HYDRAULISCHE STEUERVORRICHTUNG FUER EIN SELBSTTAETIG SCHALTENDES HYDRODYNAMISCH- MECHANISCHES VERBUNDGETRIEBE VON KRAFTFAHRZEUGEN

摘要

A multiple ratio power transmission mechanism having a gear system and a hydrokinetic unit with a lockup clutch that responds to pressure in the hydrokinetic unit to establish a mechanical torque delivery path around the hydrokinetic unit and a valve system for engaging and disengaging the clutch and for controlling clutch capacity by modulating the clutch pressure and by controlling the direction of fluid flow through the hydrokinetic unit.
