HYDRAULIC CONTROLLER FOR AN AUTOMATIC TRANSMISSION OF A MOTOR VEHICLE |
摘要 |
A hydraulic controller for an automatic transmission of a motor vehicle includes at least one gear shift piston-cylinder unit having a gear shift piston for actuating a shifting element in the form of a multi-plate clutch, and a gear shift pressure chamber in which an actuating pressure may be built up by supplying operating fluid. The gear shift piston-cylinder unit has a centrifugal oil chamber that is separated from the gear shift pressure chamber by a gear shift piston. Operating fluid may be supplied to the centrifugal oil chamber via a centrifugal oil line supplied by a first supply line. The hydraulic controller has a second supply line for supplying operating fluid to the centrifugal oil line. The second supply line may be closed and opened by a centrifugal oil valve. |
