ABSTRACT:
A hydrokinetic transmission mechanism for an automotive vehicle driveline including a hydrokinetic torque converter and multiple ratio planetary gearing in combination with a torque splitter gear unit located within the converter housing, the multiple ratio gearing having two separate torque input shafts and the splitter unit being adapted to distribute torque to each of the input shafts, one torque delivery path being fully mechanical and the other being hydrokinetic, the torque splitter unit including a simple planetary gear unit with a pocketed carrier, the planetary gear elements of the torque splitter gear unit being journalled on their peripheries in the carrier thus eliminating the need for a separate torque splitter pinion shafts and bearings.
