Oil management system for dual clutch transmissions

摘要

The present invention provides an improved fluid management system for dual and other multiple clutch assemblies having fluid-operated pistons and fluid operated balance chambers (68,70) offsetting the undesired pressures exerted by fluids within the piston chamber induced by centrifugal forces. Each balance chamber is in fluid communication with a fluid supply which is disposed to provide a gravity assisted flow to the balance chamber. The system provides an arrangement of fluid supply channels and supply openings capable of maintaining desired fluid levels in the balance chambers under low, otherwise insufficient, flow rate conditions. In another aspect, the system provides a reservoir for the balance chambers under conditions where the fluid flow is stopped or interrupted.
