaft. The piston may be disposed within the internal cavity of the housing. The piston includes a first piston region and a second piston region. The first piston region is configured to engage the clutch pack while the second piston region is spaced radially from the first piston region. The piston may be arranged within the housing to define a first pressure chamber between the piston and the housing. The cylinder may be disposed within the internal cavity of the housing and may include a hollow interior for receiving the second piston region. The second piston region and the cylinder may define a second pressure chamber.
