Abstract: A hydraulic control system for a multi-mode hybrid-type power transmission is provided, including an engine-driven main pump in fluid communication with a main regulator valve, and an electrically driven auxiliary pump in fluid communication with an auxiliary regulator valve. A first pressure control solenoid is configured to provide boost pressure to the main regulator valve and thereby boost output of the main pump. A second pressure control solenoid is configured to provide boost pressure to the auxiliary regulator valve and thereby boost output of the auxiliary pump. The distribution of boost pressure from the pressure control solenoids is selectively modified such that at least one of the flows of pressurized fluid from the pumps is equal to the current line pressure requirements of the transmission during engine auto-start and auto-stop, and transitions thereto. An improved method for regulating the hydraulic control system is also provided.

Abstract: Substrates prone to heat distortion may be coated with a coating composition containing chlorinated polyolefin-modified acrylic latex emulsion, polyurethane dispersion, non-gelling self-crosslinking acrylic emulsion, and glycol-based solvent. The coating composition contains sufficient non-gelling self-crosslinking acrylic emulsion and glycol-based solvent so that a 0.1 mm wet thickness layer of the coating composition will form a tack-free film when heated at 65° C. for fifteen minutes, and the glycol-based solvent is selected so that the coating composition is shelf stable.

Abstract: A servo valve for shifting a transmission between a park and out of park position includes a valve housing and a park servo. A first and second solenoid is disposed in the valve housing for transmitting a respective first or second signal to shift the transmission to the respective first or second state of operation. The park servo is fluidly connected to the transmission and is responsive to the first and second signals to shift the transmission to the respective positions. Fluid pressure within the valve housing moves a valve member therein to move a piston within the park servo to shift the transmission to the corresponding position. A third solenoid transmits a third signal in combination with the second signal to latch and hold the valve member in the corresponding position.

Abstract: 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.

Abstract: A rotating clutch operably disposed between two rotating components includes a hydraulic operator having a piston and, on one side of the piston, an apply chamber or cavity and, on the opposite side of the piston, a balance chamber or cavity. The apply chamber is selectively provided with pressurized hydraulic fluid to engage and release the clutch to couple and de-couple the two rotating components. The balance chamber is provided with a flow of pressurized hydraulic fluid from the transmission lubrication system that flows through the transmission main shaft and flow restricting passages to the balance chamber. An exhaust port downstream of the balance chamber releases excess hydraulic fluid flow. Thus, whether, the clutch is rotating or not, hydraulic pressure is maintained in the balance chamber and proper clutch operation is assured.
