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.
