Abstract
A controllable powertrain input module, placed between an input torque source and an automated ratio changing device, all of which is controlled by a powertrain control module (PCM) to optimize efficiency while satisfying an infinite number of input and output application scenarios.
Claims19
A controllable powertrain input module 100, comprising:
- a) a housing which is connected to an input torque source;
- b) a planetary gear set assembly;
- c) a multi-plate wet friction input clutch assembly splined to an internal diameter of the housing;
- d) an axially moveable hydraulic input clutch piston wherein the clutch piston applies specific controlled clamping force to the input clutch assembly and supplies specific cooling flow to at least one friction plate of the input clutch assembly via a first pressure volume;
- e) a multi-plate wet friction mode shift clutch assembly splined to the internal diameter of the housing;
- f) an axially moveable hydraulic mode shift clutch piston which applies specific controlled clamping force to the mode shift clutch assembly;
- g) a reaction plate disposed within the internal diameter of the housing wherein the reaction plate functionally interfaces with both the input clutch assembly and the mode shift clutch assembly;
- and
- h) a locking device configured to allow angular rotation of the planetary gear set assembly in one direction only.
