A process for the cooling fluid feed system for multiple disk clutches and - brakes in automatic transmissions and device for cooling fluid feed system

摘要

A process for the cooling fluid feed system for multiple disk clutches and - brakes in automatic transmissions of a motor vehicle, wherein the cooling fluid the multiple-disc clutch and / or - brake (1) radially from the outside in the direction of the center of rotation or in the opposite direction, and whereby by means of a predefined pressure difference in the cooling fluid between the cooling fluid feed system and the discharge of the cooling fluid a defined flow through the coupling - or of the brake packet is ensured, characterized in that the pressure difference over a corresponding control for the cooling fluid volume current control is designed to be variable, wherein the dynamic pressure of the cooling fluid as a control signal for the cooling fluid volume control is used.
