20110079485 | NON-ROTATING CLUTCH AND METHOD OF INSTALLING SAME - A hybrid transmission includes a transmission housing and a motor/generator stator configured to be attached to the transmission housing. A clutch housing is configured to be attached to the motor/generator stator, such that the clutch housing is not directly attached to the transmission housing but is statically fixed. An axis of rotation defines a coordinate system having axial, radial, and clocking rotations. A first piloting feature may be formed on the clutch housing and a second piloting feature on the transmission housing. The first and second piloting features cooperate to axially and radially orient, but not attach, the clutch housing relative to the transmission housing. Third and fourth piloting features cooperate to orient the clocking rotation of the clutch housing. Stator bolts may permanently locate and attach the motor/generator stator to the transmission housing, and clutch bolts permanently locate and attach the clutch housing to the motor/generator stator. | 04-07-2011 |
20140360290 | CHAIN DRIVE POWER TAKE OFF FOR HYDRAULIC PUMP - A chain drive power take off assembly drives a hydraulic fluid pump from a torque converter input of a motor vehicle. The assembly includes a first, chain drive sprocket which is coupled to and driven by a engine output/torque converter input member such as an engine crankshaft or transmission input member, a chain and a second, driven chain sprocket which is coupled to a stub shaft and which, in turn, is coupled to an input shaft of the hydraulic pump. The driven sprocket resides in a housing secured to the side of the transmission and the pump is secured to the housing with its input shaft and axis of rotation disposed offset from and parallel to the axis of rotation of the transmission and torque converter input member. | 12-11-2014 |
