摘要： An actuator that causes a mode clutch to shift between an engaged position and a disengaged position is provided. The actuator comprises a motor having an output. A shift cam is caused to rotate based on the output of the motor. The shift cam has a cam profile surface. A cam follower rides along the cam profile surface upon rotation of the shift cam. Movement of the cam follower causes movement of a mode fork resulting in the mode clutch shifting between the engaged and disengaged positions. A sensor outputs a voltage to a controller based on a physical location of the cam follower. The controller activates the motor based on the voltage.

摘要： A powertrain with a disconnecting rear drive axle generally includes a prime mover including an output that rotates about a rotational axis. A transmission includes an output that rotates about a rotational axis. The rotational axes of the outputs are substantially parallel to a longitudinal axis of the powertrain. A front driveline is operable to direct rotary power from the prime mover to front vehicle wheels. A rear driveline includes a propeller shaft that provides rotary power to a first shaft member and a second shaft member through a pinion and a ring gear. The first shaft member and the second shaft are operable to connect to rear vehicle wheels. A power switching mechanism has an engaged condition and a disengaged condition. The power switching mechanism is operable to direct the rotary power from the transmission to the rear driveline in the engaged condition. A torque transfer device has an engaged condition and a disengaged condition. The power switching mechanism and the torque transfer device in the disengaged condition are operable to only transmit rotary power to the first vehicle wheels. The torque transfer device in the disengaged condition prevents the first shaft member and the second shaft member from back-driving the ring gear and the pinion of the rear driveline. The power switching mechanism in the disengaged condition prevents the transmission from driving the propeller shaft.

摘要： A turbine blade system for a gas turbine engine includes a turbine blade having a trailing edge region extending in a lateral direction and in a lengthwise direction from a pressure side surface to a trailing edge. The trailing edge region includes a plurality of riblets extending in the lengthwise direction from the pressure side surface toward the trailing edge. The trailing edge region defines a plurality of ejection slots each laterally disposed between two of the riblets. The plurality of riblets each define an upper surface having at least a portion in the lengthwise direction being curved relative to the pressure side surface so as to generally shield the upper surface from a high heat load propagating from the pressure side surface and to facilitate cooling air flowing from the ejection slots to flow over the upper surface.

摘要： A suspension module with a suspension component, wheel hubs coupled to the suspension component, and a drive system. The drive system has a pair of units that selectively provide drive torque to an associated one of the wheel hubs. Each unit includes a motor, a first reduction gearset and an overrunning clutch. The first reduction gearset is disposed between the motor and its wheel hub and multiplies torque output from the motor. The clutch disconnects the motor from the associated wheel hub so that an output shaft of the motor is not drivingly coupled to the associated wheel hub when a rotational speed of the first portion does not exceed a rotational speed of the second portion. The clutch can be selectively operated to drivingly couple the motor to its wheel hub to permit the motor to be back-driven. A method for operating a hybrid power train is also provided.

摘要： A turbine blade cooling system for a gas turbine engine includes a turbine blade having a trailing edge, a concave side, and a convex side. The trailing edge defines at least one set of impingement holes each having a central longitudinal axis which is closer to a nearest portion of an edge of the blade at one of the concave and convex sides relative to a nearest portion of an edge of the blade at the other of the concave and convex sides. Alternatively or in addition to the foregoing, the trailing edge can define at least one set of impingement holes each having a central longitudinal axis which is angled in a direction of a flow of cooling medium toward one of the concave and convex sides relative to the other of the concave and convex sides.

摘要： An article is provided, comprising a structure and a coating for minimizing thermal gradients in the structure. The coating includes a plurality of first layers of thermally conductive material, and a plurality of second layers of thermally conductive material. The first layers of thermally conductive material are less thermally conductive than the second layers at any particular temperature, and the layers are applied to the article such that the second layers of thermally conductive material are distributed amongst the first layers of thermally conductive material. Conduction of thermal energy through the layers to the structure is substantially impeded within the first layers, and substantially laterally dispersed within the second layers, thereby minimizing any thermal gradients within the structure.

摘要： A drive axle assembly has a gear housing, two axle tubes extending outwardly of the gear housing, a lubricant reservoir in the gear housing and a gear assembly rotatably mounted in the gear housing that has a rotatable member that is partially disposed in lubricant in the lubricant reservoir. The drive axle assembly also has a lubricant cooling system that includes a lubricant passage in fluid communication with the lubricant reservoir via an inlet that is juxtaposed the rotatable member so that the level of lubricant in the lubricant passage is raised when the rotatable member rotates. The lubricant passage has elevated outlets that deliver lubricant to lubricant ducts disposed in the respective axle tubes when the lubricant in the lubricant passage rises above a predetermined level. The lubricant flows away from the gear housing in the lubricant ducts and returns to the reservoir along the interior of the axle tubes which cools the lubricant as it returns to the reservoir.
