Abstract: This application relates to compounds of Formula (I): or pharmaceutically acceptable salts thereof, which are inhibitors of PI3K-? which are useful for the treatment of disorders such as autoimmune diseases, cancer, cardiovascular diseases, and neurodegenerative diseases.

Abstract: A drive assembly for a work vehicle includes an electric motor configured to rotate a driving shaft and a gear train configured to transmit torque between the driving shaft and a driven shaft. The drive assembly also includes a clutch member having an engaged position and a disengaged position. The clutch member is configured to allow torque transfer between the driving shaft and the driven shaft when in the engaged position. The clutch member is configured to prevent torque transfer between the driving shaft and the driven shaft when in the disengaged position. The clutch member is biased toward the disengaged position to prevent torque transfer in a direction from the driven shaft toward the driving shaft in an overspeed condition of the drive assembly.

Abstract: A clutch assembly configured to selectively engage and disengage a power source and a transmission includes an input member configured for coupling to the power source and an output member configured for coupling to the transmission. A clutch pack is engaged with the input member for co-rotation about an axis. A housing is engaged with the output member and with the clutch pack and is further configured to move in a first direction along the axis and in a second direction opposite to the first direction. The clutch assembly includes a cover and a ring member positioned along the axis from the cover such that the cover and the ring member define a movable chamber therebetween configured to receive a hydraulic fluid. The clutch pack is operable to decouple the input member from the output member in response to a pressure of the hydraulic fluid within the chamber.

Abstract: An oil seal arrangement includes a non-rotating oil ring and a rotating guide ring. A flexible oil seal is bonded to the oil ring and sealingly engages the guide ring to retain lube oil in a bearing chamber. A flexible lip seal and a spacer member rotate with the guide ring and slidably engage portions of the oil ring which are exposed to lube oil and spaced apart from the oil seal.
