Screw pump aggregate for automatic transmission of motor car, has pump formed such that pump produces cooling stream in operating mode, power stream in another operating mode, both cooling stream and power stream in third operating mode

摘要

The aggregate (1) has two partial gear boxes with a clutch to connect the partial gear boxes with a drive. A screw pump (2) is formed such that the pump produces a cooling stream in an operating mode for the clutch and a power stream in another operating mode for regulating units of a dual clutch transmission (7). The pump produces both the cooling stream and the power stream in a third operating mode. A control device (29) controls the pump, which is selectively operated in the operating modes. The pump has an outlet (4) connected with the clutch.
