摘要： A variable cam timing phaser for an internal combustion engine having at least one camshaft comprising a housing, a rotor, a spool valve, and a recirculation check valve. The housing and the rotor define at least one vane which separate chambers, advanced and retard. The spool valve comprises a spool having a plurality of lands mounted within a bore in the rotor. The spool is slidable from an advance position through a holding position to a retard position. The phaser also has an advance exhaust passage, a retard exhaust passage, and a return passage to route operating fluid to the chambers. The recirculation check valve is in the return passage and only allows flow of fluid from the advance chamber into the return passage when the spool is in the retard position and fluid from the retard chamber into the return passage when the spool is in the advance position.

摘要： A variable camshaft timing phaser for an internal combustion engine having at least one camshaft comprising a plurality of vanes in chambers defined by a housing and a spool valve. The vanes define an advance and retard chamber. At least one of the vanes is cam torque actuated (CTA) and at least one of the other vanes is oil pressure actuated (OPA). The spool valve is coupled to the advance and retard chamber defined by the CTA vane and the advance chamber defined by the OPA vane. When the phaser is in the advance position, fluid is routed from the retard chamber defined by the OPA vane to the retard chamber defined the CTA vane. When the phaser is in the retard position fluid is routed from the retard chamber defined by the CTA vane to the advance chamber defined by the CTA vane.

摘要： An on demand vehicle drive system monitors vehicle performance and operating conditions and controls torque delivery to the vehicle wheels. The system includes a plurality of speed and position sensors, a transfer case having primary and secondary output shafts driving primary and secondary axles and a microcontroller. The sensors include a vehicle speed sensor, a pair of primary and secondary drive shaft speed sensors, and brake and driveline status sensors. The transfer case includes a modulating electromagnetic clutch controlled by the microcontroller which is incrementally engaged to transfer torque from the primary output shaft to the secondary output shaft. When the speed of either the front or the rear drive shafts overruns, i.e., exceeds, the speed of the other drive shaft by a predetermined value related to the vehicle speed, indicating that wheel slip is present, clutch current is incrementally increased to increase clutch engagement and torque transfer to the secondary axle. When wheel slip is reduced below the predetermined value the current to the clutch is incrementally reduced. The method of operating such a system is also described.

摘要： A variable camshaft timing phaser (10; 110; 210) in which a rotor (12; 112;212) that is secured to a rotatable camshaft is selectively advanced or retarded in position relative to a surrounding rotatable housing (14; 114, 214), the rotor having at least one outwardly extending vane (20; 120; 220) that is received in an inwardly facing recess (18; 118; 218). Pressurized oil is selectively delivered to one of an advance portion or a retard portion of the recess, and simultaneously withdrawn from the other of the advance portion and the retard portion, by adjusting the axial position of an axially shiftable spool valve (22; 122; 222). The spool valve has a null position, and the relative positions of the rotor and the housing are positively locked in position when the spool valve is in its null position by a locking pin (48; 148; 248). The locking pin is resiliently biased towards a locking position by a spring (52; 152; 252), and is urged away from its locking position by pressurized oil from a source.

摘要： A hub is secured to a camshaft for rotation synchronous with the camshaft, and a housing circumscribes the hub and is rotatable with the hub and the camshaft and is further oscillatable with respect to the hub and the camshaft within a predetermined angle of rotation. Driving vanes are radially disposed within the housing and cooperate with an external surface on the hub, while driven vanes are radially disposed in the hub and cooperate with an internal surface of the housing. A locking device, reactive to oil pressure, prevents relative motion between the housing and the hub. A controlling device controls the oscillation of the housing relative to the hub.

摘要： A variable valve actuation (VVA) system (10/210) includes a camshaft (20), having a lobe (22) thereon. A valve (30/230) terminates in a stem end (34/234), and is moveable between open and closed positions along its own longitudinal axis, where the valve is biased toward the closed position. A bucket tappet (40/240) includes a lifter plate (41/241) having a middle portion (44/244) for engaging the lobe of the camshaft on a camshaft side (46/246) of the lifter plate, and for engaging the stem end of the valve on a valve side (48/248) of the lifter plate. The lifter plate includes end portions (50/250/252) on either side of the middle portion, and is translatable by rotation of the lobe of the camshaft to cause movement of the valve along its longitudinal axis toward the open position. Finally, a pivoting device (70/72/80/270) is in engagement with at least one of the end portions of the lifter plate, for pivoting the lifter plate toward the lobe for early engagement therewith, and for pivoting the lifter plate away from the lobe for delayed engagement therewith. The early engagement causes the valve to open prematurely, and the delayed engagement causes the valve to open belatedly.
