Torque converter slipping clutch and control

摘要

A torque converter and slipping clutch assembly has an adjustable apply orifice which establishes the torque split between the torque converter and the clutch. The orifice controls fluid communication between clutch engagement and disengagement chambers to establish the effective clutch apply pressure. A viscous damper is connected to the clutch and torque converter in parallel with the orifice to prevent rapid adjustment of the orifice during transient torque impulses.
