摘要： Methods and system are provided for locking a half shaft to a wheel hub to engage four wheel drive are disclosed. In one example, a wheel hub is locked to a half shaft via a radially expanding engagement mechanism. The radially expanding engagement mechanism is without grease and without springs.

摘要： A transmission includes a torque converter with both a variable pitch stator and a bypass clutch. These are controlled in two modes to maintain a target slip speed. In a first mode, the bypass clutch is fully released and slip is controlled by varying the pitch of the stator blades. In a second mode, the stator is held in the tightest position and slip is controlled by varying the torque capacity of the bypass clutch. The target slip is calculated based on a variety of different input signals depending on what type of vehicle maneuver is being performed.

摘要： A power-split hybrid transmission includes a direction reversing mechanism between the transmission input and a power-splitting planetary gear set. The transmission input is driven by an internal combustion engine. Engaging the direction reversing mechanism to drive the carrier in a direction opposite of engine rotation permits the transaxle to achieve higher output torque in reverse when using predominantly engine power. The direction reversing mechanism may also be used to hold the carrier stationary, providing a torque reaction to propel the vehicle with a generator, thus increasing the output torque in both directions when operating under only battery power.

摘要： An electro-magnetically actuated pawl clutch is adapted to establish a fixed overdrive ratio in a powersplit type hybrid gearing arrangement. The electro-magnetically actuated clutch includes an inner race splined to the transmission input shaft and an outer race fixed to a first gear that is supported for rotation about the input shaft. The inner race includes two magnetically separated toothed rings. Electrical current in a non-rotating coil establishes a magnetic field in the inner race. The magnetic field causes a set of pawls to pivot with respect to the outer race and to engage at least one of the toothed rings. The pawls and teeth are designed such that, when engaged, the outer race can rotate faster than the inner race but cannot rotate slower. The first gear meshes with a second gear fixed to the transmission output shaft.

摘要： A continuously variable transmission includes a first shaft driveably connected to a power-plant and having a first pair of sheave disks, and a second shaft having a second pair of sheave disks. A tension member is connected to the first and second pairs of disks such that power is transmittable between the first and second shafts. A third shaft is selectively driveably connected to the second shaft via a clutch. The clutch includes an inner race fixed to one of the second and third shafts, and an outer race fixed to a gear and having an inner surface circumscribing the inner race. At least one pawl is biased to couple the races in a fixed relationship for common rotation. The clutch further includes an electric coil and an armature configured to engage the pawl to decouple the races in response to current being supplied to the electric coil.

摘要： A controllable one-way clutch includes a first race and a second race. The first race has a periphery with a tooth. The second race has a rocker with an associated solenoid. The rocker is pivotable between a first position and a second position. In the first position, the rocker is engaged with the tooth. In the second position, the rocker is disengaged from the tooth. The solenoid has an armature arranged to move the rocker from the first position to the second position and/or from the second position to the first position.

摘要： A transmission utilizes an electro-magnetically actuated selectable one-way-clutch. The one-way-clutch prevents rotation of a transmission member in both directions when a current exceeds a threshold and permits rotation in only one direction otherwise. To prevent un-intended engagement, a switch interrupts the current unless a second current exceeds a threshold. In order to engage the one-way-clutch, both currents are set above their respective thresholds by a controller. In the event of a single fault such as a short circuit, the system continues to function normally. The controller may periodically test for a fault by intentionally setting one current above its threshold and the other below its threshold and determining the state of the one-way-clutch by measuring speeds of transmission elements.
摘要翻译： 变速箱采用电动式可选择单向离合器。 当电流超过阈值时，单向离合器防止传动构件在两个方向上的旋转，否则允许沿一个方向旋转。 为了防止意外的接合，开关中断电流，除非第二个电流超过阈值。 为了接合单向离合器，控制器将两个电流设置在它们各自的阈值之上。 在发生短路等单一故障的情况下，系统继续正常工作。 控制器可以通过有意地将一个电流高于其阈值而另一个电流低于其阈值来定期测试故障，并且通过测量传输元件的速度来确定单向离合器的状态。

摘要： A hybrid transmission includes a permanent magnet rotor which is selectively held against rotation by a one-way-clutch. The one-way-clutch utilizes a pocket plate having a plurality of pawls which engages with an inner race in response to energizing a magnetic coil. The pocket plate is fixed to the rotor shaft and restrains the laminates axially, eliminating the need for one of the end plates.

摘要： A wheel end disconnect system includes an inner race connected to one of an axle half shaft and a wheel hub, an outer race connected to the other of the axle half shaft and the wheel hub, and a plurality of radially actuatable pawls, circumferentially spaced apart, oriented between the inner and outer races, and movable between an outboard locked position and an inboard unlocked position to connect and disconnect the wheel hub from the axle half shaft. The system further includes a plurality of pins attached to an actuator ring. The actuator ring is axially shifi-able between a locked and unlocked position. The system also includes one or more permanent magnets forming a permanent magnet ring attached to the actuator ring, with axially spaced apart north and south poles, and an annular tri-pole electromagnet having two counter-wound axially spaced apart coils concentric with the annular permanent magnet.
