Kompaktes mehrstufiges Schaltgetriebe für Kraftfahrzeuge.

摘要

A transaxle for an automotive vehicle driveline having an internal combustion engine, a hydrokinetic torque converter (10) mounted on the axis of the crankshaft of the engine, multiple ratio gearing (118,160) mounted on an output shaft axis (86) located in parallel relationship with respect to the engine crankshaft axis, and a torque transfer drive (14,68,70,78,86) comprising a dual torque flow path between the turbine of the torque converter and the torque input elements of the gearing including clutch and brake structure (96,138,144,106,178,170) for effecting ratio changes in the gearing, the torque converter, the torque transfer gearing and the multiple ratio gearing being packaged in a common assembly with maximum space economy whereby the clutch and brake structure is adapted to select one torque flow path or the other through the transfer drive as well as to control the torque flow pattern through the multiple ratio gearing and whereby the N/V design parameter for the transaxle may be chosen to effect optimum driveline efficiencies for the engine and for the transaxle as well as the optimum gradeability for the vehicle.
