摘要： A transmission includes first and second clutch members rotatable about the same axis. An axial groove is formed in one of the members to distribute lubricating fluid to the other member. Preferably, clutch plates with radial grooves extend between the clutch members. Fluid flows from the axial groove through the radial groove and across faces of the clutch plates to separate the plates during disengagement in order to minimize spin losses.

摘要： A method and apparatus for efficiently cooling and lubricating rotating components in a hybrid transmission is provided. By efficiently managing cooling flow to and between the rotating elements, flow requirements and associated pumping requirements within the drive unit are minimized. In addition, by providing a method for placing the fluid directly on the required components, spin losses associated with component contact with stray oil are reduced. Combined, the reduction in pumping and spin losses create a more efficient drive unit and an overall more efficient hybrid drive system which directly leads to higher fuel economy.

摘要： An assembly and method is provided for reducing clutch wear due to centrifugal apply pressure within a clutch-apply cavity. The assembly comprises a rotatable clutch housing, a clutch-apply piston disposed within a clutch-apply cavity, and a balance piston. The balance and apply pistons define a balance cavity including a liquid fill channel and a dedicated air exhaust channel having a control radius configured to at least partially offset or compensate for the centrifugal apply force generated within the clutch-apply cavity when the clutch assembly rotates. The method includes configuring the balance cavity with an exhaust channel for exhausting fluid, and providing the exhaust channel with a control radius determined by the innermost radius of rotating fluid within the balance cavity as measured with respect to the centerline of rotation of the clutch assembly, the control radius being suitable for exhausting any excess of centrifugal balance force over centrifugal apply force.

摘要： An electrically variable transmission (EVT) selectively establishes various EVT modes and a neutral mode. The EVT includes a source of pressurized fluid, fluid-actuated clutches, various solenoid-actuated valves including trim valves and blocking valves adapted to control a flow of pressurized fluid to the clutches to establish the transmission operating modes, and an electronic control unit (ECU). The ECU actuates different combinations of the solenoid-actuated valves to establish the different transmission modes. The solenoid-actuated valves are configured in such a manner as to provide the EVT with one or more default operating modes in the event the ECU temporarily loses electrical power. Depending on the particular configuration, the default modes can be the neutral mode alone, or the neutral mode combined with one or more of the EVT modes, with the EVT modes enabled by providing one or both of the blocking valves with a latching feature.
