sprag clutch การใช้

• The stator was equipped with a sprag clutch enabling it to freewheel when required.
• The sprag clutch simply " lets go " once the reaction force it provides is no longer needed.
• Bands are not applied when drive / overdrive range is selected, the torque being transmitted by the sprag clutches instead.
• Recent improvements in design have replaced the ratchet ( gear and pawl mechanism ) with sprag clutches and disc brake assemblies.
• These were an insecure oil pressure switch and a longer-lived problem with the starter ( or sprag clutch ).
• One-way sprag clutches have also been used for the same purpose, but are generally not adjustable for disengagement force.
• The sprag clutch arrangement would preclude the use of the starter as a generator if employed in hybrid scheme mentioned above, unless modifications were made.
• Eventually, the low turbine matches pump speed, and the low turbine freewheels on a one-way sprag clutch much like on a bicycle.
• The starter's pinion is clutched to its drive shaft through an overrunning sprag clutch which permits the pinion to transmit drive in only one direction.
• A sprag clutch is used in most older automatic transmissions and some newer ones for shifts which require the synchronized engagement of one clutch with the disengagement of another.
• As the huge pendulum below the Clock rocks the Chronophage as he steps round the great escapewheel, each backward and forward movement is used by sprag clutches to wind up the drive spring.
• Some of the technology of the NR750 was carried across to the RC45, These included its fuel-injection system, clutch, sprag clutch and even the 16-inch front wheel size.
• The electronically controlled transmission is designed around a fully articulated Ravigneaux gearset that is controlled by electronically timed application of several range-specific hydraulic clutches, in combination with mechanical one-way sprag clutches.
• The Controlled Coupling HydraMatic incorporated a secondary fluid coupling and a pair of sprag clutches in place of the former friction clutch and brake bands, shifting in part by alternately draining and filling the secondary coupling.
• A one-way sprag clutch is built into the center of the upper sheave to allow the rotor system to continue to rotate in the event of engine failure, allowing the R22 to enter autorotation and land in a controlled manner.
• Early Honda Shadow models used a design wherein a sprag clutch is connected to just half of the clutch friction plates, allowing the clutch to slip during heavy backloading sufficiently to prevent rear-wheel lockup, while still allowing moderate engine compression braking with the remaining friction plates.
• The advantage of this type of clutch is that it eliminates the sensitivity of timing a simultaneous clutch release / apply on two planetaries, simply " taking up " the drivetrain load when actuated, and releasing automatically when the next gear's sprag clutch assumes the torque transfer.
• In the subsequent investigation, the NTSB found that the sprag clutch that was installed in the helicopter, which was on lease to WNBC Radio by Spectrum Helicopters of Ridgefield Park, New Jersey, was a military surplus part which was not designed for use in a civilian aircraft, and that the part had not been adequately lubricated.
