LOW POWER HYDRAULIC CLUTCH ACTUATION SYSTEMS

摘要

A torque transfer mechanism for controlling the magnitude of a clutch engagement force exerted on a clutch pack that is operably disposed between a first rotary member and a second rotary member includes a hydraulic clutch actuation system. The hydraulic clutch actuation system includes an electric motor drivingly coupled to a pump. The pump supplies pressurized fluid to an accumulator. The pressurized fluid within the accumulator is selectively supplied to a piston to provide a clutch engagement force.
