摘要： A clutched pulley assembly mountable to the shaft of a motor-generator unit (MGU) has a first sheave, with first spline teeth, rotatably mounted to the MGU shaft, and a second sheave, with second spline teeth, fixed to the MGU shaft. A slider gear with slider gear spline teeth is axially moveable between a torque transfer position, where the slider gear spline teeth simultaneously intermesh with the spline teeth of the first and second sheaves to operatively connect the sheaves to each other, and a torque cut-off position, where the slider gear spline teeth intermesh with the second sheave spline teeth but not the first sheave spline teeth so as to operatively disconnect the sheaves. An actuator drives the slider gear between the torque transfer and cut-off positions. The pulley assembly can be used in a stand-cooling mode wherein the engine is stopped but the MGU powers a load.

摘要： Claw-type shifting mechanism (5) with a first sliding sleeve (17) and a fixed coupling element (19). In order to produce a passage, the first sliding sleeve (17) and the coupling element (19) each respectively have at least one recess (31, 35) and at least one web section (32, 36), in which the first sliding sleeve (17) and the coupling element (19) can be arranged together radially on the outside on a first shaft. The first sliding sleeve (17) can be displaced along the first shaft and the coupling element (19) can be connected firmly to the first shaft. The drive arrangement (1) comprises at least one drive machine, a transmission with a first shaft, a second shaft and a third shaft, a housing, and a claw-type shifting mechanism (5) of this type.

摘要： Transmission systems, disconnect mechanisms, and methods of assembling disconnect mechanisms are envisioned. A disconnect mechanism is adapted to selectively decouple a driving device from a driven device. The disconnect mechanism includes a lever, an inner shaft, an outer shaft, and a housing. The inner shaft is coupled to the lever, the outer shaft is coupled to the inner shaft, and the housing at least partially houses the inner shaft and the outer shaft.

摘要： An axle disconnect assembly, including: a housing and a clutch a shaft with first splines; a sleeve including second splines non-rotatably connected to the first splines, and axially extending teeth; a shift lever including at least one pivot pin, a first end connected to the sleeve, and a second end; and an actuation assembly including an actuation shaft engaged with the second end of the shift lever, and an actuator. In a connect mode, the teeth are non-rotatably connected to a power output. In a disconnect mode, the sleeve is rotatable with respect to the power output. To shift from the disconnect mode to the connect mode: the actuator rotates the actuator shaft; the actuator shaft pivots the shift lever around an axis of the at least one pivot pin; and the first end of the shift lever displaces the sleeve, with respect to the shaft, in an axial direction.

摘要： A drive transmission apparatus includes a dog clutch including a dog gear assembly and a dog ring, which are configured for rotation about a rotational axis and relative axial adjustment between an engaged condition in which torque can be transmitted between the dog gear assembly and the dog ring, and a disengaged condition in which torque cannot be transmitted. The dog gear assembly includes a dog gear, a retractable dog assembly configured for movement relative to the dog gear between an extended position and a retracted position, and a control element that controls movement of the retractable dog assembly. The dog ring includes a plurality of first dogs and the dog gear assembly includes a plurality of second dogs that engage the first dogs in the engaged condition, and that are disengaged from the first dogs in the disengaged condition. The second dogs include a plurality of fixed dogs that are mounted on the dog gear and a plurality of retractable dogs of the retractable dog assembly.

摘要： The present invention relates to a generator drive disconnect device, of a generator arranged to be driven by an aircraft engine. The disconnect device comprises: a drive transfer means (1) having a first, connected configuration, and a second, disconnected configuration; a disconnect biasing means (200), configured to bias the drive transfer means to the disconnected configuration; and a fluid cavity (300), configured such that provision of a pressurised fluid in the fluid cavity biases the drive transfer means to the connected configuration.

摘要： An in-vehicle control apparatus is configured to execute a collision degree calculation process of, when it is determined that gear rattle occurs, calculating a collision degree that indicates a magnitude of a collision between a sleeve chamfer and a gear chamfer based on a rotation speed difference between a sleeve and an idler gear, execute an index value calculation process of calculating an index value that correlates with wear and tear of the sleeve chamfer and the gear chamfer based on the collision degree that is calculated each time it is determined that gear rattle occurs, and execute a wear and tear degree calculation process of calculating a degree of wear and tear of the sleeve chamfer and the gear chamfer by integrating the index value that is calculated each time it is determined that gear rattle occurs.

摘要： A transmission that suppresses a tilt of a slider in an axial direction and reduces a dimension of the slider in the axial direction for downsizing is provided. A transmission includes a fifth-speed driven gear disposed on a counter shaft, a fifth-speed driving gear that always meshes with the fifth-speed driven gear and disposed on a main shaft, and a first slider disposed on the counter shaft to be movable in the axial direction in accordance with a shift operation. The first slider includes first dog recesses. The fifth-speed driven gear includes fifth-speed dog projections configured to mesh with the first dog recesses. The fifth-speed driven gear includes a fifth-speed driven gear protrusion only on a location closer to a radially outer peripheral end thereof than the counter shaft. The fifth-speed driven gear protrusion protrudes in the axial direction so as to contact the first slider when the first slider falls in the axial direction. The protrusion length of the fifth-speed driven gear protrusion is smaller than that of the fifth-speed dog projections.
