  • Patent number: 9346561
    Abstract: According to one embodiment, a system for measuring coupling misalignment of a rotorcraft drive shaft includes a reference device and a sensor. The sensor is configured to receive a signal from the reference device indicative of a distance between the reference device and the sensor. The reference device and the sensor are configured to be disposed on opposite sides of a flexible coupling coupled to the drive shaft and disposed between the engine and the pylon. The flexible coupling is configured to rotate with the drive shaft and comprises a flexure portion configured to flex in response to a difference in alignment between the engine and the pylon. A misalignment measurement system may be configured to generate a misalignment value in response to the signal.

  • Patent number: 7801657
    Abstract: A control system for a vehicle having first and second wheels is provided that includes a differential apparatus adapted to distribute torque between the first and second wheels and a traction controller for controlling operation of the differential apparatus from vehicle launch up to a predetermined vehicle speed. The traction controller is configured to engage the differential apparatus in a first operating state according to at least one vehicle operating parameter indicative of a low traction operating condition and to further control engagement of the differential apparatus in a second vehicle operating state during the low traction operating condition according to a difference between an actual vehicle yaw rate and a predetermined target vehicle yaw rate. The control system also includes a stability controller for controlling engagement of the differential apparatus at or above the predetermined vehicle speed.

  • Patent number: 6200220
    Abstract: A slip coupling comprised of a hub with extending flexible vane(s). The vane(s) extend from the hub at an acute angle which allows them to flex when coming in contact with a relatively rotatable friction cylinder. The friction between the vane(s) and the friction cylinder creates resistance to movement. Relative motion between the hub and friction cylinder occurs only when the frictional force between them is overcome.

  • Patent number: 5741187
    Abstract: A flexible shaft coupling in which the torque transmission takes place by way of elastomer shackles between the two shafts to be coupled. The coupling components in the form of separate anchoring plates are all arranged in a single radial plane of the coupling, whereas the radially outward-pointing elastomer shackles are mounted to enclose the coupling. For predetermined torques to be transmitted, this design allows minimal outside dimensions of the flexible shaft coupling, as a result of which these couplings are especially applicable to wheel driveshafts of motor vehicles.

  • Patent number: 4873889
    Abstract: The tie-bar comprises a pair of spaced apart bushings each having end flanges extending from a central cylindrical portion and a through opening for connecting to flexing structures. A plurality of wires comprising bands of parallel wires wrapped endlessly about the spaced-apart bushings provide a tie-bar having bushings disposed at the ends and connected by a pair of spaced-apart side portions of superimposed bands. The wires are coated with a dry film lubricant so that the wires are dry wrapped about the bushings, and then a resin material encapsulated about the dry wrapped wire bands and bushings. A body of resin material disposed between the spaced-apart side portions and the bushings maintains the spaced-apart relationship of the bushings, by withstanding the compressive tension of the tightly wrapped wires. The wires are free to move relative to one another in response to tension and torsional forces exerted upon the tie-bar.

  • Patent number: 4378220
    Abstract: An apparatus is provided for transferring torque from one shaft to another. The shafts (11) and (12) are coupled together using a flexible member, such as an elastomeric spring or belt (23), trained around pins (21) eccentrically mounted on at least two planet gears (19). A sun gear (15) which is connected to one of the shafts (11) meshes with the planet gears. These gears (19) are also connected to the other shaft, (12), either through a ring gear (66) or pivots (27). When one of the shafts is rotated, this causes the planet gears (19) to rotate, and this rotation moves the pins (21) in an arc. This gradual controlled movement of the pins (21) causes the belt (23) to stretch in a manner so that as torque is transferred from one shaft to the other, troublesome torsional vibrations are effectively damped.This energy-absorbing, torque cushioning apparatus is particularly suited for use as a lock-up clutch in motor vehicles.
