Latest Patents

Ewald Ast holds a patent for a "Method and device for coolant oil feeding to a multiple-disc shifting element of an automatic transmission." This innovative system and method are designed to supply cooling fluid for frictional elements, such as multiple disc clutches and multiple disc brakes, in automatic transmissions. The cooling fluid is directed to flow through the multiple disc clutch or brake in a predefined manner, either radially inward or outward. This design ensures a defined flow through the clutch or brake packet by maintaining a specific pressure difference in the cooling fluid between the supply and discharge points. A preferred embodiment of the device is a ring-shaped channel that partially or fully encloses the clutch or brake.
