ABSTRACT:
A system and method for supplying cooling fluid for frictional elements, for example multiple disc clutches and multiple disc brakes, in automatic transmissions. The cooling fluid flows through the multiple disc clutch or brake in a predefined manner radially inward or outward, whereby a defined flow through the clutch or brake packet is ensured through a defined pressure difference in the cooling fluid between the cooling fluid supply and the discharge of the cooling fluid. A preferred embodiment of device for supplying the cooling fluid is designed as a ring-shaped channel that partially or fully encloses the clutch or the brake.
