Abstract

An automatic transaxle for use in an automotive vehicle driveline including a compound planetary gearset, a hydrokinetic unit and a torque splitter gear unit that cooperate to define torque delivery paths from the vehicle engine to a driven shaft; the driven shaft being located between the hydrokinetic unit and the compound planetary gearing and the torque splitter gear unit being located within the housing for the hydrokinetic unit; and clutch-and-brake means for establishing and disestablishing each of the forward driving ratios and the reverse drive ratio, the clutch-and-brake means being arranged in a compact fashion within the housing for the compound planetary gearing to provide a minimum axial length of the assembly; the driven shaft being connected drivably to the vehicle traction wheels through a differential gearing mechanism; the hydrokinetic unit, the gearing and the differential mechanism being enclosed in a common cast housing.
